BOTANICAL TERMS AND DEFINITIONS. Xxiii 
Conjugate, or Yoked, (Conjugatum) leaves are so called that 
consist of one pair of pinnae or leaflets. 
Connate, (Connatum) applied to leaves, when two leaves are so 
united at their base as to have the appearance of one leaf. 
CoRDATUM, vide Heart-shaped. 
CoRiACEUM, vide Leathery. 
Corolla, (Corolla) the corolla consists of the delicate (and gene- 
rally coloured) petal or petals, forming what in common 
language are termed the blossoms; and in polypetalous 
flowers, the petals are usually called the leaves of th6 
flower. The corolla constitutes the beauty of the flower; 
and the odour and fragrancy of the plant frequently reside 
therein, as in the rose, jessamine, violet, &c. ; the corolla 
has a diversity of forms as well as of colour, and includes 
two parts, the petals and the nectary, the latter is some- 
times a part of the former, and sometimes separate from it. 
The various forms of the corolla, as wheel-shaped, bell- 
shaped, &c. will be described under their appropriate 
names.

Cotyledons, {Cotykdones) the side lobes of seeds furnishing 
nourishment and protection to the corculum, and which 
form the chief bulk of the seeds ; these lobes swell and 
expand in the ground, and as the stem ascends they are 
usually raised out of the ground, assume a green colour, 
and perform the functions of leaves until the young leaves 
unfold, when they generally wither. 
Crenate or Notched, (Crenatum) applied to leaves when the 
notches or teeth on the borders are rounded, and the 
notches not directed to either end of the leaf. 
Creeping, (Repens) applied to stems that run along the ground 
putting out roots as they proceed along; to roots that 
branch off horizontally and throw out fibres as they go.
