Wall. Cat. 8226. Cynoctonum ovalifolium and C. Blumei, Dene, in DC 1 . 

 Pi-odr. viii. 529, 528. Holosternma laeve, Blume Bijd. 1056. 



PENANG, Wallich ; MALACCA, Maingay. DISTRIB. Java. 



Leaves 3-4 by 1 in., coriaceous, pale beneath, nerves spreading; petiole -f in. 

 Sepals ovate. Corolla % in. diara. ; segments broadly ovate, quite glabrous. Column 

 sessile. Follicles 5 in. long, thickly coriaceous, terete, tapering to a narrow but 

 stout point, tip recurved. Seeds ^ in., very broad and flat. "Produces an excellent 

 caoutchouc" (Wallich). Making allowance for the variability of the corona in this 

 genus, I am disposed to unite with this the C. formosanum, Maxim. (Diagn. PI. Nov. 

 Asiat. 801), and Cuming's No. 774 from the Philippines. 



5. C. alatum, Wight fy Arn. Contrib. 56 ; twining, puberulous or 

 glabrate, leaves linear ovate or oblong acute base contracted cordate pale 

 beneath, umbels shortly peduncled pubescent, corona short cupular plaited 

 irregularly crenate, follicles narrowly 2- winged. Cynoctonum alatum, Dene, 

 in DC. Prodr. viii. 529 ; Wight Ic. t. 1280. 



NILGHERRY Mrs., Gardner, &c. TRAVANCORE, at Coimbatore, Wight. 



Stem slender, sometimes softly pubescent. Leaves lg-2^ in., rarely more, very 

 variable in breadth, glabrous or puberulous above ; basal lobes rounded, sinus open 

 or almost closed ; petiole ^-f in. Umbels 1 in. diam., peduncle and pedicels pubes- 

 cent. Calyx lobes ovate. Corolla \ in. diam., glabrous, segments oblong-ovate. 

 Follicles 2 2 in., dorsally compressed. Wight's figure represents the whole plant as 

 far too hairy ; he gives Coimbatore as the only habitat, but his specimens are marked 

 from the Nilgherries, as are all the others I have seen (Gardner, Hohenacker, 

 Schmidt, G-. Thomson). In the " Contributions " he gives Coromandel as the only 

 natiye country, which is unlikely. The plaited corona has obscure thickenings on 

 some of the folds of the inner face which are rudimentary inner processes. 



6. C. pauciflorum, Br. in Mem. Wern. Soc. i. 45 ; twining, nearly 

 glabrous, leaves ovate or ovate-lanceolate acuminate, base broadly cordate, lobes 

 rounded, umbels shortly peduncled and flowers glabrous, corona much longer 

 than the sessile column 5-lobed with 5 intermediate teeth, follicles terete.

DECCAN PENINSULA ; from the Concan southwards to Travancore. CEYLON, very 

 common in the Central Province. 



Stem slender. Leaves 2-2 \ by \-l\ in., broadest at the base, rather coriaceous ; 

 petiole -1 in., glabrous or puberulous ; stipular leaves rounded, | in. diam. or less. 

 Pedmicle shorter than the petiole. Flowers \ in. diam. Sepals lanceolate. Corona 

 nearly equalling the corolla, campanulate, plicate, large lobes sometimes 2-fid at tho 

 tip. Follicles 2^ in. long, thinly coriaceous, beak slender. Seeds orbicular, flat, | in. 

 diam. This at first sight resembles C. alatum, but the leaves broad at the base at 

 once distinguish it. The name pauciflorum is not very distinctive. 



7. C. Wallichii, Wight Contrib. 56 ; twining, glabrous, leaves ovate- or 

 oblong-lanceolate finely acuminate membranous base deeply cordate with 

 rounded decurved or incurved lobes, umbels shortly peduncled and flowers 

 glabrous, corona campanulate plicate shortly 5-6-lobed lobes toothed. Wall. 

 Cat. 8224. Cynoctonum. Wallichii, Dene, in DC. Prodr. viii. 528. f 



KHASIA and JYNTEA Mrs. ; at the foot of the hills, Wallich, &c. 



Stems slender. Leaves 3-5 by 1-2 in., pale beneath, nerves very oblique, basal 

 sinus rounded, open or almost closed by the incurved lobes; petiole 1-1 in. 

 Peduncles much shorier than the petioles, pedicels slender. Sepals ovate. Corolla
