or Concord, Massachusetts (RHopora, xviii. 249-50, 1916). S. 
roseum is abundant everywhere on sea-ledges of the outer islands in 
eastern Maine, and occasional on the mainland and islands as far 
west as Monhegan. (Ruopora, xv. 140, 1913). It also grows on Mt. 
Horrid, Rochester, Vermont. S. stoloniferum occurs only at Cumber- 
land, Maine (E. B. Chamberlain). S. telephioides reported by Mrs. 
N. F. Flynn from Colchester, Vermont. (Vt. Ag. Exp. Station, Bull. no 
187, 209, 1915) where it is a roadside escape, does not quite match 
other material of that species and may be a variant of S. triphyllum. 
Tillaea Vaillantit Willd., reported from Nantucket by Mrs. M. P. 
Robinson, Floyd, Bicknell and others, seems to be only a form of T. 
aquatica with long pedicels, not the T. Vaillanti of Europe according 
to Dr. Harold St. John.

Tue TARDY FLOWERING OF PLANTS IN EASTERN MASSACHUSETTS IN 
THE SPRING OF 1917.— In Ruopora, xii. 127-129 (1910), a list of 
plants which had been observed in flower in eastern Massachusetts 
prior to the end of April, 1910, was published. That season was a 
phenomenally advanced one and the list as published, although after- 
wards demonstrated to be incomplete, enumerated 119 species. The 
current spring, of 1917, has been so phenomenally backward as to 
excite comment even of the least observing people and at a conference 
of members of the New England Botanical Club held at the Club Her- 
barium on May 11th a canvas was made of the observations to date 
of the members present. The very meagre list which it was possible 
to prepare of plants which had been observed in flower to date, May 
11th, is in such striking contrast to that of April, 1910, that it is 
thought that other members of the Club and readers of RHODORA 
will be interested to have it accessible. The following list, then, 
enumerates all the species of wild plants which are definitely known to 
have flowered in 1917 in eastern Massachusetts prior to May 12th.
