necticut, for it has been found on Fisher's Island, New York, only 

 four or five miles from the Connecticut shore. Dr. J. K. Small 

 informs me that the citation of this plant from Connecticut in 

 Britton's Manual, p. 592, has reference to specimens from the 

 Fisher's Island station. 



Euphorbia Ipccaciianhae, L. In the John A. Lowell Herbarium 

 at the Boston Society of Natural History there is an undated speci- 

 men of this plant collected at Enfield, Connecticut, by Dr. M. M. 

 Reed. A letter discovered by Mr. C. H. Bissell and kindly com- 

 municated by him to me has shown that Dr. Reed was a friend of 

 Dr. J. W. Robbins of Uxbridge, Massachusetts. An undated speci- 

 men of this plant, collected in Enfield, by Robbins, is in the 

 herbarium of Mr. J. N. Bishop at Plainville, Connecticut, but no 

 specimen of it has as yet come to light in the herbarium of Robbins, 

 part of which is at Mt. Holyoke College and part at South Natick, 

 Massachusetts. It is probable that the specimens gatliered by Dr. 

 Reed and Dr. Robbins date from between 1824 and 1830. 



Euphorbia platyphylla, L., collected on a dump at Cambridge, 

 Massachusetts, by Mr. Walter Deane on October 10, 1885, has not 

 reappeared and can hardly be included in the list above. 



Euphorbia Preslii, Guss. The report of this species by Professor 

 Jesup in his list of plants near Dartmouth College, New Hampshire, 

 was probably based on the plant which is now known as E. hirsuta, 

 Wiegand. Professor Lyman of Dartmouth College writes me that 

 the only specimen of true Euphorbia Preslii in Professor Jesup's 

 herbarium comes from Massachusetts. 



Two western species of Euphorbia which are not sufficiently per- 

 manent to be included in the list above should be put on record 

 here. Euphorbia prostrata, Ait., gathered on cotton-waste at 

 Maiden, Massachusetts, Sept. 20, 1890, by Mr. F. S. Collins, is now 

 in the herbarium of the New England Botanical Club. A small 

 scrap of E. serpens, II BK. is in the herbarium of Brown Uni- 

 versity. It was gathered at Gilmanton, New Hampshire, August, 

 187 I, by Rev. Joseph Blake. 



Mercurialis annua, L. has been gathered on wharves in Bangor, 

 Maine, in 1903, by Mr. O. W. Knight, and at East Somerville, 

 Massachusetts, in the same year, by Mr. A. H. Moore and the writer. 

 It has been known in New England, however, for a much longer 

 time, since of two sheets of it in the herbarium of the Boston
