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

The present paper aims at clarifying the identity of Asplenium varians Wall. and its related species for the forthcoming Flora of China vol. 4. Wide-spread in the northern, north-western and south-western parts of China and adjacent regions and growing in exposed rock crevices is the group of ferns in question, which has hi-
therto been taxonomically confused in the botanical literature. Many distinct and related species were previously identified as Aspl. varians, a most wide-spread fern with very variable fronds which may vary from 10 to 30 cm in height and from simply pinnate to fully bipinnate in the degree of pinnation in a single clump under different habitats. 相似文献

Shu‐Ching Lee 《Gender and education》2011,23(1):47-58
The dramatic changes during the past 20 years in Taiwan offer a good example of how gender policy in education is facilitated by a combination of interrelated economic, political and social forces. Taiwan’s policy on gender education emerged from the interaction of state, education, academic and non‐academic feminist positions in reforms. This paper demonstrates – first, the importance of the socio‐political contexts in which reform was proposed, and second, the actions of feminists in making best use of the opportunities thrown up by a confluence of social factors. The social, economic and political transformations of the 1980s saw the rise of a ‘new’ state both supposedly and in reality more responsive to the needs of non‐profit organisations. In testing out relationships of partnership with the state, feminist activists saw the deregulation of education as an opportunity to get women’s issues on the agenda. These reforms were catalysed by a series of social events bringing together supporters in a mood of celebration, protest or mourning specifically in response to particular events. The struggles, contentions, and negotiations that underlay the eventual approval of gender reform in education are illustrated. 相似文献

马克思确立的历史唯物主义,自创立之初开始,就遭到各种非议或责难.有人认为马克思没有批判哲学,只有实证科学,其突出表现为马克思的社会经济理论.而实际上,这些肤浅的理解显然是忽视了马克思哲学的革命性变革,原初的历史语境和时代使命赋予了马克思历史科学的实证批判性. 相似文献
