A collection Of Splachnobryum rostratum Broth. & Par. from Sierra Leone wit
h exceptionally well-developed, closely spaced peristome teeth clearly exhi
bits a 2:3 haplolepidous peristomial pattern. The relationship of the Splac
hnobryaceae is with the Pottiales rather than the Funariales, as supported
not only by its haplolepidous peristome, but also by its type of stomata an
d pattern of rhizoid insertion.
