伞形科参棕亚科及牵环花亚科气孔的结构及其分类学价值
Stomatal structures of the Apiaceae subfamilies Mackinlayoideae and Azorelloideae and their taxonomic value
摘要
Abstract
The stomatal structures of the leaves (stems or fruits)of 48 species representing 34 genera of the Apiaceae subfamilies Mackinlayoideae (9 genera)and Azorelloideae (21 genera)and their relative taxa were studied in detail for the first time.Three types of stomata - anomocytic,anisocytic and paracytic - were ob-served.In Mackinlayoideae,the stomata are mostly paracytic and the minority are anomocytic.In Azorel-loideae,stomata are mostly anomocytic and the minority are anisocytic.Cell walls in the Bowlesia clade are deeply waved while they are usually straight in the other clades of Azorelloideae.This stomatal study provides morphological evidence for the two subfamilies and the Bowlesia clade that have been established by molecular research.It also provides evidence to support moving Apiopetalum,Mackinlaya and Stilbocarpa from Arali-aceae to Mackinlayoideae and Azorelloideae,and against placing Homalosciadium,Platysace ,Hermas and Klotzschia in either of these subfamilies.关键词
