QUAMOCLIT. Cypress-vine. [Convolvulaceae.] Twin- 

 ing plants, the annual species of which should be 

 raised in a hot-bed in April, and planted out in May. The 

 seeds are very hard ; and a very successful mode of making 

 them germinate is to delay planting them till the warm days 

 of June : choose a hot noon, plant the seed, and immediately 

 water plentifully with boiling water. The plants will be 

 above gi'ound in thirt}^-six hours. The most common species 

 are — 



Q. coccinea (scarlet) ; half-hardy twining annual ; 12 feet ; flow- 

 ers scarlet, in July ; North America ; 1818. Q. vulgaris (com- 

 mon) ; half-hardy twining annual ; 8 feet ; flowers crimson, in 

 July ; East Indies ; 1629. There is a white-flowered variety. 



Q. digitata^ hcderifolia^ luteola, Fhoe?iicea, seroti'na, and 

 triloba are other annual species. 



Quaking-Grass. See Briza. ' 



QuELTiA. See Narcissus. The plants formerly called 

 by this name are now known as Narcissus. 



QuERCUS. Oak. [Amentaceffi.] Well-known valuable 

 trees. There are some hundred species and varieties ; but 

 only a few are valuable for the garden, as, generally, they 

 are too large-growing. The variegated and fastigate vari- 

 eties are very desirable. As Oaks are found in all parts of 

 the world, there are many tender species. The principal 

 North American species are — 



Q. Phellos (willow-leaved); 1723; and \2,x\q\.v Imvtilis ; 18 12.
