中国伞形科八个属的花粉形态研究

本文对我国伞形科8属22种和1变种的花粉,除用光学显微镜进行了系统 的观察外,并用扫描电子显微镜观察了它们外壁的细微结构,在综合分析对比的基础上,论证了花粉形态研究在伞形科分属水平上的意义。     

前胡族花粉外壁超微结构及其系统学意义(英文)

Transmission electron microscopy (TEM) observation of pollen grains of 18 species belongingto 18 respective genera of the tribe Peucedaneae Drude revealed distinct ultrastructural difference in thepollen exine, including the thickness and features of rectum, columnar layer, foot layer and endexine. Thesystematic position of those 18 species are re-evaluated based on their ultrastructural characteristics ofpollen exine observed in this study. Seven genera related to Angelica L. in Angelicinae Drude have beendeduced to genus Angelica L. For example, Osterfcum grosseserratum (Maxim.) Kitagawa was changed toAngelica L. by some authors, but it differs from Angelica sinensis (Oliv.) Diels in having well developedtectum which is thicker than the columnar layer and foot layer. Its columnar layer is quite well-developedwith long and branched columellae. Besides its surface is tuberculated. Evidently, its development exceedsthat of Angelica sinensis. However, it is only a moderate evolutional species in its genus, and the Angelicasinensis accounts as the most advanced species in Angelica Diels, thus, placing genus Ostencum Hoffm.in Angelica L is not suitable, it may be more appropriate to keep its original position. In addition, Ferulaakitschkensis B. Fedtsch. ex K.-Pol. differs greatly from those of Talassia transiliensis (Herd.) Korov. andSchumannia turcomnnia Kuntze, because of its very well-developed columnar layer, being about four tofive times thicker than the total of tectum and foot layer, tuberculated tectum surface and complicatedstructure of columnellae. As another species Heracleum forrestJ‘iWolff also differs from Semenovia rubtzovii(Schischk.) Monden. in having an even thickness of exine and well-developed columnar layer, it seemssuitable that they should also be treated as two independent genera.     

中国伞形科两新种

本文记载了产于我国云南的亮蛇床属植物新种长萼亮蛇床和四川前胡属新种木里前胡。     

弓翅芹属——伞形一科新属

复伞形花序分枝极多,侧伞形花序长度往往超过中央主伞形花序,组成为许多总状花丛,无总苞片和小总苞片,有时偶有1总苞片,但为膜质,脱落性;伞辐少数,纤细,极不等长,十分开展;每小伞形花序具少数花,花柄不等长,丝线形;花细小,花瓣白色,长卵形,基部具爪;花柱短粗,花柱基圆锥形,细小;萼齿显著,花粉粒为长球形。     

高分辨裂解—气相色谱在前胡族系统分类中的应用

采用高分辨裂解－气相色谱法对前胡族（Peucedaneae Drude)20属35种植物的叶片成分进行分析,经过聚类分析得出以下结果：35种植物基本可分为3大类,对应于3个亚族。阿魏亚族（Ferulinae Drude)的球根阿魏属（Schumannia Kuntze)、伊犁芹属（Talassia Korov.)和簇花芹属（Soranthus Ledeb.)均应为独立属。环翅芹亚族（Tordyliinae Drude)的四带芹属[Tetrataenium(DC.)Manden.]和大瓣芹属（Semenovia Regel et Herd.)二者也作为独立属处理为宜,其中有争议的锐尖叶独活[Heracleum longilobum(Norman)Sheh et T.S.Wang]不应作为大瓣芹属成员,仍应保留于独活属。当归亚族（Angelicinae Drude)的山芎[Conioselinum chinense(L.)Britton]和东当归[Angelica acutiloba(Sieb.et Zucc.)Kitagawa]曾被作为阿米芹族（Ammineae Koch)的蛇床属（Cnidium Cuss.)或藁本属（Ligusticum L.)的成员,聚类图显示其属于前胡族的当归亚族是合适的。
