 name. Linn. 22, Or. 5, Nat. Or. Rhamnacece.

 glass,

Corolla, the coloured part of a flower, com- 

 posed of a petal or petals. The term is only 

 applied when the calyx is present, otherwise 

 it is called a perianth. 



CoROLLlFLbRjE. All plants are so called when 

 they have a monopetalous corolla not attached 

 to the calyx, the stamens inserted into the 

 corolla, and the ovarium superior — as in Con- 

 volvulus, &c. 



Cor6n A, a crown ; in botany applied to the 

 crown-like cup, which is found at the orifice 

 of the tube of the corolla in Narcissus, Pan- 

 cratium, and some others. 



CoronIlla, Necker. Derived from- corona, a 

 crown ; in reference to the arrangement of the 

 flowers. Linn. 17, Or. 4, Nat. Or. Pabacece. 

 An interesting genus ; several of the green- 

 house species are very pretty flowering shrubs, 

 and grow well in a mixture of peat and loam, 

 and may be increased by cuttings or seeds, 

 which ripen in abundance ; the herbaceous 

 species are some of them best grown in pots, 

 such as G. coronata and minima, as they re- 

 quire the protection of a frame in severe 

 weather ; increased by seeds or dividing at the 

 roots : the hardy annual kinds only require 

 to be sown in the open ground. Synonym'es :

Corpuscle, a small body, a particle of anything. 



CorrAa, Smith. In honour of Joseph Correa 

 da Serra, a distinguished Portuguese botanist. 

 Linn. 8, Or. 1, Nat. Or. Rutaeece. The species 

 of this genus are pretty greenhouse shrubs, 

 growing from three to six feet high ; they suc- 

 ceed best in a mixture of equal parts of sand 



and loam ; the species are increased by cut- 

 tings, which should not be planted too thick, 

 as they are liable to damp off. C. specibsa, 

 which is allowed to be the most difficult, may 

 be increased by inarching upon the common 

 sorts.

 Linn. 5, Or. 3, Nat. Or. Illecebracecs. These 

 are pretty annuals, only requiring to be sowu 

 in the open ground, and to be treated as other 

 hardy annuals.

Cortusa, Linn. In honour of J. A. Cortusus,

 plant, that succeeds well grown in a pot in a 

 mixture of peat and loam, but requires to be 

 protected in severe weather ; it is increased by 

 dividing the roots, or by seeds.

Coryanthes, Booker. Prom Tcorys, a helmet, 

 and anthos, a flower ; in allusion to the large 

 helmet-like appendage to the lip of the flower. 

 Linn. 20, Or. 1, Nat. Or. Orchidacece. The 

 species of this genus ought to be extensively 

 cultivated, because of their splendid and very 

 curiously-formed flowers. The most extra- 

 ordinary species of this genus is O. macrdntha, 

 of which the following is an abridged descrip- 

 tion, extracted from the Botanical Register, 

 ' ' The plant has the habit of a Stanhbpm, and 

 pushes forth from the base of its pseudo-bulbs 

 a pendulous scape, on which two or three 

 flowers are developed ; each flower is placed at 

 the end of a long, stiff, cylindrical-furrowed 

 ovary, and when expanded, measures some-
