Cosmocalyx spectabilis |
Cosmocalyx is a monotypic genus of flowering plants in the family Rubiaceae. The genus contains only one species, viz. Cosmocalyx spectabilis, which is found in Mexico, Belize, and Guatemala.[1]
Description
Cosmocalyx spectabilis is a slender tree, up to 15 m (49 ft) in height and 20 cm (7.9 in) in diameter (dbh). After anthesis, one of the four calyx lobes expands into a reddish, leaf-like structure called a calycophyll. These facilitate dispersal of the fruit by wind. The fruit is a cylindrical indehiscent bilocular capsule. Each locule contains one basally inserted seed. This combination of characters distinguishes Cosmocalyx from other genera in Rubiaceae.[2]
