COR 



The young plants require a high temperature 

 and liberal waterings. 



Coreopsis. From koris, a bug, and opsls, like; 

 referring to the appearance of the seeds. Linn. 

 Syngenesia-Frustranea. Nat. Ord. Asteracea;. 



Most of the showy annuals formerly known by 

 this name are now called Calliopsis, while most 

 of the perennial species are still left in the for- 

 mer genus. For the difference between the de- 

 rivation of the two names, and the culture of the 

 annual species, see Calliopsis. The perennial 

 kinds are quite hardy; but as they are tall grow- 

 ing, spreading plants, they require a great deal 

 of room, and should be planted at the back of 

 the borders. They will grow well in the bor- 

 der. Thev are propagated by division of the 

 roots, or from seed, which should be sown as 

 soon as ripe, where it is to remain. It will 

 flower early the following summer. The many 

 species are found from South Carolina south- 

 ward to Mexico. 



Coriandrum. Coriander. From koris, a bug; re- 

 ferring to the smell of the leaves. Linn. Pentan- 

 tlridrDigynia. Nat. Ord. Umbellifera;. 



C. saiivum, 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 flavoring. The 

 odor and taste depend upon a volatile oil. 



Cork Tree. See Quereus subtr. 



Cornel. See Cornus. 



Corn Flag. See Gladiolus. 



Corn Salad. See Vcderiandla. 



Cornus. Dogwood. From Cornu, a horn; in ref- 

 erence to the hardness of the wood. Linn. Te- 

 tmndia-Monogynia. Nat. Ord. Cornacece. 



A genus consisting principally of trees and 

 shrubs. Some of the latter are very ornamental, 

 the bark of the branches being of a brilliant, 

 glossy red in winter, and the leaves of an in- 

 tense purplish red in autumn. C. florida, or 

 Flowering Dogwood, is a tree growing from 

 twelve to thirty feet high, and is common in 

 rocky woods from New York southward. It is 



an interesting species, not only for its symmet- 

 growth, but for its large showy flowers, or 



rical 



rather the involucres which surround the flow- 

 ers, (which are pure white inside and tinned with 

 violet on the outside,) and the showy fruit which 

 succeeds them. It is an appropriate and popu- 

 lar tree for cemeteries, and a fine ornament for 

 the lawn. 



Corpnilla. From corona, a crown or garland; in 

 reference to the arrangement of the flowers. 

 Linn. Diadelphia-Decandria. Nat. Ord. FabacecK. 



A genus of pretty annual and perennial plants 

 found in Europe, Asia Minor, and North Africa, 

 but in the greatest abundance in countries bor- 

 dering on the Mediterranean Sea. Several of 

 the green-house species are very pretty flower- 

 ing shrubs of easy culture. C. (jlauat produces 

 its bright yellow, pea-shaped flowers in abund- 

 ance during the winter. Propagated by cut- 

 tings or from seeds, which ripen freely. The 

 species have been long under cultivation. 



Corpse Plant. One of the popular names of the 

 Monoiropa uniflora, a low-growing parasite on 

 roots, or growing on decomposing vegetable 

 matter like a fungus. It is also called Indian 

 Pipe. 



Correa. Named after Joseph Correa, a Portuguese 

 botanist. Linn. Odandria-Monoyyn'M. Nat. Ord. 



A genus of green-house evergreen shrubs, na- 



COR 



tives of New South Wales, New Holland, and 

 Australia, where they are sometimes called Fuch- 

 sias, from the slight resemblance the flowers have 

 to the Fuchsia. Several of the species have long 

 been grown in green-houses for the beauty of 

 their flowers, which are white, scarlet, or green ; 

 produced in June. The leaves of 0. alba are 

 said to be a very good substitute for tea. They 

 are increased by cuttings. Introduced in 1793. 

 Coryanthes. Helmet Flower. From korys, a hel- 

 met, and anihos, a flower; in reference to "the 

 shape of the lip or labellum. Linn. Gynandria- 

 Monogynia. Nat. Ord. Orchidacece. 



A genus of epiphytal Orchids found in Mex- 

 ico and South America. Among the many curi- 

 ous forms peculiar to this genus, perhaps the 

 most singular is that of 61 micraniha, which is 

 thus described in the Botanical Register: "The 

 plant has the habit of a Stanhopea, and pushes 

 forth from the base of its pseudo-bulbs a pendu- 

 lous 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 something more than 

 six inches from the tip of one sepal to that of 

 the opposite one. The sepals and petals are 

 nearly of the same color, being of an ochrey yel- 

 low, spotted irregularly with dull purple. The 

 lip is as fleshy and solid in its texture as the 

 sepals and petals are delicate. It is seated on a 

 deep purple stalk, nearly an inch long; this 

 stalk terminates in a hemispherical, greenish- 

 purple cup or cap ; and the latter, contracting at 

 its front edge, extends forward into a sort of sec- 

 ond stalk of a very vivid blood-color, the sides 

 of which are thinner than the center, turned 

 back, and marked with four or five very deep, 

 solid, sharp-edged plaits. These edges again 

 expand and form a second cup, less lobed than 

 the first, thinning away very much to the edges, 

 of a broadly conical figure, with a diameter of 

 at least two inches at the orifice ; this second cup 

 is of an ochrey yellow, streaked and spotted 

 with pale crimson, and seems intended to catch 

 a watery secretion, which drips into it from the 

 succulent horns, taking their origin in the base 

 of the column, and hanging over the center of 

 the cup." There are several species of the ge- 

 nus, all of which must be grown in a hot-house. 

 Propagated by division. They flower in June 

 and July. 



Corydalis. From korydalos, a lark ; the spur of 

 the flower resembling that of the lark. Linn. 

 Diadelphia-Hexandria. Nat. Ord. Famariucea:. 



A handsome genus of hardy tuberous-rooted, 

 herbaceous plants. Their flowers are showy, 

 and of many shades of color. They need an 

 open exposure. The perennial kinds may be 

 increased by division of the tubers about every 

 three years. The annual species require to be 

 sown in March where they are to remain. Sev- 

 eral of the species are indigenous, growing in 

 rocky places. They grow from one to three feet 

 high, bearing flowers of various colors. They 

 are easily propagated by seeds, and are very 

 pretty plants for rock-work. 



Corylus. Hazel-nut, Filbert. From korys, a 

 hood or helmet ; in reference to the calyx cov- 

 ering the nut. Linn. MonoRcia-Polyandria. Nat. 

 Ord. Corylacerv. 



This well-known deciduous shrub is common 

 throughout this country and Europe. The spe- 

 cies that yields the Filberts of commerce, C. Avel- 

 lana, is found growing in great abundance near 

 Avellana. a city of Naples, whence the specific
