Abstract
It has been accepted that the evolution of long‐tubed flowers is driven by long‐tongued pollinators. However, numerous Pedicularis species in Himalayas evolve long corolla tubes but are pollinated by bumblebees. As shown on the cover that corolla tubes in P. siphonantha from southwest China are up to 10 cm in length. Huang et al. (pp. 698–700) manipulated the length of the corolla tube to examine pollinator preference and seed set, data obtained do not support the traditional hypothesis. Photo provided by Shuang‐Quan Huang.
