necessarily hasty search in literature indicates that neither plant has 
been noticed before in North America. 
1, AGRIMONIA FUPATORIA L. This species is widely distributed 
in the Eurasian continent. It resembles our native 4. gryposepala 
in that the stem and the rachis of the inflorescence are clothed with 
minute glandular puberulence mixed with long, non-glandular hairs. 
It is readily recognized, however, by its commonly more compact 
habit, the lower internodes of the stem tending to be short, thus 
bringing the leaves close together, by its generally smaller leaflets, 
and by the characters of the fruiting calyx. The body of the mature 
hypanthium is rather narrowly top-shaped and measures from the 
base to the point of insertion of the hooked bristles about 5 mm. 
In A. gryposepala the corresponding measurement is about 3 mm. 
and the hypanthium is very broadly turbinate. Miss Fletcher's 
label gives no information as to the circumstances under which the 
plant was found, but the nature of its fruit marks it as a likely subject 
for introduction with wool. 
2. VERBASCUM THAPSIFORME Schrad. "This is a native of central 
Europe, known in Germany as “wild tobacco." It seems a rather 
critical species, but is maintained as a species in nearly all recent 
European floras. It is closely related to V. phlomoides, from which 
it differs principally in its long-decurrent leaves, the wings of the 
stem formed by them extending from the point of insertion of each 
leaf to that of the one below. From V. Thapsus it differs, as does V. 
phlomoides, in its larger flowers (3—4 cm. in diameter), in its spatulate 
and decurrent (instead of capitate) stigmas, and in the large anthers 
(3.5-4 mm. long) of the two longer (inferior) stamens, which are 
inserted laterally on the filament. The smaller anthers of the inferior 
stamens of V. Thapsus are inserted obliquely across the apex of the 
filament. 
According to Miss Fletcher’s label, there was “an eighth of an acre” 
of the plant at Westford when she collected it in September, 1911. 
A fragmentary specimen in the herbarium of the New England Botani- 
cal Club, collected at Georgetown, Mass., by Mrs. C. N. S. Horner, 
may also be referable to V. thapsiforme.—C. A. WEATHERBY, Gray 
Herbarium.
