The object of this paper is to deal with the taxonomical problems of the family
Aspidiaceae from the mainland of Asia. In recent years I have had the opportunity to
study copious materials of the family from this region, and recognized the following nine
genera, namely, Lastreopsis Ching, Ctenitis C. Chr., Ctenitopsis Ching, Pleocnemia Presl,
Arcypteris Underw., Tectaria Cavanilles, Quercifilix Cop., Hemigramma Christ and
Pteridrys C. Chr. et Ching.
The members of this family are middle-sized, terrestrial ferns; rhizome erect or sub-
erect, dictyostelic, scaly; leaves tufted, generally uniform, simple pinnate to tripinnatifid;
veins free or anastomosing, forming areoles with or without free included veinlets; rachis
and costa raised on the upper surface, and, as a rule, covered with pale brown multi-
cellular articulate hairs (ctenitis-hairs); sori round or in a few cases acrostichoid; indusia
reniform, or in some genera absent; spores bilateral with perispore.
Dryopteridaceae and Lomariopsidaceae are closely related to Aspidiaceae, and both
were placed in the latter family by the fern students in the past. The main differences
of Dryopteridaceae from Aspidiaceae are: leaves pale green when dried; costa and costule
grooved and free from articulate hairs (ctenitis-hairs) on the upper side; veins free or
very rarely anastomosing (venatio cyrtomii). In general appearance the genus Ctenitis
of Aspidiaceae is very similar to the bipinnate species of Dryopteridaceae, such as
Dryopteris filix-mas (Linn.) Schott, but its costa and costule are raised and covered by
ctenitis-hairs on the upper side, and the leaves turning dull brown when dried, so that
it has no difficulty in distinguishing the genus from the true Dryopteris. The recognition
of the free-veined Ctenitis and its allies as the primitive tectarioid ferns is very important
in delimiting both Aspidiaceae and Dryopteridaceae, which were all mixed up in the past.
Moreover, from the standpoint of plant geography, these two families are also distinct,
for the Dryopteridaceae are mainly ferns of the temperate regions and the mountains in
subtropics in the Northern Hemisphere, but the Aspidiaceae are pantropical by origin.
The chief differences of Lomariopsidaceae from the Aspidiaceae are: rhizome creeping or
high-climbing; leaves strongly dimorphous, free from the ctenitis-hairs; sori acrostichoid.
That Holttum has made Aspidiaceae a subfamily Tectarioideae of the family
Dennstaedtiaceae proves to be very unnatural, because there is hardly any affinity be-
tween the two families; while Aspidiaceae of Copeland is a terrible mixture of Thely-
pteridaceae, Athyriaceae, Dryopteridaceae and Aspidiaceae (sen. strict.) and a few other
families, for even he himself admitted that no one can use the definition to identify any
unknown members of his family.
Finally, I feel grateful to my teacher, Professor R. C. Ching, for his constant encou-
ragement and warm guidance received both in the course of my study and in the prepara-tion of the present paper. 相似文献

eterachopsis was proposed by the senior author as an independent genus of
the family Aspleniaceae in 1940 with 2 species. Since then much study on its morpho-
logy, anatomy, gametophyte and palynology has been carried out by Nayar, Bir, Chan-
dra & Nayar and Chang et al., and they are of the opinion that the genus like Ceterach,
is a comparatively primitive element in the family Aspleniaceae. The queer zigzag pa-
tern of cutting of lanceolate fronds appears extraordinary in the family Aspleniaceae,
and also suggests its antiquity in evolution. So far only 3 species (C. dalhousiae, C.
paucivenosa and C. magnifica) are recognized, the former from W. Himalayas, also
known from Africa, while the latter two from W. S. China (Yunnan). However, in
the past forty years the Chinese botanists have discovered 2 more species as new in N.
W. Yunnan, thus bringing the total known species of the genus up to 5. The present
paper is a brief summary on the genus Ceterachopsis, which will be published in detail
in the Flora Sinica vol. 4.
Pteridologists are also divided in their views regarding the generic status of Cete-
rachopsis with 5 well-defined species in Yunnan and the East Himalayas. We prefer
to mintain it as a genus separate from Asplenium on account of its distinct morpholo-
gical features. It is to be hoped that more species may come to light in the mountainsin N. W. Yunnan through further exploration now under way. 相似文献

The fern genus Diplaziopsis C. Chr. of Index Filicum has long been considered as
a monotypic one, with the sole species, D. javanica (B1.) C. Chr. from tropical Asia. In
1906, H. Christ described a second species, Allantodia cavaleriana Christ (=D. cavale-
riana C. Chr.) from Kweichow, West China, but this was since not fully recognized by
fern students in general, being often considered as a variety of the first species. This
is certainly a mistake, as is shown by ample herbarium specimens today. In the recent
work on the genus, the writer has found among the herbarium material two additional
new species from China, thus bringing the genus up to four species in Asia, mainly from
China, where, as it is, the genus has its center of development from the long past.
Phylogenetically, Diplaziopsis C. Chr. represents one of the offshoots from the great
stock of diplazioid ferns, of which the genus Diplazium Sw. constitutes the main body
of the group and from which our genus differs chiefly in its leaves of a thin texture with
reticulated venation, but not so much in its type of indusium as it has generally been
emphasized by most botanists in the past, for, as it is, the type of indusium in Di-
plaziopsis also prevails in many species of Diplazium, for which C. B. Clarke (Trans.
Linn. Soc. ser. 2, Bot. I:495, 1880) created, but really superfluously, a subgenus Pseudal-
lantodia, about which the writer will dwell in another paper in the near future. Suffice
it to say here that the indusium in Diplaziopsis as revealed by the species treated here
is, indeed, typical of diplazioid ferns, only often, as it happens, with its adaxial edge
pressed so tight under the expanding sorus that it is unable to open freely along its upper
free edge and, as a result, its thin vaulted back bursts open from the pressure of the ex-
panding sorus underneath.
As a result of the present study, following four species of the genus have been re-
cognized.
Diplaziopsis javanica (B1.) C. Chr. Ind. Fil. (1905) 227.
Wide spread in tropical Asia, northwardly to Bakbo and the southern part of Yun-
nan, China.
D. cavaleriana (Christ) C. Chr. Ind. Fil. Suppl. I (1913) 25.
Ranges from West China through northern part of Fukien of East China to Japan.
D. intermedia Ching, sp. nov.
Endemic in West China: Mt. Omei, Szechuan, and Kweichow.
D. hainanensis Ching, sp. nov.
In conclusion, it may be pointed out that with the modern plant taxonomy pursued
in a more efficient manner than in the past, and especially by the introduction of the
cytotaxonomic methods, the so-called “monotypic genera”, as conceived by the orthodox
systematists, will continue to prove, to a great extent, to be lack of enough scientific
ground. The fact that the “monotypic genus” of Diplaziopsis C. Chr. is now found to
be a genus of four well-defined species is once again an instance to illustrate the pointat issue. 相似文献

Sonneratia, a small genus of Sonneratiaceae, is widely distributed throughout
SE. Asia, E. Africa and N. Australia, extending from 18˚S. to 20˚N. and from 45˚ to
150˚E. In China it occurs only in the Hainan Island. In this paper, two new sections areproposed and six species are recognized, of which one is described as new. 相似文献

After having examined all specimens of the genus Prenanthes L. of Compositae in
the Herbarium of Institute of Botany, Academia Sinica, I find that the classic concept on the
genus Prenanthes established by G. Bentham in 1873 has not been held exactly by some of Euro-
pean, American, Japanese and Chinese botanists. For example, W. B. Hemsley, S. T. Dunn, A.
Franchet, S. Kitamura and C. C. Chang placed plants from China which belong to other groups
into the genus; I also find that the classic concept of the genus is not clear. The present paper
makes a revision not only on the classic concept of the genus, but also on its concept assumed by
the above-mentionded botanists.
With the combination of numerous (25-35), white or yellow ligular florets, numerous ribs
of achenes, Prenanthes alba L. (Nabalus albus (L.) Shih, comb. nov.) is distinctly different
from Prenanthes purpurea L., which has the combination of purple, few (5-15) ligular flo-
rests and few ribs of achenes. Nabalus Cass., as a genus established early (1825) by H. Cassini,
should be restored. It is not reasonable to treat Nabalus as a subgenus (E. B. Babcock et al.
1947) or a section (S. Kitamura, 1956) or as a synonym (G. Bentham, 1983) of the genus
Preanathes L.
The present author recognizes seven species in the new revised genus Prenanthes L. in
China, 4 of which are described as new. In the genus Nabalus Cass. only one species, N.
ochroleuca Maxim., is distributed in Northeast China.
As Lactuca melanantha Franch. (1895), Prenanthes henryi Dunn (1903), P. glandulosa
Dunn (1903), Lactuca triflora Hemsl. (1888) (it was transferred to Prenanthes L. by C. C.
Chang in 1934), Prenanthes formosana Kitam. (1934) and P. wilsoni Chang (1934) all have
campanulate involucres, purple phyllaries, purple dorsi-ventrally compressed achenes, longitu-
dinal rids 6-9 on each side of achene truncate and beakless at its apex and pilose tubes of co-
rollae, they should be placed neither into the genus Prenanthes with obtusely tri-or pentagonous,
subterete achenes and glabrous tubes of corollae, nor into the genus Lactuca with beak achenes.
Besides the above-mentioned species misnamed by some of foreign and Chinese botanists, 6 other
species also have the same structure in achenes and corollae. Evidently, they fall into a new
genus with the name Notoseris Shih.
The new genus Notoseris Shih of the tribe Lactuceae of Compositae seems to be more re-
miniscent of Lactuca L. than of Prenanthes L. emend.
All the 12 species of the genus Notoseris Shih are endemic to China and distributed in the
area of south of Yantze River. Of them 6 are new combinations and 6 are described as new. 相似文献

Almost no differences are seen in habit and infrescence between the gene-
ra Vladimiria and Dolomiaea; the former that was founded on the basis of Jurinea sal-
winensis Hand.-Mazz. by Iljin should be transferred to the later that was earlier found-
ed on the basis of D. macrocephala DC. by De Candolle. But considering the style which
has fine, spreading and apex-acute branches in the group Vladimiria, it is reasonable
to treat the group Vladimiria as a section in the genus Dolomiaea, i.e. Dolomiaea sect.
Vladimiria (Iljin) Shih. Therefore, the genus Dolomiaea is expanded in the circums-
cription in the present paper, not only including the primary group with short, com-
pact and apex-rounded style branches, i.e. Dolomiaea sect. Dolomiaea, but also sect. Vla-
dimiria (Iljin) shih with different characters of style-arms.
Nine species and 1 variety as new combinations are listed in the sect. Vladimiria
(Iljin) Shih as following: D. denticulata (Ling) Shih, D. forrestii (Diels) Shih, D.
scabrida (Shih et S. Y. Jin) Shih, D. souliei(Franch.) Shih, D. souliei (Franch) Shih
var. mirabilis (Anth.) Shih, D. berardioidea (Franch.) Shih, D. georgii (Anth.) Shih,
D. edulis (Franch.) Shih, D. salwinensis (Hand.-Mazz.) Shih and D. platylepis (Hand.
-Mazz.) Shih. 相似文献

About 22 species of the genus Scorzonera L. are so far known to occur in China.
Among them, S. pamirica Shih is described as new and 3 species, S. tau-sahyz Lipsch. et Bosse,
S. pubescens DC. and S. transiliensis M. Pop., are new records to China. Four names in the
literature are reduced to synonyms,and some wrong identications in Chinese botanical literature
are pointed out in this work. Some species with considerable variation in morphology, such as,
S. pseudodivaricata Lipsch. and S. sinensis Lipsch. ex Krasch., are also discussed here. 相似文献
