SOLANACE^l. XXXV. NOLANA. XXXVI. TRIGUERA. XXXVII. CRABOWSKIA. XXXVIII. CESTRUM. 



stems procumbent ; leaves crowded, linear, with revolute mar- 

 gins ; calyx ventricose, ovate, with lanceolate segments. O- 

 H. Native of Peru, in sandy places. Stems white, angular. 

 Leaves sessile, twin, unequal in size, white beneath, obtuse. 

 Peduncles very short. Corolla bluish-violet, thrice as long as 

 the calyx. 



Revolule-\ea\ed Nolana. PI. procumbent. 



Cult. All the species of Nolana are showy when in blossom, 

 much like those of some trailing species of Convolvulus, and are, 

 therefore, well adapted for decorating flower borders. The 

 seeds should be sown on a gentle hot-bed in spring ; and the 

 plants, when of sufficient size, or about the middle of May, 

 should be finally transplanted to the open ground, where they 

 will flower and ripen seed ; or the seeds may be sown at once 

 in the open border, in a warm sheltered situation. 



XXXVI. TRIGUE'RA (so named by Cavanilles after D. 

 Triqueros, a Spanish botanist, first discoverer of the plant.) 

 Cav. diss. 2. t. A. Schreb. gen. no. 282. Juss. gen. p. 125. 

 ed. Usteri, p. 140. Lam. ill. t. 114. 



LIN. SYST. Penldndria, Monogynia. Calyx 5-cleft to the 

 middle ; segments unequal, acute, permanent. Corolla campa- 

 nulate, irregular ; throat dilated into a short, ventricose, sub- 

 bilabiate, plicate limb, which is longer than the calyx ; segments 

 unequal : 2 superior ones sub-reflexed. Stamens 5 ; filaments 

 very short, joined at the base by a 5-toothed, epipetalous 

 membrane, which surrounds the ovarium. Anthers sagittate, 

 conniving into a cone, dehiscing by 2 pores at the apex, ex 

 Juss. Stigma capitate. Drupe small, globose, half covered by 

 the calyx, furrowed, 4-celled ; cells 2-seeded. Seeds ovate, 

 compressed, usually only one in each cell coming to maturity. 

 Annual herbs, with extra-axillary, 2-flowered peduncles. 



1 T. AMBROSI'ACA (Cav. diss. 2. append. 2. t. A.) stem fur- 

 rowed, winged : superior leaves obovate, toothed, or serrated, 

 downy, decurrent. O- H. Native of Spain, in Andalusia, 

 in gravelly places about Cordova. Lam. ill. t. 114. T. bac- 

 cata, Gmel. syst. p. 338. Verbascum Osbeckii, Lin. spec. 255. 

 Buxb. cent. 5. t. 17. f. 52. Tourn. itin. 2. p. 83. icone, 

 Stem hardly branched. Radical leaves obovate, entire. Pedun- 

 cles twin, or bifurcate. Corolla like that of Hyocyamus, pur- 

 plish-violet ; segments of the limb roundish, crenated. Drupe 

 dry. Cotyledons of Datura, ex Poir. The plant has a strong 

 scent of musk. 



Ambrosiacal Triquera. PI. 1 foot. 



2 T. INODORA (Cav. diss. 2. append. 3.) leaves ovate-lanceo- 

 late, quite entire, glabrous, hardly decurreat. Q. H. Native 

 of Spain, along with the preceding. The whole plant is gla- 

 brous. The flowers are prettier than those of the preceding ; 

 the tube of the corolla is shorter ; the throat and rays pale 

 violet ; the limb cream-coloured ; the lobes neither acuminated 

 nor emarginate ; the urceolus is larger, and almost wholly hides 

 the ovarium. 



Scentless Triquera. PI. J to f foot. 



Cult, For culture and propagation see Nolana above. 



XXXVII. CRABO'WSKIA (named in honour of H. Cra- 

 bowski, M.D., one of the editors of Flora Selesiaca.) Schlecht, 

 in Linnaea, 7. p. 72. Lycium species, Lin. Ehretia species, 

 Lher. 



LIN. SYST. Pentdndria, Monogynia. Calyx sub-campanu- 

 late, regularly 5-toothed, valvular in aestivation. Corolla with 

 a short, funnel-shaped tube, and a 5-parted limb ; segments of 

 the limb spreading, or reflexed, 4 of which are convolute in 

 aestivation, the fifth external, with the margins covering the 

 edges of those near it. Genitals exserted. Stamens 5, equal ; 

 filaments free from a little above the base of the tube, densely 

 villous in the middle ; the villi decreasing toward the base. 



Style terete ; stigma sub-capitate, or bifid. Ovarium 4-celled ; 

 cells 1-ovulate. ? Drupe propped by the permanent calyx, glo- 

 bose, containing 2 2-celled, 2-seeded, woody putamens. Em- 

 bryo hamately curved, cylindrical. A shrub, with the habit of 

 the genuine species of Lycium, much branched, furnished with 

 axillary spines. Leaves scattered, quite entire. Flowers from 

 fascicles of leaves, or evolute branchlets, or sub-corymbose 

 from the tops of the branchlets, hence they appear as if they 

 were disposed in terminal panicles. 



1 C. BORHAAVIJJFOLIA (Schlecht, in Linnasa, 7. p. 72.) |j . 

 G. Native of the South of Brazil, in woods, where it has been 

 collected by Sello, but has been introduced from Peru into the 

 gardens of this country. Lycium borhaaviaefolium, Lin. suppl. 

 p. 150. Lam. diet. 3. p. 510. Ehretia halimifolia, Lher. stirp. 

 1. p. 45. t. 83. Duham. arbr. 1. p. 306. no. 5. Lycium heter- 

 ophyllum, Murr. comm. gcett. 1783. p. 6. t. 21. Leaves cori- 

 aceous, glaucescent, with a saltish, bitterish taste. Corolla 

 white, having the throat veined with green. Genitals white. 

 Stigma green. Nuts form of those of Coffea Arabica, convex 

 on one side, marked by a slender furrow in the middle, obtuse 

 at top, and perforated by 2 roundish holes at the base ; 

 hence it is tridentate, the first tooth from the middle of the 

 back, the other 2 from the sides, sometimes, but only by abor- 

 tion, 1-celled. Albumen copious, fleshy. 



Borhaavia-leaved Crabowskia. Fl. April, May. Clt. 1780. 

 Shrub 6 to 10 feet. 



Cult. This singular shrub is of the most easy culture and 

 propagation. A light rich earth suits it best ; and cuttings 

 strike root readily under a hand-glass. 



TRIBE VII. CESTRI'NE^E (this tribe contains plants agree- 

 ing with the genus Cestrum in the characters given below.) 

 Limb of corolla plicate, valvate, or induplicate in aestivation. 

 Calyx 5-toothed. Corolla funnel-shaped, 5-lobed, regular ; 

 tube elongated ; limb usually spreading. Stamens 5 ; anthers 

 dehiscing lengthwise. Ovarium seated on a cupulate disk. 

 Pericarp capsular or baccate. Placentas adnate to the disse- 

 piment. Embryo nearly straight, with a cylindrical radicle, 

 and roundish leafy cotyledons. 



1. Pericarp baccate.

 name of betony, but for what reason applied to this genus is 

 unknown to us.) Lin. gen. no. 261. Schreb. gen. no. 342.

 campanulate, 5-toothed, almost regular, valvate in aestivation. 

 Corolla with an elongated tube, widening gradually to the top ; 

 limb 5-parted, subplicate, spreading, or revolute, regular, condu- 

 plicate in aestivation. Genitals inclosed ; filaments naked, or fur- 

 nished with a small tooth, or villi, or down near the base, or 

 where the parts are adnate to the corolla. Anthers nearly glo- 

 bose, dehiscing lengthwise. Ovarium 2-celled, few-ovulate. 

 Stigma subcapitate, concave, or somewhat 2-lobed. Berry 

 girded by the permanent calyx, 2-celled, or only 1-celled from 

 the dissepiment having vanished, ex Geertn. few-seeded ; pla- 

 centas double, free, central. Seeds 3-sided. Embryo straight- 

 ish, with a cylindrical radicle, and roundish foliaceous cotyle- 

 dons. Unarmed shrubs. Leaves and branches scattered, the 

 former quite entire, and usually furnished with spurious brae- 

 teas, or small leaves in their axils. Flowers racemose; racemes 

 bracteate, axillary, elongated, or short, disposed in corymbs, 

 spikes, or fascicles. Corollas never blue, nor red, usually 

 sweet-scented, having the sides of the segments generally to- 

 mentose. Berries black, or blackish blue. The leaves exhale 

 a fetid, nauseous smell when bruised.
