Key to the genus Penstemon and its related genera in the tribe Cheloneae (Scrophulariaceae).
The potential of campanulate flowers for adaptation to different pollinators is exemplified by the genus Penstemon (Cheloneae), which, in addition to various bees (honey, carpenter, bumble, and solitary bees), is pollinated by hummingbirds, coleopterans, masarid wasps, bee flies, syrphid flies, moths and other lepidopterans, dipterans, and hymenopterans (Schmid, 1976).
He knows of 15 members of the genus Penstemon that rely on hummingbirds and may have evolved this reliance independently of one another.
