Abstract

Cleomaceae is a family that includes 18 genera distributed worldwide in tropical and temperate regions. Cleome L. is the largest genus having 207 species, widely distributed in tropical and subtropical regions (POWO 2019). In Vietnam, the genus is represented by four species Cleome rutidosperma DC., C. houtteanaSchltdl., C. viscosaL. and C. gynandraL. The present study documents the pollen and seed characteristics of all four species of Cleome in Vietnam, and the data obtained using light microscope and scanning electron microscope are analyzed considering their importance in taxonomic delimitation and understanding their phylogenetic relationship. The results indicated a close relationship between different pollen and aperture types. The striking differences between the pollen shapes among different species of Cleome could be useful in taxonomic and evolutionary studies. Similarly, seed shape and surface characters provided important clues for their delimitation. Based on the pollen and seed morphological characteristics, a taxonomic key has been provided for easy identification of the Cleome species in Vietnam.

标题越南Cleomaceae植物的花粉和种子形态

铁线蕨科包括18个属，分布在世界各地的热带和温带地区。Cleome L.是最大的属，有207种，广泛分布于热带和亚热带地区(POWO 2019)。在越南，该属有4个种为代表的Cleome rutidosperma DC。， c.h outteanaschl .;C.粘性;C. gyynandral。本文记录了越南所有四种克莱米属植物的花粉和种子特征，并利用光镜和扫描电镜对所获得的资料进行了分析，考虑到它们在分类划界和了解它们的系统发育关系方面的重要性。结果表明，不同花粉类型与孔型之间关系密切。不同种花粉形态的显著差异可用于分类学和进化研究。同样，种子的形状和表面特征也为其划分提供了重要线索。根据花粉和种子的形态特征，提供了一个易于鉴定的分类钥匙。
