Perichaetial leaves broadly ovate-lanceolate, narrowly acuminate to subulate, sometimes flexuose to secund, same size as stem leaves; costae short to long excurrent, hairpoint pellucid, sometimes finely spinose; laminal margins recurved, smooth to finely serrulate; distal and median laminal cells similar to stem leaves, proximal laminal cells lax, wider, rectangular, 2-4:1, 35-115 × 12-25 µm, sometimes somewhat hyaline. Specialized asexual gemmae absent. Sexual condition autoicous; antheridia terminating axillary leaf buds. Capsule terminal, 425-750 µm.
