Trees or shrubs, with pale quadrangular branchlets and minute acuminate buds. 

 Leaves opposite, short-petiolate, oblong-obovate, -rounded and sometimes emarginate 

 at the apex, entire or remotely crenulate-serrate above the middle, with revolute 

 thickened margins, feather-veined, coriaceous, persistent; stipules minute, acuminate, 

 membranaceous, caducous. Flowers unisexual, pedicellate, in axillary pedunculate 

 few-flowered dichotomously branched cymes bibracteolate at the apex ; calyx minute, 

 4-lobed, persistent, with a short urceolate tube and rounded lobes; disk fleshy, fill- 

 ing the tube of the calyx, cup-shaped, slightly 4-lobed; petals entire, obovate, white,

 black or dark blue, oval or obovate, crowned with the remnants of the persistent 

 stigma, often 1-celled by abortion; flesh thin; stone thick, crustaceous. Seed oblong, 

 suspended; seed-coat membranaceous; albumen thin, fleshy; embryo axile; cotyle- 

 dons ovate, foliaceous; radicle superior, next the hilum. 



Gyminda with a single species is distributed from southern Florida to Trinidad 

 and southern Mexico, and is represented in Central America by what is perhaps a 

 second species. 



The generic name Is formed by transposing the first three letters of Myginda, to 

 which this plant had been referred.
