A Study of the Scale-characters of the Northeastern American 
Species of Cuscuta. 
By W. D. MaTrHEew. 
(PLates CLXIV.-CLXV.) 
In the schemes for the classification of Cuscuta, the scale- 
characters are given but small prominence, though it would seem 
that as a convenient means of distinguishing the species one from 
another they may be of considerable service. They vary a great 
deal in the different species, but are apparently quite constant in 
each and seem to belong to two or three distinct types. The 
classification here made is intended rather as a key than as any 
attempt at a systematic division. as 
The scales may be separated from the first into two types, one Di 
of which is deeply crenulate, the other fringed with processes: os 
To the first class belong the two introduced species, C. epi 4
