Cult. The species answer well for training up the rafters, in 

 a stove, or warm part of a greenhouse. A mixture of loam, 

 sand, and peat, or any light rich soil, suits them well ; and cut- 

 tings strike root freely in sand, under a hand-glass, in heat.

 fessor at Erlang). Mart. nov. gen. bras. 1. p. 55.

 tube gibbous at the base ; limb 5-parted, spreading. Stami- 

 neous corona inclosed in the tube, 5-leaved ; leaves adnate to

1 S. MULTIFLORA (Mart. 1. c. p. 56. t. 33.) leaves cordate- 

 obovate, acute ; umbels many-flowered ; tube of corolla gla- 

 brous inside, shorter than the segments, which are linear.

 rocks, in the province of Pernambuco. Cynanchum multiflo- 

 rum, Spreng. syst. add. p. ] 10. Corollas white.

 vate, acute; umbels few-flowered ; tube of corolla bearded in- 

 side, equal to the segments of the limb. T; . ^. S. Native of 

 Brazil. Corollas white. ?

3 S. LONGIFL6RA (Mart. 1. c.) leaves cordate, obovate, acute, 

 villous ; umbels many-flowered ; tube of corolla very hairy 

 inside, 3 times longer than the segments, which are lanceolate.

LVI. LACHNO'STOMA (from Xa x ^, lachne, wool ; and 

 tTTo^ia, stoma, a mouth ; throat of corolla bearded.) H. B. et 

 Kunth, nov. gen. amer. 3. p. 198. t. 232. 



LIN. SYST. Pentandria, Digynia. Calyx 5-parted. Corolla 

 somewhat salver-shaped, with a short tube, a 5-parted spread- 

 ing limb ; and a bearded throat ; segments of the limb ovate- 

 oblong, acute, rather unequal-sided. Stamineous corona in- 

 serted in the throat of the corolla, 5-leaved ; leaflets lunately 

 2-lobed, fleshy. Anthers terminated by a membrane ; pollen 

 masses compressed, laterally fixed by their tapering tops, pen- 

 dulous. Stigma mutic, peltate. A twining shrub ; with oppo- 

 site leaves ; and interpetiolar racemes. Flowers twin, approxi- 

 mating in an umbellate manner. This genus is allied to 

 Cynanchum on one hand, and Oxypetalum on the other ; but 

 is distinguished from them, in the form of the corolla, and cor- 

 puscles, as well as by the mutic stigma, and in the corona 

 being inserted in the throat of the corolla ; and from both, in 

 the filaments being adnate to the tube of the corolla, and in the 

 throat being bearded. 



1 L. TIGR!NUM (H. B. et Kunth, 1. c.) fj . ^. S. Native of 

 New Granada, near Santa Fe de Bogota. Stems densely clothed 

 with rusty hairs, as well as the petioles and peduncles and ca- 

 lyxes. Leaves elliptic-oblong, acuminated, rounded at the base, 

 villous on both surfaces, and beset with rusty hairs on the nerves 

 and veins beneath. Petioles 4-5 inches long, and 2 broad. Ca- 

 lyx hairy. Corolla hairy outside ; segments elegantly and reti- 

 culately spotted.

LVII. MACROSCE'PIS (from ^ Kpoe , macros, long ; and 

 oxtTi-w, skepo, to cover; in reference to the calyx being larger than 

 the corolla.) H. B. et Kunth, nov. gen. amer. 3. p. 200. t. 233. 



LIN. SYST. Pentandria, Monogynia. Calyx 5-parted, ex- 

 ceeding the corolla a little, bracteate at the base. Corolla 

 thickisli, with a globose-ventricose tube, and a spreading, 5- 

 parted limb ; segments of limb obliquely ovate, obtuse. Corona 

 of 5 fleshy scales, inserted in the throat of the corolla. Gynos- 

 tegium saucer-shaped, hardly exceeding the tube of the corolla. 

 Filaments connate, adnate to the tube of the corolla. Anthers 

 terminated by a membrane ; pollen masses compressed, pendu- 

 lous, fixed by their tops. Stigma mutic, peltate. Follicles un- 

 known A twining plant, with hairy branches. Leaves oppo- 

 site, obovate, cordate, hairy. Peduncles interpetiolar, 2-flowered ; 

 pedicels involucrated by bracteas. This genus is very nearly 

 allied to Lachnostoma, from which it is distinguished by the 

 large calyx, by the structure of the corona, gynostegium, and 

 beardless throat. There is also considerable affinity between 

 this genus and Gonolobus.
