Description
The floral biology of Tricyrtis macropoda was investigated and compared with that of a closely related species T. affinis. Many features of the pollination system are similar in the two species : for instance, flowers are protandrous and self-compatible ; they last for two days ; and the main pollinator is Bombus diversus diversus. The perianth of Tricyrtis macropoda, however, is turned down at a point 1 / 3 of the way up from the base in contrast to that of T. affinis, whose perianth is horizontally patent at the same level. In Tricyrtis macropoda the bumblebee alights on the steep perianth and then climbs up to its ridge to suck nectar ; this behavior is rather different from its placid behavior in the flower of T. affinis. The flower of Tricyrtis macropoda has no apparent nectar guides in the basal part of the perianth. A reason for and an evolutionary trend leading to the lack of the nectar guide is discussed.
