longitudinally. There are ten stamens, five I 

 sterile, concealed in the furrows of the 

 claws of the petals and adherent to their 

 base, and five fertile, opposite to the lobes 

 of the disc, longer than the sterile ones, and 

 having their anthers tipped with a minute 

 sessile gland. The fruit is a capsule of 

 five carpels, each provided with a small 

 born-like process at the top and opening : 

 by two valves. C. album is the best known 

 species. [M. T. M.l | 



COLEOPHORA. The name given to a tree 

 of the daphne family found m Brazil, Hie 

 leaves of which are not known. Prom the 

 little scaly buds, which are scattered over 

 the trunk of the tree, the flowers proceed. 

 They are small, yellow and brown, and borne 

 on short racemes. The tubular calyx has a 

 four or five-toothed border fringed with 

 hairs, and inside of it, and surrounding | 

 the stalked ovary, is a little four-toothed J 

 petal-like cup, about half the length of the 

 calyx tube. The stalked ovary, surrounded 

 by the peculiar cup, serves to distinguish 

 the genus. [A. A. B.] 



COLEOPHYLL, or COLEOPTILE. The 

 first leaf which follows the cotyledon in 

 endogens, and ensheaths the succeeding 

 leaves. 



COLEORHIZA. The sheath formed at 

 the base of an endogenous embryo, where 

 it is pierced by the true radicle. 



COLEOSTYLIS. Herbaceous plants cover- | 

 ed with glandular hairs, natives of New Hoi- i 

 land, and closely allied to Stylidium, but dis- 

 tinguishable from it by the following cha- 

 racters : — The limb of the corolla is divided i 

 into five segments, four of like form, 

 stalked; the fifth or lip is unlike, jointed to | 

 the tube of the corolla, stalked, its blade 

 boat-shaped, notched at the point or pro- 

 longed ; and the column, which consists of 

 the stamens and style united together, is 

 shorter than the lip, erect, and passing at 

 its base through a kind of sheath, whence 

 the name. [M. T. Mj 



COLESEED, or COLLARD. The Rape, 

 Brassica Nwpus. 



COLESTJLA. The small membranous 

 bag which contains the spore-case of 

 liverworts. 



COLEWORT, or COLLET. The Cabbage, 

 Brassica oleracea. 



COLEUS. A considerable genus of La- 

 biatee, found in Asia and Africa. It con- 

 sists of annual herbs, sometimes with pe- 

 rennial stocks, rarely shrubs. The flowers 

 are in loose or dense six or many-flowered 

 verticillasters. The calyx is ovate-cam- 

 panulate, bending back when in fruit, and 

 the limb is five-toothed or bilabiate. The 

 corolla-tube is longer than the calyx, and 

 the limb is bilabiate with the upper lip ob- 

 tusely three to four-cleft, and the lower en- 

 tire, lengthened, and con cave, often curved 

 and enclosing the four stamens. The style 

 is bifid with subulate lobes. The nucule is 

 compressed and smooth. [W. C] 



COLICODENDRON. A genus of Cappa- 

 ridaceee, consisting of tropical American 

 trees or shrubs, covered with small star- 

 shaped hairs, and having clusters of 

 flowers, with a cup-shaped calyx, divided 

 into four or five segments, provided in- 

 ternally and at their base with a petaloid 

 scale. The four or five petals are inserted 

 on to the calyx; the stamens are from 

 eight to twenty, inserted on a stalk, and 

 united at the base into a shallow cup ; the 

 ovary is also on a long stalk. The fruit is 

 a roundish or elongated berry, knotted 

 and containing several kidney-shaped 

 seeds. The genus possesses an acrid prin- 

 ciple, which, according to Martius, is so 

 potent in C. Teo as to he dangerous to 

 mules and horses. [M. T. M.] 



COLIC ROOT. Aletris farinosa. 



COLIGNONIA. A genus of Peruvian 

 herbs or undershrubs belonging to the 

 order Nyctaginacece, and having flowers ar- 

 ranged in an umbellate manner, surround- 

 ed by deciduous bracts. The perianth is 

 coloured, bell-shaped, with a five-cleft 

 limb from which the five stamens pro- 

 trude ; the style is simple ; the stigma is 

 fringed. The fruit is hardened, pentangu- 

 lar, crowned by the upper part of the peri- 

 anth. [M. T. M.] 



COLLABIUM nebulosum. A terrestrial 

 orchid, with a slender creeping rhizome, 

 known only by a brief description of 

 Blume, who says it has distant stalked 

 membranous radical leaves clouded with 

 purple, and small nodding spiked flowers, 

 whose sepals are reflexed. 



COLLANIA. A genus of amaryllids al- 

 lied to Alstromeria, from which it differs 

 in having a pulpy fruit, and in 'the great 

 prominence of the operculum of the ger- 

 men, making it at least half superior in- 

 stead of inferior.' The species are natives 

 of Peru, and are very ornamental plants. 

 They have rigid erect stems curved at the 

 summit, bearing simple rigid leaves, and a 

 pendulous umbel of flowers, of which the 

 six-leaved perianth is tube-formed and not 

 at all spreading. C. dulcishas stems about 

 a foot high, erect with a little tortuosity 

 but not prehensile, clothed with oblong 

 obtuse glaucous leaves,which are narrowed 

 at the base, and terminating in a four- 

 flowered umbel of cylindraceous purple 

 flowers tipped with green, the three petal- 

 ine segments longer and bright green. 

 This plant is called' Campanulas coloradas' 

 in its native country, and the fruit is 

 sweet and agreeable to the taste, and much 

 sought by children, the seeds being en- 

 veloped in a reddish gelatinous sub- 

 stance. G. andimarcana is a much 

 larger plant, with a stem terminating in 

 a fine umbel of leafy racemes of large 

 pendulous sub-cylindraceous flowers, up- 

 wards of two inches Jong, of which the 

 sepals are orange red tipped with black, 

 and the petals yellow tipped with green. 

 The name Collania has also been applied to
