| 摘 要： | 本文借助光学显微镜和扫描电镜，对我国产鸢尾属Iris L．32种植物的花粉形态进行
了观察。该属植物的花粉为舟形或近球形。萌发孔可分为远极单沟、远极单沟-拟沟、二合
沟及无萌发孔等类型。外壁主要为网状纹饰，少数具瘤状或鼓槌状纹饰。本文依据花粉形态 和其它器官特征，对本属花粉外壁及萌发孔的演化趋势及某些种的分类地位进行了探讨。

| Abstract: | In this paper, pollen grains of 32 species of the genus Iris in China were ex-
amined under light microscope and scanning elrctron microscope. Pollen grains in Iris of
China are navicular or subspheroidal. According to the characters of aperture and shape,
pollen grains may be divided into four types: (1) Monocolpate (distal): pollen grains navicu-
lar or subspheroidal, exine reticulate. (2) Monocolpate-colpoidal: pollen grains subspheroid-
al, exine pilate. (3) 2-syncolpate: polen grains subspheroidal or navicular, exine reticulate.
(4) No aperture: pollen grains subspheroidal; exine verrucate.
The evolutional trends of aperture and exine ornamentation are traced and systematic po-sitions of some species are discussed based on characteristics of pollen grains and other organs. |
