COUBLANDIA. A synonym of Muellera (which see). 
COUCH GRASS (Triticum repens). A noxious weed, 
very troublesome on agricultural land, but it is not so 
difficult to eradicate from a garden. One of the most 
effectual modes is to heavily manure a piece of ground 
infested, and plant with Brussels Sprouts, Kale, or Broccoli. 
These make strong growth and large foliage that smother 
the Couch Grass. Other methods are careful forking ont all 
pieces as they appear, and burning them at once. Much 
may be done by carefully collecting all pieces seen when 
digging the ground, and by preventing plants from 
going to seed, 
COUMAROUNA ODORATA. A synonym of 
Dipteryx odorata (which see). 
COUNTRYMAN’S TREACLE. See Ruta 
graveolens. 
COUSSAPOA (from Coussapowi, the Caribbean name 
of two of the species). Orp. Urticacer. A genus of 
stove, milky trees or shrubs, sometimes climbing over trees 
or epiphytal ; eighteen species have been described, natives 
of tropical South America, but according to Bentham and 
Hooker this number might be reduced. Flowers diccious, 
borne in a globose head; peduncles solitary or in pairs, 
axillary, the male heads few-flowered, often dichotomously 
paniculate, the female peduncles shorter, bearing one large 
head or a few clustered smaller ones. Fruit included, oblong. 
Leaves alternate, petiolate, entire, coriaceous, penniveined 
or three-nerved. For culture, see Ficus. 
C. dealbata (whitened).* The correct name of the plant 
described on p. 12, Vol. IL., as Ficus dealbata. 
COUTAREA. This genus embraces about five species. 
Flowers showy, odorous, terminal, solitary or in cymes of 
three ; calyx and corolla each with five or six lobes ; stamens 
five or six. Leaves opposite, shortly petiolate, membranous, 
ovate, acuminate; stipules short, acute. To the species 
described on p. 390, Vol. I., the following should be added : 
Cc. Scherffiana (Scherff’s).* . white, solitary, disposed in leafy 
cymes; corolla 2in. long, tubular-campanulate, ribbed, with 
spreading lobes. J. shortly petiolate, ovate, acuminate, 
attenuated at base, flat, shining; stipules broadly triangular. 
Ca divaricate. Colombia, 1876. A tall shrub. (I. H. 1878, 
COUVE TRONCHUDA ( Brassica oleracea costata). 
An excellent vegetable, not so well known in British 
gardens as its merits warrant. For first supplies, seeds 
should be sown early in February in gentle heat, and when 
large enough to handle the seedlings should be pricked in 
rich soil, afterwards gradually hardening the plants off and 
planting out in deeply-dug and rich ground, 34ft. apart each 
way. About the middle of March, a further sowing should 
be made in a cool frame or warm border outside, protecting 
the seeds from birds, and transplanting the plants when 
large enough to liberally-manured ground, at che distance 
apart named above. As the plants grow, diluted liquid 
manure applied occasionally will be of considerable value, 
so will also an application of loz. of nitrate of soda per 
square yard. Either or both of these will induce strong 
growth, a point to be aimed at, as the midribs of the large 
leaves are the best part of the vegetable when cooked in 
the same way as Sea Kale, and are of a most agreeable and 
distinct flavour.
