JACARANDA {Brazilian name). Bignoniacea'. J. 

 ocalifoUa perhaps ranks among the 100 best tlowering 

 trees or shrubs for subtropical regions. The foliage is 

 as tinely cut as a fern, symmetrical and eleLrant. The 

 leaves are decussate, distant, each one with 10 or more 

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

 lets. Thepiantbearsloose.pyramidalpanicles.Sin. hiijh, 

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

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

 lip smaller than the 3 other lobes. From 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 cutback 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. Jacarandais a genus of about 30 tropical American 

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

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

 tire or dentate: tls, sbowy blue or violet, panicle<l ; 

 corolla lobes rotund; perfect stamens 4, didynamons; 

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

 the apes and often bearded at the top.

JACOBtNIA (probably a personal name). Acantlt.'i- 

 rt'ff. A polymorphous genus of 30 or 40 tropical 

 American herbs or shrubs, ineludina: the genera Libonia. 

 Sericographis and Cyrtanthera. Plants cultivated fi-r 

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

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

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

 one lip 2-l:)bed and the other 3-lobed; stamens2; 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 

 Justicia, 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, Erauthemum, Barleria, D^da- 

 lacanthus. 



Jacobinias are mostly subsbrubs 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 manner 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 teruihial payiicJe or 

 thtfrse : coroUa long, vwre or less curved, std- 

 tn'yns fixed to the middle or )it'ar the top of co- 

 rolla tube. {Subgenus Cyrtanthera.) 



magnifica, Benth. 6c Hook. [Cyrtanthera magnifica, 

 Nees. Justicia magnifica, Yoh\). Strong forking herb 

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



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

 K'led : lvs. opposite, lanceolate to ovate-lanceolate to 

 oval-oblong, narrow or broad at base, attenuate to apes, 

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

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

 lower lip recurving, borne in dense terminal spike-like 

 thvrses. Brazil. G.F. 5:317. Var. cornea (Ju.'^ticin 

 c>irne<i, Kook.) has flesh-colored tls. B.M. 3383. B.R. 

 17:131*7. — A handsome old plant, of comparatively easy 

 culture in a conservatory temperature. Cuttiui^s 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. 



Pohliana, Benth. & Hook. (Cyrfanlhtra PidiUilna, 

 Xeesi. Much like J. mag)iifica,h\it more robust and 

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

 quite cordate at the base, more e:labrous, often purple- 

 tinji'ed : fls. bright crimson : bracts short-acute, or in 

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

 var. cornea, to be synonymou.s with J. Pohliana.

 tised recently as the "New Dwarf Justicia v< lutina.'' A 

 profuse and continuous bloomer. Cultural remarks un- 

 der J. inaguifico also apply to this.
