JACABANDA (Brazilian name). BignoniiUece. J. 

 ovalifolia perhaps ranks among the 100 best flowering 

 trees or shrubs for subtropical regions. The foliage is 

 as finely cut as a fern, .symmetrical and elegant. The 

 leaves are decussate, distant, each one with IG or more 

 pairs of pinnse, each pinna having 14-24 pairs of leaf- 

 lets. The plant bears loose, pyramidal panicles, 8 in. high, 

 of 40-90 blue fls., each 2 in. long and VA in. wide, which 

 have a long, bent, swelling tube and the 2 lobes of one 

 lip smaller than the 3 other lobes. Prom S. Fla. It is 

 one of the best of foliage plants for the S., valuable 

 alike for florists' decorations, conservatory, subtropical 

 bedding in the North, or for lawn specimens in Florida, 

 where, if cut back by frost, it rapidly recovers its beauty. 

 It reaches a height of 20 ft. or more. It is commonly 

 planted in parts of S. Calif., and attains a height of 50 

 ft. and more. This species is also cult, in Europe under 

 glass. Jacarandaisa genusof about 30 tropical American 

 spacies, mostly Brazilian: trees, with Ivs. opposite, 2- 

 pinnate, rarely 1-pinnate: Ifts. usually numerous, en- 

 tire or dentate: fls. showy blue or violet, panicled ; 

 corolla lobes rotund; perfect stamens 4, didynamous; 

 staminode about as long as the stamens, club-shaped at 

 the apex and often bearded at the top.

JACOBtNIA (probably a personal name). Acnnthd- 

 ce(v, A polymorphous genus of 30 or 40 tropical 

 American herbs or shrubs, including the genera Libonia, 

 Sericographis and Cyrtanthera. Plants cultivated for 

 their narrow-tubular red, orange or yellow fls. : lvs. op- 

 posite and entire: calyx deeply 5-parted, with linear or 

 awl-shaped segments; corolla more or less 2-lipped, 

 one lip 2-1 ibed and the other 3-lobed; stamens 2; stami- 

 nodia represented by two hairy elevations on the corolla 

 tube; pistil ripening into an oblong or ovate capsule, 

 the style filiform, the ovary surrounded by a disk. 



Jacobinias, in common with other Acanthads, are 

 much confused as to species. A closely allied genus is 

 Justioia, which, among other characters, is distinguished 

 by having spurs or appendages at the base of the an- 

 ther lobes, whereas Jacobinia has no such appendages. 

 Other allied genera are Aphelandra, Dianthera, Ad- 

 hatoda, Thyrsacanthus, Eranthemum, Barleria, Dfeda- 

 lacanthus. 



Jacobinias are mostly subshrubs in their native places, 

 but they are usually treated as herbs under cultivation. 

 They are showy greenhouse or conservatory subjects. 

 When well grown they are attractive plants, but they 

 soon become weedy under neglect. They propagate very 

 readily from cuttings, after the m.inner of fuchsias, 

 and the most satisfactory plants are usually those which 

 are allowed to bloom but once. Most of them thrive well 

 under conditions suited to begonias. 



A. Fls. in a more or less dense terminal panicle or 

 Ihyrse: corolla long, more or less curved, sta- 

 mens fixed to the middle or near the fop of co- 

 rolla tiibe. (Subgenus Cyrtanthera.) 



magrnifica, Benth. & Hook. {Cyrtanthera magnifica, 

 Nees. Jnstieia magnifica, Pob\). Strong forking herb 

 or subshrub, blooming when 1 or 2 ft. high, but becom- 



ing several feet high if allowed to grow: stems 4-an- 

 gled : lvs. opposite, lanceolate to ovate-lanceolate to 

 oval-oblong, narrow or broad at base, attenu:ite to apex, 

 wavy-margined, veiny, downy, sometimes a foot long: 

 fls. rose-purple, ascending, arched at the top and the 

 lower lip recurving, borne in den.se terminal spike-like 

 thvrses. Brazil. G.P. 5:317. Var. carnea {Justicia 

 cdrnea, Hook.) has flesh-colored fls. B.M. 3383. B.R. 

 17:1397. — A handsome old plant, of comparatively easy 

 culture in a conservatory temperature. Cuttings made 

 in Feb. or March should bloom early the following 

 winter. Young plants are usually most satisfactory, the 

 old ones being kept over only for cutting stock. Give 

 rich soil, and plenty of water in the growing season. 



Pohliina, Benth. & Hook. (Cyrtanthera Pohlidna, 

 Nees). Much like J. magnifica, but more robust and 

 leafy: lvs. ovate-acuminate and rounded or nearly or 

 quite cordate at the base, more glabrous, often purple- 

 tinged : fls. bright crimson : bracts short-acute, or in 

 one form obtuse. Brazil. — Voss considers J. magnifica, 

 var. carnea to be synonymous with J. Pohliana. 



Var. velitina, Hort. (J. veliitina and Jnstieia velii-- 

 tina, Hort. Cyrtanthera PohliAna, var veliitina, 

 Nees). Dwarf: bracts obtuse : lvs. villous-pubescent 

 on both surfaces : fls 2 in. long, rose-color. Brazil. 

 Gng. 7:212. A.P 14:998. -A worthy plant of compara- 

 tively recent introduction in this country. It is an ex- 

 cellent pot subject and has been considerably adver- 

 tised recently as the "New Dwarf Jnstieiavelntina." A 

 profuse and continuous bloomer. Cultural remarks un- 

 der J. magnifica also apply to this. 



AA. Pis. in a dense terminal spike: corolla long and 

 curved: stamens fixed to the base of the tube, 

 (Subgenus Pohjstaehys.) 



coccinea, Hiern. {Justicia coccinea, Aubl. ). Erect 

 herb or subshrub, usually grown from cuttings each 

 year and treated as a pot subject: 2-5 ft. high: branches 

 terete: lvs. elliptic or ovate-lanceolate, entire, glabrous
