 thin and membranous: fls. white in many-fld. panicled 

 racemes. New Zeal. — Cult, somewhat in S. Calif.

 dentate, smooth, shining, oblong and acute at the apex: 

 fls. inconspicuous, greenish, axillary. Chile. — Grown

ARMENiACA: Prunus. 



ARMERIA (an old Latin name). Plumhaginacex. 

 Se-^ Pink. Thrift. Small perennial herbs, with ro- 

 settes of narrow evergreen leaves on the ground, planted 

 along borders and walks, used for continuous low 

 edgings and in rock-gardens; sometimes grown as 

 pot-plants. 



Scape naked, simple, 2-12 in. high, on which is borne 

 a compact head of pink, hlac or white fls., the head 

 being subtended by small bracts, forming a kind of 

 involucre; fls. with plaited funnel-shaped dry caly.x, the 

 lobes pointed; 5 petals nearly or quite distinct and 

 tapering at the base; 5 stamens opposite the corolla 

 parts; styles 5, hairy below the middle: fr. a utricle 

 inclosed in the calyx. — About 50 species in Eu., W. Asia, 

 N. Afr. and 1 in N. Amer., much confused. 



Armerias are of easiest culture, being hardy and free 

 growers. Propagation is by division of the stools; also 

 by seeds.

380. Armeria vulgaris. iXH) 



Blooms in spring. In full sun 

 or in rather dry ground, it is difficult to keep this charm- 

 ing plant in a healthy condition; partial shade is essen- 

 tial to its welfare. One can grow luxuriant specimens 

 on the northern slope of a rockery or close to a building 

 on the east or north side. Prop, by seeds, division, or 

 by root-cuttings.
