of species in the genus Cuscuta, and there is no doubt that ase 
are very difficult of discrimination from dried specimens. With 
regard to the three under review, I do not profess to have examined 
critically the numerous specimens at Kew and in the British 
Museum bearing these names. It is indeed qiiahie that some 
of them are incorrectly named; but anyone interested in com- 
ogres the figures in Plate 493 ‘will at once see that these three 
re easily distinguished from each other. To what extent the 
flo wers vary in the same - serge — only be ascertained by the 
examination of a large number of fresh specimens, and I hope to 
have an opportunity of doing thie f in some species during the pre-
