Musci bor. Am., but without locality. Judging from his her- 
barium, it must be either the specimens numbered 60 and 65, sent 
him by Lesquereux, collected at Lancaster, Ohio, in 1849, oF 
those from Columbus, Ohio, May, 1861, also collected and sent to 
him by Lesquereux ; probably the latter, for the second set of . 
these exsiccate were put up by Lesquereux, all the duplicate 
packets bearing his German figures to correspond with the num- 
bers on the tickets. These, too, were compared with the type, and 
they show the same differences as Dr. Cassell’s, even more accent 
tuated. The pedicels are much longer, more exserted and flexuose, 
the capsules narrower and longer with a longer beak and neck, 
leaves shorter and more spreading. With the higher powers the 
walls of the cells on the back of the vein are more thickened than 
in the type, and the margins are subserrulate. These spores are 
a little smaller and roughened in the same way as the type. It 
will be seen, then, that there is not in Sullivant’s cover of B. 
B. flexuosa an exact match for the type from Geneva. His spec’ 
mens all match B. Sudlivanti Austin, and the specimens in be 
herbarium which match the types are in the cover of B. Beyricht- | 
ana, which we have shown he figured in the Supplement to the 
Icones, plate 15 as that species. 
That B. flexuosa and B. Sullivanti are very closely allied and | 
probably grade into each other is proven by the above compari: 
sons, but that the differences between them are noticeable a 
shown by the several names which they have given rise to. | ate
