ellipticae, diam. 20-30". Dioicum videtur (floribus masculis 
ignotis). Plate XVII. : 
Missouri: Courtney, on wet rocks (B. F. Bush, 1898). 
Much resembling Barbuda unguiculata Hedw. by the habit and the shape 
and areolation of the leaves, but readily distinguished from it by the peculiar 
Structure of the peristome, which is hardly twisted, and by the spores twice 
larger. C. Miiller described a B. cancellata; the peristome of which accord- 
ing to the description must have a similar structure to that of our D. Bushit, 
but the teeth are smooth (likely twisted), and the lid is as long as the capsule.
