Hance. (T. Sampson, June, 1865.) 
This pretty and delicate little plant, which (in the dried state, at 
least) much resembles Brymaria cordatuy Willd., and still more the 
Ceylon Stellaria drymarioides, Thw., does not seem allied to any of the 
species enumerated in Drs, Hooker and Thomson's Conspectus of the 
Indian Seda (Journ, of Linn, Soc. ii. 93 sqq.) ; but, as none of tliem 
are found in Khasia, the flora of which most nearly approaches that of 
China, this is not surprising. The extreme delicacy and tenuity of the 
parts renders the examination of the flowers a task of some difficulty.

This plant was first gatliered in June, 1864, by Mr. Sampson, in a 
palm-grove in the extreme west of the province of Kwangtung, near 
the borders of Kwangsi. He found it very sparingly, and of the two 
specimens he gave me I retained one for my own herbarium, and sent 
the other to Kew, with the Natural Order only noted. I afterwards 
learnt from Mr. Bentham that Professor Oliver thought it w^as proba- 
bly a new species of Ophloxylon. Mr. Sampson, during the past sum-
