ASCLEPIADE/E XXXI. PERGULARIA, 
oblong, acuminated, rounded at the base: having the margins 
and veins downy; cymes pedunculate, twin ; calycine segments 
obtuse, shorter than the tube of the corolla. h.%.S. Native 
of Java, Sumatra, Madura, &c., by the sea side. It differs 
from P. odoratissima in the leaves never being cordate. 
Approaching Pergularia. Fl. year. Shrub tw. 
3 P. minor (Andr. bot. rep. 184.) leaves cordate, obtuse; 
with an acumen, downy while young; umbels shorter than the 
leaves; calycine segments about equal in length to the tube of 
the corolla, h.%.S. Native of the East Indies. Curt. bot. 
mag. 755.? Tratt. tab. 713. P. odoratíssima, var. Smith, 
icon. pict. 3. p. 16. This is probably only a small variety of 
the first species, the leaves are rounder, with a more slender 
recurved acumen ; and the corollas orange-coloured or yellow, 
but also very fragrant; and the segments of the corolla are 
blunter and shorter. Leaves 13 inch broad, and the same in 
length.

4 P. rAnviFLORA (Blum. bijdr. p. 1056.) leaves subcordate- 
ovate, acute, downy on the margins and veins beneath ; umbel- 
lules pedunculate; calycine segments obtuse, shorter than the 
tube ofthe corolla. h. ^. S. Native of Java, about Kuri- 
pan, in calcareous soil. 
Small-flowered Pergularia. Fl. May, July. Shrub tw. 
5 P. vinrósA (Blum. bijdr. p. 1057.) leaves subcordate-oval, 
acute, very soft beneath ; umbellules simple; segments of calyx 
acute, shorter than the tube of the corolla. 5.^^. S. Native 
of Java, on mount Parang, in the province of Tjanjor. 
Villous Pergularia. Fl. July. Shrub tw. 
6 P. PA'LLiDA; branches downy; leaves oblong-cordate, 
acuminated, smooth ; umbels simple or compound, on short 
peduncles, many-flowered; corona length of tube, but the 
calycine segments are shorter; segments of corolla narrow, 
with revolute edges; tube glabrous inside. ^.^.S. Native 
of the East Indies, at Gongachora and Munghir; and Penang. 
Asclépias pállida, Roxb. fl. ind. 2. p. 48. P. limbàta, Wall. 
ascl p. 61. P. viridis, Ham. herb. Young shoots beset with 
small recurved hairs. Leaves 4 inches long, and 1-2 broad. 
Petioles, pedicels, and peduncles villous. The flowers are pale 
yellow, and not fragrant, or in a very slight degree. The length 
and narrowness of the segments of the corolla, and want of 
fragrance, seem to be the most obvious marks by which this 
can be distinguished from P. odoratissima. 
Pale-yellow-flowered Pergularia. Shrub tw. 
7 P. sancurnote’nta (Lindl. in hort. trans. 6. p. 72. Sims, 
bot. mag. 2532.) leaves ovate-lanceolate, quite glabrous; cymes 
many-flowered, shorter than the leaves; segments of corolla 
acuminated, obtuse. h.%.S. Native of Sierra Leone. Plant 
trailing, full of blood-coloured juice. Corollas greenish yellow.

8 P.PunPU'REA (Vahl. symb. 3. p. 44. Willd. spec. 1. p. 
1248.) leaves cordate, acuminated, glabrous ; umbels proliferous, 
shorter than the leaves; corolla with a villous throat, and 
narrow segments. 5. ^. S. Native of the East Indies and 
China.  Asclépias cordàta, Burm. ind. p. 72. t. 27. f. 2. 
Branches rather villous. Pedicels and calyx downy. Flowers 
purple ?

9 P.* Jaróxica (Thunb. jap. 111. Willd. 1. c.) leaves cor- 
date, glabrous ; umbels simple; calycine segments shorter than 
the tube of the corolla; segments of corolla obtuse, spreadingly 
reflexed. h. ^. S. Native of Japan. Stems glabrous. 
Leaflets of corona 5, subsagittate, erect, compressed, each 
furnished with a tooth outside. Stigma ending in a long thread. 
Perhaps a distinct genus, from the stigma terminating in a thread.

ovate, acuminated, glabrous; pedicels capillary, aggregate ; 
root large, succulent, size of a human head. h. 3t. C. 8. Native 
of the Cape of Good Hope, in Karro. Plant glabrous, with 
alternate branches. Leaves green above and pale beneath. 
Corolla an inch long. The root is eaten by the Hottentots. 
Perhaps a species of Ceropégia.

Cult. The greater number of the species of this genus are 
much valued for the fragrance of their flowers, and are well 
adapted to training up rafters or trellis work, in stoves or con- 
servatories. They grow well in a mixture of loam, peat, and 
sand; and cuttings strike root readily in heat, under a hand- 
glass. 
XXXII. DISCHI DIA (from ccc, dis, twice, and exo, 
schizo, to cut; in reference to the bifid leaflets of the corona).
