cavity of the testa, surrounded by a delicate membrane. Cotyledons 

 plain, white, very oily ; radicle small, conical ; plumule 2-lobed, 

 lobes notched. The seeds are eaten by the natives of Sikkim, who 

 call the fruit Kat'hior pot. An original specimen is in Sir William 

 Hooker's herbarium, from Buchanan Hamilton, labelled as from 

 Penang, with the MS. name of " Trichosanthes Theba." Roxburgh's 

 trivial name of heteroclita has been retained, for though it was in- 

 tended by its illustrious author to imply that the plant varies from 

 its congeners of the genus Trichosanthes, it will apply sufficiently 

 well in future for a plant which is heteroclite in respect of the 

 natural family {Cucurbitaceee) , to which it undoubtedly belongs. 

 Blume's descriptions are quite insufficient to determine whether it 

 belongs to his M. viacrocarpa or hexasperma, or either. These 

 plants are no doubt congeners of Hodgsonia, and considering that 

 the H. heteroclita ranges from the level of the sea at Penang, lat. 6° 

 north to alt. 6000 feet in Sikkim, lat 27° north, the probabilities are 

 great that it is also found in Java. The leaves vary from 2-lobed 

 to 5-lobed, usually the latter, and the lobes are much acuminate, 

 rarely blunt, coarsely serrated towards the tips or quite entire. 



The genus is named in honour of B. H. Hodgson, Esq., F.L.S., 

 Resident at Dajiling, where the plant was discovered, and whose 

 scientific services in the Himalaya justly merit the honour of bo 

 splendid a plant.
