The flowers of this well marked species are often produced endogenously 
like those of C. glomerata and, while they are usually formed into dense, 
compact clusters about the host, the inflorescence does not have the rope-like 
appearance of the former. The flowers of this are usually of a much darker

This little dodder is commonly mistaken for C. Gronovii, an error that 
should not occur, however, if one compares the capsules which are pointed 
with C. Gronovii and depressed with this species. It is frequently found
