NOMENCLATURE OF THE FLOWER. 



c. Hispid-having bristles, as in the field basil. 



d. Pedunculated furnished with little foot-stalks, as in 

 headed germander. 



e. Sessile having no foot-stalks, as in the dwarf germander. 



f. Roundish not perfectly round, as in the selago fruticosa. 



80. Umbel .-The umbella or umbel has several 

 stalks or rays, nearly equal in length, spreading from 

 one common centre, their summits forming a level, con- 

 vex or even globular surface, or more rarely a concave 

 surface. 



Tlie common fennel, knotted stone parsley, white-rot, ginseng, 

 hare's-ear, and the tribe of plants arranged in the natural order 

 umbellattv, maybe examined for a practical knowledge of this species 

 of inflorescence. (F. 14.) 



87. The varieties of this inflorescence, are from the 

 insertion of the umbel, either pedunculate or sessile ; 

 and from the division of the umbel, either simple or 



compound. 



I 



a. Pedunculate when the rays or flower-stalks proceed from a 

 peduncle. 



b. Sessile when the rays or flower-stalks proceed not from a 

 common peduncle, but from the stem or branch of the plant, as in 

 the knotted water-parsnip and small-fruited cherry tree. 



c. Simple when single-flowered,as in the knotted stone-parsley. 



d. Compound when each ray or stalk, bears an umbellula or 

 little umbel, as in the common feimel In this case, the first or 

 larger set of rays, constitute the universal umbel ; while the second 

 or lesser set of peduncles constitute i\\e partial vmbfl. 



88. Cyme: The cyma or cyme consists of several 

 flower-stalks having the general appearance of an umbel, 

 and agrees with it so far, that iti ccirmon stalks all
