1 Introduction
Quercus acuta Thunberg is native to southern Ko—
rea and Japan (Ohashi et a1．，2006a；Ohashi et a1．，
2006b)．Other floristic works record its distribution in
East China and Taiwan (Camus，1934 —— 1954；
Menitsky，1984；Frodin 8L Govaerts，1998；Ohba，
2006)．In contrast，in the latest loea1 floristic works of
mainland China and Taiwan，Q acuta is absent(Hsu et
a1．，1985；Liao，1996；Huang et a1．，1999)．Ohashi et
a1．(2006a)concluded that records of Q acuta in China
and Taiwan were based on misidentifications．But re—
markably，Ohashi et a1．(2006b)excluded one specimen
(Konishi 17)collected from Taiwan，which differed
only slightly from Q acuta in the number and promi—
nence of the secondary veins，without mentioning
which species this specimen should be attributed to．
Also their survey only covered specimens in Japanese
herbaria，without other records from the main herbaria
in China or Taiwan．Therefore，their conclusion is not
totaly convincing．The puzzle on the distribution re—
cords of Q acuta from China is stil1 not well resolved
and the diagnostic features of Q acuta and its affinities
seem ambiguous．
The goal of this paper，based on a comprehensive
survey of specimens in the main herbaria，is to clarify
the distribution records of Q acuta in China and to ex—
plore more comparatively stable diagnostic features for
the taxonomy of Q acuta and its affinties．
2 Method and Results
Specimens housed in the main herbaria of China
(PE，KUN，IBSC，IBK，BFC，SZ，SYS，SFC)were ex—
amined．The results showed that the most specimens
of Quercus acuta were collected from Japan，but also
that four specimens collected from HongKong and
Guangdong should be attributed to Q acuta(Fig．1)．

4 Discussion and Conclusion
The specimens collected from Guangdong and
Hongkong (W．Y．Chun 107591 and W．Y．Chen
10232，10232A)were firstly examined by Dr．Chun W．
Y．with a determinate label as“Quercus hongkongen—
sis，n．sp”．Metcalf(1942)cited these specimens as
“Q“Prc“s sp．nov．”in F1．Fukien which indicated that
he thought these specimens were belonging to a new
species，but no any valid names were published based
on these specimens． According to our research，we
conclude these specimens should be attributed to Q
acuta Thunberg．
The related species Q acuta Thunberg，Q．nubiurn
Hand．一Mazz．(now Q．sessilifolia Blume)and Q moHi
Hayata were grouped into“Series Acuta”(Camus，
1934—1954)，“Group Acuta”(Barnett，1944)，“Section
Acuta”(Menitsky，1984)or“Subsection Acuta”(Deng，
2007)by uniform features of the deeply cup—shaped
cupule with dense gray or yellowish pubescence on the
outside of the cupule wall，which covers half of the o—
void acorn，the prominent convex style base(Ba rnett，
1944；Camus，1934——1954) and the scattered simple
stellate and two-armed hairs，but without any glandular
trichomes on the lower lear lamina(Menitsky，1984；
Deng，2007)．The grouping of Q．acuta and Q．sessili一
{olia as a clade is also supported by 9 6 bootstrap value
of the latest ITS based molecular phylogeny of Quercus
subgenus Cyclobalanopsis(Deng，2007)。Meanwhile，a
series of differences exists and can serve as diagnostic
features for these three species．
The leaf blades of Q．acuta and Q．morii are ob—
long to ovate with a primary vein，regular secondary
veins and reticulate on
have a long petiole(2．
the abaxial surface．Both species
0—3．1 cm)．All of these char—
acteristics are different to the oblong-eliptic to lanceo—
late-eliptic leaves with inconspicuous secondary veins
and distinct recurved margin in Q．sessilifolia．The en—
tire or undulate distal half of the leaf margin of Q acu—
ta is different from the margin of Q morii，which is
serrated in the mi ddle and distal portions．
Key to the species in sect．Acuta(Camus)Menitski
