 umbellate, rising after the leaves. April. 1. ovate, acuminate, 

 pale beneath, and beset with adpressed hairs on both surfaces ; 

 bracts of the involucre large, white, roundish, retuse or nearly 

 obcordate. fr. oval. h. 20ft. to 30ft. United States, 1731. This

Cornus continued. 



February to April. I oval, acuminated, rather pubescent on both 

 surfaces. Branches smoothish. h, 10ft. to 15ft. Europe (Britain 

 excepted), 1599. SYN. C. mascula. (S. F. O. 151.) Of this there 

 is a form (variegata) having leaves variegated with white, and 

 another (elegantissimd) in which the foliage is beautifully marked 

 with creamy-white and tinged with red. Both are excellent 

 garden plants.

CORNTJTIA (named after Jacques Cornutus, a 

 Canada ; he died 

 his "Historia 



Plantanim Canadensium "). SYN. Hosta. OBD. 

 Verbenacece. A email tropical American genus, 

 containing about sir specis of ornamental green- 

 house evergreen shrubs, allied to Callicarpa. They 

 succeed well in a mixture of loam and peat. Cut- 

 tings strike readily in Band, if placed under a glass, 

 in bottom heat, during February or March. Perhaps 

 the only species in cultivation is C. pyramidata. 

 C. punctata (dotted). A synonym of C. pyramidata.

leaves ; umbels about equal in length to the four-leaved involucre. 



COBOKIA (from Korokia, the native name). 

 OED. Cornacece. A genus containing a couple of 

 species of ornamental half-hardy evergreen shrubs, 

 confined as far as is at present known to New 

 Zealand. Flowers axillary or terminal, solitary, or 

 in panicles ; calyx limb five-toothed ; petals five, 

 small, valvate, with a small scale at their base, 

 silky outside, yellow ; stamens five, filaments short. 

 Leaves alternate, exstipulate, evergreen, quite 

 entire, coriaceous. Branchlets and leaves below 

 silvery, with appressed pubescence. C. Cotoneaster 

 has proved quite hardy in a few districts, and would pro- 

 bably be such in many more, if afforded a little protection 

 during winter. Corokias are of easy culture, in moderately 

 good garden soil. They may be propagated by cuttings, 

 planted in sand, under a glass ; or by layers, put down in 

 autumn. 



C. bnddleioldes (Buddleia-like). fl. similar to those of C. 

 CoUmeater, but borne in short terminal panicles, from six to
