马先蒿（Scrophulariaccae）代表了授粉生物学家花卉形态多样性的经典例子。在喜马拉雅山物种丰富的地区，很少有关于马先蒿授粉综合症的研究，特别是长管物种。 2000年夏秋两季，在滇西北中甸地区对四种马先蒿的授粉生物学进行了研究。这四种熊蜂以三种熊蜂为食，拥有两种不同的花冠类型：黄马先蒿 (Pedillaryis lutescens Franch)。前马克西姆。亚种lutescens 和 P densispica Franch。前马克西姆。花冠类型为短管、有雄花和授蜜，仅由 Bombus friseanus Skorikov 和 B. lucorum Latr 授粉。工蚁采集花蜜并为 N P. integrifolia Hook 授粉。 I. 和 P 三色 Hand.-Mazz。具有长管状、喙状、无花蜜的花冠，由 Bombus festivus Smith 和 B. friseanus 工蜂通过胸骨授粉，将油悬挂在 S 形喙上或由锉碗形下唇支撑。熊蜂工蜂的异花授粉是在云南观察到的马先蒿最重要的繁殖机制。没有发现采花蜜的熊蜂（蜂王和鳞翅目飞蛾或蝴蝶）为任何这些马先蒿物种授粉。除此之外，云南西北部的马先蒿和熊蜂之间的相互作用以及授粉机制与日本和北美相似。本研究提供了新的证据，表明日本物种大厅是从喜马拉雅迁徙者进化而来的，其模式与北美物种相似。
Pedicularis 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.
