VI. COLLECTED DESCRIPTIONS OF CUSCUTA. 
[It has been thought best not to reproduce the accounts of this genus contributed by

dition, 1878 ; and Gray’s Synoptical Flora of North America, II. part 1, — as they add little to his 
earlier papers. But descriptions of new species contained in them are included in the following

even on Euphorbia coroUata. It approaches C. hispidula so much that not improbably further investigation of, living 
plants may prove both to be only varieties of a single species, for which the name of C. porphyrostigma would be most 
appropriate, as all the forms that would belong to it are distinguished from eveiy other known North An 101 4o a r| S p ec ies
