    Abstract

    Further discoveries on Bulbophyllum section Beccariana is presented here. First, a new species from the central part of Kalimantan (Indonesian Borneo), Bulbophyllum sapathawungense, is described and illustrated. It resembles two morphologically similar, B. bruneiense J.J.Verm. & Lamb. and B. ecornutum (J.J.Sm.) J.J.Sm., but the new species differs in having a 3-lobed labellum with narrow, uncinate side-lobes, and the pollinarium lacks a stipe. Second, a new country record for is also presented for Bulbophyllum abangjoei Rusea, Besi & Pungga, a previously Sarawak endemic. Information on distribution, ecology, and phenology is provided.
