Mr. F. S. Collins at Falmouth Heights, Mass. Since then, two other 

 collectors have obtained it in the vicinity of East Falmouth, in the 

 waters of Vineyard Sound, at a place called Menauhant; viz., Rev. 

 G. W. Perry of Auburn, Me., in the summer of 1881, and Mrs, H. L. 

 Chambre of Fall River, Mass., in 1882. 



These constitute the third and fourth recorded instances of its oc- 

 currence on the American coast. It was first found by Mr Charles 

 Congdon more than thirty years ago, cast ashore at Smithville near 

 Wilmington, N. C. This specimen was figured and described by 

 Harvey in the first volume of the '* Nereis." 



It had, however, been previously identified by Prof. J. W. Bailey, 

 who received it from Mr. Hooper of Brooklyn, along with fifty or 

 more other plants, I am fortunate enough to have the letter of Prof. 

 Bailey to Mr. Hooper in which he makes report of his study of this 

 lot of specimens. For sufficient reasons, he does not appear to have 

 satisfactorily determined many of them, so he writes: 



" You will see by the above how blind a guide I am in the path 

 you have entered. I try to console myself for my incapacity, by say- 

 ing that most of the specimens sent which I am in doubt about are 

 not in a perfect and fully-developed condition, and that others are 

 decidedly new, or, at any rate, not like anything in my herbarium. 



I have worked hard at these specimens, have dissected every one 

 of them, and compared them with everything which they at all re- 

 semble, and yet how few I have made out! However, I am paid for 

 my labors by making out that curious plant M. i. which beyond any 

 doubt is the Arthrocladia villosa of Duby, a very rare plant and new 

 to the American flora." As little confidence as Prof. Bailey felt in 

 his knowledge of algae, he was about the only American who, at that 

 time, knew anything at all about them.

Rosa minutifolia. — Through the kind exertions of Miss F. 

 Fish of Sauzal, mature fruit of this interesting species, described in 

 the August number of the Bulletin, has been obtained and is being 

 widely distributed, so that we may hope soon to see it in cultivation. 

 The fruit is globose, crowned with the persistent erect calyx-lobes, 

 deeply red-brown, bristly-hispid ; seeds generally few, bearing the 



woolly, at length deciduous style. 



In the description of the flower it ought to have been mentioned 

 that the outer calyx-lobes are pinnatifid, which however is alluded to 

 at the end of the article. The locality is Sauzal, not Sanyal as 



printed.

EpipactiS Helleborine, the orchis new to America, which wai 

 found near Syracuse in 1879, has been discovered growing in con- 

 siderable quantity (100 to 200 individuals) on a wooded slope of 

 Scajaquady's Creek, in the northerly part of this city. A specimen 

 has been sent to Dr. Gray, who, while pronouncing it to be identical 

 with the Syracuse plant, declares that he can discover no valid dis-
