JACQUINIA

2006. Jacobinja penrhosiensis. 



( X ' 2) 



dense corymb, 2 in. long, golden yellow, on very short 

 pedicels, the bracts hnear-lanceolate and dark green; 

 calyx Jain, long, with long subulate lobes; corolla gla- 

 brous, slightly curved, the upper lip oblong-lanceolate 

 and vaulted, the lower lip oblong and reflexed and 

 3-lobed. Mex. B.M. 5887. Gn. 71, p. 56.3. J.H. III.

 attractive winter-flowering warmhouse subject. 



AA. Fls. scattered or in loose 

 more or less leafy pani- 

 cles; corolla of medium 

 length, straight or 

 nearly so, not deeply 

 cleft. (Subgenera Lih- 

 onia, Sericographis 



pauciflora, Benth. & 

 Hook. (SericSgraphis pauci- 

 flora, Nees. Libdnia flori- 

 bUnda, C. Koch). A com- 

 mon conservatory plant, 

 subshrubby, but 

 usually treated as 

 a pot-plant, with 

 terete, short- 

 jointed, close-pu- 

 bescent branches: 

 Ivs. elliptic or 

 elliptic -oblong, 

 short and rather 

 small, entire, very 

 short-stalked : fls. 

 1 in. long, tubular, 

 drooping, or 

 nearly horizontal, 

 scarlet with yellow at the end, the lips short. Brazil. 

 — A most floriferous plant, almost as easy to grow as a 

 fuchsia, and to be handled in essentially the same way. 



Ghiesbreghtiana, Benth. & Hook. {Cyrtaidh'era 

 Ghiesbreghtiana, Decne. Sericographis Ghiesbreghtiana, 

 Nees. Justicia Ghiesbreghtiana, Lem. Apheldndra 

 Ghiesbreghtiana, Hort.). Lvs. narrower (lance-ovate) 

 and longer, acuminate: fls. in a terminal, very loose 

 panicle, tubular, scarlet, appearing at the same season 

 Sisihos^ oi J . penrhosiensis. Mex. F.S. 4:339. Gt. 98. 

 — Intro, by Ghiesbreght; but when the plant was trans- 

 ferred to the genus Jacobinia the name was mispeUed 

 Ghiesbrechtiana. A good winter bloomer. 



penrhosiensis (Libdnia penrho-nensis, Carr.). Fig. 

 2006. Much like J. pauciflora, but lvs. more pointed 

 and fls. larger and more .showy. R.H. 1876:50. Gng. 

 2:131. — It is an excellent plant, and is taking the place 

 of J. pauciflora. It is a hybrid of J. pauciflora and J. 

 Ghiesbreghtiana. Another and very similar hybrid of the 

 same parentage is Sericobonia ignea, Lindl. & Andre. 

 I. H. 22:198. J. penrhosiensis is a winter bloomer, a 

 little earUer than J. pauciflora. Cuttings struck in 

 spring make full blooming subjects by fall and early, 

 winter. This and J. pauciflora are common conser- 

 vatory plants. 



spicigera (Justicia spicigera, Sehlecht. Justicia 

 atramentaria, Benth. Jtisticia Mohintli, Moc. & Se.sse. 

 Sericographis Mohintli, Nees. Jacobinia Mohintli, 

 Benth. & Hook. Drej'era WiUdcnowidna,Nee!i). I'nder- 

 shrub, erect, pubescent: lvs. long-ovate to lanceolate, 

 thick: fls. 1 in. long, axillary, secund, orange-yellow; 

 coroUa-tube elongated, inflated above, the upper lip 

 somewhat arched, and entire, the lower lip spiral and 

 3-toothed. Mex. — Fls. said by some to be pale purple. 



suberecta, Andr^. Herb, velvety pubescent: sts. 

 prostrate, with erect flowering branches: lvs. opposite, 

 petioled, ovate, obtuse, to 2} 2 in. long: fls. in 1-10- 

 fld. peduncled cymes, the bracts spatulate-obovate and 

 obtuse; calyx-tube short and nearly hemispheric; 

 corolla bright scarlet, the slightly curved tube about 



l}4 in. long, pubescent outside; upper lip slightly 

 emarginate and ovate, the lower 3-toothed and oblong. 

 Uruguay. B.M. 81350. R.H. 1900:210.— Handsome 

 warmhouse plant, suitable for baskets. 



J. Ltndenii, NichoU. (Justicia Lindenii, Houll.), is a Mexican 

 subshrub, with long-ovate opposite decua.sate lvs., and a dense 

 fascicled iiead of orange-yellow fls.: divisions of caly.\ linear; corolla 

 long-tubular. 2 in. or more; 2 stamens attached in lower part of 

 corolla. Does not appear to be in the trade. R.H. 1870:250.

JACQUEMONTIA (after Victor Jacquemont, a 

 French naturalist; died 1832). Convolt'uldcese. Sub- 

 tropical and tropical mostly climbing herbs, grown for 

 the convolvulus-like bloom. 



Allied to Ipoma?a and Convolvulus, to which they 

 are probably inferior for garden cult. They are dis- 

 tinguished from Ipomoca by having 2 stigmas instead 

 of 1; and from Convohoilus by having the stigmas 

 ovate or oblong instead of linear-filiform to subulate. 

 Lvs. entire, or rarely toothed or lobed: fls. not large, 

 blue, white or violet, in either dense clusters or loose 

 racemes, sometimes even solitary; coroUa more or less 

 campanulate, the pUcate limb 5-angled or obscurely 

 5-lobed. — Species 60-70 in Trop. Amer. and as far 

 north as S. C., also 1 in Trop. Afr. and 1 in Hawaii. 



J acquemoidia pentaniha makes an attractive green- 

 house climber for summer and autumn flowering, but is 

 not so desirable for this purpose as several species of 

 Ipomoea. It is hkely to become leggy. Propagated 

 readily by seeds or cuttings. For cultural directions, 

 see 1 potncea. 



pentantha, G. Don (J. violacea, Choisy. Convolvulus 

 pentdnthus, Jacq.). St. perennial, somewhat shrubby 

 at base, twining 6-8 ft., pubescent or nearly glabrous: 

 lvs. cordate to ovate-lanceolate, acuminate: peduncles 

 slender, bearing 5-12 fls. in a loose cymose cluster; 

 corolla about 1}4 in. wide, short-funnelform, sharply 

 5-angled, rich violet-blue. June-Sept. Trop. Amer., 

 and as fiir north as Fla. B.M. 2151. B. 4:197. P.M. 

 6:219. In var. canescens, Hort. (J. can^scens, Benth.), 

 the whole plant is covered with short, brownish down. 

 B.R. 33:27. 



taninifolia, Griseb. Plant annual, usually low and 

 erect, at length twining if support is near, covered with 

 tawny yellow hairs: lvs. cordate-ovate, long-petioled: 

 peduncles bearing many fls. in dense involucrate clus- 

 ters; fls. less than J^in. long, violet. Cult, and waste 

 ground, S. C. to Ark., and southward.

JACQUINIA (Nicholas Joseph de Jacquin, 1727- 

 1817, collector and painter of West Indian plants). 

 Myrsindces^; by some separated, with Clavija and 

 Theophrasta, in Theophrastacese. Tropical American 

 trees and shrubs, seldom cultivated far South for orna- 

 ment. 



Leaves opposite or somewhat verticiUate, rigid, 

 margined, entire: fls. white, purple or orange, borne in 

 racemes, umbels or singly; corolla 5-fid, wheel- to sal- 

 ver-shaped, crowned at the throat and between the 

 lobes with 5 roundish appendages (staminodia) ; 

 stamens 5, inserted far dovm in corolla-tube, the fila- 

 ments subulate: berry leathery, few to several-seeded. 

 In the allied genus Theophrasta the corolla is cylindri- 

 cal, shortl}' 5-lobed, the appendages are fastened at the 

 b:ise of the corofla instead of the throat, and the berry 

 is many-seeded. — By the latest monographer (Mez, 

 Engler"s Pflanzenreich, hft. 15, 1903), 33 species are 

 described, of the warm parts of Amer. 



keyensis, Mez (J. armill/'iris, Ch.apm., not Jacq.). 

 Lvs. cuneate-spatulate or obovate, blunt, revolute at 

 the margin, usually whorled, 4 in. long, \^2 in. wide: 

 berry H'm. thick. S. Fla. and Bahamas. It is a low 

 tree (about 15 ft.), with evergreen lvs. somewhat like 

 box but obovate, and racemes of small white honey- 

 scented fls., which appear in winter. It appears to be
