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。

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.

老子与《道德经》

老子以“道”为中心的哲学思想、“无为而治”的政治主张、“小国寡民”的社会理想、互相转化的朴素辩证法思想,在中国思想史上影响巨大,但他的辩证法思想是不彻底的,最终坠入了形而上学的泥坑。     

国产三角瓣花属(茜草科)订正

三角瓣花属Prismatomeris Thw．在Hooker(1873)和K．Schumann(1891)的茜草   科分类系统中隶于巴戟族Morindeae Miq．但在 Bremekamp(1966年)的分类系统中，其分类   位置未定。本属的胚根下位，花冠裂片镊合状排列和具针晶等特征与巴戟族相同，但它的花   离生，子房2室，胚珠盾形而着生于子房隔膜上半部等特征则与巴戟族明显不同。  因此，   将本属分立作族并置于Bremekamp所定界的茜草亚科Rubioideae中似乎较合适。  本文还提   供了经挑选的本属10对特征及其分类价值的说明。辨别了两个种：(1)将分布于中国的P.   tetrandra(Roxb．)K．Schum. 修订为 “P.tetrandra  (Roxb.)  K.  Schum. subsp. multiflora   (Ridley，)Y．Z．Ruan”. (2)P.  connata Y．  Z.  Ruan 被记述作新种它的热带新亚种是  P.  connata Y．  Z．  Ruan  subsp.  hainanensis Y．  Z．  Ruan。
