102 Rhodora [May 



bridge and other towns in the southern part of Worcester County, 

 Massachusetts, where I have observed it every month in the year 

 and in three or four different years, I have found it always sterile in 

 that vicinity. I have seen no record or explanation of this peculiar- 

 ity anywhere, and it would be interesting to know how far this has 

 been the experience of other collectors. The absence of fructifi- 

 cation seems to cause a greater vegetative growth. In the fall of 

 1897 I collected in Southbridge a specimen which was fully twelve 

 feet long; and this fact was made use of by Lloyd and Underwood 

 in their review of the genus in North America (Bull. Torr. Club, 27 : 

 159. April, 1900) in giving the dimensions of L. clavatum. 



One prominent feature of these sterile specimens is that they 

 totally lack the characteristic articulated appearance mentioned by 

 Mr. Leavitt in his recent paper, a fact for which I can suggest no 

 explanation at present.

UTRICULARIA MINOR IN VlNNICUNNET, MASSACHUSETTS. In an 



interesting article in Rhodora, vol. 4, p. 42, from the pen of Alice 

 G. Clark I find the inquiry whether anyone else has collected Utri- 

 cularia minor recently, and if so under what conditions. 



Utricularia minor, L. was found in July, 1894, by Mr. Oakes Ames 

 near the shore of Lake Vinnicunnet. The following year I collected 

 at the same locality not only this species but also U vulgaris, L., 

 U. inflata, Walt., U. purpurea, Walt., and U. cornuta, Michx., and 

 entered them at the exhibition of wild flowers held by the Massachu- 

 setts Horticultural Society early in July at Horticultural Hall in 

 Boston. Almost yearly since then the place has been visited and U. 

 minor was growing there still in July, 1901, although not abundantly. 

 It grows in shallow water in a somewhat boggy, muddy soil mixed 

 with sand. Some years the water of the lake has been very high, 

 but this has not seemed to have any hurtful influence upon the 

 plants. Last year I found another station not ar from the first one 

 where a little hillock of decayed pond-weeds, particularly of the 

 Giant Bulrush, Scirpus lacustris, L., was carpeted with this small 

 threadlike decumbent Utricularia. Among the species of Utricularia, 

 U. minor is the earliest flowering. I have found it in bloom in
