Common Name Regnell's Bulbophyllum [Swedish Orchid Collector in Brazil 1800's]

Flower Size 1/4" [.65 cm]

Found in southeastern Brazil on moss covered scrub on wind-blown, exposed mountain ridges at elevations around 1500 meters as a mini-miniature sized, cool growing epiphyte with a tough, woody rhizome giving rise to clustered, squat, almost round pseudobulbs carrying a single, oblong, deeply keeled, dark green, stiff leaf that blooms in the late summer and early fall on a stiff, basal, ascending then abruptly descending, 10" [25 cm] long overall, rachis at a right angle to the peduncle, to 4.4" [11 cm] long, successively 1 to 2, several flowered inflorescence carrying alternate, small, bilaterally compressed flowers.

This species is very similar to B. napelli, however, it is distinguished by having petals with an acute apex and by presenting small orbicular projections at the base of the lip, which are folded over the ventral surface of the lip and have crenate margins.

Synonyms Bulbophyllum napelloides Kraenzl. 1911; Bulbophyllum sturmhoefelii Hoehne 1950; Didactyle regnellii Barb.Rodr 1882
