The diversification of Halenia (Gentianaceae): ecological opportunity versus key innovation.

Evolution; international journal of organic evolution - 1 Nov 2003

von Hagen K B, Kadereit J W

Abstract excerpt

The plant genus Halenia (Gentianaceae) consists of herbs growing in temperate and tropical alpine habitats and most species possess flowers in which nectar is produced in spurs. This probably helps reward only specialized long-tongued pollinators, and a narrow pollinator/flower relationship is thought to accelerate diversification rates (a key innovation). To test the pattern of diversification of Halenia against...
