We can perceive no difference between Roxburgh’s plant and that from China. We have asserted it to 
be a climber on Roxburgh’s authority, as our specimens are not of sufficient length to enable us to 
determine that point ourselves. It is remarkable that it should not have been observed by Loureiro, par- 
ticularly as from Roxburgh’s description it appears to be a very large plant “ climbing over trees,” &c. 
We have also received, from Mr. Millett, Wrightia tinctoria, Br.

We have named this species in honour of our friend Dr. Wight, who has studied the Indian genera of this 
difficult Natural Order with peculiar zeal, and from whom we have derived much assistance in ascertain- 
ing the Chinese species. The genus was instituted for the Asclepias longistigma of Roxburgh, (FI. Ind. t. 
•2. p. 46,) which differs from the Chinese plant by having the leaves much broader, and the lacinula of the 
coronal leaflets shorter than the leaflets. Our description is entirely derived from specimens received direct 
from China from Mr. Vachell and Mr. Millett; the only individual in the Collection being destitute of flowers, 
and having but two or three leaves, may perhaps be something different.

We possess specimens from Dr. Wight from the peninsula of India, agreeing so well with the Chinese 
plant, that we consider them the same. In the Chinese individual the leaves are slightly narrower 
and less pubescent beneath, but even in Indian specimens that character is exceedingly variable. We 
have only two other Aselepiadece from Canton, but they are not among Captain Beechey’s Collection : 
the one is Asclepias Curassavica, L., the other is what Dr. Bindley has described (Hort. Soc. Trans, v.
