82 Rhodora [April 



Plymouth is the one which should be credited with the plants referred 

 to in the old account. — John Robinson, Peabody Academy of 

 Sciences, Salem, Massachusetts. 



Hkmicarpha in Eastern Massachusetts. — The occurrence of 

 Hemkarpha subsquarrosa, Nees, in the town of Framingham, 

 Massachusetts, was reported by the Rev. Ernest C. Smith (Rhodora, 

 i. 98), — the first record of its discovery in Middlesex County. On 

 October 13th, 1 901, while examining with Mr. E. F, Williams the 

 peculiar Mora about Winter Pond in Winchester, eight miles northwest 

 of Boston, I discovered several minute plants of Hemicarpha growing 

 on a gravelly bank of the Pond at about high water mark. A week 

 later the plant was again found, this time by Mr. Williams, growing on 

 a sandy shore at another part of the same pond. These latter plants 

 were of a much larger size. This discovery of the plant is of 

 interest as adding another station in Middlesex County, — a station 

 which also appears to be the most northern yet recorded in Massa- 

 chusetts. — E. L. Rand, Boston, Massachusetts. 



A COTTON-GRASS new to North America. — While examining 

 some Cypcraceac in the Herbarium of Dr. Dana W. Eellows of Port- 

 land, Maine, I was surprised to see a strange Eriophon/m, superfi- 

 cially resembling E. virginiatm, but quite lacking the brown scales so 

 Characteristic of that plant. An examination of Dr. Fellows's speci- 

 men shows it to be Eriophonan polystachyon, var. Vaillantii, Duby in 

 DC. & Duby, Bot. Gal. pt. 1, 487. From the common B. polystachyon 

 with umbels of long-peduncled spikelets, var. Vaillantii, which is 

 apparently rare in Europe, is distinguished by the sessile or very 

 short-peduncled spikelets. From E. virginicinn, which it habitally 

 resembles, it is quickly separated by its lead-colored scales, silvery- 

 white straight bristles, narrowly cuneate-obovoid obtuse achenes, and 

 the very early fruiting season ; E. polystachyon and its variety fruiting 

 in June, while the rusty-scaled E. virginicum fruits in late summer 

 and autumn. Dr. Fellows's material was collected June 16, 1901, on 

 Peaks Island in Portland Harbor, where the dense-headed var. Vail- 

 lantii is as common as the true Eriop/iorum polystachyon.- — M. L. 

 Fernald.
