摘要
长蕊木兰(Alcimandra cathcartii)花粉粒椭圆形,具远极单萌发沟,外壁雕纹小穴状。外壁覆盖层具穿孔,柱状层有不典型的小柱,内壁可明显地分为3层。
The pollen grains of Alcimandra cathcartii (Chun et Tsoong)Law are bilateral symmetric, heteropo-lar,monocolpate broadly elliptica in polar view,boat-shaped in equatorial view. Exine is foveolate. Ultrastruc-ture of pollen wall shows that both the exine and the inline can be distinguished clearly into 3 layers. The tec-tum is smooth and perforate,untypical columelae are found in the bacula.
