Nashia

Description

Nashia is a genus of flowering plants in the vervain family, Verbenaceae. Until recently, there were 7 known species to exist within the genus Nashia .  However, the seven species placed in the genus Nashia were revised, based on the totality of the (scant) material found in the world's herbaria. A morphological analysis of, in particular, the calyx and fruit reveals the heterogeneity of the genus. As a result, Nashia was reduced to its single original species, N. inaquensis , described from Great Inagua, Bahamas (where it is considered to have been introduced), and recently found in Puerto Rico and the Virgin Islands (St. Croix). N. Spinifera , of Hispaniola, was placed in the genus Isidroa, to monotypic new genus. The five Cuban endemics, plus two newly described here, make up the new genus Diphyllocalyx , formerly Lippia sect. Diphllocalyx of Grisebach.
