AND GENERAL HORTICULTURE.

COR 



name of Dracaena indivisa. It is an exceed- 

 ingly useful plant for large specimens upon 

 the lawn, or for jardinieres, baskets, or vases, 

 as it will withstand some neglect and thrive 

 where many other plants would perish. This 

 species was introduced from New Zealand in 

 1850, and is propagated from seed, which 

 should be sown in boxes on bottom heat, or in 

 the green -house. As soon as the plants are 

 three inches high, prick out in small pots. 

 The young plants require a high temperature 

 and liberal waterings. Seedlings of this 

 species vary very much in character, and 

 many desirable varieties, such as C. indivisa 

 Veitchii, atropurpurea, lineata, etc., are in culti- 

 vation. C. Australia is also a most useful 

 species, the leaves being broader and more 

 drooping and graceful than the foregoing. A 

 number of the species and varieties cultivated 

 as Dracaenas, are placed under this genus by 

 many botanists, they being nearly all varieties 

 of C. terminalis (Dracaena), a species cultivated 

 everywhere throughout the tropics, and pro- 

 ducing innumerable varieties from seed. 



Coreo'psis. From koris, a bug, and opsis, like ; 

 referring to the appearance of the seeds. Nat. 

 Ord. Composite. 



Most of the showy annuals formerly known 

 by this name are now called Calliopsis, while 

 most of the perennial species are still left in 

 this genus. The perennial kinds are quite 

 hardy, the taller sorts requiring plenty of 

 room, but such free-flowering, showy gems as 

 C. auriculata, C. lanceolata, and C. tenuifolia 

 should have prominent positions. They are 

 valuable also for cutting, as the closer the 

 blooms are cut, the more they flower. They 

 are propagated by division of the roots, or 

 from seed, which, if sown where it is to re- 

 main, as soon as ripe, will flower early the fol- 

 lowing summer. The many species are 

 found from South Carolina southward to 

 Mexico. 



Coriaceous. Having the consistence of leather. 



Coria'ndrum. Coriander. From koris, a bug; 

 referring to the smell of the leaves. Nat. Ord. 

 UmbelliferoB. 



C. sativum, the only species, is a hardy 

 annual, and a native of the south of Europe. 

 It is a plant of little beauty, and of the easiest 

 culture. It is grown only for its seeds, which 

 are quite aromatic, and much used in flavor- 

 ing. The odor and taste depend upon a volatile 

 oil. 



Co'ris Monspeliensis. The only species of the 

 genus, a native of the western coasts of the 

 Mediterranean is a lowly-branching herbaceous 

 plant, bearing beautiful bright lilac flowers in 

 dense terminal spicate racemes. It belongs 

 to the Primrose family, and is an excellent 

 plant for the rock-garden. Increased by seed, 

 sown as soon as ripe. 



Cork Tree. Common. Quercus suber. 

 E. Indian. Adansonia digitata. 



Cork Wood. Hibiscus tiliaceus. 

 West Indian. Ochroma Lagopus, and Anona 

 palustris, which see. 



Corm. A fleshy, solid underground stem, hav- 

 ing the appearance of and often called a bulb, 

 and from which it is distinguished by its not 

 being scaly. The Gladiolus, Crocus, Babiana, 

 Sparaxis, etc., are Corms. 



Corn. See Zea. 



COR 



Corna'ceae. A small natural order of trees and 

 shrubs, rarely herbs, natives of the temperate 

 parts of Europe, Asia, and America. The 

 plants are used as tonics and in agues. From 

 the wood of C. mascula, the Turks obtain 

 the dye for their red fez. Some species are 

 grown as ornamental plants, and the common 

 Dogwood, which is very heavy and solid, is 

 much too commonly used in the United States 

 for baling hay, those who buy the hay very 

 properly esteeming it a fraudulent practice. 

 There are nine known genera and forty spe- 

 cies. Cornus, Aucuba, and Benthamia are 

 illustrative genera. 



Corn Flag. Gladiolus segetum. 

 Corn-flower. Blue. Centaurea Cyanus. 



Corn-Lily. Convolvulus arvensis and C. Se~ 



pium. 



Corn-Marigold. Chrysanthemum segetum. 

 Corn Pink and Corn Cockle. Lychnis Githago. 

 Corn Poppy. Papaver Rhceas. 

 Corn Salad. See Valerianella, 

 Corn Thistle. Carduus arvensis. 

 Cornel. Cornus sanguinea. 



Dwarf. Cornus suecica and C. Canadensis. 



Coruiculate. Terminating in a process resem- 

 bling a horn, as the fruit of Trapa bicornis. 

 If there are two horns the word bicornis is 

 used ; if three horns, tricornis, and so on. 



Co'rnus. Dogwood. From cornu, a horn ; in 

 reference to the hardness of the wood. Nat. 

 Ord. Cornacece. 



A genus consisting principally of trees and 

 shrubs. Some of the latter are very orna- 

 mental, the bark of the branches being of a 

 brilliant, glossy red in winter, and the leaves 

 of an intense purplish red in autumn. C. 

 florida, or Flowering Dogwood, is a tree grow- 

 ing from twelve to thirty feet high, and is 

 common in rocky woods from New York south- 

 ward. It is an interesting species, not only 

 for its symmetrical growth, but for its large 

 showy flowers, or rather the involucres which 

 surround the flowers (which are pure white 

 inside and tinged with violet on the outside), 

 and the showy fruit which succeeds them. It 

 is an appropriate and popular tree for ceme- 

 teries and a fine ornament for the lawn. C. 

 Canadensis, Bunch Berry, or Dwarf Cornel, is 

 a small herbaceous species, growing about six 

 inches high, from a creeping subterranean 

 root-stock, the upper leaves crowded into an 

 apparent whorl in sixes and fours, surround- 

 ing the clear white floral involucres one of 

 the neatest and most interesting plants for 

 the rock-garden. It is common in damp, cold 

 woods northward. 



Corolla. That part of a flower which intervenes 

 between the calyx and the stamens. Its 

 parts, which are called petals, are almost 

 always colored. 



Corolliflo'rae. A sub-class of Dicotyledons or 

 Exogens, characterized by the petals being 

 united, so as to form a monopetalous 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 illus- 

 trations.
