1010 LXXX. ASCLEPIADEjE. [Marsdenia. 



9. TfL. longiloba (corolla-lobes oblong), Benth. Fl. Atustr. iv. 340. A 

 glabrous twiner. Leaves petiolate, ovate-ianceolate or lanceolate, acuminate, 

 rounded or trimcata at the base, 1 J to 2^in. long. Umbels simple and solitary, 

 on peduncles rarely exceeding the petioles. Pedicels 3 to 4 lines long. Calyx- 

 segments ovate-lanceolate, rather obtuse, about 1 line long, glandular. Corolla 

 with a very broad and short tube, glabrous inside, the limb spreading to 4 or 5 

 lines diameter, the lobes twice as long as the tube, rather narrow, obtuse or 

 almost acute, with 5 prominent scales in the throat alternating with the lobes. 

 Corona-segments each with 2 very prominent vertical auricles on the adnate base, 

 the free part erect, narrow, short or nearly as long as the anthers. Pollen- 

 masses narrow-oblong. Stigma narrow-conical, about as long as the anther- 

 membranes. 



Hab.: Towards the Tweed River. 



10. M. leptophylla (leaves slender), F. v. M. in Herb. Rook.; Benth. Fl. 

 Austr. iv. 340. A slender, slightly pubescent twiner. Leaves narrow-linear, 

 contracted into a short petiole, 1 to 2in. long. Umbels simple and solitary, 

 rather dense, on short interpetiolar peduncles. Pedicels short. Calyx-segments 

 oblong, rather obtuse, nearly 1 line long. Corolla-tube nearly ij line long, 

 contracted upwards, the upper part pubescent inside, with raised lines decorrent 

 from the sinus of the lobes to about halfway ; lobes much shorter than the tube, 

 broad, obtuse. Corona-segments small, peltate, shortly aurieulate at the base, 

 the free erect part very short. Pollen-masses short but erect. Stigma narrow- 

 conical, almost rostrate.

11. 1V[. Iieichhardtiana (after L. Leiehhardt), F.v.M. Fragm. v. 160; 

 Benth. FL Austr. iv. 341. Stems woody at the base, with long twining branches, 

 the young parts glaucous or white-tomentose. Leaves linear, obtuse, contracted 

 into a very short petiole, rather thick, 1^ to 3 or even 4in. long. Flowers large 

 for the genus, in simple and solitary dense umbels, on short interpetiolar 

 peduncles. Pedicels short. Calyx-segments ovate, obtuse, about 2 lines long. 

 Corolla-tube 2 lines long, contracted at the throat with a thickened ring prominent 

 inside, but less so than in M. viridifiora and quite glabrous ; lobes rather shorter 

 than the tube, obtuse. Corona-segments small, the adnate part broad and 

 slightly aurieulate at the base, the free erect part very short. Stigma conical, 

 obtuse, shorter than the anthers. Pollen-masses oblong. Follicles thick, ovoid 

 or ovoid-oblong, scarcely acuminate, 1^ to Sin. long. — Leichhardtia australu, R. 

 Br. in App. Sturt. Voy. 18. 



Hab.: Narran Eiver, the pods eaten by the natives under the name of " Doubah", Mitchell. 



12. M. viridifiora (flowers green), R. Br. Prod. 461 ; Benth. Fl. Austr. iv. 

 341. A twiner, quite glabrous or with a rusty pubescence on the young shoots 

 and inflorescence. Leaves either long-lanceolate with a broad sometimes almost 

 hastate base with rounded auricles, or all linear-lanceolate, rarely almost ovate, 

 acute or rarely obtuse, 2 to 4in. long. Flowers green, in simple umbels,, solitary 

 or rarely 2 together on short interpetiolar peduncles. Pedicels sleiider, 3 to 4 

 lines long. Calyx-lobes ovate, very obtuse, about 1 line long. Corolla-tube 

 broad, rather shorter than the calyx, half-closed at the throat by a prominent 

 ring and bearded inside, the hairs either in tufts opposite each sinus or forming 

 a complete ring; lobes ovate, obtuse, spreading to nearly 3 lines diameter. 

 Corona- segments aurieulate at the base, the free erect part obtuse, much shorter 

 than the anthers. Stigma very short, obtuse. Follicles about 3in. long, above 

 lin. broad, scarcely acuminate. — Dene, in DC. Prod. viii. 615. 



Hab.: Keppel Bay and Broadsound, B. Brown; Brigalow scrub, from the Dawson and 

 Burdekin to the Burnett Rivers, F. u. Mueller ; Rookhampton, Dallachy and othert ; Suttoi'
