284 MINNESOTA BOTANICAL STUDIES. 



26. Eusticliia norvegica C. Muell. 



Entrance to Indian inscription cave below Lamoille, 

 {J. M. H., Oct. 30, 1893 and August, 1894). Also 

 found around Trempealeau mountain, but in each, 

 case only sterile. 



27. Seligeria pusilla B. S. 



Bear Creek, {J. M. H., May, 1890). 



28. Blindia acuta B. S. 



Northern Minnesota, {F. F. Wood, 1891). 



29. Ditlymodon cyliudricus B. S. 



St. Croix Falls, {J. M. H., July 10, 1890). 



Since Lesquereaux and James' Manual assigns 

 D. luridus to Minnesota {see p. 105), the above 

 plant was carefully compared with Reinsch's speci- 

 mens of D. luridus in the National Herbarium, and 

 was excluded from the species because its leaf base is 

 hyaline nearly a third up. In this respect it was 

 found to agree better with Schimper's specimens of 

 D. cylindricus, though the leaves in the Minnesota 

 plant are shorter. 



30. Leptotriclium glaiicesceas Hampe. 



Winona blutfs, {J. M. H., September, 1894). 



31. Leptotricliuoi tortile C. Muell. 



Catholic cemetery bluff {J. M. H., April 26, 1890); Osce- 

 ola Mills, Wis. {J. M. H., July 18, 1890). 



S2. Desinatodon obtusifoliiis Sch. 



Winona bluffs and Laird's spring {J. M. H., May, 1894); 

 Trempealeau Mountain, Wis. {J. M. H., May 17, 1890). 



This moss is very common around Winona. It 

 occurs always on perpendicular shaded sand cliffs. 

 Its fugacious peristome, which falls almost uniformly 

 with the operculum, makes it a very perplexing moss 

 to the beginner. 



33. Barbula fallax Hedw. 



Bluffs near Winona {J. M. H., Sept. 28, 1889). 



34. Barbula imicroiiifolia B. S. 



Franconia {J. M. H., July 16, 1890); Mankato {J. M. K, 

 Nov. 16, 1894).
