ACHLYS 



ACONITUM 



ACHLYS (the goddess of obscurity). Berberidacece. 

 Hardy herbaceous perennial. Fls. minute, numerous, 

 spicate, on a slender scape. 



triph^lla, DC. Root-stock terminated by a strong, 

 scaly winter-bud : Ivs. 1 or 2 ; leaflets 3, fan-shaped, 

 sinuate-dentate, 2% x5 in.: scape 1 ft. long, spike 1 in. 

 long. Spring. W. N. Amer. An interesting and deli- 

 cate plant. Int. 1881. 



ACHRAS. See SajwJillo. 

 ACHYRANTHES. See Iresine. 



ACID ANTHERA (pointed anthers). Iridacece. Ten- 

 der herbaceous perennials, intermediate between Gladio- 

 lus and Ixia. Lvs. many, linear ensiform, 1-1 %ft. long: 

 spikes 3-6-flowered, simple, lax : fls. long-tubed, some- 

 what pendulous : conns roundish, flattened, covered with 

 a matted fiber. Prop, by seed or by the numerous conns. 



bicolor, Hochst. St. 15-18 in.: fls. creamy white, 

 blotched chocolate brown within, fragrant : corms K-l 

 in. in diam. Abyssinia. G.F. 1:486, 487. Gn. 47:1014. 

 G.C. III. 20:393. Mn. 8: 11. Requires a somewhat 

 stiffer soil than the tender species of Gladiolus. May be 

 grown in a tub outdoors during summer, and flowered 

 within during Oct. Several corms in a large pot give 

 good results. Corms should be dried as soon as lifted, 

 to prevent rot. 



A. cequinoctialis, Baker. St. 3-4 ft., stout, stiffly erect: Ivs. 

 strongly ribbed: fls. white, blotched crimson or purple within: 

 corms large. Sierra Leone. B.M. 7393. May be a stronger 

 growing and more tropical form of the above.

ACINETA (immovable, the lip being jointless). Orchi- 

 dacece. Stout epiphytes with interesting pendent scapes. 

 Pseudobulbs conspicuously furrowed, slightly com- 

 pressed : leaf -blades smooth, conspicuously veined, 

 plaited and pliable : fls. globose. As a genus it is too 

 near to Peristeria and Stanhopea. The species are 

 rarely seen, as they are less conspicuous in their color- 

 ing than many orchids. They require a warm house and 

 plenty of moisture during the growing season, with a 

 decided rest, to make them flower. Use baskets, not pots, 

 as the flower-spikes are produced from the base of the 

 bulbs, as in Stanhopea, and should have free egress or 

 they will be lost. Cult, by E. O. ORPET. 



Barker!, Lindl. (Peristeria Bdrkeri, Batem.). Pseu- 

 dobulbs sub-conic, about 5 in. : leaf -blades longer than 

 in A. Humboldtii : fls. 12 or more, in pendent racemes, 

 golden yellow spotted with brown. Mex. B.M. 4203. I.H. 

 2: 44. Gn. 54, p. 332. P.M. 14:145.

 leaf -blades about 1 ft. long, lanceolate, acute: scapes 

 pendent, 2 ft. long ; fls. 6 or more, chocolate colored, 

 about 2 in. in diam. Ecuador, high elevations. Gn. 

 3:11. 



A. chrysdntha, Lindl. Racemes pendent; fls. golden yellow, 

 with whitish labellum and crimson or purplish column ; label - 

 lum furnished with a long, blunt, papillose horn. Mex. A. 

 densa, Lindl. (A. Warscewiczii, Klotzsch). Fls. subglobose, fra- 

 grant, pale yellow, spotted externally with reddish brown ; label- 

 lum yellow, spotted with reddish brown. Costa Rica. A.Hru- 

 bydna, Reichb. f . Fls. ivory white, in loose racemes ; lip spotted 

 purple,with erect side lobes. New Grenada. A . sulcata, Reichb. f . 

 Similar to A. Humboldtii. Fls. yellow. OAKES AMES

 in Fla. and Calif. Fls. with the odor of jasmine, lasting.

 T. Thunbergii, Hort., not Harv.). Lvs. 3-5 in. long, 

 short petiolate, leathery, elliptic, acute, shining above: 

 fls. numerous, in dense axillary, branched, short cymes, 

 pure white, very sweet scented. Natal. B.M. 6359. R.H. 

 1879 : 270. G.F. 6 : 185. G.C. 1872 : 363. - Poisonous. The 

 plants cult, under this name are said by trade catalogues 

 to have pink or violet flowers. 



venenata, G. Don. ( Toxicophlcea cestroldes, DC. T. 

 Thunbergii, Harv., not Hort. ). Fls. white or rose. Dif- 

 fers from the above in the well marked venation of the 

 leaves, its flowers a third smaller, its calyx not pubescent, 

 and its corolla-limb less widely spreading. 



ACONITE, WINTER. See Eranthi*. 



ACONlTUM. Kanunculdcea>. ACONITE. MONKHOOD. 

 WOLFSBANE. A genus of hardy ornamental, perennial 

 herbs, much used in borders, etc. Many species are 

 planted in European gardens, but only nine have been 

 much used in America. The number of species varies. 

 from 18 to 80, with different botanists. Native in moun- 

 tain regions of Europe, temperate Asia, and five in N_ 

 Amer. Root tuberous, turnip-shaped, or thick fibrous : 

 st. tall or long, erect, ascending or trailing : Ivs. pal- 

 mately divided or cleft and cut-lobed: fls. large, irregu- 

 lar, showy ; sepals 5, the large upper sepal in shape of & 

 hood or helmet; petals 2-5, small; stamens numerous; 

 carpels 3-5, sessile, many-ovuled, forming follicles when 

 ripened. The following species do well in any garden 

 soil, but rich preferred; they thrive in open sun, but 

 flowers last longer in shaded places. Aconites should 

 never be planted in or too near the kitchen garden or 

 the children's garden, as the roots and some of the 

 flowers have a deadly poison. Prop, easily by division.
