L. alpestris lias been collected only at Oneota, on high flat 
narrow rock ledges on the north side of the cliff. Near by the 
perpendicular wall was covered with great green patches of 
fruiting L. barbata and L. Lyoni, while the very small rock 
crevices in the more open places were outlined with Scapania 
curta and Cephaloziella. 
Only one station was found for L. bicrenata along a well 
beaten path close to the edge and at the top of the cliff below 
the dam at Thompson, Minnesota. It grew in full exposure to 
the sun on rather dry thin earth on rocks. This was in full 
fruit September 26, 1909. Collected also in the same locality 
in 1910 and 1911. 
L. excisa was observed only at Chester Creek, and Fairmount 
Park, Duluth, Minn., in both instances at the top of the cliff by 
the upper falls, near the boulevard. At Chester Creek it grew 
on a half buried upturned stump spreading out on the loose 
sandy clay and was in splendid fruit July 29, 1909. It has a 
vivid green color and is a larger plant than L. bicrenata } re* 
sembling in the field a stunted form of L. Lyoni.
