广西被子植物二新记录属

在第四次中药资源普查中采集了大量标本，经过对这些标本进行仔细鉴定并查阅相关资料，确定其中两号标本为香茜属(Carlemannia Benth.)和粘腺果属(Commicarpus Standl.)植物。这两属植物在广西尚无报道，为首次记录。香茜属植物叶对生，子房下位，无托叶，雄蕊仅有2枚，这和茜草科相似但又不同，系统位置较混乱，以前曾放于茜草科( Rubiaceae)和忍冬科( Caprifoliaceae)中，最近该属和蜘蛛花属独立成香茜科( Car-lemanniaceae)。该属植物共有3种，沿喜马拉雅山脉向东一直分布到缅甸、越南北部。我国西藏东南、云南南部、广西西北部分布一种即香茜( Carlenannia chinenesis Hook. f.)。粘腺果属是紫茉莉科( Nyctaginaceae)主产热带地区的1个属，全世界约25种分布于热带非洲和阿拉伯半岛南部，在南亚、东南亚和墨西哥至热带美洲也有少量分布。中国产2种，其中广西产1种即中华粘腺果 Commiaicarpus chinensis ( L.) Heim.]。该种植物分布广泛，从南亚次大陆向东至中南半岛、马来半岛，向北到我国西沙群岛、海南岛以及广州附近，在广西首次记录，产凤山县和凌云县。

Two newly recorded genera of angiosperm from Guangxi

In the Pilot Work of the Fourth National Survey on Chinese Materia Medica Resources, we collected many herbarium specimens. Through detailed identified and consulted literatures, we identified that there were two new recourded genera of Guangxi in these specimens. The genus Carlemannia Benth., leaf opposite, ovary inferior, estipulate, stamens only two, similar to Rubiaceae, but there were significant differences. Therefore, it was previously putted in Rubiaceae and Caprifoliaceae, most recently this genus with Silvianthus form a new family Carlemanniaceae, only three spicies in this genus. This family distributed along the Himalayas to Burma, North Vietnam and South China, one species Carlenannia chinenesis Hook. f. in Southeast Tibet, South Yunnan, Northwest Guangxi. Commicarpus is a genus producing in the areas of tropical, about 25 specieses in the world, main in tropical southern area of Africa and the Arabian Peninsula, in South Asia, Southeast Asia and Mexico to tropical America also has some specieses. Two specieses distributed in China, only Commiaicarpus chinensis(L.)Heim. in Guangxi. This species is distributed from the South Asian subcontinent east to Indochina, Malay Peninsula, and north to the Xisha Islands, Hainan Island, and the nearby Guangzhou of China. It is firstly recorded in Guangxi Fengshan and Lingyun counties.
