The evolution of flower morphology in Gentianaceae-swertiinae and the roles of key innovations and niche width for the diversification of Gentianella and Halenia in South America.

2003-09-01

Abstract excerpt

The circumscription of genera in Swertiinae (Gentianaceae-Gentianeae) was traditionally based on the presence of ovary or petal nectaries, variation of corolla tube length, level of stamen insertion, and presence and position of fimbriate appendages. Using a molecular phylogenetic framework, we found high homoplasy of these characters among and within the 14 genera of Swertiinae, and three of them (Gentianella, Lo...
