Asplenium pahli Salgado, sp. nov.
Diagnosis:—Asplenium pahli and A. anisodontum have a proliferous rachis but differ in the pinna shape and serration. A. pahli differs from A. caudatum, A. falcatum, A. gueinzianum, A. planicaule and A. polyodon in the proliferous rachis, the pinna margins being irregularly serrate, sinuses of different depth and width, fewer sori distant from the costa, not contiguous, and straight or slightly falcate.
Distribution and ecology:— Island of Leyte, Central-Eastern Philippines. A terrestrial species growing on the eastern slopes of the Leyte Cordillera, at 500 m elevation, in lowland tropical evergreen rainforest. Climate warm and humid; rainfall evenly distributed throughout the year (Pagasa 2020).
Etymology:— The species epithet honors Brother George Pahl, FSC, Ph.D., an American biologist and university professor who taught, mentored, and inspired thousands of students in the United States and the Philippines during his teaching career spanning more than 50 years.
