Bulbophyllum parex J.Alvarez-Diaz & J.S.Moreno sp.
nov.
Bulbophyllum parex is morphologically closest to
Bulbophyllum bidentatum (Barb.Rodr.) Cogn., from which
it differs in having lanceolate petals with a ciliate margin
(vs. ovate-lanceolate petals with a lacerate-ciliate margin),
the labellum with slightly ciliate lateral lobes (vs. to entire lateral lobes), and the middle lobe oblong-elliptic (vs.
linear-ligulate).
Etymology: The specific epithet, parex, is given in
gratitude to Parex Resources company, for their financial and
logistic support in the process of studying and publishing
the new species.
