THE DICTIONARY OF GARDENING, 



Clitoria continued. 



July. 1. impari-pinnate, with two to four pairs of oval or ovate 

 leaflets. India, 1739. SYN. Ternatea, vulgarix. (B. M. 1542.) 

 There are varieties of this species with blue and white flowers, 

 and also variegated with those colours. 



OLIVIA (named after a Duchess of Northumberland, a 

 member of the Clive family). OBD. Amaryllidece. SYN. 

 Imantophyllum (often erroneously written Imatophyllum) . 

 Handsome greenhouse evergreen bulbs, requiring a high 

 temperature, and plenty of moisture when growing. 

 During the season of rest, they need very little heat 

 or moisture, only just enough of the latter to keep the 

 soil from being dust-dry. Propagated by divisions, or by 

 seed. There are three species, all natives of South 

 Africa, the best being the one here described. 

 C. Gardenl. See Imantophyllum Garden!. 

 C. miniata. See Imantopbyllum miniatum. 

 C. nobllis (noble).* fl. red, yellow, forty-eight to fifty in a 

 pendulous umbel ; perianth tubular, segments imbricate, outer 

 shorter than inner. May. Z. distichous, coriaceous, strap-shaped, 

 sheathing at base, retuse and oblique at apex ; margin rough, 

 A. lift. 1823. SYN. Imantophyllum AUoni. (B. M. 2856.) 

 CLOCHES. See Bell Glasses. 

 CLOMENOCOMA MONTANA. See Dysodia. 

 CLOUDBERRY. See Rubus Chamsemorus. 

 CLOUD GRASS. See Agfrostis nebnlosa. 

 CLOVE, or CLOVE FINE. See Dianthus Caryo- 

 phyllus. 



CLOVER. See Trifolium. 

 CLOVE-TREE. See Caryophyllus. 

 CLOWESIA (named after the late Rev. J. Clowes, at 

 one time an extensive Orchid grower, and in whose esta- 

 blishment the genus first flowered in this country). OBD. 

 Orchideoe. An interesting little stove epiphytal Orchid, 

 allied to Catasetum, and requiring the same treatment. 

 C. rosea (rosy). JL delicate white, tinged with pink; scapes 

 radical, many-flowered, erect, shorter than the leaves. March. 

 Pseudo-bulb fleshy, leafy. A. Sin. Brazil, 1842. (B. B. 29, 39.) 

 CLUBBING. The formation of protuberances on 

 roots, particularly those of the Brassica tribe, proving 

 the most destructive disease these are subject to. It ia 

 generally caused by some insect. See Cabbage. 



CLUB GALL WEEVTL. See Cabbage Gall 

 Weevil. 



CLUB MOSS. See Lycopodium. 



CLUB RUSH. See Scirpa and Typha. 



CLUMPS. This term is applied to groups of two or 

 more trees, shrubs, or other plants, arranged to form an 

 isolated mass. It may extend to almost endless combina- 

 tions in landscape gardening, from a conspicuous group of 

 fine trees in a park to one of small shrubs on a lawn. 

 In selecting a position, or planting a Clump of any 

 description, attention should be given to surrounding con- 

 ditions, and forethought exercised as to its appearance 

 when fully developed. This especially applies to planting 

 Clumps of permanent trees. Rhododendrons are probably 

 most largely grown as Clumps on lawns ; but many other 

 shrubs are very useful and attractive, if arranged in this 

 way. Overcrowding should, in aU cases, be avoided. 



CLUSIA (named in honour of Charles de la Cluse or 

 Clusius, of Artois, an acute botanist, author of " Historia 

 Plantarum," and many other works; born in 1526 and 

 died in 1609). Balsam-tree. OBD. Guttiferce. Stove ever- 

 green trees and shrubs, often epiphytal, with large 

 coriaceous, opposite leaves, and usually tetragonal stems' 

 abounding in viscid juice. There are about sixty species! 

 nearly all natives of tropical parts of the Western hemi- 

 sphere. They grow well in light sandy soil. The pots 

 will require to be thoroughly drained. Cuttings of half- 

 ripe shoots will strike in sand, if placed under a bell 

 glass, and given plenty of bottom heat. 

 C. alba (white). fl. white, h. 30ft. West Indies, 1752. 

 C. flava (yellow), n. yellow, h. 30ft. Jamaica, &c., 1759. 



Clusia continued. 



C. rosea (rose-coloured), fl. beautiful rose-coloured, large ; calyx 

 the same colour, five to six-leaved ; tops of dense nectaries awl- 

 shaped. July. 1. obovate, obtuse, veinless, sometimes ernar- 

 ginate, on short, striated petioles, h. 7ft. to 20ft. Carolina, 

 1692 (on rocks and trees). 



CLUSTER CHERRY. An old name for the Bird 

 Cherry. See Cerasus Padus. 



CLUSTER-FLOWERED YEW. See Cephalo- 

 taxus. 



CLUSTER FINE. See Finns Pinaster. 

 CLUYTIA (named after Outgers Cluyt, 1590-1650, 

 a Dutchman, who was Professor of Botany at Leyden). 

 ORD. Euphorbiaceae. Greenhouse evergreen shrubs, with 

 white flowers. They thrive in a compost of sandy loam 

 and fibry peat. Cuttings of small side shoots will root in 

 sand, over a layer of sandy peat, covered with a bell glass ; 

 points of shoots, before they become hard, will serve as 

 substitutes for cuttings, when the latter are not obtain- 

 able. This genus contains about thirty species, from 

 tropical and Southern Africa; they are of little beauty 

 or interest, and those which have been introduced are 

 rarely seen in cultivation out of botanical gardens. 

 CLYFEATE. Scutate ; shaped like a Roman buckler. 



FIG. 477. FRUITING BRANCH OF CNEORUM TRICOCCUM. 



CNEORUM (from Cneoron, a name given to some shrub 

 resembling an Olive, by Hippocrates and Theophrastus). 

 Widow-wail. OBD. Simarubece. Very ornamental green- 

 house or half-hardy evergreen sub-shrubs, with axillary 

 yellow flowers and entire linear-oblong leaves. They 

 thrive in a compost of peat and fibry loam, to which a 

 little silver sand has been added. Ripened cuttings root 

 freely, about April, in sand, under a bell glass. Cneorums 

 succeed fairly well outside, in an open border, in the 

 southern counties ; but in more northern localities, they 

 require the shelter of a south wall. The genus is confined
