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. \j . *"\ 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. MI.SOR (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. ^ . *"\ S. Native of the East Indies. Curt. bot. 

 mag. 755. ? Tratt. tab. 713. P. odoratissima, 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 1 } inch broad, and the same in 

 length. 



Smaller Pergularia. Fl. May, Aug. Clt. 1790. Shrub tw. 



4 P. PARVIFLORA ^ Blum, bijdr. p. 1056.) leaves subcordate- 

 ovate, acute, downy on the margins and veins beneath ; unibel- 

 lules pedunculate ; calycine segments obtuse, shorter than the 

 tube of the corolla. Jj . ^. S. Native of Java, about Kuri- 

 pan, in calcareous soil. 



Small-Jioirered Pergularia. Fl. May, July. Shrub tw. 



5 P. VILLOSA (Blum, bijdr. p. 1057.) leaves subcordate-oval, 

 acute, very soft beneath ; umbellules simple ; segments of calyx 

 acute, shorter than the tube of the corolla. 1? . . S. Native 

 of Java, on mount Parang, in the province of Tjanjor. 



Ullous Pergularia. Fl. July. Shrub tw. 



6 P. PA'LLIDA ; branches downy ; leaves oblong-cordate, 

 acuminated, smooth ; umbels simple cr 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. Jj . *"\ S. Native 

 of the East Indies, at Gongachora and Munghir; and Penang. 

 Asclepias pallida, Roxb. fl. ind. 2. p. 48. P. limbata, 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 no: 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. 



Pafe-yellow-flowered Pergularia. Shrub tw. 



7 P. SASGUISOLE NTA (Lindl. in hort. trans. 6. p. 72. Sims, 

 bot. mag. 2532.) leaves ovate-lanceolate, quite glabrous ; cymes

 1 24S.) leaves cordate, acuminated, glabrous ; umbels proliferous, 

 shorter than the leaves ; corolla with a villous throat, and 

 narrow segments. Ij . ^\ S. Native of the East Indies and 

 China. Asclepias cordata, Burm. ind. p. 72. t. 27. f. 2. 

 Branches rather villous. Pedicels and calyx downy. Flowers 

 purple ? 



Purph -flowered Pergularia. Shrub tw. 



9 P. ? JAPOXICA (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. ^ . ^\ 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.

10 P.? EDU'LIS (Thunb. prod. p. 38. fl. cap. 2. p. 151. act. 



nov. petrop. t. 14.) stem herbaceous, filiform, twining; leaves 

 ovate, acuminated, glabrous ; pedicels capillary, aggregate ; 

 root large, succulent, sire of a human head. 17 . Tf.. ^. S. 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 Ceropegia. 



Edible-rooted Pergularia. PL tw. 



N. B. What is Pergularia lucida and P. angustifblia, Fisch. 

 hort. gorenki ? 



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.
