LINACEAE 
LINUM USITATISSIMUM L. 
Casual and transient. It grew sparingly in an old field in 
1899, but I have seen it since on Nantucket only in waste ground 
at Surfside, July 9, 1912, the most forward buds showing blue tips. 
It is included in Mrs. Owen’s catalogue, and Mr. Floyd's notes 
report it as having been collected by Miss Nina K. Goddard, in 
1895, and by Mrs. Mary A. Albertson. 
LINUM VIRGINIANUM L. 
Not uncommon on the eastern side of the island from ise 
to Tom Never’s Pond, especially at outlying points about Saul’s 
Hills, growing in dry sandy soil. Elsewhere it was met with only 
at a single station in Trot’s Hills. The young plants ot be 
detected early in June and in some seasons are but a few inches 
high late in the month. The fruit is mature by the end of August, 
although flowering may continue until after the middle of Sep- 
tember.
