Abstract: Based on herbaria collections, three species of the fern genus Dryopsis ( Tectariaceae) are recognized from
Guangdong Province, China . They are D. heterolaena, D. mariformisand D. maximowicziana . Among thethree species,
D. mariformis and D. maximowicziana are new records to Guangdong . In the newly published book, Flora of Guangdong
Volume VII , the name Ctenitis apiciflora (Wall . ex Mett .) Ching ( = D. apiciflora (Wall . ex Mett .) Holttum & Ed-
wards) instead of D. heterolaena is recorded duetomisidentification . Themorphological andecological differences between
D. heterolaena and D. apiciflora are discussed . A key to thethree species, habitat and distribution data onthe three spe-
cies are given .
Key words: Dryopsis; New record; Taxonomy; Guangdong
Thefern genus Dryopsiswas established by Holttum& Ed-
wards (1986) , whoraised the subgenus Ctenitis subgen. Dryopsis
Ching to generic rank . Morphologically and ecologically,
DryopsisHolttum& Edwards is closer to DryopterisAdans . than
to Ctenitis C .Chr .(Holttumand Edwards, 1986 ; Dong andLu,
2001) .
In thetreatment of Ctenitis C . Chr . for Flora Reipublicae
Popularis Sinicae 6 ( 1 ) (Wang, 1999 ) , the section Ctenitis
sect. DryopsisChing instead of thegenus DryopsisHolttum& Ed-
wardswas adoptedand no species in this groupwas recorded with
distribution in Guangdong Province .
The fern flora of Guangdong was newly come out by Wu
(2006) . Wu recognized Ctenitis apiciflora (Wall . ex Mett . )
Ching in Guangdong . When checking the voucher specimen of
this species fromGuangdong in IBSC , I found the only voucher
was C . Wang 44354 ( IBSC , KUN) . In fact, the specimen C .
Wang 44354 had been cited under thename Dryopsis heterolaena
(C . Chr .) Holttum& Edwards by DongandLu (2001) . Myre-
checkingthe specimen showed that Wu′s naming it C . apiciflora
is amisidentification, the differences between thetwo species are
discussed later on . In addition, twoother species, D. mariformis
(Rosenst .) Holttum& Edwards and D. maximowicziana (Miq .)
Holttum & Edwards, areturned out tobe new records to thefern
flora of Guangdong .

This species is distinctly distinguished from D. apiciflora
(Wall . ex Mett) Holttum& Edwards by pinnules, at least those
on basal pinnae, deeply lobed, costae covered by typically bul-
late scales and sori on thewholepinnules . Contrastively, D. ap-
iciflora is different in pinnules usually entire, flat and ovate or
slightly bullate scales on costaeand sori only on the apex of pin-
nules . Ecologically, D. heterolaena occurs in evergreen broad-
leaf forest and needle and broad-leaf mixed forest at 800 - 2 300
m, while D . apiciflora tendstogrowing inneedle- leaf forestsat
1 800 - 3 300 m .
