Raymond Athey to E.T. Browne: Since this species seems to be the same as #647 except for the number of perigynia I wonder if #665 and #656 could not be C. Grayii and #640 is C. grayii var hispidula - #640 and #665 were growing together. I used B&B to determine all numbers. I just do not have the experience to resolve what I am asking you to do.
