the name was quoted from time to time in synonymy. Meanwhile 
the species which Schleicher called J. gracilis was published as new 
by Lindenberg under the name J. attenuata, and it is by this specific 
name that it ought now to be designated. L. attenuata is known in 
New England from Maine, New Hampshire, Vermont, and Connec- 
ticut, and ought surely to be expected in Massachusetts.

Mountain, Franklin County, Maine (Chamberlain & Knowlton). New 
to New England but recently recorded from arctic America (Green- 
land, Ellesmere Land, and North Lincoln) by Bryhn.! L. Baueriana 
was proposed by Schiffner to include plants which were formerly con- 
sidered connecting links between L. Floerkii and L. lycopodioides. 
Although so recently published it has already received wide accept- 
ance in Europe, where it has an extensive distribution. It agrees with 
its nearest allies in having distinct underleaves and in developing a 
cluster of teeth or cilia near the postical base of each leaf. It differs 
from L. Floerkii in the fact that its leaves usually have four lobes 
instead of three, some of the lobes at least being tipped with bristle- 
like teeth, instead of being uniformly blunt. hese peculiarities it 
shares with L. lycopodioides, but the latter species is distinguished by 
its larger size and by its crispate leaves commonly broader than long. 
L. Baueriana is further characterized by producing an abundance of 
gemmae, these bodies being very rare in most species of the barbata- 
group. Another very close relative is L. Hatcher? (Evans) Steph. 
of antarctic regions, a species which also reproduces itself largely by 
means of gemmae. According to Loeske the two species are prob- 
ably synonymous, and he unites them under the name Barbilophozia 
Hatcheri Loeske In view, however, of their wide geographical sep- 
aration it seems quite justifiable to keep them apart until their ranges 
of variability are better known, more especially since no species of 
the barbata-group are known from intermediate regions. For fur-
