摘要：distinguished from its allied genera by a number of characteristics:
(1) the stamenswith their filaments coherent into a central column;
(2) the female flowers possessingrudimentary stamens;
(3) the ovary 3-celled, with one ovule in each cell;
(4) the fruitsdehiscent, 3-rostrated at the apex;
(5) the fruits possessing persistent perianth;
(6)the seeds tuberculate and winged. However, upon a careful comparison of Trirostell-um yixingensis Z.P. Wang et Q. Z. Xie, the type species of Trirostellum with Gyno-stemma pentaphyllum (Thunb.) Mak., the type species of Gynostemma Bl. and someother species of Gynostemma as well,we have found that the representatives of theabove two genera are identical in most of the important diagnostic characteristics ex-cept that the fruits of the former genus are dehiscent with three long beaks at theapex, while the fruits of the latter genus are indehiscent with very short beaks.
Besides, results obtained from chromosome counting haove shown that the somaticchromosome number of Trirostellum yixingensis is 2n=22, while that of Gynostemmapentaphyllum is 2n=28.
Yet these morphological and chromosomal differences seemnot sufficient for generic demarcation. We, therefore, suggest that Trirostellum bereduced to a sectional or subgeneric rank of Gynostemma Bl。
