whitish pubescence of curled, often deflexed, hairs of seri or 
medium length, which are also found on the petioles, and so 
times extend along the under side of the midrib and the interal 
veins of the radical leaves. On the higher part of the stem, 
especially on the inflorescence, a greater or less number of stalked 
glands and of spreading pilose hairs is usually intermingled with 
oe shorter ron i the long hairs occasionally occurring right 
wn to the stock. 
"The cai shamiboritis feature, however, is haan! the 
calyx. This is relatively — its tube, as recorded by M. Briquet, 
being 4 mm. long, with the broad upper lip 3 mm., and the 
bidentate lower one 5. mm. in length. These dimensions are not 
constantly reached in the dwarfer forms, in which the teeth 
generally show rather less development than in the taller plants, 
ut they are sometimes exceeded when the ante: has become 
enlarged in fruit, the extreme length in one of m cimens being 
over 11mm. The spinous teeth of both lips, oiratiae with their 
strong nerves and coriaceous texture, are very remarkable after the 
period of flowering; but the calyx-hairs are still more so, an 
furnish the most important character of the Verbenaca group. 
This character is the presence of a number of long, berg sig 
hairs, resembling those of the stem, which abound on the pedicels, 
tte n numbers on the calyx, especially on the to ana and 
axe eonspieuotsly abundant round the interlabial sinu In 
addition to these hairs some stalked glands may also be ere and 
these caimananath along the nerves of the upper lip. 
This pilosity of the calyx readily separates these plants from 
the small-flowered forms of S. pratensis L., in which it is absent, 
and replaced by a comparatively short pubescen ce. S. pratensis 
is further distinguished, not only by the glandular upper lip of 
he corolla but by the less strongly-nerved and coriaceous calyx, 
ess spinous and upper lip more recurved. A nnn 
onttarat pubescence, too, not only clothes the stem and petio 
but covers the under leaf-surfaces, and some of the hairs er 
glandular, a distinct scent is imparted to the foliage, which in the 
Verbenaca forms is wanting.

THE pean of the present note is to draw attention to some 
little-known characters of Barbarea stricta, and to record what we 
have ausertannel as to its distribution. The material examined
