214 ON THE ASCLEPIADE.E.

Linnean Herbarium : it therefore rests entirely upon Her- mann's specimens, which, though collected 140 years ago, were by maceration in water so far recovered, as to enable me with certainty to determine its genus. The fourth is Periploca sylvestris, Willd. sp.pl. I, p. 1252.

34] LEPTADENIA.

Char. Corolla subrotata, tubo brevi, fauce coronata, squamis 5 sinubus impositis : limbo barbatoy sestivatione valvata.

Corona staminea nulla.

Anther <s libera?, apice simplices.

Massce pollinis erectse, basi affixae, apice coarctato pellu- cido !

Stigma muticum.

Folliculi

Habitus, llerbce ? perennes ? volubiles, tomento impal- pabili, pulvereo, cinerascentes. Folia plana, opposita. Vmbellce interpetiolares, quandoque cymosae. Corpuscula stigmatis minuta.

Patria. India Orientalis, Africa aequinoctialis et septen- trionalis.

Obs. Of this genus I have examined three species in the Banksian Herbarium, none of which are as yet described, though one of them was collected by Forskael ; it is un- named, however, and does not correspond with any of his descriptions.

SARCOLOBUS.

Char. Corolla subrotata, 5fida. Fauce nuda. Corona staminea nulla. Anther m membrana terminates . 353 Massce pollinis erectae, basi affixae. Stigma muticum. Folliculi ventricosi, carnosi. Semina marginata 1
