within, or these obsolete: lobes relatively broad and short. Corolla-tube usually gradually 
dilated into the funnelform throat. Carpels and follicles as in Urechites. 
Corolla yellow, less than 3 em. long ; limb 1 as long as the throat : calyx-lobes acuminate. 
l. R. Sagraei. 
Corolla white, over 4 em. long; limb about as long as the throat: calyx-lobes acute. 2. R. biflora. 
1. Rhabdadenia Ságraei (A. DC.) Muell. Arg. Similar to R. biflora in habit, but

longer than the leaves : calyx-lobes subulate above an ovate base : corolla yellow, the throat 
1-1.5 em. long ; lobes about 3 as long as the throat: follicles slender, 8-12 cm. long: 
seed with the beak plumose to the base. . [ Echites Sagraei A. DC.] 
In sandy thickets, Pine Key. Florida. Also in the West Indies. 
2. Rhabdadenia biflóra (Jacq.) Muell. Arg. Stems greatly elongated, often very 
woody, branched, twining or floating : leaf-blades leathery, oblong, or oblong-lanceolate, 
4-9 em. long, apiculate, glabrous, short-petioled : cymes 1—3-flowered : calyx-lobes oblong 
or nearly so, 5-6 mm. long, merely acute : corolla white, the throat campanulate ; lobes 
about as long as the throat: follicles slender, 12-15 cm. long. [Echites paludosa A. DC.] 
On muddy shores, southern peninsular Florida and the Keys. Alsoin the West Indies. 
10. ECHITES P. Br. 
Twining vines, with somewhat woody stems. Leaves opposite: blades flat, entire. 
Flowers in terminal or axillary cymes. Calyx-lobes 5. Corolla relatively large, salver- 
form, the tube cylindrie, but abruptly somewhat swollen. Stamens included : anthers 
appendaged at the base. Carpels2. Ovules numerous. Follicles 2, spreading at maturity. 
1. Echites umbellàta Jacq. Stems widely twining: leaf-blades leathery, ovate to 
oval, 4-9 cm. long, short-pointed, truncate or cordate at the base, more or less involutely 
folded and recurved : cymes several-flowered : calyx-lobes triangular, 2.5-3.5 mm. long: 
corolla white or greenish white ; tube 5-6 cm. long, swollen about the middle ; lobes 1.5- 
2.5 em. long, rounded: follicles 15-20 em. long. 
In sandy soil, southern peninsular Florida and the Keys. Also in the West Indies. 
11. TRACHELOSPERMUM Lemaire. 
Vines, with woody stems or sometimes nearly erect shrubs. Leaves opposite : blades 
entire. Flowers relatively small, in compound cymes. Sepals narrow, glandular within. 
Corolla funnelform or salverform : tube slightly dilated above: lobes 5. Stamens mainly 
included: anthers sagittate, converging about the stigma. Disk 5-lobed. Carpels 2, 
united by the somewhat thickened styles. Stigmas ovoid or globular. Ovules numerous. 
Follicles 2 together, much elongated. Seeds many, each tipped with a long coma. 
l. Trachelospermum diffórme ( Walt.) A. Gray. Stems 3-5 m. long, twining, more 
or less pubescent when young : leaf-blades ovate or oval to elliptic or lanceolate, rather 
thin, 3.5-9 cm. long, acuminate, sometimes abruptly so, paler beneath than above, short- 
petioled ; cymes several-flowered : calyx-lobes lanceolate-subulate, 3-3.5 cm. long : corolla 
greenish ; tube 5-6 mm. long with a prominently swollen throat ; lobes ovate, shorter than 
the tube : follicles slender, 15-22 cm. long. 
In low grounds and on river banks, Delaware to Florida, Texas and Mexico, most!y near the coast. 
Spring and summer.
