 in late June and July. The common plant of New England. 



SciRPus CYi'ERixf.s (L.) Kuuth has been discussed by me in detail' 

 and a number of allied species and varieties set off from it. The true 

 S. cjipcriiius with the s))ikelets all glomerdate has reddish brown 

 involucels, scales and bristles, and occurs from Xew England to \'ir- 

 ginia, Tennessee, and Arkansas, being commonest in the middle 

 Atlantic States. The common representative of S. cypcrinus in New- 

 foundland, eastern Canada and northern New England, differs so 

 generally in the color of its involucels and bristles that it is here desig- 

 nated 



S. CYPERixus, var. pelius, n. var. Involucels dull brown or drab, 

 with blackish bases: rays elongate the glomerules mostly distinct: 

 bristles drab or smoke-color. — The common extreme northward, 

 occurring generally from Newfoundland to Ontario, south to i\m- 

 necticut, central New York, and Michigan. The following, from 

 among nearly 100 sheets examined, are characteristic specimens.

Ryncho.spera .macrostachya Torr., var. inundata (Oakes), n. 

 comb. "Corymbs almost wholly terminal. Clusters loose, few 

 flowered. This variety a[)pears at first sight like a distinct species. 

 Grows in deeper water than the common one, which is the cause of 

 its different ap})earance. ^^'est ponil, Plymouth, Mass. Mr. Tucker- 

 man, 1839. The common form is very abundant, at the same locality."
