Adam's needle — ,eschynanthus. i6i 



Adam's Needle. See Yucca. 



Adenocarpus. Lcguminosa. 



Seeds may be sown in March, the hardy species out- 

 doors, and the others in a cold house. Young cuttings 

 root freely in sand, if covered with a hand-glass. 



Adenophora. Campanulacea:. 



Propagated by seeds, sown as soon as ripe, in po's 

 placed in coldframjs. Also by suckers. 



Adenostoma. Rosacea-. 



Pro|3agated by cuttings of the young shoots, placed in 

 sand, under glass, in spring or autumn. 



Adlna. Riibiacece. 



Propagated by cuttings placed in rich, loamy soil, under 

 a hand glass, in heat. 



Adlumia (Allegheny Vine, Smoke Vine, Mountain Fringe). 

 FiimariaccLT. 

 Propagated by seeds. The plant is a biennial, bloom-

 at the root. 



.ffigle ( Bengal Quince, Citrus trifoliata). Rutacea:. 



Propagated by ripe cuttings, which will root in sand 

 under a hand-glass, in heat, if not deprived of any of their 

 lea\'es. Also by seeds. 



.ffirides. Orchidacea:. 



The only method of propagating this genus is by re- 

 moving the upper portion and planting it separately. It 

 should always be severed low enough to include a few 

 roots, otherwise a large proportion of leaves will be lost. 

 A somewhat dense shade, a moist atmosphere and careful 

 watering are essential until the young plant is established. 

 The old stool will soon send out lateral growths, which, 

 in time, may be separated and treated similarly. Vanda, 

 Saccolabium, Angrcecum, Renanthera, are increased in the 

 same way. (See under Orchids. ) 



.Sischynanthus. Gesneracea:. 



Propagated by seeds, which are very unsatisfactory. 

 By cuttings, which root freely in a well-drained pot, filled
