ABASTRACT
Stenolepia tristis (Blume) Alderw., an element of Malesian region, is newly recorded from Mindanao, Philippines. Meanwhile, it is also a fern genus new to the flora of Philippines. In addition to the background information, some taxonomic notes, line-drawings of detailed characteristics, and photographs of living material, habitat and type specimens are provided.
INTRODUCTION
Botanical field works in the southern Philippines in 2012 revealed an unrecognized fern taxon on Mt. Apo and Mt. Kitanglad, respectively. After reviewing the floras of the adjacent areas or countries and checking the specimens deposited in several herbaria, including MICH, P, PNH, S, TAIF, UC, we concluded this unknown leptosporangiate fern is Stenolepia tristis (Blume) Alderw. It is not only a new record species but also a new record of genus to the flora of the Philippines. In the Philippines, this fern is known to occur only in middle to high mountain areas at elevations ranging from 2,300 to 2,900 m in Mindanao. . . . read more
