Abstract

The reproductive biology and ecology of five non-hybridizing, sympatric species of Aneilema in Kenya is investigated. The high number of species at the study site is believed to be due to the ecological diversity at this locality. Differences in ecology and seasonal flowering periods appear to be inadequate to reproductively isolate these species. However, differences in daily flowering times, pollinators, floral morphology and opening behaviour, and in chromosome number, alone or in combination (perhaps also coacting with other factors not fully evaluated), are effective isolating mechanisms.
