ALANGIUM (from the Malabar name). Including 

 Mdrlea. Alungiacese, formerly included in Corndcex. 

 Trees or shrubs, rarely grown in temperate regions 

 for their handsome large foliage and fragrant fls. A 

 genus of over 20 species of shrubs or small trees of the 

 Old World tropics, with alternate entire or lobed ever- 

 green or deciduous Ivs. and small, perfect whitish, often 

 fragrant, fls. in axillary clusters; calyx small, campanu- 

 late; petals 4-10, linear, usually laxly reflcxed; stamens 

 4-30; ovary inferior, style simple, elongated: fr. a 

 1-seeded drupe. Sometimes cult, in Old World gardens, 

 either as stove plants or out-of-doors in warmer regions, 

 but probably not in the American trade.

 to GO ft.: Ivs. ovate, entire or slightly lobed, acuminate,- usually 

 rounded at base, to 8 in. long: fls. 5^in. long, in cymes; petals and 

 stamens usually 6. Afr., S. and E. Asia. B.R. 24:61. E.P. IV.

 petals 10. India. E.P. IV. 2206. 10. A. platanifblium. Harms 

 (Marlea platanifolia, Sieb. &Zucc.). Tree: Ivs. roundish in outline, 3-

 and stamens usually 6. Japan, China, E. P. IV. 2206, p. 23. This 

 seems to be the hardiest species and is probably hardy as far north 

 as Washington, D. C. A -n

ALBERTA (from Albertus Grotus, commonly known 

 as Albertus Magnus, philosopher of the thirteenth 

 century, who wrote concerning plants). Rubidcex. Two 

 species of shrubs or trees, one of which has been intro- 

 duced as a hothouse or greenhouse subject. 



Leaves thick, opposite: fls. rose-colored or purplish, 

 in terminal panicles; calyx 10-ribbed and 5-lobed, often 

 colored in fr. ; corolla elongated-tubular. 



magna, E. Mey. Bark pale, the young branches 

 reddish brown: Ivs. 4-5 in. long, obovate-oblong, 

 obtuse, entire, narrowed into a short, stout petiole; 

 midrib stout: panicle terminal, erect, 6 in. high and 

 nearly as broad at the base; corolla-tube 1 in. long, 

 slightly swelling in upper part, pubescent; lobes 5, small, 

 triangular, recurved. Natal. B.M. 7454. G.C. Ill 

 22:416. Gn. 53:430. The other species is A. minor, 

 Baill., from Madagascar. L H B 



ALBfZZIA (after Albizzi, an Italian naturalist). 

 Leguminbsse. Ornamental woody plants chiefly grown 

 for their handsome foliage and also for their attractive 

 flowers; some are valuable timber trees; closely allied 

 to the acacias. 



Trees or shrubs: Ivs. deciduous, alternate, bipinnate; 

 Ifts. usually small and numerous, oblique: fls. in axil- 

 lary, peduncled spikes or globular heads; calyx tubular 

 or campanulate, 5-toothed; corolla small, funnelform, 

 with the segm. connate more than one-half; stamens 

 numerous, more or less connate at the base, exserted: fr. 

 a large strap-shaped pod without pulp. About 25 spe- 

 cies in tropical and subtropical regions of Asia, Afr. and 

 Austral.: 1 in Mex. 



The albizzias arc unarmed trees or shrubs with grace- 

 ful feathery foliage and yellowish, white or pink flow- 

 ers in summer. Most of the species can be grown only 

 in subtropical and tropical regions except A. Julibris- 

 sin which is the hardiest species and can be grown as 

 far north as Washington, D. C. A. lophantha is some- 

 times grown as a greenhouse shrub. 



For cultivation, see Acacia.
