COUCH GRASS. 



Couch Grass (Triticum repens) is a near ally 

 of the cultivated Wheat plant, but the usefulness 

 of its brothers must not he taken as a guarantee of 

 its own, for it is one of the roost troublesome 

 weeds on the face of the earth. A heavy appli- 

 cation of salt in hot, dry weather will temporarily 

 clear it from gravel walks ; but it returns re- 

 invigorated thereby the next season. No remedy 

 is thoroughly effective except digging every 

 scrap of the creeping root up and burning it on 

 the smother fire. Twitch and Squitch are names 

 also applied to it. If not elegant they are ex- 

 pressive. 



COUROUPITA. (CAXXON BALI. TUBE.) 

 Under cultivation, Couroupita guianensis (prd. 

 Myrtacese) requires a roomy stove and a compost 

 of loam, peat, and sand. The large fruits are like 

 cannon jkulls, and they make a loud report when 

 opening: The pulp is edible, and the shell is used 

 in Guiana as a drinking vessel.

COUSINIA. 



A genus of little grown annual, biennial, or 

 perennial plants (prd. Composite), which can be 

 grown in common soil, and are raised by seeds 

 sown at the beginning of April in the open. The 

 perennials can be divided in spring. Few are in 

 cultivation, but Hystrix, 2' high, which is a hardy 

 biennial and flowers in June, is sometimes seen. 

 It lias purplish blooms, and the leaves are covered 

 with a cobweb-like wool. Others are carduiformis, 

 cynaroides, macrocephala, tenella, uncinata, and 

 wolgensis. 



COUTAREA. 



These stove evergreen trees (ord. Rubiaceae) are 

 very handsome, and have economic value, inns- 

 much as the Cinchona bark of British Guiana is 

 the produce of the trees. They grow well in loam 

 and peat, and spring cuttings root readily in sandy 

 soil under a bell-glass over bottom heat. 



COUTOUBEA. 



The two species of this genus (prd. Gentianese) 

 are respectively a stove annual and a stove bien- 



Coulteria, (see C<esalpinla).
