38 xcv. ASCLEPIADEJ;. (J. D. Hooker.) [Pergularia. 



Follicles lanceolate, terete, rather turgid. Seeds ovate, concave. DISTRIB. 

 Species about 10 ; Asiatic and African. 



The excessively sweet-scented P. odoratissima, Smith (Icones Pictse, t. 15), is stated 

 to be Indian, but the plant so called by Roxburgh, Wight, &c., is P. minor. Smith's 

 figure exactly resembles P. pallida, which is nearly scentless. 



* Pollen-masses elongate-clavate or subcylindric. 



1. P. pallida, Wight $ Arn. Contrib. 42 ; leaves ovate-cordate acuminate, 

 flowers scarcely fragrant, corolla yellowish white, lobes linear much larger than 

 the tube which is glabrous within, coronal scales with broad points not spurred 

 behind. Wall. Cat. 8181 ; Wight Ic. t. 585 ; Brand. For. Fl. 334 ; Kurz For. 

 Fl. ii. 203 ; Dene, in DC. Prodr. viii. 619. P. coromandeliana and P. montana, 

 Dene. 1. c. Asclepias pallida, Roxb. Hart. Seng. 20, and FL Ind. ii. 48. 



TROPICAL HIMALAYA; from Murree ascending to 5000 ft. eastward to SIKKIM and 

 southward on the plains to BOMBAY and CENTRAL INDIA, BEHAR and BIRMA. 



Except by the absence of the sweet scent and pale flowers I do not know how 

 this can be distinguished from Smith's figure and description of P. odoratissima. 

 Follicles in Eoxburgh's figure 6 in. long and 1 broad (l as drawn partially open), 

 lanceolate. Seeds % in. long, broadly ovate. 



** Pollen-masses globosely obovoid or obscurely broadly obconic. 



2. P. minor, Andr. Sot. Rep. t. 184 ; leaves orbicular or ovate cordately 

 2-lobed acuminate, flowers very fragrant yellow or green, corolla-lobes oblong 

 about equalling the tube or shorter, tube pubescent above within, coronal 

 scales double inner with a long subulate point. Sot. Mag. t. 755. P. odora- 

 tissima, Wight Contrib. 43, and Ic. t. 414. Kurz For. FL ii. 203. Asclepias 

 odoratissima, Roxb. Hort. Seng. 20 ; and Fl. Ind. ii. 46 ; Watt. Cat. 8182 ; 

 Orah. Cat. Bomb. PL 120. 



Cultivated or native throughout India, and the Eastern Islands, China and Japan ; 

 native of the Himalaya (Brandts). Tsegai hills in AVA, Griffith. 



Though confounded with P. odoratissima, this appears to be perfectly distinct in 

 the smaller flowers and short broad corolla-lobes. Follicles lanceolate, 3 in. long 

 by in. diam. ; pericarp thick, glabrous. Seeds ~ in. long, broadly ovate. The 

 coronal scales vary excessively in length acuteness and in the comparative length 

 of the outer and inner divisions. 



3. P. puberula, Miguel Fl. Ind. Sat. ii. 495 ; leaves ovate or oblong- 

 ovate acuminate, base rounded -or cordate, sepals broadly ovate, corolla pubes- 

 cent without and within, lobes linear longer than the tube, coronal scales 

 laterally compressed 2- winged dorsally below produced into an inflexed subu- 

 late point exceeding the anthers. 



PENAKG, Phillips. DISTRIB. Java. 



Habit of P. pallida, from which the short sepals, pubescent corolla, and laterally 

 much-flattened scales which project far outwards from the column, and the form of 

 the pollen-masses, at once distinguish it. 



34.STEPHANOTXS, Thouars. 



Twining glabrous shrubs. Leaves opposite, coriaceous. Cymes umbelliform, 

 axillary ; flowers large, white. Calyx 5-partite, segments large. Corolla 

 coriaceous, tubular or salver-shaped, tube cylindric, base swollen ; lobes twisted, 

 overlapping to the right. Coronal scales in the Indian species (in others 

 adnate to the anthers, erect, dorsally flattened). Column very short; anthers 

 with an inflexed tip; pollen-masses one in each cell, erect, waxy, shortly
