4,18 ASCLEPIATDE^. 



5-partite, inserted into the column below the anthers: leaflets foliaceous, not deciirrent. 

 Pollinaria ovoid, hanging with a curved tail from the base of the gland. Stigma depressed, 

 ■with 2 blunt points. Follicles smooth, linear : seeds comose. — Suffrntescent branched clim- 

 bers, often nearly aphyllous ; leaves opposite ; mahels fete-floioered, sessile or sutsessile ; co- 

 rolla-segments glabrous. 



7. A. filiforiue, Gr. {n. sp.). Glabrous, diffuse-twiuing ; leaves linear, tapering into 

 the petiole, pointed ; pedicels short, about 2-4 times as long as the minute flower ; sepals 

 oval ; coroUa-segments oblong-linear, blunt ; Crown-leaflets oval, blunt, equalling the an- 

 thers, longer than the short column-stalk. — Mttastelma linearifolium, Bieh. (Cub. t. 57), is 

 perhaps an aUied species, but has (in the figure) pointed crown -leaflets and a much longer 

 column-stalk. Several feet high, at length aphyllous ; branches cylindrical, thin, but grow- 

 ing woody : internodes about 2", leaves H"(-|"), 3-5-nate pedicels 2'" long ; calyx scarcely 

 exceeding the short coroUa-tube ; corolla-segments |"' long, horizontally expanded; follicles 

 linear-acuminate, minutely truncate at the summit, \\", seeds li'" long, the latter half as 

 long as the silky -white terminal coma. — Hab. Jamaica!, .4/., M'Na6, March, Wullschl., 

 common; [Cuba!]. 



8. A. leptocladon, Gr. Branches elongated, glabrous ; leaves oblong or linear-ob- 

 long, mucronate, petioled ; pedicels puberulons, exceeding the petiole, 3-4 times as long as 

 the minute flower ; sepals oval-roundish ; corolla-segments ovate-oblong, bluntish ; crown- 

 segments bluntly deltoid-roundish, equalling the anthers, longer than the short column- 

 stalk. — Vincetoxicum, Bees, Cynanchum fnnale, Poir.? — Stem twining, with filiform 

 trailing branches : internodes often 2" long ; leaves 4"'-6"' long, 1 J"'-2"' broad ; pedicels 

 2"'-3"', corolla 1"' long.— Hab. Jamaica!, March; [Haiti]. 



3. SEUTEEA, Beichenb. 



Calyx 5-leaved. Corolla rotate, 5-partite, dextrorsely contorted. Crotim 5-leaved, folia- 

 ceous, inserted into the suhsessile column below the anthers. Pollinaria ovoid, tailed, hang- 

 ing from the base of the gland. Stigma conical, entire. Follicles smooth, lanceolate-acu- 

 minate ; seeds comose. — A twining, filiform, glabrous herb j leaves opposite, linear, acumi- 

 nate, subsessile : ^ms distant; nrabfis peduncled. 



9. S. maritima, Eeichenb. — Lyonia, Ml. — Leaves 2"-l", peduncles l"-i", pedicels 

 l"'-2"', corolla-segments 2'", puberulous follicles 2" long ; sepals minute, lanceolate, ciliate ; 

 corolla-segments ovate-lanceolate, twice as long as the column ; crown-leaflets oblong, retuse, 

 or blunt, a little exceeding the anthers.— Hab. Bahamas I, Swains. ; [South Carolina, among 

 Halophytes ; Florida I, Texas !]. 



4. ENSLENIA, Nutt. 



Ca^a 5-partite. Corolla rotate, B-partite, slightly contorted : crown 5-leaved, inserted 

 into the subsessile column below the anthers : leaflets tbliaceous, hastate. Pollinaria ovoid, 

 pendulous : tail horizontal, inserted into the gland above its base. Stigma depressed, with 

 2 minute points. Follicles " oblong-lanceolate, smooth ; seeds comose." — ^Twining, glabres- 

 cent herbs ; leaves opposite, cordate with an open sinus, long petioled ; flowers corymbose : 

 corymbs peduncleu. 



10. E. jamaiceusis, Gr.{n.sp.). Leaves mucronatehluntish ; crown-leaflets broadly 

 hastate : terminal lobe ligulate, entire, shortly emarginate. — Habit and most characters of 

 E. albida, Nutt., but leaves rounded towards the pointleted or mucronate summit, and crown 

 awnless : Cynanchum racemosum, Jacq. (Amer. Pict. t. 80, or Roulinia Jacquini, Decs.), 

 from its figure is another nearly allied congener. Leaves 3"-4" long, 2"-2i" broad ; pe- 

 duncles as long as the petioles ; sepals oblong, 1'" long ; coroUa-segments oblong-linear, ex- 

 panded, 3'" long, twice as long as the column ; roundish-quadrate base of the crown-leaflets 

 as long as the linear, incurved, terminal lobe. — Hab. Jamaica!, Wils, 



5. ASCLEPIAS, L.
