JACQUINIA 



1715 



plant, 



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

 pedicels, the bracts linear-lanceolate and dark green; 

 calyx J^in. 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. 563. J.H. III. 

 45:543. G. 27:678. G.M. 45:849. Gn.W. 21:51. An 

 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 Lib- 

 onia, Sericographis.) 



pauciflora, Benth. & 

 Hook. (Sericdgraphis pauci- 

 flora, Nees. Libonia flori- 

 bunda, C. Koch). A com- 

 mon conservatory 

 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 2006 ' Jacobuuapenrhosiensis. 



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. (Cyrtanthera 

 Ghiesbreghtidna, 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 

 as those of 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 mispelled 

 Ghiesbrechtiana. A good winter bloomer. 



penrhosiensis (Libonia penrhosiensis, Carr.). Fig. 

 2006. Much like J. pauciflora, but Ivs. 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 ofj. pauciflora and J. 

 Ghiesbreghtiana. Another and very similar hybrid of the 

 same parentage is Sericobdnia ignea, Lindl. & Andre. 

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

 little earlier 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, Schlecht. Justicia 

 atramentaria, Benth. Justicia Mohintli, Moc. & Sesse. 

 Sericographis Mohintli, Nees. Jacobinia Mohintli, 

 Benth. & Hook. Drejera Willdenowiana, Nees). Under- 

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

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

 corolla-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, Andre. Herb, velvety pubescent: sts. 

 prostrate, with erect flowering branches: Ivs. opposite, 

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

 fld. peduncled cymes, the bracts spatulate-oboyate and 

 obtuse; calyx-tube short and nearly hemispheric; 

 corolla bright scarlet, the slightly curved tube about 



1J4 in. long, pubescent outside; upper lip slightly 

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

 Uruguay. B.M. 8350. R.H. 1900:210. Handsome 

 warmhouse plant, suitable for baskets. 



J. Lindenii, Nichols. (Justicia Lindenii, Houll.), is a Mexican 

 subshrub, with long-ovate opposite decussate Ivs., and a dense 

 fascicled head of orange-yellow fls.: divisions of calyx 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). Convolvulacese. Sub- 

 tropical and tropical mostly climbing herbs, grown for 

 the convolvulus-like bloom. 



Allied to Ipomcea and Convolvulus, to which they 

 are probably inferior for garden cult. They are dis- 

 tinguished from Ipomcea by having 2 stigmas instead 

 of 1; and from Convolvulus 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; corolla more or less 

 campanulate, the plicate limb 5-angled or obscurely 

 5-lobed. Species 6Q-70 in Trop. Amer. and as far 

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



Jacquemontia pentantha makes an attractive green- 

 house climber for summer and autumn flowering, but is 

 not so desirable for this purpose as several species of 

 Ipomosa. It is likely to become leggy. Propagated 

 readily by seeds or cuttings. For cultural directions, 

 see Ipomcea. 



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

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

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

 Ivs. cordate to ovate-lanceolate, acuminate: peduncles 

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

 corolla about 1J4 in. wide, short-funnelform, sharply 

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

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

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

 the whole plant is covered with short, brownish down. 

 B.R. 33:27. 



tamnifolia, Griseb. Plant annual, usually low and 

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

 tawny yellow hairs: Ivs. 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). 

 Myrsinacese; 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 verticillate, 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 down in corolla-tube, the fila- 

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

 In the allied genus Theophrasta the corolla is cylindri- 

 cal, shortly 5-lobed, the appendages are fastened at the 

 base of the corolla 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. armilldris, Chapm., not Jacq.). 

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

 the margin, usually whorled, 4 in. long, 1J^ in. wide: 

 berry J^in. thick. S. Fla. and Bahamas. It is a low 

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

 box but obovate, and racemes of small white honey- 

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