CORE-WOOD. See Anona palustris. 
CORM. A solid bulb. The enlarged base of the stem 
of a herbaceous plant, in which is stored a reserve of 
starch or other food-material ; a pseudo-bulb. In substance 
a Corm resembles a tuber, but it is generally more upright ; 
it produces from its upper surface leaves and buds, and from 
its lower, roots ; e.g., the Corms of Cyclamens and Crocuses. 
Corms are popularly but erroneously called Bulbs (which 
see).

CORNICULATE. Having an appendage or a process 
resembling a little spur or horn. 
CORN MARIGOLD. See Chrysanthemum se- 
getum.

Europe, temperate Asia and America, Mexico, and the 
Himalayas, are included in this genus. To those described 
on pp. 378-9, Vol. I., the following should be added : 
C. brachypoda (short-stalked). A synonym of C. macrophylla. 
C. capitata (headed). The correct name of Benthamia fragifera. 
C. corynostylis (club-styled). jl. borne.in sub-globose, white, 
silky-woolly corymbs; petals narrow, rather large; style club- 
shaped, equalling the filaments. J. opposite, ovate, ovate-oblong, 
or oblong-elliptic, acuminate, green or slightly woolly beneath. 
Himalayas, 1 (R. G. 1896, pp. 11, 286, t. 54, f. 4.)

are tinted with bright red. 1889. There is also a weeping form 
(pendula). 
C. Kousa (Kousa). The correct name of Benthamia japonica. 
Cc. macrophylla (large-leaved). _jl. white; calyx tube urn- 
shaped, whitish with appressed hairs ; panicles- terminal, erect, 
often 4in. to 5in. in diameter. July. 7. opposite or alternate, 
6in. long, 34in. broad, or larger, acuminate at apex, glaucous 
beneath, tinted with orange-red in autumn; petioles lin. long.
