(in honor of Desmazieres, a French botanist). Gramineae. Plants resembling Eragrostis, sometimes grown as ornamental grasses.

Spikelets many-fid., strongly compressed, the lemmas keeled and coriaceous but faintly 3- or rarely 5-nerved, awnless: infloresence several closely imbricated spikelets, arranged in a linear, dense, nearly simple spike-like panicle. - Species 4, 1 in Medit. region, and 3 in S. Africa

(compounded of Diacrium and Cattleya). Orchidaceae. A genus established to include hybrids between the two genera, Diacrium and Cattleya. A hybrid between Diacrium bicornutum and Cattleya Mendelii is known as Diacattleya Sanderae. It was raised by Sander & Sons. The fis. are pure white, the lip with a pale yellow disk and small rose markings. G.C. III. 49:290. D. Colmaniae, Hort. (Diacrocattleya Colmanix is a hybridobetween Diacrium bicornutum and Cattleya intermedia variety nivea. G.C. III. 43:114. J.H. 56:167. It resembles a slender plant of Diacrium bicornutum: sepals and petals pure white, lip slightly tinged primrose-yellow. George V. Nash.


(through and point; the stems are surrounded by sheaths). Orchidacex. Four tropical Amer. epiphytes, closely allied to Epidendrum, with which they have been included. It differs from that genus in the fact that the column and lip are not united. Flowers showy, in loose racemes: leaves few, sheathing: pseudo-bulbs slender. Cult, of Epidendrum and Cattleya.


Benth. (Epidendrum bicornutum, Hook.). Pseudobulbs 1-2 ft. long, hollow, bearing dry sheaths: leaves short and leathery: raceme slender, 3-12-flowered; flowers white, with small crimson spots on the 3-lobed lip, fragrant. B.M. 3332. G.C III. 16:337. J.H. 111.33:29. O.R. 12:113; 16:81; 20:361. - A handsome orchid, requiring high temperature.

D. bidentatum, Hemsl. (Epidendrum bidentatum, Lindl.), of Mex., has been listed in trade catalogues, but it is practically unknown to cultivation, and is probably not now in the American trade.
