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.

neous corona inclosed in the tube, 5-leaved ; leaves adnate to 
the tube of the filaments, lanceolate, connivent.  Anthers ter- 
minated by a membrane; pollen masses pendulous, fixed by

tives of South America, in shady places. Leaves opposite, pe- 
tiolate, cordate. Umbels pedunculate, interpetiolar. Corollas 
rather fleshy, usually bearded inside. 
1 S. muttirLora (Mart. l. e. p. 56. t. 33.) leaves cordate- 
obovate, acute; umbels many-flowered; tube of corolla gla- 
brous inside, shorter than the segments, which are linear.

LVI. LACHNO'STOMA (from Aaxyn, lachne, wool; and 
cropa, stoma, a mouth; throat of corolla bearded.) H. B. et 
Kunth, nov. gen. amer. 3. p. 198. t. 232. 
Lin. syst. Pentdndria, 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.—4A twining shrub; with oppo- 
site leaves ; and interpetiolar racemes. Flowers twin, approxi- 
mating in an umbellate manner. This genus is allied to 
Cynánchum on one hand, and Oxypétalum 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. marinom (H. B. et Kunth, l- c.) h.%.S. Native of 
New Granada, near Santa Fe de Bogota. Stems densely clothed 
with rusty hairs, as well as the peticles 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. MACROSCEPIS (from paxpoc, macros, long; and 
exer, 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. — Pentándria, Monogynia. Calyx 5-parted, ex- 
ceeding the corolla a little, bracteate at the base. Corolla 
thickish, 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 involuerated by bracteas. This genus is very nearly 
alied to Lachnóstoma, 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 Gonólobus.
