A
New Species of Cyanotis (Commelinaceae) from Africa The
genus Cyanotis (No common name) is a member of the plant family
Commelinaceae, which includes the spiderworts and dayflowers. There
are about 50 species of Cyanotis located mainly in the Old
World. Members of the genus exhibit a wide array of characteristics.
Cyanotis is characterized by succulent leaves that have great
water storage capacity and by small, usually blue to violet flowers
with fused petals and six deeply bearded stamens. Species of Cyanotis
occur mainly in dry habitats, but a few grow in forests or are aquatic.
For this research living plant material was obtained from the Smithsonian
Institution Botany Research Greenhouse and dried material along with
liquid preserved material was examined from the United States National
Herbarium. Comparative morphology and anatomy was studied on the specimens
of three related species from eastern Africa and the Arabian Peninsula.
One of them was confirmed as a new species with two geographically
separate subspecies. This species is described for the first time.
Conservation of species can only be done when the species themselves
and their variation and distribution are understood. Basic studies
of species, using traditional methods, provide that information. This research was supported by a grant from the National Science Foundation Research Experiences for Undergraduates program, Award Number DBI 9820303. |
