摘要:

 四合木属Tetraena Maxim.   是内蒙古自治区西部和亚洲中部荒漠区东部的特有属,也是珍稀
  濒危植物。前人曾对该属的系统地位做过一些研究,但观点不一。作者通过对该属的研究历史、雌蕊、
  果实、花粉粒、染色体等的综合研究后,建议将该属从TaxTaЛЖЯН系统(1987)蒺藜科的霸王亚科中分
  出,成立一个新亚科——四合木亚科。本文还编写了蒺藜科(狭义的)分亚科检索表。  四合木属的系统
  地位是:芸香目蒺藜科四合木亚科四合木属。

关键词: 四合木属, 花粉粒, 染色体, 系统地位, 四合木亚科

Abstract:

Tetraena Maxim.  is an endemic genus of Inner Mongolia and the desert region
of Central Asia. It is also a rare and endangered plant. Some botanists had made some research
on the systematic positions of this genus, but their views are debatable. Through a comprehensive
study: research history, morphology (pistil, fruit), pollen grains, chromosomes, the authors sug-
gest that this genus be separated from Zygophylloideae (Zygophyllaceae, Takhtajan. 1987) and
a new subfamily-Tetraenoideae be set up for it.  A  key to subfamilies of  Zygophyllaceae
(sen. str.) is provided. The systematic position of Tetraena Maxim. is: Rutales-Zygophyllaceae
-Tetraenoideae-Tetraena.
