Abstract
Most of the mentioned species-rich, hummingbird-pollinated plant clades have the highest species numbers, including many endemics, in the topographically highly structured (sub-)tropical mountain ranges that provide a number of different habitat types close to each other (e.g., Lagomarsino et al., 2016). If the ability for long-distance dispersal is missing, such as in many North American lineages of hummingbird-pollinated plants, for example, in hummingbird-pollinated clades of I Penstemon i , I Silene i (Caryophyllaceae), or I Monarda i (Lamiaceae), then these clades are rarely species-rich. Hummingbird pollination evolved numerous times independently and has been reported from 404 plant genera distributed over 68 angiosperm families (Abrahamczyk and Kessler, 2015). Why are some hummingbird-pollinated plant clades so species-rich?. [Extracted from the article]
