AC^NA (from akaina, thorn). Bosd.L'€CP. Dwarf, 

 hardy perennial sub-shrubs with inconspicuous green 

 flowers, cultivated in rockeries for their showy crimson 

 spines, which are borne on the calyx; 1-12 in. As ground- 

 work for dwarf, spring-flowering bulbs, as trilliunis, they 

 are unsurpassed. Useful in protectini^ iiativi- orcliids and 

 bog plants. Prop, by eiittings, crnpiiii^ ntutlits, divi- 

 sions and seeds. Monogr. by T. Citcriif, in Kevue des 

 Sciences Natun-lb-s de I'Ouest, 1871, Nos. l,2/S.

ACAL'^'FHA (a name given by Hippocrates to a net- 

 tle). Euphorbidcece . Tender foliage plants miich used 

 for greenhouse ornament, and especially for bedding- 

 out. For the lattiT ]iurpost_: itis desirable to have strong, 

 well hardene<l jtlanls in .')-in. pots, which should be set 

 out the last week in ^May, and grown in a rich soil with- 

 out check. Prop, by cuttings, chiefly in three ways: 

 (1) in fall from outdoor bedded plants ; (2) from plants 

 lifted in fall, cut back, and kept for spring stock ; 

 ( 3 ) from stock plants in pots reserved from the 

 previous season. The well ripened wood of these 

 last is a great advantage, and gives cuttings that may

be taken with a heel. A mature stem will furnish sev- 

 eral beside the top one. This is the best method for gen- 

 eral purposes. Cuttings are taken below joints, and re- 

 quire mild bottom heat. For greenhouse ornament in fall 

 and winter, excellent specimens may be secured from 

 cuttings made in summer from such stock plants.

 compost of loam and leaf-mold. Being natives of the 

 hottest, moist, densely shaded jungles, they require much 

 heat and moisture during the growing period. Good 

 drainage is essential. Prop, by dividing the pseudobulbs 

 as soon as growth begins. Cult, by E. O. Orpet,

 evergreen perennials; dwarf, tufted, with sharp-pointed, 

 rigid leaves; less common than Stiitice and Armeria. An 

 oriental genus of slow-growing and snn-loving plants for 

 rockeries. Prop.by seeds (which germinate slowly) sown 

 carefully on a warm but somewhat shaded border, and 

 transplanted when plants are large enough to handle; by 

 cuttings made in late summer and wintered in a frame; 

 by very carefully made divisions. Boissier describes 74 

 species in the Flora Orientalis. See A. Bunge, Die Gat-

ACANTHOMINTHA. Lahidhe. Thorny Mint. Ten-
