the first Branmer, as the stocks will produce plenty of small fibrous roots 

 by the time they are wanted for use. Some of the dwarf species, like 

 the California Buckeye (JE. Califomica), sad. the Dwarf Buckeye {JB. 

 parviJUn-d), of the Eastern States, are readily increased by dividiag up the 

 old stools or clumps of stems, 



Aganosoma. — Showy greenhouse shrubs, principally from India. 

 Propagated by cuttings under glass with gentle bottom heat. 



Aga'petes. — Deciduo*5 shrubs from the mountains of India. They 

 are closely allied to the Huckleberries (VacciniacetE), but require the 

 heat of a wai-m greenhoufiC. Propagated by seeds, and half-ripened 

 cuttings under glass. 



Agathophyllum (Madagascar Nutmeg). — ^An evergreen tree closely 

 allied to the Laui'els, the 1& tot having the fragrance of the clove. 

 Eequires the heat of a warm greenhouse. Propagated very readily by 

 cuttings of the gi'een shoots. 



Agathosma (Bucco). — Small, evergreen, heath-like shrubs from the 

 Cape of Good Hope, thriving in a cool gi-eenhouse in winter and in a 

 half shady position dming the sumn ■er. Propagated by cuttings of the 

 green, succulent shoots under glass. 



Ailantus (Tree of Heaven). — A wf'l Isnown tree from China ; the 

 Btaminate fiowers exhaling a disagreeable, nauseating odor. Propagated 

 by seeds preserved in a dry, cool place orer winter and then sown in 

 spring and lightly covered. Also increaseo. by suckers and cuttings of 

 the roots. The latter modes are not recommended except for propagat- 

 ing the pistillate trees, the flowers of which arr odorless. 



Alcebia. — A very hardy and handsome twining; shrub from Japan. 

 Only one species as yet known, the A. quinata, or Five-leafletted. Bead- 

 Uy propagated by layers of either the old or young choots. 



Alhagi (Manna Tree). — Small shi-ubs with pea-shaped flowers. Na- 

 tives of Caucasus. One of the species, the A. mauri^ um, yields the 

 substance known as " manna," a natm'al exudation ot the leaves and 

 branches. Propagated by seed, and cuttings of the green s^oots placed 

 where they wiL receive bottom heat. 



Alnus (Alder). — Deciduous trees and shrubs, mostly nativer of eoW 

 20untries. The species are usually propagated by seeds preserved in a 

 dry, cool place over winter, and sown on the surface of the sou in spring 

 and thinly covered with moss or some light vegetable mold, which sl'ould 

 be kept constantly moist until the plants appear. Varieties are propa- 

 gated by cuttings of ripe wood, layers and gi-afting upon free growing 

 stocks. The recently introduced Japan Alder (.il. flrma), succeeds best 

 when grafted on the Europecn Sticky Alder (A. glutinosa). 



Amelanchier (Juneberry, Shadbush, Etc.) — Deciduous trees and 

 shrubs. The North American species aa-e extremely variable, producing 

 many natural and widely different varieties. Some gj-ow to trees thirty 

 or more feet in height, others are merely dwarf shrubs two or three feet
