''. As stated in the book ''The Orchids of the Philippines'', synonyms of ''Bulbophyllum weberi'' include ''Bulbophyllum baucoenese'', ''Cirrhopetlumalum baucoense'', and ''Cirrhopetalum weberi.'' It is endemic to the Philippines. The common name of ''Bulbophylum weberi'' is Weber's bulbophyllum because of its discovery by C.M. Weber, the man that took the type specimens. Ames named it ''Bulbophyllum weberi'' in ''The Philippine Journal of Sciences'' in 1912. Dr. Karl Senghas assigned it to the genus ''Cirrhopetalum'' in ''Schlecter's Orchidean'' in 1983.(Cootes, Banks,& Titmuss., 2001.,pg.56) This orchid is yellow in color and has dark red and brown spots. It grows upright and sympodial. It usually has around ten blooms. The petals are triangular and it grows on the base of tree trunks at elevations of about 1500 meters.(Cootes,J., Banks.P.D.,& Titmuss,D.2001.,pg.56) Dorsal sepal of B. weberi was entirely yellow with purplish blotches, also on long multicellular hair at apical part. In B. weberi, both surfaces of the dorsal sepal were smooth, with a few minute sunken unicellular (situated in pairs) or bicellular trichomes in small depressions. The apical part of the sepal abaxial (outer) surface bore stomata, placed also in the depressions. The residues of secretory material were detected on the outer (abaxial) slightly rugose surface, also on trichomes and stomata. Close to the hair, flat cells were transformed into conical papillae with striate wall pattern, also on apical hair. (Kowalkowska, A.K. Turzynski, S. Kozieradzka-Kiszkurno, M. et al. 2017)
