bracts small. The latter in both genera are in two series, pro- 
vided we count as a second series the 2 or 3 quite short outer 
bracts at the base of the anthodia of Hartwrightta. The genus 
therefore should be inserted after A//omia, in Durand’s Index, 
under number 2441 b. This disposition is concurred in by the 
late Dr. Sereno Watson, whose kindly counsel in this and other 
matters is gratefully acknowledged.

The Winter Buds of Utricularia. 
By JoHn M. HOLzincEr. 
(Plate CLXI.) 
In the summer of 1891 Dr. J. H. Sandberg, collecting in 
Northern Minnesota, sent to the United States Department of 
Agriculture a Utricularia (No. 516) which seems to be Utricularia 
intermedia, Hayne, though the details of leaves do not agree 
with Reichenbach’s figures of this species. The specimens all — a 
have the good hibernacula or winter buds, to which reference 
is made in Gray’s Synoptical Flora, Vol. ii., Part I, p. 315, a8 
“hybernacular tuber-like buds.” In these specimens they are ee 
about 6 mm. in diameter, and of the shape of a small bird’s at Sere 
They consist of numerous broadly palmate scales (Fig. c), crowded a 
along the short axis, and standing out at right angles from it. os 
These scales are beset along the margin with tufts of bristles; 
which, falling on the outside of the bud, give it the appearance of a 
a small hairy cocoon. Its structure thus hardly warrants the us¢ 
of the term “ tuber-like.” pe eee
