considers this species to be the same as Marsupella emula Paitin 
with which opinion Prof. V. Schiffner mentions that , he is in agree- 
ment. Lindberg had mistaken some other plant for Angstrom’ 8, as

AneEvura incurvata (Lindb.).—On moist loamy gr a Pease 
Dene, Berwickshire, June, 1901; female plant. Determined by 
W. earson. ‘This critical species was first described by 
Lindberg i in Musci Scandinavici, and has recently been investigated. 
by Prof. Schiffner in “ Lotus,’ 1900. In this latter ie td there

are full remarks on the comparative differences between this pla ant 
and the other European specie is ° also oe in his 
Hepatice Europea Easiccata, Series is 18 
I., issued last year. It 
loicous, as with A. pinguis, but is more closely Bare to A. 
multifida and A. sinuata according to Prof. Schifiner. The calyptra 
is very rough; the frond varies from bei ing ‘nearly simple to much 
branched and is channelled, semilunar in section, and five cells 
thick, the outer cells of the dorsal side being almost as large as the 
inner cells. The main stem has a one-celled margin, which is 
more distinct on the branches when it is one to two cells broad. 
This species has been found in Austria, Germany, and Scandinavia, 
ae when better known will no doubt be found in other parts of 
tain.
