 cordate, 3-5 cuspidate or lobed. S. China. — Yields an

 deep-rooted perennial forage plant of the Leguminbsw.

 Willi :; ,.\ lit, .'liloiig toothed leaflets, and small head-like 

 r;ic, 111. s (if jMM pie clover-shaped fls. It is native to Eu. 

 lu lln- arid iiarts of the U.S. it is the staple hay and 

 foraire iilaut, and it is also grown to a considerable ex- 

 tent in the E. Two to sis mowings may be made each 

 year from established meadows. Fifteen to 20 lbs. of 

 seed are sown to the acre; and the seed is preferably 

 sown alone, without another crop. Alfalfa should not be 

 pastured the first year. In two or three years it be- 

 comes thoroughly established and productive, and it 

 should continue for many years. June grass often runs 

 it out in a cool, moist climate. Alfalfa often becomes 

 a weed in waste places. 



ALFILfiRIA. The West American or Spanish name 

 for A'rddiiim ricutdrium, L'Her. GeraniAcea. A hairy 

 annual which is used for pasture in dry regions. 



Alga, plural AL&S:. a general name for chloro- 

 phyll-bearing thallophytes. They are flowerless plants, 

 allied to the fungi, and generally inhabit water. Those 

 occurring in salt water are known as seaweeds. None 

 are cultivated. The green "moss" on flower-pots is made 

 up of alga?. 



ALGAROBA is the fruit of Ceratonia siliqtia 



ALHAGI (its Mauritanian name). Legw-min&sm. Low, 

 spiny, much branched shrubs: lvs. oblong, small, ob- 

 tuse, entire, alternate : fls. papilionaceous, in few-fld. 

 racemes. Summer. Three closely allied species from 

 Greece and Egypt to Himalayas, producing the Persian 

 or Alhagi Manna. They may be cult, in temperate re- 

 gions in dry and sunny positions and prop, by seeds and 

 greenwood cuttings under glass with a little bottom 

 heat.

ALLAMANDA(Dr. Allamand, Leyden). ApocynAcea. 

 Greenhouse shrubs, mostly climbers. Lvs. entire, 

 whorled: fls. terminal, large and funnel-shaped, with a 

 flat-spreading or reflexed limb, the tube inflated below 

 the throat: ovary 1-locuIed: stamens 5, the filaments 

 very short. 



Allamandas are of easy culture. They are usually 

 grown in the gi-ound or in large tubs, and trained on the 

 rafters. For best results, they should have plenty of 

 sun. The bushy kinds, as 4. «cn;7i)Zia, A. grandiflora 

 and A. WilUamsi, may be grown as specimen plants 

 in pots. The strong kinds, as A. Schottii, are some- 

 times used as stocks upon which to graft the weaker 

 ones, particularly if root plants are desired. Prop, by 

 cuttings of growing wood in a bottom heat of 75° ; also 

 by layers. The species are much confused.

 neriildlia, Hook. A stocky, bushy grower, useful for

 against a support if allowed to take its full course : lvs. 

 iu 3's-5's, glabrous, oblong or elliptic, acuminate : co-

Schbttii, Pohl. Strong-growing, suitable for rafters: 

 young shoots and petioles slightly pubescent, the older 

 stems warty: lvs. in 3's or 4's, broadly lanceolate and 

 acuminate: corolla large, rich yellow, the throat darker 

 and beautifully striped. Braz. B.M. 4351, but this por- 

 trait is considered by Index Kewensis to belong to A. 

 cathartica. A.magnifica, introduced into the U. S. in 

 1893, is probably a form of this species.
