Corokia continued. 



twenty-flowered. I. shortly stalked, narrow lanceolate, or oblong- 

 lanceolate, 2in. to 6in. long, iin. wide. A. 10ft. to 40ft. 1835. 

 An upright shrub or small tree. (R. G. 679.) 



C. Cotoneaster (Cotoneaster).* fl. yellow, sweet-scented, Jin. 

 long; petals downy on the outer surface; peduncles solitary, 

 axillary. I. alternate or fascicled, Jin. to Iin. long, orbicular. 

 oblong-ovate or obovate, suddenly contracted in a flat linear 

 petiole; margins recurved. A low, rigid, spreading, much- 

 branched shrub. 



COROLLA. The inner whorl of floral envelopes. 



COROLLIFLORJE. A sub - class of Exogens, the 

 vast majority' of which are furnished with both calyx and 

 corolla. The petals are occasionally (though rarely) free, 

 sometimes altogether absent ; corolla generally irregular, 

 sometimes quite regular ; petals generally connate into 

 a two or more lobed corolla ; ovary either superior or 

 inferior ; stamens epigynous, epipetalous (rarely hypo- 

 gynous). 



CORONA. Literally, a crown ; botanically, applied 

 to any appendage that comes between the corolla and 

 the stamens, as the cup of a Daffodil or the rays of 

 a Passion-flower. 



CORONILLA (from corona, a crown ; the flowers are 

 disposed in heads or umbels at the tops of the peduncles). 

 Crown Vetch. OBD. Leguminosce. Ornamental shrubs, 

 or annual and perennial herbs. Peduncles axillary, 

 bearing at their tops umbels of pedicellate flowers. 

 Leaves impari-pinnate. The greenhouse species thrive 

 in a compost of two-thirds loam and one-third turfy 

 peat. Cuttings strike freely if placed in cold frames or 

 * cool house, under a hand glass, in spring, and, when 

 callused, introduced to gentle bottom heat. As soon as 

 rooted, they should be transferred to CO-sized pots, and 

 placed in a frame near the glass, plenty of drainage being 

 given. In order to make them grow bushy, the tops 

 should be freely pinched out; and, as the plants fill the 

 small pots with roots, they should be removed to 48-sized 

 ones, and again returned to the frame. Plenty of air 

 should be given, and, on mild days, the plants may be 

 entirely uncovered ; but they need constant attention to 

 watering, as, if allowed to get dry, they become naked 

 at the bottom, which altogether spoils their appearance. 

 Continue to change the pots as required, and, about the 

 first week in September, remove the plants to the green- 

 house, where they may remain until the end of May; 

 they should then be again transferred to the open air, in 

 a sheltered position. The hardy* species may be propa- 

 gated by division, in spring; or the young cuttings of 

 some will root in a cold frame. They are also increased 

 by seed, which should be sown as soon as ripe, in a cold 

 frame. The smaller-growing species are admirably adapted 

 for the rockery.

CORREA (named after Jose Francesco Correa de 

 Serra, 1750-1823, a learned Portuguese, who published 

 several treatises on plant physiology). ORD. Rutacece. 

 Greenhouse evergreen shrubs. Pedicels one-flowered, 

 solitary, twin or tern, axillary ; petals four, somewhat 

 connivent at the base, or joined into a long tube. Leaves 

 opposite, entire, clothed with starry hairs. This is a 

 most useful genus of decorative plants ; they are mainly 

 of free, moderately compact growth, so that, with a little 

 attention in pruning and training the plants whilst young, 

 it is not difficult to form wide uniform-shaped specimens 

 for decorative purposes in the greenhouse or conserva- 

 tory. If at all well managed, few plants flower more 

 profusely, or continue in blossom a longer time. The advan- 

 tage they have over many subjects of the same class, when 

 used for conservatory decoration, is considerable, inasmuch 

 as they will bear to be placed, whilst in flower, in nearer 

 proximity to other plants for contrast, and at a distance 

 from the light, without taking much harm ; and neither 

 foliage nor wood are subject to attacks of mildew, or 

 likely to suffer from damp. Although . Correas may be 

 struck from cuttings as readily as most other hard-wooded 

 plants, they are, for the most part, grafted on C. alba. 

 By employing this mode of propagation, the better kinds
