broadly oval, acuminated, clothed with hoary 

 toinentum beneath. Corymbs depressed, 

 spreading. Branches slightly tinged with red. 

 Leaves broad, waved on their edges. Flowers 

 white, as in most of the species." Pomes glo- 

 bose, at first blue, but at length becoming 

 white. (Don's Mill., iii. p. 399.) A native of 

 North America, from Canada to Virginia, 

 on the banks of rivers ; and probably of Cali- 

 fornia. A shrub, growing from 5ft. to 10 ft. 

 high, flowering in June and July. Introduced 

 in 1784, and not unfrequent in collections. 

 There are plants in the Horticultural Society's Garden, and in the collec- 

 tion of Messrs. Loddiges, which are readily distinguished from those of all 

 the other sorts, by their broader leaves, and their rough warted branches.

 Mill., iii. p. 398.) A native of Nepal, about Narainhetty, Katmandu, and the Valley of Dhoon ; 

 where it forms a tree, growing from 10ft. to 15 ft. in height. It is said to have been introduced in 

 1818 ; but we have never seen it 



* C. macroplti/!ln Wall, has broad, ovate, acuminated leaves, and small pomes, about the size of 

 black pepper. It is a native of the Himalaya Mountains, but it is not yet introduced. 



3fe C. rjerdlsa H. B. et Kunth (7>w'.v .1/-7/., 3. p. 399.) is a native of the environs of Mexico, and is 

 closely allied to C. sanguinea ; but only dried specimens of it have yet been seen in Britain. 



ii. Involucrdtee Dec. 



Derivation. From invalucrum, an involucre, with which the heads of flowers are severally sur- 

 rounded. 



Sect. Char. Flowers disposed in heads or umbels, surrounded by coloured 

 involucres, which are usually composed of 4 leaves. (Dec. Prod., iv. p. 273.) 



A. Trees with white capitate Flowers. 



% C. tlisciflura Moc. et Sesse (Dec. Prod., 4. p. 273. ; C. grandis Cham, et Schlecht.} has smooth 

 branches, with lanceolate leaves, and ovate fruit. It is a native of Mexico, near Jalapa, but has not

 Tree ; Cornelia ; Cornouiller male, Comes, Corneilles, Fr. ; Kornel Kir?ehe Hartriegel, Ger. 



Derivation. The name of mas. has been applied to this species since the days of Theophrastus ; in all 

 probability, because young plants are barren for many years after they show flowers ; these flowers 

 being furnished with stamens only. For an opposite reason, the name of Cornus fe'mina was given 

 to C. sangufnea. (See p. 1010.) The name of Cornelian Cherry relates to the beautiful colour of 

 the fruit, which resembles that of a cornelian.
