摘　　要：本文对绣球亚科全部９个属中选取４５个种或变种作了叶脉序的研究。绣球亚科除黄山梅属外，大体呈曲行羽状脉。叉叶蓝属，蛛网萼属和草绣球属同具真曲行羽状脉和相似的高级脉序；赤壁草属和冠盖藤属表现出明显的环结曲行羽状脉式样；钻地风属多呈现分支曲行羽状脉式样；常山属和绣球属包含多种过渡类型，与其它属密切相连。黄山梅属脉序为独特的羽状达缘型式样，明显表现出向掌状脉的过渡，与其它属不同。脉序研究支持Ｔａｋｈｔａｊａｎ系统把黄山梅属提升为亚科的处理，同时又表明从脉序性状来看，绣球亚科各属之间性状彼此重叠，没有十分明确的界限。In an attempt to help to elucidate relationships among the genera of Hydrangeoideae,leaf venation studies were conducted on representative species of 45 or variety of 9 genera. Except for the genus Kirengeshoma, leaf venation in Hydrangeoideae is basically camptodromous.Deinanthe, Plalycrater and Cardiandra are resemble by having the eucamptodromous venation and similar higher-order venation; Decunlaria and Pileostegia clearly show brochidodromous venation pattern, Schizophragma fundamentally show cladodromous venation pattern, Dichroa and Hydrangea appear as transitional groups and closely linked to other genera.Kirengeshoma differs from other genera by showing craspedodromous venation pattern andobviously shows the transition to actinodromous. It is suggested that the treatment of promotinggenus Kirengeshoma to subfamily Kirengeshomoideae by Takhtajan should be noted. The presentinvestication also indicate that generally, there is no clear cut discrimination of groups inHydrangeoideae and they overlap each other complexly.
