Bryum rhizoblastum Cardot & Broth.
NOTES
A poorly known Falkland Islands endemic characterized by Bryum - type laminal areolation, lanceolate leaves and a weak costa.The epithet suggests a similarity to juvenile innovations that arise early from rhizoids, which in many species show differences from leaves developed later.The species is most similar to Bryum pabstianum but is tentatively accepted pending further work.
