July, 1863 (J. L. Russell); oak woods and rocky banks, North Salem, 
July 10, 1901 (J. H. Sears). 
Me iLotus INDICA (L.) All. should be watched for in waste lands. 
It is represented in the Club Herbarium or the Gray Herbarium by the 
following New England specimens, all from eastern Massachusetts: 
dump, Dracut, August 6, 1884 (C. W. Swan); Charlestown, July 4, 
1879 and July 23, 1881 (C. E. Perkins); Charles River dumping 
grounds near Mt. Auburn, Cambridge, 22 August, 1897 (B. L. 
Robinson). 
DEsMODIUM CANESCENS (L.) DC. is so rare in Middlesex County 
as to be practically unknown to local botanists. It was collected by 
the late William Boott at at least two stations, as shown by his labels: 
“W. Cambridge, roadside opposite W. Niles’s house," August 15, 
1853, and August 24, 1854; and "roadside, Winchester, opposite 
.Everett's," August 22, 1869. Are these stations still in existence? 
LINUM FLORIDANUM (Planch.) Trel. is a plant which has but re- 
cently been known in New England. It was collected August 7, 
1902, by Mrs. Clara Imogene Cheney in a bog at Centerville on Cape 
Cod and a beautiful sheet of Mrs. Cheney's material is preserved in 
the Club Herbarium. 
MYRIOPHYLLUM ALTERNIFLORUM DC. Twenty years ago this 
boreal species was unknown from the continent of North America, 
but in 1891 Morong! recorded it from Lake Temiscouata (coll. 
Northrop) and Lake Memphremagog (coll. Churchill) in Quebec. 
Gradually our knowledge of its American distribution has increased 
until we now know it to be common from eastern Newfoundland to 
western Maine and to occur, perhaps locally, south to Massachusetts 
and west to Lake Superior? The Massachusetts specimens, as repre- 
senting the southern limit of the species, as far as known, are worthy 
special record; and it is also worthy of note that some of them were 
collected but unrecognized many years before the plant was recorded as 
a native of North America. The Massachusetts specimens thus far 
known are: Mystic Pond, August 26, 1853, and August 6, 1865 (Wm. 
Boott); Westford, September 2, 1902 (Miss E. F. F letcher); Sprague's 
Pond, Readville (C. E. Faxon). The material from Sprague’s Pond 
was mixed with M. ambiguum, forma capillaceum, a comparatively 
! Morong, Bull. Torr. Bot. Cl. xviii. 242 (1891). 
? Collected on Isle Royale, Michigan, August 6, 1909, by W. S. Cooper.
