since been found at Franconia, New Hampshire (W. G. Farlow), 
and at West Newbury, Massachusetts (Miss Haynes). 'The lowland 
specimens bear leaves which are more or less bilobed and therefore 
represent the Nardia insecta of Lindberg. European writers, how- 
ever, do not consider this plant a distinct species at the present time. 
4. LorHozIA CONFERTIFOLIA Schiffn. Oesterr. Bot. Zeitschr. 55: 
47. 1905. Mt. Katahdin, Maine (Cowles Party, 20). Determina- 
tion confirmed by Schiffner. The species is apparently confined to 
alpine regions, where it grows on peaty soil or on stones covered with 
earth. Until the present time it was known from only four European 
localities, three in Austria and one in Switzerland, and its detection in 
New England is therefore of considerable interest. L. confertifolia 
belongs to the ventricosa-group, and its author compares it with L. 
alpestris (Schleich.) Evans and L. Wenzelii (Nees) Steph. It is 
characterized by its densely tufted habit and by the fact that its leaves 
are closely imbricated and concave. Its color is a dull green, more 
or less tinged with brown or red. The leaves are broadly elliptical and 
bifid one third or less with a lunulate to obtuse sinus and broad obtuse 
or subacute lobes. The leaf-cells have small but distinct triangular 
trigones and their walls are otherwise thin though often pigmented. 
In the middle of the leaf the cells average about 23 u in diameter, 
agreeing in this respect with the cells in L. ventricosa but being con- 
siderably larger than those of L. alpestris. ‘The Maine specimens 
agree closely with those distributed by Schiffner.

The Chocorua specimens were determined by Schiffner. L. longidens 
was first recorded as a North American species by Macoun, who 
found it on wet rocks in the Smoky Mountains of Cape Breton, Nova 
Scotia. It has a wide distribution in Europe and has also been col- 
lected in Siberia. Schiffner considers it one of the most clearly marked 
members of the ventricosa-group, but Stephani looks upon it as a 
simple synonym of L. ventricosa. The writer is disposed to accept

lowing are here recorded from New England for the first time.
