AbstractPedicularis L (Scrophulariaccae) represents a classic example of floral morphological diversity for pollination biologists. In the species-rich areas of the Himalayas there have been few studies oil the pollination syndromes of Pedicularis, especially of the long-tubed species. In the summer and fall of 2000, the pollination biology Of four species of Pedicularis was studied in Zhongdian of northwestern Yunnan, China. The four species, foraged In three bumblebee species, possess two different corolla types: Pedicularis lutescens Franch. ex Maxim. subsp. lutescens and P densispica Franch. ex Maxim. have a short-tubed, erostrate, and nectariferous corolla type and are pollinated exclusively by Bombus friseanus Skorikov and B. lucorum Latr. workers foraging flower nectar and pollinating nototribically N P. integrifolia Hook. I. and P tricolor Hand.-Mazz. have long-tubed, rostrate, and nectarless corollas and are pollinated sternotribically by Bombus festivus Smith and B. friseanus workers hanging oil the S-shaped beak or supported by file bowl-shaped lower lips. Cross-pollination by bumblebee workers is the most important reproductive mechanism observed for these Pedicularis in Yunnan. Nectar-foraging bumblebee (queens and lepidopteran moths or butterflies were not found to pollinate any of these Pedicularis species. Otherwise, the interactions between Pedicularis and Bombus and Pollination mechanisms in northwestern Yunnan are similar to those in Japan and North America. The present study provides new evidence that the Japanese species hall evolved from Himalayan Migrants in a pattern parallel to that of North American species.
