the writer’s herbarium and in the collection of Miss Haynes. In 
this way the additional stations cited above were brought to light. 
They show that F. cristula has an extensive range in the eastern 
United States and indicate that it is a species of southern rather than 
of northern distribution.

alata K. Müll.; Rabenhorst's Kryptogamen-Flora 6: 803. 1911. On 
sandstone along the edge of a brook, Simsbury, Connecticut (Miss 
Lorenz, December, 1914). Although this is the first station to be re- 
corded for North America, the species was discovered at Milford, Penn- 
sylvania, in 1908, by G. E. Nichols and reported by the writer as L. 
cuspidata (Nees) Limpr.! It is known in Europe from Great Britain 
and France. The validity of L. alata as a species is not above question 
and there is even some probability that there are intergrading forms 
connecting it with L. cuspidata. At the same time it presents charac- 
ters which usually make its recognition easy, and its known range in 
Europe is decidedly more restricted than that of L. cuspidata, from 
which it is presumably derived. In North America L. cuspidata is 
known only from the Pacific Coast eastward to the Rocky Mountains, 
so that this evidence also, incomplete as it is, would strengthen the 
claims of L. alata for acceptance. 
The differences between L. cuspidata and L. alata are clearly de- 
scribed by both Macvicar and Schiffner? In L. cuspidata the color 
is pale or yellowish green, the leaves are imbricated and bifid about 
one fourth, the lobes are subulate and acuminate, the median leaf- 
cells average about 30 u in length, the perichaetial bracts are bifid 
about one third, with a narrow acute sinus and subulate, acuminate 
lobes, the bracteole is bifid in a similar way to about the middle or even 
beyond, and the perianth is sometimes destitute of wings, although 
narrow wings are occasionally present. In L. alata the color is a 
darker green, the leaves are less closely imbricated and less deeply 
bifid (usually about one fifth) with shorter lobes, the median leaf-cells 
average about 40 u in length, the perichaetial bracts are less deeply 
bifid (about one fifth to one fourth) with a lunulate sinus and broader,
