--><p><i>Taxiphyllum</i> has stems with small, thick-walled cortical cells, smooth rhizoids in clusters below the leaf insertions usually on the ventral surface of stems, and axillary hairs with one or two, rarely three short basal cells, and one elongate apical cell. The laminal cells are linear-flexuose, or rhomboidal near the apex, and the cell walls are not pitted. The inflorescences occur at the base of stems and branches; the perigonial bracts are small and ovate; the setae are flexuose; the capsules are smooth; and the exostome teeth are bordered and trabeculate.</p>
