StandleySpecies Cosmocalyx spectabilis
Cosmocalyx is a genus of flowering plants in the family Rubiaceae. It has only one species, Cosmocalyx spectabilis.[1] It is rare, and endemic to the Mexican states of Quintana Roo and Yucatán.[2]
Cosmocalyx was named by Paul Standley in 1930.[3][4] The generic name is derived from the Ancient Greek words, kosmos, meaning "beautiful", and kalyx, "a calyx".[5]
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]
Cosmocalyx is placed with Deppea, Hoffmannia, Hamelia and several other genera in the tribe Hamelieae.[6] Relationships within this tribe are uncertain.
