HENDERSON'S HANDBOOK OF PLANTS 



COR 



Corona. A coronet; literally a crown. Any 

 appendage that intervenes between the corolla 

 and stamens, as the cup of a Daffodil or the 

 rays of a Passion Flower, or the crown-like 

 cup which is found at the orifice of the tube 

 of the corolla of the Narcissus, etc. Corona 

 staminea, is a coronet formed from trans- 

 formed stamens. 



Coroni'lla. From corona, a crown or garland ; 

 in reference to the arrangement of the flow- 

 ers. Nat. Ord. Leguminosce. 



A genus of pretty annual and perennial 

 plants found in Europe, Asia Minor and north 

 Africa, but in the greatest abundance in coun- 

 tries bordering on the Mediterranean Sea. 

 Several of the green-house species are very 

 pretty flowering shrubs of easy culture. C. 

 glauca produces its bright yellow, pea-shaped 

 flowers in abundance during the winter, and 

 with its beautiful variegated variety is invalu- 

 able for winter green-house decoration. Prop- 

 agated by cuttings or from seeds, which ripen 

 freely. 



Corpse Plant. One of the popular names of 

 the Monotropa uniflora, a low-growing para- 

 site on roots, or growing on decomposing 

 vegetable matter, like a fungus. It is also 

 called Indian Pipe. 



Co'rrea. Named after Joseph Correa, a Portu- 

 guese botanist. Nat. Ord. Rutacem. 



A genus of green-house evergreen shrubs, 

 natives of New South Wales, New Holland 

 and Australia, where they are sometimes 

 called Fuchsias, 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 C. 'alba are said to be a very 

 good substitute for tea. They are increased 

 by cuttings. Introduced in 1793. 



Corrugated. When the parts are crumpled up 

 irregularly, as the petals of the Poppy or the 

 skin of some seeds. 



Cortex. The bark or cortical layer. 



Corticate. Like bark ; harder externally than 

 internally ; having a rind, as the orange. 



Corya'nthes. Helmet Flower. From korya, a 

 helmet, and anthos, a flower ; in reference to 

 the shape of the lip or labellum. Nat. Ord. 

 Orchidacece. 



A genus of epiphytal Orchids found in Mex- 

 ico and South America. Among the many 

 curious forms peculiar to this genus, perhaps 

 the most singular is that of C. macrantha, 

 which is thus described in the Botanical Reg- 

 ister : ' ' The plant has the habit of a Stanhopea, 

 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 

 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 yellow, 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 second stalk of 



COR 



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, takiug 

 their origin in the base of the column, and 

 hanging over the center of the cup." There 

 are several species of the genus, all of which 

 must be grown in a hot house. Propagated 

 by division. They flower in June and July. 



Cory'dalis. From korydalos, a lark; the spur 

 of the flower resembling that of the lark. Nat. 

 Ord. Fumariacece. 



A handsome genus of hardy tuberous root- 

 ed, 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. C. nobilis, a native 

 of Siberia, is one of the most beautiful and 

 early flowering of light yellow colored hardy 

 border plants. The annual species require to 

 be sown in March where they are to remain. 

 Several of the species are indigenous, grow- 

 ing in rocky places, and 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. 



Coryla'ceee. This order founded by Lindley, 

 of which the principal genera are Carpinus, 

 Corylus, Castanea, Fagris, and Quercus, is now 

 included under Cupuliferce. 



Corylo'psis. From korylos, the Hazel tree, and 

 opsis, like ; nut-like. Nat. Ord. Hamameli- 

 dacece. 



Very ornamental and interesting, hardy 

 deciduous shrubs ; in habit, leaves and inflor- 

 escence resembling Hazels. Flowers appearing 

 before the leaves in pendulous racemes, each 

 flower nearly sessile with a large sheathing 

 yellow bract. Natives of the Himalayas arid 

 Japan. 



Co'rylus. Hazel-nut, Filbert. From korys, a 

 hood or helmet; in reference to the calyx 

 covering the nut. Nat. Ord. Corylacece. 



This well-known deciduous shrub, is com- 

 mon throughout this country and Europe. 

 The species that yields the Filbert of com- 

 merce, C. Avellana, is found growing in great 

 abundance near Avellana, a city of Naples, 

 whence the specific name. It is a strong grow- 

 ing shrub from ten to fifteen fdet high. 

 The Filbert is monoacious; the male 

 catkins make their appearance in Sep- 

 tember, on the previous year's growth, 

 but are not fully developed or expanded until 

 the succeeding season, when the female 

 flowers appear about the first of February, 

 and in April they are in full flower. The 

 flowers are small and of a beautiful red color. 

 The fruit of this species forms an important 

 article of export from Naples. C. Colurna, a 

 native of Turkey and Asia, is a tall-growing 

 tree, often reaching a height of sixty feet. The 

 nuts are larger than those of the preceding 

 species, and are of excellent quality. This 

 country is represented by two species, 6'.
