Hexisea Lindl.

Flora Data (Last Modified On 11/13/2012)

Genus	HEXISEA Lindl.
PlaceOfPublication	Hook. Jour. Bot. 1:7. 1834.
Synonym	Euthonaea Reichb. f. in Bot. Zeit. 10:772. 1852.
Description	Caespitose epiphytic herbs. Stems simple or branched, terete or angled, seg- mented, thickened or pseudobulbous. Leaves few, usually one or two from the apex of each segment, usually deciduous annually. Inflorescence from the apex of the growths, few-flowered, short; flowers small but highly colored. Sepals similar, erect or spreading, narrow, the laterals often shortly connate at the base. Petals similar to the sepals. Lip simple or lobulate, adnate at the base with the column, base of the lamina geniculate and usually callus-thickened. Column short, adnate to the lip below the middle; clinandrium 3-lobed; anther operculate, incumbent; pollinia 4, collateral, waxy.
Note	About a half dozen species in Central and South America. Living material should prove instructive as to the origin of the inflorescence and new growth, for both apparently come from the apex of the preceding growth, which is somewhat unusual. The monotypic genus Alenwnia Llave & Lex. (The only one of the Llave & Lexarza orchids for which a type is known to exist) should possibly include Hexisea. Florally they are not to be distinguished but the vegetative growth may keep them separate until more is known about them.
