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.     

蕊生低语

山月笛声 这时有人吹横笛,直吹得溪山月色与屋瓦变成笛声,而笛声亦即是溪山月色屋瓦,那嘹亮悠扬,把一切都打开了,连不是思心徘徊,而是天上地下,星辰人物皆正经起来,本色起来了,而天下世界古往今来,就如同“银汉无声转玉盘”,没有生死成毁,亦没有英雄圣贤,此时若有恩爱夫妻,亦只能相敬如宾.

《红楼梦》中藕官-蕊官性脚本的解构意义

曹雪芹在《红楼梦》第58回“杏子阴假凤泣虚凰，茜纱窗真性揆痴理”中描绘了藕官－蕊官的女性同性恋情状，从中体现了对清代社会父权统治的有限的解构意义。

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。     

关于露蕊乌头系统位置的植化资料

从露蕊乌头全草中分离及鉴定出4种二萜生物碱：  talatizamine, 14-acetyltalatizamine，condelphine 及 isotalatizamine。根据现有的植化资料，其系统位置似更接近于林地乌头及塔拉斯乌头。
