(521.) B. Simplex, Kindb. (n. sp.)

Allied to Bryum roseum; differs in the shoots being short, about 2 cm., clavate, the comal leaves smaller, suboval, not cuneate at the base, fainter denticulate, not patent when moist, the cells shorter, nearly uniform, the gquamiform leaves indistinct. Barren.

This species is also distinct from Bryum. Ontariense, Kindb., and Bryum lucidum, Britt. We have not seen American specimens of the true B. roseum.
