Ekmanianthe actinophylla

Ekmanianthe is a genus of flowering plants in the family Bignoniaceae endemic to the Greater Antilles. It is most closely related to Tabebuia and has sometimes been included within it.

Taxonomy

Both species of Ekmanianthe were originally described in 1866 by August Grisebach, who placed them in the genus Tecoma. In 1915, Nathaniel Lord Britton placed them in Tabebuia. In 1924, Ignatz Urban, recognizing their distinctiveness, erected the new genus Ekmanianthe in the journal now known as Feddes Repertorium, which was at that time edited by Friedrich Karl Georg Fedde. Ekmanianthe was named for the Swedish botanist Erik Leonard Ekman (1883-1931)."Anthe" is derived from a Greek word for "flower".

Species

It consists of two species of trees, both of which are considered Endangered by the IUCN Red List:

Evolution

The evolution of Ekmanianthe is in some ways parallel to that of the Asian tribe Oroxyleae. The bat-pollinated Oroxylum has actinomorphic flowers with five fertile stamens. The hawkmoth-pollinated Nyctocalos has elongate flowers and most of the species have only four fertile stamens.

Description

The following description is based on two sources.

Ekmanianthe actinophylla is chiropterophilous (bat-pollinated). E. longiflora has the long, narrow corolla tube that is typical of hawkmoth-pollinated flowers.

The basally curved fruit of Ekmanianthe is a distinguishing feature, clearly separating that genus from Tabebuia. The edge of the corolla is laciniate in a few moth-pollinated and a few bat-pollinated species of Tabebuia, but much less so than in Ekmanianthe. The lenticels of E. longiflora and the costae (ribs) on the fruit of E. actinophylla are more prominent than those of any species of Tabebuia. The corolla tube of E. longiflora is longer than that of any species of Tabebuia. E. actinophylla has 5 fertile stamens, a trait not seen in Tabebuia.

The wood of Ekmanianthe has been variously described as "soft" or as "very hard, heavy, and strong". Despite this, like many other Tecomeae species, it is rarely cultivated.
