COB 



Cordato-sagittate. Between cordate and 

 sagittate. 



Cordiform. When a solid has the form of 

 cordate. 



Cordleafs.A. name given by Lindley to the 

 group Restiaceoe. 



Coreses. Dark red, broad, discoid bodies, 

 found beneath the epicarp or external 

 membrane of grapes. 



Coriaceous. Having the consistence of 

 'leather. 



Corky. Resembling cork in texture. 



Corm. A fleshy, solid underground stem, 

 having the appearance of a bulb, and 

 often called a bulb, from which it is distin- 

 guished by not being scaly. See Bulb. The 

 Gladiolus, Crocus, Babiana, and most of 

 the Iridaceae are Corms. ACorrn is only 

 a solid mass of feculent matter, which 

 modern botanists do not allow to be a 

 bulb, but call it an underground stem. 

 Corms do not require taking up so often 

 as bulbs; and when they are intend- 

 ed to remain for several years in the 

 ground they should be planted from four 

 to six inches deep at first, as every year a 

 new Corm will form above the old one; 

 and thus, if planted too near the surface, 

 the Corm, in a few years, will be pushed 

 out of the ground. 



Cornacece, (Dogwood.) A. small natural or- 

 der of polypetalous Calycifloral Dicotyle- 

 dons, belonging to Lindley 's*TJmbellal 

 Alliance. They are trees or shrubs, usu- 

 ally with opposite leaves having no stip- 

 ules. The flowers are produced in cy- 

 mose clusters, or in heads, surrounded 

 by an involucre. The fruit is a two-celled 

 drupe, (like a cherry. ) They are natives 

 of the temperate parts of Europe, Asia, 

 and America. The plants are used as 

 tonics and in aguea Cornus mescula is 

 the Akenia of the Greeks, and the Kizzil- 



COR 



jiek of the Turks. From the wood of 

 this plant 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 fraudu- 

 lent practice. There are nine known gen- 

 era and forty species. Cornus, Aucuba, 

 and Benthamia are illustrative genera. 



Corneous. Horny; hard and very close in 

 texture, but capable of being cut with- 

 out difficulty, the parts cut off not being 

 brittle; as the albumen of the Date, and 

 most other Palm seeds. 



Corniculate. Terminating in a process re- 

 sembling a horn, as the fruit of Trapa bi- 

 cornis. If there are two horns the word 

 bicornis isnised; if three horns, tricornis, 

 and so on. 



Cornu, (adj. Cornutus.) A horn-like pro- 

 cess, commonly solid, and usually a meta- 

 morphosed state of some organ. Also 

 employed in the -sense of Calcar, which 

 see. 



Corolla, (adj. Corollaris, Corottine.) That 

 part of a flower which intervenes between 

 the calyx and the stamens. Its parts are 

 called petals, which are almost always 

 colored. 



Corolliflorce. A sub-class of Dicotyledons or 

 Exogens, characterized by the petals be- 

 ing 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 separate- 

 ly below the ovary. Such orders as the 

 Heath family, the Gentians, and the La- 

 biates, may serve ds illustrations. 



Corona A coronet; literally a crown. Any 

 appendage that intervenes between the 

 corolla and stamens, as the cup of a Daf-
