I.—On some species of Cuscuta. By Cuaries C. Basrneton, 
M.A., F.L.S., F.G.S. &e.* 
[ With a Plate. ] 
SINCE the paper upon Cuscuta (Ann. xiii. 246) was published, 
I have had an opportunity of examining recent specimens of C. 
approximata, and been favoured with a drawing of it (PI. I. fig. 1.), 
and also of the flowers of C. Epithymum and C. Trifolii from the 
accurate hand of my friend Mr. J. W. Salter. I learn from these 
beautiful drawings and an examination of numerous specimens, 
that some slight alteration is necessary in the specific characters 
and descriptions of the plants, all however tending to show their 
distinctness in a clearer manner; and I trust that the difficulty 
inseparable from the examination of such inconspicuous objects, 
after the specimens have been dried, will be considered as a suffi- 
cient excuse for the inaccuracies which I am now endeavouring 
to correct. 
In this paper I shall give revised specific characters for the 
three species above-mentioned, and append to each of them such 
observations as are requisite.
