Conical, broad and round at the base, tapering gradually upwards ; as the 

 receptacle of Daisy. 



Conjugate, applied to leaflets which are joined together in pairs. 



Connate, joined together at the base, as the petals of Fumitory. When the 

 bases of the two leaves are combined at the base, with the stem running 

 through the middle, they are said to be connate. 



Connivent, converging. 



Converging, having a gradually inward direction, 



Convex, having a globular surface. 



Convolute, rolled together. 



Cordate, heart shaped ; as the leaves of Burdock, Coltsfoot, Dead-Nettie. 

 Wben joined by a hyphen to another word, it signifies a figure between 

 the two ; as cordate -reniform, signifies between heart-shaped and 

 kidney-shaped ; cordate-ovate, between heart-shaped and egg-shaped ; 

 cordate -oblong, between heart-shaped and oblong ; as the lower leaves 

 of Betony, Clary. 



Coriaceous, thick and tough ; having the consistence of leather ; as the 

 seed-vessel of Asarabacca, the leaves of Black Hellebore. 



Corneous, horny, resembling horn. 



Cormus, a subterranean bud, or dilated stem, internally fleshy, externally 

 clothed with membranous withered scales ; it is commonly but im- 

 properly called a solid bulb. See Colchicum and Saffron. 



Corolla, the inner envelope of the flower, immediately within the calyx ; it 

 is of one piece or of many leaves called petals, usually coloured, and 

 of a thin delicate texture. 



Corolline, of the corolla. 



Corona, crown ; applied to the crown -like cup, found at the orifice of the 

 tube of the corolla in some flowers. 



Corrugated, having a wrinkled or shrivelled appearance. 



Cortical, of or belonging to bark. 



Corymb, a kind of raceme, in which the stalks of the lower flowers are much

 Feverfew. 



Costate, ribbed. 



Cotyledons, the embryo leaves or lobes of the seed ; the leaves which first ap- 

 pear after germination. The number and position of the cotyledons form 

 the basis of the modern natural system of botany founded by Jussieu. 

 Plants that have two cotyledons, as the Apple, Bean, Crowfoot, and many 

 others, are named Dicotyledonous ; those with but one cotyledon, as 

 Arum, Lily, the Grasses, &c, are called Monocotyledonous ; those which 

 have no cotyledon, as Ferns, Mosses, &c, are Acotyledonous. 



Creeping, trailing upon the ground, and taking root at the joints. 



Crenated, scolloped at the margin ; as the leaves of Daisy, Foxglove, 

 Ground Ivy, &c Crenate -serrate, between crenate and serrate ; as the
