Acuteleaf Small Limestone Moss

Seligeria acutifolia is known from only a few localities along the hyperoceanic West Coast. It differs from similar species in having sharply differentiated perichaetial leaves and a short, stout seta. The capsules are usually shortly exserted or sometimes emergent.

Plants delicate, light green. Leaves broadly linear to lanceolate, shortly subulate from broad base, acute; costae percurrent; margins entire; leaf cells (1-)3:1; perichae-tial leaves subulate from sheathing base, abruptly differentiated. Seta 1-1.5 mm, straight, stout. Capsule hemispheric to broadly ovate, as long as broad, widest at mouth, peristome of 16 well-developed teeth; columella immersed. Spores 12-14 µm.
