开口箭属一新种及其核型和花粉形态

文章报道了新种屏边开口箭T．pingbianensis J．L．Huang et X．Z．Liu及其核型和花粉形态。屏边开口箭的核型公式为2n=38=14m+lOsm+8st+6t,具明显的二型性,属3C型。花粉粒为球形,无萌发孔沟,外壁具皱块状纹饰。从花结构、核型和花粉形态上看,屏边开口箭和伞柱开口箭T．fungilliformis Wang et Liang亲缘关系近,而且伞柱开口箭比屏边开口箭在一系列特征上都较特化。     

A New species of the Genus Tupistra (Convallariaceae), with Reference to Its Karyotype and Pollen Morphology

A species of the genus Tupistra,T．pingbianensis J．L．Huang et X．Z．Liu,is described as new,and its karyotype and pollen morphology are reported． The bimodal karyotype of this species is formulated as 2n＝38＝14m+10sm+8st+6t,and pollen grains are spheroidal,inaperturate,with rugulate exine sculpture．Based on its floral structure,karyotype and pollen morphology,T．pingbianensis J．L．Huang et X．Z．Liu is considered phylogenetically closely related to T．fungilliformis Wang et Liang．Whether the repense rhizome,solitary leaves of T．pingbianensis J．L．Huang et X．Z．Liu indicate a close relationship between the genus Tupistra and the genus Aspidistra needs further studies．     

Eudesmanolides,guaianolides, germacranolides and elemanolides from Zinnia species

The investigation of six Zinnia species afforded in addition to already known compounds two eudesmanolides, five guaianolides, three germacranolides, five elemanolides and a dihydroxygeranylgeraniol. The structures were elucidated by spectroscopic methods and some chemical transformations. The chemotaxonomic situation is discussed briefly.     

杏属（蔷薇科）一新种

发表了蔷薇科杏属的一个新种,即仙居杏(Armeniaca Xianjuxing J.Y.Zhang et Z.X.Wu),其与普通杏(Armeniaca vulgaris Lam.)的区别在于叶片两面具有短柔毛,花梗或果梗长1~1.2 cm,花瓣边缘钝锯齿或小裂片状,萼片边缘有小钝锯齿。     

Alkaloids and other constituents of Zanthoxylum williamsii,Z. monophyllum and Z. fagara

Zanthoxylum williamsii (Rutaceae) was found to contain (+)-asaranin, (+)-sesamin, esculetin dimethyl ether, nitidine, chelerythrine, magnoflorine, laurifoline, skimmianine and edulinine. The quaternary alkaloid fraction of Z. monophyllum contained berberine, magnoflorine, chelerythrine and a 1,2,9,10-substituted dihydroxydimethoxy-N,N-dimethylaporphinium salt. Leaves of Z. fagara were found to contain synephrine. Leaves of each species were examined for the presence of bishordeninyl terpene alkaloids, but none was found. Some chemotaxonomic relationships among Zanthoxylum species are discussed.

大兴安岭的黄梅属地衣

本文报导了分布在大兴安岭的10种黄梅属(Xanthoparmelia)地衣,很多文献曾报导过中国的菊叶黄梅(X.conspersa),但是魏江春(1983)根据形态及化学两方面研究的结果指出,文献中的菊叶黄梅实际上分别是暗腹黄梅(X.tinctina)和淡腹黄梅(X.mexicana)。本文作者在大兴安岭北部釆到了真正的菊叶黄梅。本文还包括5个中国新记录种,它们是贴生黄梅(X.hypopsila),线形黄梅(X.lineola),新墨西哥黄梅(X.novomexicana),黑黄梅(X.tasmanica)和离心黄梅(X.centrifuga)。     

中国黄梅属地衣的初步订正

本文是作者对中国黄梅属地衣从形态与化学两方面进行比较研究之后的初步订正。研究结果表明,文献中所记载的中国 Parmelia conspersa Ach. 实际上为Xanthoparmeliatinctina(Mah.et Gillet)Hale及X.mexicana (Gyeln.)Hale的误用名称;长白山的Parmeliasubramigera Gyeln. 则为X. mexicana的误用名;Parmelia stenophylla(Ach.)Heug.及Parmeliasubconspersa Nyl为X. taractica(Krempb.)Hale的误用名;Parmelia vagans (Nyl.)Nyl.为X.camtschadalis(Ach.)Hale的误用名。此外,文中还报道了新组合一种,新变种一个,中国新记录一种。
