N. Australia. Iskuds of the Gulf of Carpentaria, H. Brown. The specks is also in 

 Ceylon and the Lidian Peninsula, and has probably a much wider range m tropical Asia. 

 R. Brown indicated the close resemblance of the Australian to the Indian plant; and alter a 

 weful analysis of the flowers of both, I can detect no character to separate them unless tlie 

 Males of the corolla may be slightly more decurrent in the former thanm the latter. 



2. G. Muelleri, Bentn. A more or less pubescent t\viner, woody at 

 tl>e base. Leaves lanceolate, acutely acuminate, rounded or narrowed at the 

 base, narrow and 2 to G in. long on luxuriant branches, ovate-lanceolate and 

 1 to 2 in. on shorter less twining branches. Umbels dense, on very short 

 peduncles, soHtar\^ and interpetiolar or rarely axillary and opposite. Lalyx- 

 •egments ovate, obtuse, about 1 line long. Corolla-tube rather shorter _than 

 tbe calyx, bearded inside with reflexed hairs, the throat with very few prominent 

 feute scales alternating with the lobes and decurrent halfway down ; lobes 

 OTBte, obtuse, shorter than the tube. No corona. Stigma short, obtuse.
