摘要
系统观察了福建薯蓣属 1 4种植物的叶脉特征 .根据脉序差异可分为两种类型 ,即羽状脉、弧形脉 ,由于各种间在一级脉的数目、方式、二级脉的夹角、走向、三级脉的类型、网眼发育情况、叶缘末级脉序类型以及盲脉分支情况等方面 ,存在种间差异 ,且形状稳定 .
Conducts the systematic observation on leaf venational patterns of1 general and1 4 species of Chinese yam in Fujian. Based on their different characteristics,the Chinese yam leaf vena- tions are divided into two tyte:eclosion and curve.These species venational characteristics distinct from each other in a number of primary vein,ramified,the secondary veins' angle of divergence and behaviour,the third veins' tyte,mesh grow stste of affairs and the venations type of the leaf edge. And these distinctive characteristics are sterdy,which indicate thatthe leaf venational of Chinese yam have significance for the delimitation of species.
