摘要
在米纳斯吉拉斯州的viaperosa，记录了7种Oxypetalum的访花者。阑尾石斛、banksii亚种、banksii、alpinumn var. alpinum和pachyglossum均由胡蜂传粉，这四种植物的传粉媒介是小蜂。在花形态非常相似的两种植物中，P ignobilis主要促进O. alpinum var. alpinum和O. pachyglossum的种间传粉。O. jacobinae、O. mexiae和O. subriparium由蜜蜂授粉。黄蜂和蜜蜂的口器携带一种、两种、三种或几种传粉花粉。O. mexiae是viosa的一种特有种，由于其花很少被访问，因此似乎表现出生殖限制。
Pollinators of Oxypetalum (Asclepiadaceae) in southeastern Brazil.
Floral visitors of seven species of Oxypetalum were registered in Viçosa, State of Minas Gerais. O. appendiculatum, O. banksii subsp, banksii, O. alpinumn var. alpinum and O. pachyglossum are pollinated by wasps, being Polybia ignobilis (Vespidae) a pollinator of these four species. It seems that P ignobilis promotes interspecific pollinations mainly between O. alpinum var. alpinum and O. pachyglossum, two species with very similar floral morphology. O. jacobinae, O. mexiae and O. subriparium are pollinated by bees. Wasps and bees carry one, two, three or several pollinaria in the mouthparts. O. mexiae, an endemic species in Viçosa, seems to present reproductive limitations, since its flowers are seldom visited.
