JACABANDA (Brazilian name). Bignoniacece. J. 



lUfoUa perhaps ranks among the 100 best flowering 



:es or shrubs for subtropical regions. The foliage is 



finely cut as a fern, symmetrical and elegant. The 



ives are decussate, distant, each one with 16 or more 



irs of pinnae, each pinna having 14-24 pairs of leaf- 



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



40-90 blue fls., each 2 in. long and 1% in. wide, which 



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



:> smaller than the 3 other lobes. From S. Fla. It is 



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



ike for florists' decorations, conservatory, subtropical 



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



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



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



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



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



ass. Jacarandaisa genus of about 30 tropical American 



a.cies,' mostly Brazilian: trees, with Ivs. opposite, 2- 



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



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



rolla lobes rotund; perfect stamens 4, didynamous; 



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



, e apex and often bearded at the top.

JACOBlNIA (probably a personal name). Acanthd- 

 (V. A polymorphous genus of 30 or 40 tropical 



' merican herbs or shrubs, including the genera Libonia, 

 ericographis and Cyrtanthera. Plants cultivated for 

 leir narrow-tubular red, orange or yellow fls. : Ivs. op- 

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



'vvl-shaped segments; corolla more or less 2-lipped, 

 ae lip 2-lobed and the other 3-lobed; stamens 2; stami- 

 odia represented by two hairy elevations on the corolla 

 ibe; pistil ripening into an oblong or ovate capsule, 

 le style filiform, the ovary surrounded by a disk. 

 Jacobinias, in common with other Acanthads, are 

 mch confused as to species. A closely allied genus is 



'usticia, which, among other characters, is distinguished 

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

 ler lobes, whereas Jacobinia has no such appendages. 

 >ther allied genera are Aphelandra Dianthera, Ad- 

 atoda, Thyrsacanthus, Eranthemum, Barleria, Dceda- 

 icanthus. 



Jacobinias are mostly subshrubs in their native places, 

 ut they are usually treated as herbs under cultivation, 

 ^ey are showy greenhouse or conservatory subjects. 

 Vhen well grown they are attractive plants, but they 



'oon become weedy under neglect. They propagate very 

 eadily from cuttings, after the manner of fuchsias, 

 nd the most satisfactory plants are usually those which 

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



inder conditions suited to begonias. 



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

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

 Hti'HS fixed to the middle or near the top of co- 

 rolla tube. (Subgenus Cyrtanthera.) 



magnifica, Benth. & Hook. (Cyrtanthera magnifica, 

 ^ees. Jnxlicin magnifica, Pohl). Strong forking herb 

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



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

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

 oval-oblong, narrow or broad at base, attenuate 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 dense terminal spike-like 

 thyrses. Brazil. G.F. 5:317. Var. carnea (Justicia 

 camea, 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. 



Pohliana, Benth. & Hook. (Cyrtanthera Pohliana, 

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

 leafy: Ivs. 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. velutina, Hort. (J. velutina and Justicia velu- 

 tina, Hort. Cyrtanthera Pohliana, var velutina, 

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

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

 Gng. 7:212. A.F 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 Justicia velutina. 11 A 

 profuse and continuous bloomer. Cultural remarks un- 

 der J. magnifica also apply to this. 



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

 curved : stamens fixed to the base of the tube. 

 (Subgenus Polystachys.) 



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: Ivs. elliptic or ovate-lanceolate, entire, glabrous 



1190. Jacobinia Penrhosiensis (X 



or nearly so : fls. crimson, in a dense terminal spike, 

 pubescent, the long upper lip more or less arched and 

 the lower one reflexed. Brazil. B.M. 432. -Blooms in 

 summer. Said to be known sometimes as Aphelandra 

 cristata.
