AZARA (I N Azara a Spanish promoter of science 

 especially of botany) BiJcdcee Shrubs or small trees 

 lvs. evergreen, alternate, with usually enlarged and leaf- 

 like stipules : fls. small, in axillary peduncled racemes 

 or clusters, apetalous ; sepals 4-5 ; stamens numerous, 

 rarely 5 : fr. a many-seeded berry. ,\bout 20 species 

 in S. America, especially Chilr. ilan<is,.iiiu evergreen 

 shrubs, with small but frairra'it rU.. I'mi- wanu temperate 

 regions; probably only A. nn, rai.lnjlhi will thrive far- 

 ther north in a sheltered i)o,sitiMH and protected during 

 the winter. Grow best in a sandy compost of loam .and 

 leaf soil. Prop, by seeds or cuttings of mature wood 

 in autumn, placed in slight bottom heat under glass.

 rate, or nearly entire, %-%\n. long, shining, glabrous, 

 the stipules similar, but half the size : fls. greenish, in 

 few-fld. clusters; stamens 5: berries orange. Feb., Mar. 

 Chile. G.C. II. 1: 81. — Graceful evergreen shrub, regu- 

 larly pinnately branched, excellent for covering walls ; 

 the hardiest of all the cultivated species.

AZ6LLA (Greek, (0 destroy bij drying). Salviniaceo'. 

 A small genus of floating aquatics with small, pinnate 

 stems and minute fleshy 2-lobed lvs., producing two 

 sorts of spores in globular sporocirps. The species mul- 

 tiply rapidly by self-division, but will grow readily in 

 water containing a little nutriment. The species are 

 distinguishable only by microscropic examination.
