摘要:

利用扫描电镜对天南星科Araceae22属28种(除Arum maculatum产自德国外,其余均产自中国)
及菖蒲科Acoraceae 1属2种植物的花粉形态进行了观察。结果显示天南星科花粉形态在科内变异很
大。花粉粒形状从球形、近球形、椭球形到扁球形和橄榄形;萌发孔类型有散孔型、具薄壁区型、环沟型
或无萌发孔;外壁纹饰为小穴状、网状、肋条状、条纹状、疣状、具刺或光滑。主要依据花粉形态方面的证
据探讨了崖角藤属Rhaphidophora、麒麟叶属Epipremnam 、龟背竹属Monstera 3属的属间关系以及犁头尖
属Typhonium属下分类中存在的一些问题。

Abstract:

 Pollen morphology in 28 species of 22 genera in the Araceae and two species in the Ac-
oraceae, all from China except Arum maculatum, has been investigated under scanning electron mi-
croscope. Pollen grains in the Araceae are morphologically highly variable among the genera. They
are spherical, subspherical, ellipsoidal, oblate or olive-shaped in shape. The apertures are panto-
porate, tenuate, zonate or inaperturate. The exine ornamentation is foveolate, reticulate, ribbed,
striate, verrucate, echinate or psilate. Based on the results, some taxonomic problems in the Arace-
ae, particularly the intergeneric relationships among Rhaphidophora, Epiprermnum and Monstera,
and the infrageneric classification within Typhonium, are discussed. Palynological data seem to sup-
port the treatment of Rhaphidophora, Epipremnum and Monstera as three independent genera.
