Abstract:The floras of the mainland Asia have been studied for more than three hundred years,however,they are still
incomplete.Progress on the conifers floras from the mainland Asia,a relatively wel studied group,is still less than
expected.The major differences among the different floras in mainland Asia,especialy compared with the world
checklist of conifers,are analysed and discussed;and the related aspects in the traditional taxonomy from mainland A—
sia are also addressed.
Key words:floras;mainland Asia;conifers;review

1 Introduction
Mainland Asia is here definited as the Asian con—
tinent,except for the area covered by Flora Malesiana
(Van Steenis,1951,i.e.southeast Asian islands).T his
is the largest and also the most populous continent in
the world. However。its rich flora is stil1 not cata—
logued well,even though its botany has been explored
for more than three hundred years,both by outsiders
(especialy European and North American scientists)
and by insiders(1ocal scientists from different coun—
tries).In order to get a better picture of the current
status of local floras,we are analyzing the general pro—
gress and situation of the conifers floras from mainland
Asia,and comparing them with those in the recently
published“World Checklist of Conifers”(Farjon,1998,
2001).
As a developing region,mainland Asia is a poorly
understood botanically and its floras are far away from
being completely surveyed,unlike North America or
Europe.It has been studied by 1ocal researchers and
westerners,as well as partnerships between them in
the past three hundred years. In the last century,for
example,there were some famous works like Flora of
British India(Hooker,1875— 1897)and Index Florae
Sinensis(Forbes& Hemsley,1886—1905)from Kew,
and the floras of Chinese Manchuria from Russia
(Komarov,1901— 1907)and Japan(Kitagawa,1939,
1979).In the past half century,there were Flora Irani—
ca from Vienna,Austria(Rechinger,1963),and Flora of
Iraq(from Kew,Townsend,1966),and more recently
the Checklist of Myanmar from Smithsonian Institution
of USA(Kress et a1.,2003),Flore du Cambodge,du
Laos et du Vietnam from Paris,France(Gagnepain,
1960),F1ora of Turkey(Davis,1965—2000),Flora of
Arabian Peninsula and Socotra(Miller& Co pe,1996),
and F1ora of Bhutan(Gerison& Long.1983)from Ed—
inburgh,Scotland.Recently cooperated works between
east and west have become a mode1,for example F1ora
of Thailand(cooperatively produced by Thai Forestry
and Denmark,Phengklai,1972)and Flora of China(co—
operately produced by Chinese Academy of Sciences
cooperated and Missouri Botanical Garden.Wu& Ra—
yen,1 9 94).In addition to the works mentioned above,
there are also some works published by 1ocal research—
ers,such as Chinese Florae Reipublicae Popularis Sini—
cae(Wu& Chen,2004;Polhil,1990;Qian& Ricklefs,
1999;Ma Clemants,2006),the Mi ddle East(Heler
& Heyn,1994)as well as many others from Japan

(Hara et a1.,1978),Korea(Park,2007),and India
(Sharma,1993).
The historical collections of plants specimens play
very important roles in modern flora preparation
(Schatz,2002).The Mainiand Asia,however,is disad—
vantaged in this respect because most early collections
1ie abroad.Examples include Kew’s collections from
India(Rau,1994),Russian collections from central
(Grubov,2001),north(Krasnoborov,2000)and east
Asia(Komarov,1901— 1907),as well as the American
colections(Wu & Raven,1994)and Japanese collec—
tions(Nakai,1 952)from East Asia.In the past three
hundred years,many floras for the colonized parts of
mainland Asia have been published,especially in earlier
years(Kaempfer,1712;Bretschneider,1880,1898;
Hooker,1875— 1897;Lecomate,1916— 1944;Hum—
bert,1938— 1951).Recently more and more work has
been published from 1ocal researchers(Charkevicz。
1989;Czerepanov,1995;Grubov 2001;Hara et a1.
1978;Heller& Heyn,1994;Huang,1994;1watsuki et
a1.,1995;Nasir L Nasir,1978;Ohwi,1984;Rau,
1994;Sharma,1993;Singh& Mudgal,1997;Wu&
Chen,2004;Zohary,1966).However,this vast area is
still poorly understood especially when compared with
floras of the developed world such as Europe and
North America.
2 M ethods and Materials
In order to better understand the flora situation in
the mainiand Asia,we divided it into east,south,west,
central and north Asia,mainiy based on geographic,nat—
ural,and more especifically floristic criteria:East Asia:
from Russian Far Ea st,Japan,through Koreas to Taiwan
and northeast,north,east,south and southwest China,al1
the、^阻y to Himalayan area (itself,sometimes called Hi-
ma layas,including Nepal,Bhutan,as well as northwest
and northeast of India and north of Pakistan);South A_
sia:from Cambodia,Laos,Vietnam ,Myanmar,Thailand
to Bangladesh,India(except northeast and northwest
parts),and Sri Lanka,West Asia:The Arabian Peninsu—
la,Iran Highland,west to Middle East and Turkey as
well as west of Pakistan;Central Asia:Kazakhstan,Kyr—
gyzstan,Turkmenistan,Tadzhikstan,Uzbekistan,Af—
ghanistan as well as northwest China and Mongolia;and
North Asia:the whole Russian Siberia.The most abun—
dant region floristically is in east and south Asia(Qian 8L
Eicklefs,1999),and the most impoverished regions are in
west,central as well as north Asia.
Mainand Asia includes more than 25 countries or
regions,we chose all of their current floras(if not availa-
ble,a checklist instead)as the basic unit for our stafs—
tics.Each of them is treated as a lOcal flora.The coni—
fers,as we define here,are the two classes recognized by
the recent world checklist of conifers(Farjon,1998,
2001),i.e.Coniferopsida and Taxopsida.All local floras
are listed alphabetically if there are any conifers treated,
and compared with theⅥrOrld Checklist of Conifers pub—
lished recently(Farjon,1998,2001)in order to analyze
(see Table 1,The list and comparation of the conifers in
mainland Asia,for detail).
Here is listed the detailed information of each lo—
cal flora used in this work alphabetically wi th their
three—letter abbreviations,their publication introduction
and brief comments:

published by The Israel Academy of Sciences and Hu—
manities.It covers the entire West Asia,from Turkey
to Arabian Penisula,with a name Iist and their distri—
bution information,completed by local scientists about
fifteen years ago. It was a little out of date even
though there is not much to be added.More impor—
tantly,this is the only local information for the whole
area.Total,there are 7 genera,20 species and 4 in—
fraspecies(both subspecies,varieties and forms are
treated as infraspecies,same as below).

western countries.However,not al of the information
provided is complete or perfect because this country is
believed to be one of poorest understandings of their
own floras among al1 countries in mainland Asia.1、O—

from Paris(Gagnepain,1960,Lecomate,1916—1944).E—
yen the Conifers published about 10 years ago has been
changed now,and some new taxa have been described
more recently from North Vietrmm(Averyanov et a1.,
2002;Bond,2002;Fa~on et a1.,2002;Thomas et a1.,
2007).This work in fact is a new edition of the old one,
which was published more than half a century ago.TO—
tal,there are 16 genera,29 species and 1 infaspecies.

Chinese edition of Flora of China,known as FRPS,the

than that of any other country in the world.The treat—
ment of conifers for Flora of China English edition is a
little better than that in the a nese edition,with more
broad species concept.However,many discrepancies still
exist between the treatment and world checklist,such as
different nalTles for some species and infraspecies,espe—

few others in Korean(Yi,2002),and the treatments on
taxa in this flora are also very good and updated great—
ly,especially compared with the concepts of genera and
species by others(Yi,2002).Total,there are 1 1 genera

3 Discussion
The concepts of plant taxa used by the different au—
thors from different institutions or countries。are still
very different from each other,even simply within coni—
fers from mainland Asia.At the fami ly 1evel,Taxodiace—
ae and Cupressaceae have been merged since the 1970s
(Eckenwalder,1976;Fa~on,1998,2001),but the merge
has never been accepted in any local floras in mainland
Asia.No statement or proposal about the disagreement
has been ma de from any local works among more than
6期 马金双等:亚洲大陆植物志中的针叶树评述 717
20 1ocal floras in mainland Asia mentioned in this work.
The only feasible reason for this is that some traditional
works,which we have cited here,are too familiar with
their old concepts of separation between these two fami —
lies so they do not want to change it,especially since
most genera of Taxodiaceae are mainly from Asia.Evi—
dently,further work regarding this should be reconsid-
ered since foreign and local taxonomi sts have not reached
an agreement.At the genus level,problem concerning
concepts are also unresolved. In fact,they are even
worse than those at the family 1eve1.There were many
disagreement at this leve1.such as Platycladus(Fu&
Li,1999),an endemic genus from Chirib,which has been
used as rh~ja,even under cultivation(Grubov et a1.,
2002;Czerepanov,1995;Hiep& ⅥdaI,1996).Another
example is Sabina,synonymus under Juniperus(Farjon,
2001),used in mordern Japanese Flora(Yamazaki,
1995).The same situation is faced in Nageia(Farjon,
2001;Fu& Li,1999),which some have put it under
Podocarpus(Yama zaki,1995;Phengklai,1975).Finally,
Nothotsuga(Fatjon,1998,2001),an endemic genus to
China,has never been accepted in FI)C itself,but under
Tsuga(Fu& Li,1999).These issues of splits or merges
have been debated for a long time by different authors,
especially from different countries.
At the species level,we need much more work on
the concept of‘senso.Iato. to‘senso.striato. ,the most
disputed point worldwide in taxonomy.In some parts,
this is even worse than the above discussions at the ram-
ily and genus levels since it frequently happens.Exam-
pies of these arguments can be found among following
taxa:1,Keteleeria,with 3 species and 1 variety recog—
nized by Farjon,but 5 species and 4 varieties recorded
from China alone by FOC(Fu& Li,1999),and disagree—
ment rate up to 66%(6 difference among 9 entirely ac—
cepted both species and infaspecies by local floras,see
table 1 for detail);2,Pseudotsuga,with 2 species and 2
varieties from ma inland Asia,but 3 species and 1 variety
recorded in FOC(Fu& Li,1999),and disagreement rate
up to 75 (3 to 4);3,Torreya,wi th 3 species and 3 vari—
eties in mainland Asia,but disagreement rate up to 42.
86 (3 to 7);4,Tsuga,only 5 species and 2 varieties in
mainland Asia,but disagreement rate up to 41.18 (7 to
17);5,Podocarpus,with 9 species and 2 varieties from
ma inland Asia,but disagreement rate up to 40.5 (15 to
37);and 6,Lar/x,with 7 species and 7 varieties from
mainland Asia,but disagreement rate up to 39.4%(13 to
33).The most interesting thing is that al these disa—
greement are mainly from east As ia,i.e.,from F()C,R
as wel1 as VPR,the most conifer-rich region in the
world.
4 Summary
Mainland Asian floras have been explored for a
long time;however,we stil do not know them very
well,even some of the best known taxa ,Corfifers. In
fact,the folowing countries are without any flora at all
in their history:Myanmar,Mongolia,and Nepa1.Some
have no modem floras,or at least no complete flora yet,
such as India,even they have tried several times but no
published so far for this vast country(Jain,1978—1999;
Sharma,1993).From the financial point of view,they do
not have the proper resources,but India also lacks a kind
of comprehensive ability to produce its own floras with—
out any help from the outside.Flora of India has been
begun several times,even though started several times
since Bentham and Hooker era(Jain,1978—1999;Shar—
nqa,1993).However,no one could finsh the whole pro—
ject.The same goes for the Flora du Cambodge,Laos et
Vietnam(Morat,1960)from Museum Nationa1 d’His—
toire Naturelle,Paris,which ha s been studied for more
than a century. rtunately。it wi lI take another cen—
tury to treat all rema inng taxa at the current rate.In
the north,much area has been covered by the Flora U
S.S.R as well as the replacement floras of the former
SO et Republic such as Flora of Siberia(Krasnoborov,
2000),and Plantae Vasculares Orientis Extremi Sovietici
(Charkevicz,1989),but their concepts are mainly from
the Komarovian scholars.Thus,it is still far away from
a complete understanding and a worldwide acceptance in
the taxonomic field.In the west and central Asia,it is so
varied in topography,geography and politics that no
complete attempt has been ma de yet,only a sma l area,
formerly Russian part,has been covered(Czerepanow,
1995),or Iran et a1.,by Flora Iranica(Rechinger,1963).

The best case in mainland Asia is east Asia,which has
been covered very well in the past few decades,by their
works such as Flora of Japan(1watsuki et a1.,1995),
Flora of China(Wu Raven,1994),Flora of Taiwan
(Huang,1994),Flora of Bhutan(Grierson Long,
1983),Florae Reipublicae Pop~aris Sinicae(Flora of Chi—
na 。Chinese Edition,Ma& Clemants,2006)and many 1o—
cal floras within China(Ma et a1.,2000;Liu et a1.,2007)
and Japan(Editorial Committee of The Journal of Phyto—
geography and Taxonomy,2002).Also,there are some
new floras from this area in preparation,such as Flora of
Korea(Im,1999;Park,2007)and Flora of Nepal(Watson
&Blackmore。2003).
Mainland As ia is the modelTl distribution center of
Conifers(contreas-Medina& Vega,2002;Fa~on,1998,
2001).There are 8 families,69 genera,653 species and
187 inDaspecies of conifers in the world(Farjon,2001),6
fami lies,35 genera,192 species and 92 infraspecies are
distributed in mainland Asia,and 17 genera are endemic
to this area:Ammentaxus,Cathaya,Cephalotaxus,
Cryptomeria,Cunninghamia,Fokienia,Glyptostrobus,
Keteleeria,Metasequoia,Microbiota,Nothotsuga,Platy—
cladus,Pseudolarix,Pseudotaxus,Sciadopitys,Taiwan—
ia and Thujopsis-almost half of the total genera from
mainland Asia(represented by 48.57 ),the highest
percentage of endemi c conifer genera in the world.In
fact,most of them are endemi c to the region of east A—
sia,which has been recognized as the richest floras in the
world(Wu& Raven,1994).Besides this,six genera are
also shared between east Asia and north America:Calo—
cedrus,Chamaecyparis,Pseudotsuga, a,Torreya
and Tsuga,which represents a great floristic diversity
and close affinity between these two continents. The
most poorly understood floras from mainland Asia are
those of less developed areas,according to their different
percentages(see table 1 for detail)compared with the
world checklists of Conifers(Farjon,1998,2001),such as
Russia(41.37%,24 to 58),China(29.91 ,67 to 224),
Myanmar(25.81 ,8 to 31),Japan(25.45 ,14 to 55),
and Nepal(25%,4 to 16).In fact,some diferent per—
centages ma y be even higher than those above since they
do not have complete information.For example,Caloce一
&us and Dacrycarpus are not recorded in CLM(Kress et
a1.2002)even though these have been recognized world—
wide(Farjon,2001;Fu& Li,1999).
In short。the mainland Asian flora is stil1 under de—
velopment.The basic resources needed for flora prepara—
tion,such as herbarium colections,1ibrary accumulations
and trained taxonomi sts,are still far behind their modern
counterparts in North America or Europe.There is still
a long way to go even in the new century for the taxono—
mists from ma inland Asia.Currently,only Israel and Ja—
pan can afford to go further beyond their own boundaries
in preparing floras or for further plant exploration.
There is not enough solid financial suppoK or coopera—
tion between even the closest neighbors,such as China,
India and Indochina.E~dently,taxonomi c work of ina—
inland Asia by western countries will continue to play a
major role in the flora preparation and production by
helping them to finish their floras.More cooperation
from Europe and North America with mainland Asia is
greatly appreciated,expected and encouraged,not only
because of their history,but also for the information we
share in the future in order to under our floras better
than before(Orchard,1999).
Last,but not least,the situation of traditional tax—
onomy in Asia is facing a very serious challenge today.
Some cases are even worse than what one can image or
expect.Recently,traditional taxonomy has lost their
priority to the molecular works worldwide.Basic her—
barium facilities have lost their solid support in com—
parison with the past,and even the largest herbaria and
best institutes in Asia are no exception,such as TI and
PE.W ithout that priority and support,we cannot
hope to complete the basic information of the
biodiversity and conservation worldwide.
