苍山蕨属的研究

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.

中国耳蕨属高山耳蕨组的分类学研究

 高山耳蕨组的成员是中国西部、印度北部和喜马拉雅山区常见的蕨类。其成员为夏绿植物,叶片 薄而柔弱。秋季叶片枯萎后叶柄基部宿存在地面形成一个丛堆以保护幼芽,这显然是对高山严峻环境 的适应。作为高山地带特有类型,1972年日本蕨类学家Sigeru Daigobo将它们作为耳蕨属下的一个组 ——高山耳蕨组Sect．Lasiopolystichum Daigobo,这是合理的。Daigobo建立此组时只包含3个种,经过 对中国大量标本及有关文献的研究,现知在中国约有30种应归人此组,其中有3新种:红鳞耳蕨P．ru- fopaleaceum,石生耳蕨P.saxicola,康定耳蕨P．kangdingense;2新变种．裂叶耳蕨P．sinense var．loba- tum,条裂耳蕨P．mollissimum Var．laciniatum;1新组合,钝裂耳蕨P．integrilobum(Sorolepidium)。据羽片背面的小鳞片类型可将高山耳蕨组划分为2个系:穆坪系Ser．Moupinensia和中华系Ser．Sinensia。     

蹄盖蕨科的亚科划分

 蹄盖蕨科的建立对蕨类植物的分类起了很大的推动作用，然而，即使按秦仁昌的狭义概念，它仍然是一个极其复杂的大科。自秦仁昌把该科划分为21个属以后，属级水平上的分类问题比较清楚了，但亚科、亚属和组的划分至今仍不成功。本文主要根据该科三个染色体基数X=42、41和40，结合孢子囊群着生的位置及其它形态特征，将其划分为3个亚科：冷蕨亚科、蹄盖蕨亚科和双盖蕨亚科。     

海桑属的新分类群

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.     

The maturation of global corporate R&D: Evidence from the activity of U.S. foreign subsidiaries

This study empirically investigates the impact of foreign country factors like market size, technological strength of industries, and science and engineering (S&E) capability on the conduct of U.S. overseas R&D during the 1991-2002 period. We find that overseas markets primarily predict the entry of U.S. R&D, while the S&E capability of nations is strongly correlated with the post-entry intensity of U.S. foreign subsidiaries’ innovative activity. We also find important inter-industry differences: U.S. electrical, electronics, computer, and telecommunication industries are strongly drawn towards overseas S&E capacity; industries including Machinery, Automobiles, and Transport equipment are primarily attracted by the technological strength of foreign industry; U.S. R&D in Chemicals mostly follows overseas markets. We discuss the implications of our results to the global organization of innovative activity and innovation policy.

中国拟兰亚科的研究

Apostasioideae, a small subfamily of Orchidaceae, is largely distributed in tropical Asia with its northern limit extending to the Ryukyu Islands and south China. The first Chinese species of this subfamily was reported by E. D. Merrill (1927) based on a specimen collected from Hainan (McClure 9519, AMES), which he regarded as Apostasia wallichii R. Br. As later labelled by E. F. de Vogel, it is in fact identical with A. odorata Bl., a widespread spe- cies also found in southern Guangdong, Guangxi and Yunnan of China.  It was not until re- cently that the true A. wallichii was collected from southwestern Yunnan bordering on Burma, which is initially reported here.  In addition, an interesting new species, A. ramifera S. C. Chen et K. Y. Lang, is described from Hainan.       The only Chinese species of Neuwiedia has long been known as N. veratrifolia Bl. (of. Iconographia Cormophytorum Sinicorum 5: 602, t. 8034. 1976, and Flora Hainanica 4 180, t. 1078. 1977), which, however, was considered by de Vogel (1969) to be not found in China.  In de Vogel's revision, no Chinese taxon but a variety, N. zollingeri Rchb. f. var. singapureana (Baker) de Vogel, is cited with some doubt based on a specimen of Hainan (F. C. How 73122, in young fruit, AMES). N. zollingeri var. singapureana is in fact quite different from N. veratrifolia by having glandular hair, much shorter inflorescence and flattened filaments.  As recently pointed out by de Vogel and G. Barretto (in Journ. Taiwan Museum 37: 78. 1984), the plants found in Hongkong, as well as those in Guangdong and Yunnan, possess glandular hair and short inflorescence. They are identical with the Vietnamese species N. balansae Gagnep., which was reduced by de Vogel to a synonym of N. zollingeri var singapureana. E. F. de Vogel's suggestion seems to be acceptable except the varietal rank.  It is treated here as a se- parate species, N. singapureana (Baker) Rolfe, according to its fruit and hair characters.  Thus we have altogether one species of Neuwiedia and three species of Apostasia in China, including a new species and a newly recorded one.

常山属的初步研究

Dichroa Lour., a small genus of Saxifragaceae, contains about 12 species, ranging from the mainland of S. E. Asia southward to Pacific islands. But most of the species are more restricted in distribution. Of the 12  recognized species,  six  are known from South China and Indochina; three are confined to west and northwest New Guinea; two are endemic to the Phillipines. Only one species is widely distributed in S. E. Asia.  In the present paper, the genus is divided into two sections  and two series based on the number of stamens and the characteristics of the ovary.  One spe- cies is described as new.
