28 Descriptions of Plants belonging to the Genus Hoy a. 



Linn;eus's Supplementum Plantarum, a native of Ceylon, and 

 is figured and described in the Hortus Malabaricus, Vol. ix. 

 plate 15, page 25, under the name of Watta-Kaka-Codi. If a 

 judgment may be formed from this figure, the plant is par- 

 ticularly handsome. The Stapelia Cochinchinensis of Lou- 

 reiro, which has been called Hoya Cochinchinensis, certainly 

 belongs to another genus, as I have already observed. The 

 Asclepias viminalis of Swartz, a native of Jamaica, and con- 

 sidered as a Hoya by Baron Jacquin, under the name of 

 Schollia viminalis, probably belongs to some other genus, no 

 true Hoya having yet been found in any part of the New 

 World. In the Flora Nepalensis of Mr. David Don, page 

 130, two Hoy as, natives of Nepal, are given on the authority 

 of original specimens, received from and named by Dr. 

 Wallich. The first is called H. lanceolata, the second H. 

 linearis, they both have very small foliage, and w r ould be 

 valuable additions to our gardens. 



The specimens which I have had the opportunity of ex- 

 amining, afford evidence of the existence of three hitherto un- 

 described species. The first is a native of the more northern 

 part of New South Wales, with leaves varying from elliptic 

 to obovate ; this is in the Herbarium of Mr. Robert Brown, 

 and is named by him Hoya Australis, it having been referred 

 by him in his Prodromus Florae Novae Hollandiae, Vol. i. 

 page 460, w ith a doubt, to H. carnosa. The second is also in 

 the same collection, and comes from the Nicobar islands ; it 

 has beautiful globose umbels of flowers, which are very nu- 

 merous in each umbel, and ovate-lanceolate leaves ; Mr. 

 Brown has named this Hoya Nicobarica. The last has very 

 narrow lanceolate leaves, an imperfect specimen of which
