ACACIA, FALSE: Robinia Pseudacada. 

 ACACIA, ROSE: Robinia hispida. 



from Greek word signifying thorn). Ros&cex. 

 NEW ZEALAND BUR. Trailing, more or less evergreen 

 plants used in rockwork and as ground cover under 

 trees and between other plants. 



About 40 species of sub-shrubs or herbs of the south- 

 ern hemisphere, allied to Agrimonia and Sanguisorba: 

 Ivs. unequally pinnate, alternate, the Ifts. toothed or 

 cut: fls. small, crowded in erect terminal spikes or 

 heads; petals none; calyx 5-7-lobed, usually armed 



77. Acalypha hispida (A. Sanderi). 



with spines; stamens 1-10, or even more: fr. an achene, 

 1 or 2 being enclosed in the hardened calyx. 



Acaenas are little grown in this country, but un- 

 prized in England as groundwork for dwarf spring- 

 flowering bulbs, as trilliums; also useful in protecting 

 native orchids and bog plants. Propagation is by cut- 

 tings, divisions and seeds. 



Buchfinanii, Hook. f. Plant usually densely or silky 

 pale gray, the numerous sts. and branches lying very 

 close on the ground: Ivs. 1 in. or less long, the Ifts. 

 3-6 pairs, very broad, finely serrate: fls. in small sessile 

 heads; spines or bristles 4, yellow and hairy or barbed, 

 the fruiting calyx broader than long. New. Zeal. 



microphylla, Hook. f. Plant glabrous or only 

 sparingly silky, often making very large patches: Ivs. 

 pale, 2 in. or less long; Ifts. 3-6 pairs, broad, deeply cut: 

 fls. in globose stalked heads; fruiting calyx broader than 

 long, the red spines attractive all summer and autumn. 

 New Zeal. Grows well in either wet or dry soils. Var. 

 inermis, Kirk (A. inermis, Hook, f.), has longer Ivs. 

 and the fruiting calyx without spines or bristles. 



ovalifolia, Ruiz & Pav. Lvs. a little larger than the 

 last; Ifts. oblong, subcuneate. Chile. On. oz, p. to. 



adscendens, Vahl. Plant usually glabrous bronzy, 

 the sts. stout and nmstrate, the leafy branches ascending 

 at the tips: Ivs. 2-4 in. long: Ifts. 4-6 pairs, ovate or 

 obovate, deeply toothed: fls. in stalked heads; calyx- 

 tube longer than broad, the spines 4 and stout. New 

 Zeal., S. Amer. Apparently the plant in the trade 

 under the name of A. adsurgens. 



A. argtntea, Ruiz & Pay. Lvs. silvery. Chilean Andes. A. 

 myriophylla, Lindl. Fern-like: Ifts. deeply cut: fls. green, Chile. 

 A. novse-zealandix , Kirk. Prostrate, silky: Ifts. oblong, coarsely 

 serrate: heads globose, stalked: bristles reddish purple: achene nar- 

 rowed both ways. New Zeal. A. ovina, A. Cunn. Said to be much 

 like A. ovalifolia, but larger and less graceful: fls. purple, in long 

 spikes. Austral. A. Sanguisdrbx, Vahl. Prostrate, silky: Ifts. 

 broad, toothed or serrate: heads globose, stalked; bristles long and 

 barked, at each angle of calyx: achene broadest near base and nar- 

 rowing upward; one of the troublesome sheep-burs. New Zeal. A. 

 sarmenldsa, Carmich.=A. Sanguisorbffi. T H R 



ACALYPHA (a name given by Hippocrates to a 

 nettle). Euphorbmcese. COPPER-LEAF. THREE-SEEDED 

 MERCURY. Brilliant tender foliage shrubs or herbs 

 much used for greenhouse ornament, and especially for 

 bedding-out; and in Florida and southward for lawn 

 shrubs and hedges. 



The acalyphas are erect shrubs or, in the native 

 species, rather weedy herbs, with alternate stipulate 

 Ivs: fls. in spikes or spike-like racemes, the staminate 

 cluster peduncled, each fl. in the axil of a minute 

 bractlet, with a 4-parted calyx and 8-16 stamens; 

 pistillate fls. subtended by a foliaceous bractlet, the 

 calyx 3-5 parted; petals wanting in both kinds of fls., 

 the long spike-like ament being the showy part of the 

 fls.: fr. usually of 3-2-valved carpels, each 1-seeded. 



For bedding, it is desirable to have strong, well- 

 hardened plants in 4-inch pots, which should be set out 

 the last week in May, and grown in a rich, moist soil 

 without check. The leading horticultural species is 

 A. hispida. The main point in the cultivation of this 

 species is that it can be grown either to a single stem 

 or in a spreading bush form, both of which ways are 

 effective. Stock plants of acalypha do well in a mixture 

 of three parts loam, one part well-decomposed manure, 

 and, if the loam is heavy, also some sharp sand. In 

 central Florida, none of the acalyphas is quite hardy. 

 They should be banked late in the fall with dry sand, 

 which must be removed when all danger of frost is over. 



Propagation is 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 several beside the
