STHI0N£HA (aitho, scorch, and nema, filament; 



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 cut with longer an<I straighter stems. Prop, by 

 seeds in spring or by cuttings in summer ; annual and 

 biennial kinds by seeds. j. b. Keller.

 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. pulchUlum 

 was sold under this name for many years. 



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

 lvs. usually longer than in A. coridifolium, more linear

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

 the sepals. Persia. Gn. 9:5.

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

AOALM'^LA {agalma, ornament, and hule, wood; an 

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

 nerdcea. Tender climbers from Java, which may be 

 grown in a basket like .SIschynanthus.

AGAPANTHUS 



AOANtSIA (Greek oyaKos, 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. 



pulch^lla, 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. Thereareoor6others. A.cterulea.Heichh.t. 

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

 —A. cydnea, Benth. & Hook, (not Reichb., which = Acacaulis 

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

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

 Lindl. (see Rolfe., G.C. III. 6. p. 492). 



AGAPANTHUS (agape, love, andanthos, flower). Jyil- 

 idcem. Conservatory plants, with tuberous rootstocks, 

 tall simple scape, and 2-bracted vunbel 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 lvs. 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 summer 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. 





44. Agapanthus umbellatus. 



scape rising 2-3 ft. from the leaf -rosette, bearing an um- 

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

 with a short tube. Cape of Good Hope. B.M. 500. - One 

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

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

 biduB); dwarfs, as var. miiior and var. MooreAnus, both 

 with blue fls. ; giant forms, as var. m4ximuB ( both blue
