from H. carnosa, but a comparison with the other species, 

 will scarcely support its correctness. In H. trinervis, the 

 flower is much paler, and the leaves of H. pallida are 

 when in health, fully as dark, as those of some of the other 

 species. Perhaps any of the three specific names which it 

 had previously obtained, are less objectionable than pallida. 



IV. HOYA POTTSII. 



This species is a valuable addition to our gardens, for, 

 besides having peculiar beauties, it is of easy culture and it 

 blossoms freely. The late Mr. John Potts, on his return 

 from China in August 1822, and shortly before his death, 

 gave Mr. Sabine a single leaf of this Hoya, which he had 

 gathered in one of his excursions near Macao ; it was care- 

 fully planted, and anxiously attended to, until it sent forth 

 a shoot from its base in the spring of 1824. In the autumn 

 of the same year the plant put forth blossom-buds ; these 

 dropped off, but perfect flowers were produced in the fol- 

 lowing year. 



In record of the original discovery of the plant by Mr. 

 Potts, and as a proof of the esteem in which he was held by 

 his employers, the species was named in the Garden of the 

 Horticultural Society in compliment to him. 



The stem is slender, greenish-brown, covered irregularly 

 with warts, from which small roots are freely produced. The 

 leaves are cordate, sharply acuminate, having occasionally a 

 rusty stain partly spread over them, beneath of a pale whitish 

 green without veins, above light yellowish green, with three
