Status: Native
Synonyms:
Pylaisiella polyantha (Hedwig) Grout
Leskea polyantha Hedwig
Pylaisia polyantha has leaves that look much like those of Homomallium mexicanum. The leaves of P. polyantha have
longer laminal cells and fewer alar cells than H. mexicanum. In addition, and easiest to note in the field, the capsules
of P. polyantha are erect while those of H. mexicanum are nodding. The endostome of P. selwynii is adherent to
the exostome, while it is free in P. polyantha.
