^THION^MA (aitho, scorch, and nema, filament; 

 probably referring to appearance of stamens). Crucif- 

 erm. Dwarf shrubs for the hardy herbaceous border or 

 rockery. Less common than Iberis. The genus differs 

 from Iberis in having all its petals equal, and from Le- 

 pidium in having its four stamens longer, winged and 

 toothed. Fls. various shades of pink and purple. W. B. 

 Hemsley, in Gn. 9, pp. 108, 109. 



They dislike a moist or stiff soil or shady places ; but 

 in light, sandy loam, on dry and sunny slopes, they are 

 compact and branchy, and when once fairly established 

 will last for many successive years without replanting or 

 renewal, while under the opposite conditions the plants 

 grow feeble and lanky, and may die after a year or two. 

 They keep fully as well as the Candytufts in water, and 

 can be out with longer and straighter stems. Prop, by 

 seeds in spring or by cuttings in summer ; annual and 

 biennial kinds by seeds. j. g. Keller. 



coridifdlium, DC. [Ihlris juciinda, Schott & Kotschy). 

 Branches numerous, thick, 4-6 in. high : Ivs. crowded, 

 short, nerveless, linear or linear-oblong, acute or obtuse : 

 fls. smaller and later than in the next, in dense, short, 

 rounded racemes. Chalky summits of Lebanon and 

 Taurus. B.M. 5952. — Good for edging. A. pulchMlum 

 was sold under this name for many years. 



grandifldrum, Boiss. & Hohen. Branches 1-lK ft. : 

 Ivs. usually longer than in A. coridi folium, more linear 

 and more acute: fls. as large as those of Arabis alpina, 

 in slender, elongated racemes ; petals 4 times as long as 

 the sepals. Persia. Gn. 9:5. 



P^rsicum, Hort. Stout, erect, shrubby, dwarf. Fls. 

 deep rose. Best of dwarfs. Int. 1892, by J.W. Manning. 



pnlch^llum, Boiss. & Huet. Similar to A. eoridifolium, 

 but more diffuse and trailing. Fls. smaller and brighter- 

 colored; petals 2% times as long as the sepals. Persia.

AGALM'i'LA (agalma, ornament, and hule, wood; an 

 ornament to the woods in which they grow wild). 6es- 

 nerdcece. Tender climbers from Java, which may be 

 grown in a basket like .Slsohynanthus. 



A . longistyla, Oarr. , is considered a synonym of the next. R.H. 

 1873: 270.— A. statninea, Bltime. St. rooting from the lower sur- 

 face: Ivs. alternate, with an abortive one opposite the base of 

 each ; petioles 4-8 in. long ; blade as long, ovate, serrate : fls. in 

 largeaxillary sessile fascicles of 12-14; stamens exserted. B.M.

AGANlSIA (Greek aganos, desirable). A small genus 

 of tropical American epiphytal orchids, little cult, in N. 

 Amer. Botanically allied to Warrea and Zygopetalum. 

 Need a humid atmosphere. Grown on blocks in high 

 temp. Prop, by dividing pseudobulbs. 



tricolor, N. E. Brown. Fls. in a raceme; sepals whit- 

 ish ; petals light blue ; lip in the form of a saddle, marked 

 with orange-brown. S.Amer. 



pulchfilla, Lindl. Fls. white, blotched yellow on the 

 lip, in a racemose spike from the base of the bulb. 

 S. Amer. 



The above species are the only ones known to have been offered 

 In the Amer. trade. There are 5 or 6 others. A.cteniiea, Reiehb. f. 

 Fls. in axillary peduncles, blue-blotched, the lip bristled. Braz. 

 —A. cydnea, Benth. & Hook, (not Reicbb., which = Acacaulia 

 cyanea) . Much like A. tricolor, the lip blue and undulate at the 

 tip. B.R. 1845; 28, as Warrea cinerea, Lindl.; also, W. cyanea, 

 Lindl. (see Eolfe., G.C. HI. 6, p. 492). 



AGAPANTHUS (ajrapc, love, and aniftos, flower). Zil- 

 idcece. Conservatory plants, with tuberous rootstocks, 

 tall simple scape, and 2-bracted umbel of handsome fls. : 

 perianth with 6 wide-spreading divisions, nearly regu- 

 lar: pod many-seeded; seeds flat, winged above : foliage 

 evergreen. 



In this country, Agapanthuses are usually grown in 

 tubs (the roots are apt to burst pots), and are flowered 

 in late spring or early summer in the conservatory, win- 

 dow garden, or living room. The plant is kept dormant 

 during winter, as in a frame or light cellar, only enough 

 life being maintained to prevent the Ivs. from falling (the 

 var.albidus usually loses its leaves). When in bloom, 

 give abundance of water. Plants will bloom many years 

 if given a large enough tub, not allowed to become over- 

 crowded in the tub, and supplied with manure water, 

 sending up many clusters each year. Good results can 

 also be obtained in single pots. It forces well. If kept 

 dormant until spring, they may be bedded in the open, 

 or massed in vases, for sunomer bloom. Prop, by divid- 

 ing the roots (and rarely by seeds). Old roots break up 

 more easily if soaked in water a few hours. When dor- 

 mant, the plant will stand a few degrees— usually 10° or 

 less— of frost.

 bel of 20-50 handsome blue fls. ; perianth funnel-shaped,

 of the best known of half-hardy liliaceous plants. There 

 are white-flowered varieties (the best known is var. 41-

 with blue fls. ; giant forms, as var. m&zimus (both blue
