Notes:

Philonotis is recognized, in part, by the habitat, usually in exposed to shaded seepy or permanently wet sites. The plants are generally small, stems lack a hyalodermis, subfloral innovations are present, leaves mostly 2 mm long or less, alar cells undifferentiated or weakly so, seta elongate, and capsules furrowed when dry, peristome well developed and usually persistent. A widespread genus of wet habitats with far fewer than the180 species ascribed to it. In the Neotropics numerous species described or reported; more than 40 species recorded for the tropical Andes; the actual number of species is probably on the order of 25. In the tropical Andes Philonotis is mostly found exposed on soil or rock usually associated with wet habitats such as river banks or seepy habitats in lowland to montane areas, and boggy sites at higher elevations. Philonotis is much in need of revision in the Neotropics. The treatment by Dismier (1910), although very much outdated, is still a useful reference; the keys are partially functional. The recent treatments for Mexico (Griffin 1994) and Central America (Allen 2002) include several of the Andean species. The present concept of Philonotis includes the genus Bartramidula.

 

Philonotis es un  género ampliamente distribuido con casi 180 especies. En el Neotrópico puede haber unas 30-40 especies luego de una revisión minuciosa. Aproximadamente 20 especie o menos se encuentran en los Andes tropicales. En los Andes tropicales Philonotis se encuentra principalmente en hábitats expuestos sobre suelo o rocas, en las tierras altas también sobre taludes de ríos, manantiales y pantanos; en tierras bajas generalmente está restringido a arroyos y taludes de ríos. Philonotis se reconoce por su pequeña estatura, hialodermis ausente en los tallos, presencia de ramas fasciculadas cortas, células de la lámina por lo general claramente papilosas, proyectándose en los extremos (rara vez en el centro del lumen), células alares indiferenciadas o débilmente diferenciadas, setas largas y cápsulas acanaladas en seco, peristoma bien desarrollado y generalmente persistente.
