perfectly evident that he had no definite idea as to the limits of his 

 species, and this statement is fully corroborated by the writings of 

 both Carrington and Spruce. On this account it seems best to give 

 up the name reclusa altogether and to apply to this distinct species 

 the later name serrifiora of Lindberg, a course already pursued by 

 Jack and others. C. Virginiana is scarcely distinct from C, serriflora 

 and apparently represents a luxuriant form of the species. The 

 range of C. serriflora extends from Canada to the Gulf States, 

 the species becoming more abundant southward. In New England 

 it seems to be rare but has probably been overlooked. From other 

 species growing on rotten logs it may be distinguished by its widely 

 spreading and deeply bifid leaves, the acute divisions being straight 

 or slightly connivent; by its leaf-cells with uniformly thickened 

 walls ; by its dentate or denticulate perichaetial bracts, and by its 

 thin-walled, three-angled perianth with ciliate mouth. It varies in 

 color from green to brown, and does not become bleached out with 

 age. The true C. catenulata is not yet definitely known from North 

 America.

JUNCUS ARISTULATUS IN NEW ENGLAND. 



Eugene P. Bicknell. 



It appears from Mr. Fernald's carefully prepared list of New Eng- 

 land Juncaceae published in Rhodora 6: 34-41, that Juncus aristu- 

 lattis Michx. is not know^n as a New England plant. In regard to 

 this Mr. Fernald writes me, " I searched in vain for it in such herba- 

 ria as were accessible when I was preparing my list, for it belongs to 

 the flora which is so characteristic of Nantucket and Martha's Vine- 

 yard, and I was surprised not to find it creeping into our borders." 

 It should be recorded therefore that this rush does occur within these 

 borders and, moreover, not at all as a feeble straggler but as a defi- 

 nite feature in the flora, reaching a very full development and fruit- 

 ing prolifically. On September 18, 1899, I found it on Nantucket 

 where it was not uncommon about one general locality somewhat east 

 and north of the middle of the island. Specimens there collected 

 have been forwarded to the Gray Herbarium. It may be added that
