Pollination of a slippery lady slipper orchid in south-west China: Cypripedium guttatum (Orchidaceae)

Cypripedium guttatum was studied in north-west Yunnan at 3490 m a.s.l. The flowers are rewardless 'kettle traps'. The structure of the lip, where pollinators are temporarily kept prisoner, and the method of their capture, are unusual in being Paphiopedilum- rather than Cypripedium-like. Th...
