Couch Grass

: Agropyron repens.

Courantia

(personal name). Crassulaceae. Caulescent: leaves alternate, closely set, broad: flowers in a dense bracteate spike; calyx-lobes nearly equal, linear, brightly colored; corolla not angled, yellow; stamens 10; filaments united into a tube for half their length. Only one species. First brought into cultivated about 1842. for cultivation, see Cotyledon. C. rosea, Lem. (Cotyledon roseata, Baker). See No. 21, p. 870. J, n. Rose.

Coussapoa

(Caribbean name). Moraceae. Fifteen to 20 milky-juiced trees or shrubs of tropical S. Amer., 1 or 2 sometimes grown under glass, but apparently not in the American trade. They are sometimes scandent and epiphytic, like other Ficus-like things, sending down branches and completely enveloping the supporting tree and strangling it. Leaves alternate, stalked, thick, penninerved or 3-nerved, entire: flowers dioecious, in globose heads, the peduncles solitary or in pairs and axillary, the male clusters few-flowered and often paniculate, the females on shorter peduncles: fruit oblong, becoming succulent and with the including thickened perianth forming a mulberry-like multiple fruiting body. C. dealbata, Andre (Ficus dealbdta, Hort.), is described as a very beautiful greenhouse subject, with coriaceous elliptic leaves 1 ft. long and half as broad, white-silky beneath and deep green above. I.H. 17:4.

Cowania

(after James Cowan, an English merchant, who introduced many Peruvian and Mexican plants into England). Rosaceae. Some 4 or 5 small shrubs from the S. W. U. S. and from Mex., with small crowded leaves and handsome white or purple flowers; rarely cultivated in botanical collections. Closely related to Fal-lugia, but differing in the absence of bracts at the base of the calyx. Cult, and prop, like Fallugia, but apparently more tender: like that plant well adapted for planting in rockeries. C. mexicana, Don (C. Stans-ouridna, Torr.), has small crowded cuneate 3-7-lobed leaves and white flowers about 1 in. across. C. plicata, Don (C. purpurea, Zucc), has incisely serrate leaves and purple flowers Alfred Rehder.
