Notes upon the aisove List. 



Juncus a/pinus, Villars, with castaneous capsules, is the character- 

 istic plant of the (iulf of St. Lawrence and extends locally southward 

 to the St. John valley in Maine and to Willoughhy Lake, Vermont. 

 /. a/pinus, var. insignis. Fries, the commoner plant of the St. John 

 and Kennebec valleys and occurring locally on Lake Champlain, has 

 pale capsules and is usually a larger plant. Both forms occur in 

 northern Europe. 



/uncus articulatus, L. The typical form has brown tiowers, the 

 castaneous capsules 3-4 mm. long, gradually tapering to the mucro- 

 nate tip. Var. obtusatus, Engelm., with greenish or greenish brown 

 fiowers, the pale capsules 2.5-3 mm. long and abruptly mucronate, 

 often replaces it in brackish or alkaline situations, and on the coast 

 is occasionally found in salt-marshes. 



Juncus brevicaudatus. /. canadensis, var. brevicaudatus, 

 Engelm., Trans. St. Louis Acad. ii. (1866) 436; var. coarctatus, 

 Engelm. 1. c. ii. (1868) 474. This northern plant has long seemed 

 to the writer to be unfortunately treated as a form of the essentially 

 southern and, in New England, mostly coastal /. canadensis. A 

 detailed examination of the great mass of material now accumulated 

 by the Gray Herbarium and the New England Botanical Club indi- 

 cates several important points of distinction and confirms the long 

 established conviction, which has been shared by others who know 

 the two plants in the field. 



Juncus cafiadensis is a stout plant with the inflorescence (when 

 well developed) ovoid or broader in outline, at most one-third longer 

 than broad, the branches spreading or subascending ; the glomerules
