Venation Pattern of Syndiclis Hook. f. and Its Related Genera
油果樟属和近缘属的网脉结构式样

Minor venation patterns of Syndiclis, Beilschmiedia, Potameia, Sinopora, and Endiandra were observed. The results showed that their venation patterns could be grouped into three types, the Type A with fine leaf reticulations bearing no free ending of veinlets, the Type B with fine leaf reticulations having free and simple ending of veinlets, and the Type C with coarse leaf reticulations possessing profusely branched ending of veinlets. Beilschmiedia was provided with the most diversified venation including all 3 types while other genera had only one of the 3 types each. Syndiclis, Sinopora, and the Chinese Endiandra shared the Type A venation pattern which was different from Potameia with the Type C venation pattern.
