S. Askenasyi, V. Schmidle. The following is Professor 
Schmidle’s description of this new species :— : 
“The plant barely 2-5 cm. high forms smail tufts Cine 
on stones. In their basal portion they consist of very narrow cells 
generally only 8-10 p broad, which are usually 3-4 times ae 
than broad and either not at all or only slightly constricted at t

veneers widens, and attains in the middle of the stem b

these moreover for the most part suddenly become still ee
