- Title
Neotenic Evolution of a, Hummingbird-Pollinated Flower.
- Authors
Guerrant, Jr., Edward O.
- Abstract
The article focuses on the evolution of Delphinium nudicaule, a hummingbird-pollinated larkspur. It mentions that the paedomorphic character of the Delphinium nudicaule flowers may be a result of neoteny. It also stresses that the Delphinium nudicaule flowers show resemblance to the buds of Delphinium decorum rather than the flowers of the species. The vestigial lower petal blades of Delphinium nudicaule is stated to be the most distinguishing difference between the two species. It also stresses that in larkspurs pollinated by the bumblebees petal blades are large and serve as a landing pad for bumblebees. It also states that other floral differences including the nectariferous petals is not explained by neoteny.
