rowly lanceolate, sharply serrate leaves, tomentose and hoary be- 
neath, and with the scale-tips ‘‘ twice as long as those of any other 
species I have seen.” Again, there is nothing to distinguish it 
from V. novebdoracensis. It is also worthy of note that Elliott 
was not at all certain of the identity of his plant with that de- 
scribed by Walter. After seventy years Britton reduced it to a 
variety, but, strangely enough, his description in the Illustrated 
Flora and in the Manual refers mainly to V. glauca. After de- 
scribing V. noveboracensis with leaves 5-12" wide he says for the 
variety: ‘* Leaves * * * broader; * * * some scales sometimes 
merely acute,” both characters directly at variance with Elliott’s 
description, and agreeing scarcely better with Walter’s. More re- 
cently E.S. Steele * has discussed the matter, and regards the name 
V. tomentosa Ell. as belonging to a hydrophile form of the south At- 
lantic coast, with linear-lanceolate leaves, sparsely and finely serrate 
and gray-tomentose beneath. In his opinion it is a distinct species. 
My own examination of the two sheets in the National Herbarium 
to which Steele referred disclosed no differences sufficient to warrant 
its separation. Small’s distinction of a straw-colored pappus in V. 
tomentosa is not supported by herbarium evidence. Two sheets so 
labeled in the Columbia herbarium have immature heads which had 
not flowered, and the third, with tawny pappus, is clearly V. 
glauca.
