Abstract
A new species of orchid, Pseuderia samarana Z.D. Meneses & Cootes (Orchidaceae: Podochileae, Eriinae) from Samar Island, Philippines is described and illustrated. This is also a new generic record for the country. It is distinguished from other known species by the combination of the following characters: relatively smaller lanceolate leaves, minutely cuspidate bracts, 2-flowered raceme borne on short peduncle, narrower labellum, and entire clinandrium margins. Notes on its habitat and ecology, distribution, conservation status, and comparison with other closely related New Guinean speciesare also presented.

Pseuderia samarana Z.D. Meneses & Cootes, sp. nov.
Diagnosis. Pseuderia samarana shares similarity
with both P. frutex and P. floribunda but the new species
significantly differs in its 2-flowered inflorescence (vs. 3‒
5-flowered in other two species), much narrower labellum
(2.5 mm wide vs. 4.5‒5 mm) and entire clinandrium margins
(vs. serrulate in P. frutex and dentate in P. floribunda).
....
Etymology. This new orchid species is named after
the type province, Samar. The province forms a large
partion of the Samar Island Natural Park. It has several
rolling limestone formations which supports a distinct
forest type. Samar also houses the headquarters of the
park’s Protected Area Management Board which is the
governing and managing office of the natural park
