Bulbophyllum

Finding

SITF confirms this plant as Bulbophyllum lobbii subsp. boreoborneense (Oct 2026). Identity based on based on the severely reflexed, swept back petals and sepals. The fundamental differences separating these two variants involve petal and sepal Orientation. While the type species subsp. lobbii typically features broadly spreading, flat, or slightly reflexed yellow-to-ochre petals, northern Bornean variants often present tighter, more forward-pointing, or distinctly swept-back (reflexed) lateral segments. Subspecies boreoborneense is also delineated by microscopic differences in the callus texture and the exact curvature of the lip tip compared to the smooth, broader lip found on the standard type species.
