Rhizome ascending or erect, 1.5-2.5 mm thick (excluding densely matted roots and adherent stipe bases), clothed toward apex with numerous yellowish-brown, delicately subclathrate, distantly glandular-denticulate scales mostly 2-3 mm long, these with contorted hairlike tips. Fronds rather few, tightly clustered, very stiff" in texture, 7-15 cm long, nearly exstipitate, nearly glabrous; blades 2-2.5(-3) mm broad, acute at apex, the costa prominent on adaxial side and ffat beneath, the blade more or less triangular in cross-section; veins immersed and not visible without specially clearing the tissues, simple or occasionally forked and casually anastomosing, the free tips not reaching the margins, ending in obscure adaxial hydathodes. Coenosori mostly 2-6 cm long, immersed in a deep slit, the edges of which conceal the young sporangia and are pushed apart as the sporangia develop. General Distribution. Greater Antilles, Guadeloupe, and continental tropical America from Mexico to Colombia and Venezuela.Distribution in Puerto Rico. Known from but two collections. Ciales: Upper SE slopes & summit of Cerro Rosa, 26 M a r 1988, Proctor 44599 (SJ); Jayuya: NW ridge of Monte Jayuya, 24 Mar 1984, Proctor 40358 (SJ).Habitat. Epiphytic in montane mossy forest at a high elevation (1250-1300 m), very rare. General Distribution.
