Authority: Buck, William R. 1987. Bryostephane Steereana: A Collection of Bryological Papers Presented to William Campbell Steere On The Occasion of His 80th Birthday. Mem. New York Bot. Gard. 45: 1-749.
Discussion:Thirty fragments, 1.45-1.56 m , similar under the dissecting microscope to branch and stem fragments of Drepanocladus, but the characteristic long filamentous rhizoids were visible upon dissection. The narrow, long acuminate leaves of the fossil suggest var. falcatum (Brid.) Monk. Fig. 4a-c.
