COROLLA (adj. COROLLARIS, COROL- 

 LINE). Tliat part of a flower which 

 intervenes between the calyx and stamens ; 

 its parts are called petals. 



COROLLIFLOR^. A subclass of dico- 

 tyledons or Exogens, characterised by the 

 petals being united so as to form a monope- 

 talous corolla, inserted below the ovary, and 

 by the stamens being usually attached to the 

 corolla, but sometimes inserted separately 

 below the ovary. Such orders as the heath 

 family, the gentians, and the labiates, 

 may serve as illustrations. [J. H. B.] 



CORONA. A coronet. Any appendage 

 that intervenes between the corolla and 

 stamens, as the cup of a daffodil, or the 

 rays of a passion-flower. — STAMINEA. 

 A coronet formed from transformed sta- 

 mens. 



CORONANS. Situated on the top or crown 

 I of anything. Thus, the limb of the calyx 

 I may crown an ovary ; a gland at the apex 

 of the filament may crown a stamen. 



CORONARIA. A section of the caryo- 

 phyllaceous genus Lychnis. The type of 

 the group is the Rose Campion, Lychnis 

 coronaria, a native of S. Europe, com- 

 monly cultivated for its beauty. The 

 leaves of this plant are elliptical, white 

 with soft wool, as are the stems and calices ; 

 corolla with the petals nearly entire, 

 red or white, with a firm scale at the base 

 of the limb of each ; these scales form the 

 crown. The most natural group to com- 

 bine with the Rose Campion are the 

 remaining species of the discarded genus 

 Agrostemria, which have not the deeply- 

 bifid petals of Lychnis : this is the arrange- 

 ment of Fries. [J. T. S.] 



CORONATE. Furnished with a coronet. 

 Also used in the sense of Coronans. 



CORONILLA. A genus of pretty an- 

 nual or perennial plants of the pea family, 

 characterised by the flowers being borne 

 on stalked umbels, as well as by the articu- 

 lated, round, and nearly straight pod. The 

 plants of this genus are found in Europe, 

 Asia Minor, and North Africa, and in 

 greatest abundance in the countries bor- 

 dering on the Mediterranean Sea. Be- 

 tween twenty and thirty species are enu- 

 merated. The Scorpion Senna, C. Emerus, 

 a plant not unfrequently seen in gardens 

 is a much-branched pretty bush, about five 

 feet high. Its leaves are alternate, pin- 

 nate, from one to three inches long, and 

 composed of three or four pairs of small 

 wedge-shaped leaflets of a pea-green colour ; 

 these are said to produce a dye like indigo 

 by proper fermentation, and are also re- 

 ported as laxative. The yellow flowers, in 

 their form and arrangement, are a good 

 deal like those of the bird's-foot trefoil 

 (Lotus convciilatus), and are produced in 

 great abundance, making their appearance 

 iu May or June, and continuing in succes- 

 sion till the frost appears. The slender- 

 jointed pod has been compared to a scor- 

 pion's tail. C. varia is a perennial plant 



with creeping roots, and slender angular 

 stems, from one to three feet long. The 

 leaves, from two to three inches in length, 

 have numerous oblong leaflets, and the 

 flowers vary much in colour, being either 

 white, rose, or violet. It grows in various 

 parts of Southern Europe, and has been 

 recommended as a forage plant, but its 

 leaves are too bitter, and are even said to 

 be poisonous. The plants of this genus 

 bear much resemblance to each other, and 

 in almost all, the foliage is of a peculiar 

 pea-green colour. The yellow flowers of 

 many emit a strong odour. [A.A. B.] 



CORONULE. The small calyx-like body 

 which crowns the nucule of Chara. 



CORPUS. The mass of anything ; thus, 

 C. ligneum, or lignosum, signifies the mass 

 of the woody tissue of a plant, and G. 

 ■meduUare the mass of its cellular tissue in 

 the pith. 



CORPUSCULES. The spore-cases of cer- 

 tain fungals. — VERMIFORM. Spiral 

 vessels in a contracted, strangled, distorted 

 condition. 



CORREA. The pretty greenhouse shrubs 

 so named are now familiar to most per- 

 sons. They belong to a genus of Butacece, 

 and have simple dotted leaves, covered 

 more or less with down. The handsome 

 reddish or greenish flowers have a cup- 

 shaped nearly entire calyx ; a corolla of 

 four petals united into a tube ; eight sta- 

 mens attached beneath the ovary ; and four 

 one-celled ovaries placed on a small eight- 

 lobed disc, and covered with dense star- 

 like hairs, the styles confluent into one. 

 The fruit consists of four follicles bursting 

 each by two valves, and one-seeded by 

 abortion. These shrubs are natives of the 

 Southern and Eastern parts of Australia, 

 where they are sometimes called Native 

 Fuchsias, from the slight resemblance of 

 the blossoms to those of the fuchsia. It 

 is said too that the leaves of some of the 

 species are used as tea. [M. T. M.] 



CORRIGIOLA. A genus of Illecebracew, 

 small herbs growing in Europe (especially 

 the Mediterranean region), and at the Cape 

 of Good Hope. They have numerous 

 slender slightly-branched procumbent 

 stems, bearing linear and oblong fleshy 

 glaucous leaves ; stipules scarious, small ; 

 flowers small, green and white striped, 

 forming compound corymbs or racemes at 

 the end of the stem and branches ; calyx 

 five-parted, herbaceous, with a petaloid 

 margin ; petals five, very small ; stamens 

 five ; style very short, three-cleft ; fruit, a 

 hard nut enclosing a single seed. C. littor- 

 alis, found in the extreme south-west of 

 England, is a small annual with narrow 

 leaves extending to the tips of the stems,and 

 there intermixed with clusters of small 

 flowers which arise from the axils.and also 

 from a small terminal corymb. [J. T. S.]
