ovary superior, oblong, glabrous, with 2 locules.<br />

Fruit a linear capsule, coriaceous, with valves<br />

perpendicular to <strong>the</strong> septum; seeds numerous, flat,<br />

with 2 hyaline-membranaceous wings. A genus<br />

<strong>of</strong> 2 species <strong>of</strong> tropical eastern <strong>and</strong> sou<strong>the</strong>rn<br />

Africa.<br />

1. Tecomaria capensis (Thunb.) Spach, Hist. Nat.<br />

BASIONYM: Bignonia capensis Thunb.<br />

SYNONYM: Tecoma capensis (Thunb.) Lindl.<br />

Clambering or semi-erect shrub, 3-4 m in<br />

length. Stems cylindrical, lenticellate, puberulous;<br />

cross section <strong>of</strong> <strong>the</strong> mature stem with peripheral<br />

phloem not forming a cross. Leaves opposite,<br />

imparipinnate, 7-11-foliolate, without tendrils;<br />

leaflets 1.5-4.2 × 1-3 cm, elliptical to subrounded,<br />

membranaceous, sessile, puberulent, <strong>the</strong> apex<br />

rounded, <strong>the</strong> base rounded or abruptly cuneate,<br />

<strong>the</strong> margins serrate; upper surface dull, pale, with<br />

12. TYNANTHUS<br />

slightly prominent venation; lower surface light<br />

green, dull, punctate, with slightly prominent<br />

venation, forming a conspicuous network, with<br />

tufts <strong>of</strong> hairs in <strong>the</strong> axils; petioles 1.5-2.5 cm long;<br />

pseudostipules absent. Flowers numerous, in<br />

axillary racemes; pedicel 6-10 mm long. Calyx<br />

green, crateriform, 5-7 mm long, 5-dentate,<br />

ciliate, puberulent; corolla orange or reddish<br />

orange, tubular, curved, 3.5-5 cm long, with 5<br />

oblong, unequal lobes, <strong>the</strong> 2 upper lobes smaller<br />

than <strong>the</strong> 3 lower; stamens 4, <strong>of</strong> equal length,<br />

exserted; ovary superior, oblong, glabrous, with<br />

a crateriform disc at <strong>the</strong> base. Capsule linear, 5-<br />

11 cm long <strong>and</strong> 7-8 mm wide; seeds in 2 rows,<br />

slender, 2-winged, <strong>the</strong> wings hyalinemembranaceous.<br />

Phenology: Collected in flower in February<br />

<strong>and</strong> March.<br />

Status: Exotic, cultivated, uncommon.<br />

Distribution: Cultivated in gardens along <strong>the</strong><br />

Cordillera Central, also on St. Croix <strong>and</strong> St.<br />

Thomas. Native to South Africa, but widely<br />

cultivated throughout <strong>the</strong> tropics.<br />

Small trees or lianas with tendrils. Stems cylindrical or occasionally quadrangular, interpetiolar<br />

zone not gl<strong>and</strong>ular; pseudostipules absent or foliaceous but early deciduous; cross section <strong>of</strong> <strong>the</strong> mature<br />

stem with a cross <strong>of</strong> 4 arms formed by <strong>the</strong> phloem tissue. Leaves opposite, 2- or 3-foliolate, <strong>the</strong> terminal<br />

leaflet usually replaced by a terminal, simple or trifid tendril. Flowers numerous, in terminal or axillary<br />

panicles. Calyx simple, crateriform, subtruncate, usually 5-denticulate; corolla white, zygomorphic,<br />

infundibuliform, bilabiate, divided up to half its length, pubescent outside; stamens 4, didynamous,<br />

subexserted; ovary superior, bicarpellate, conical, densely pubescent, <strong>the</strong> ovules in 2-4-series per locule.<br />

Fruit a linear capsule, compressed, smooth, with <strong>the</strong> valves parallel to <strong>the</strong> septum; seeds numerous,<br />

flat, with 2 hyaline-membranaceous wings. A genus <strong>of</strong> 14 species <strong>of</strong> tropical America distributed from<br />

sou<strong>the</strong>rn Mexico to Brazil <strong>and</strong> Bolivia.<br />

SYNONYMS: Bignonia caryophyllea Bello<br />

Tynanthus caryophylleus (Bello) Alain<br />

Bejuco de clavo<br />

Liana that climbs by tendrils, 10-20 m in<br />

length. Stems more or less quadrangular,<br />

tomentose, interpetiolar zone not gl<strong>and</strong>ular,<br />

usually with an interpetiolar line, attaining 3 cm<br />

or more in diameter; cross section <strong>of</strong> <strong>the</strong> mature<br />

stem with a cross <strong>of</strong> 4 arms formed by <strong>the</strong> phloem<br />

tissue, with a strong odor <strong>of</strong> cloves; pseudostipules<br />

foliaceous, ca. 1 cm long, deciduous. Leaves<br />

opposite, 2-foliolate, sometimes with a simple<br />

tendril, in <strong>the</strong> form <strong>of</strong> a spiral, up to 15 cm long;<br />
