Common Name The Boxy Bulbophyllum [refers to the shape of the flower]
Flower Size 4" [1 cm]
Found in Malesia without locational data as a small sized epiphyte with 2.8 to 4.4" [7 to 11 cm] between each ovoid pseudobulb and carrying a single, apical, erect, obovate, rounded, gradually narrowing below into the petiolate base leaf that blooms on a basal, 2 to 2.4" [5 to 6 cm] long, single flowered inflorescence with a tubular, acute floral bract.
J J Vermeullen states that "Bulbophyllum thecanthum is known from two different sources, both horticultural, viz. Hort. Bogor 985.3.73 (from Ceram), subsequently (in 1988), in cult. Jongejan 2029 and in LEIDEN 930558. More recently, in 2007, Rysy 3 became available for study. The first record dates from before the rise of Bulbophyllum as a source of artificial hybrids. I assume, therefore, that B. thecanthum should, for the purpose of taxonomy, be regarded as a species, not as an artificial hybrid. Its provenance, Ceram, is subject to some doubt, because records at Hort. Bogor are sometimes unreliable. Bulbophyllum."
"Bulbophyllum thecanthum shares the connate lateral sepals with B. hahlianum Schltr., but differs in the porrect (not spreading) petals, the more conspicuously drawn-out lip, and the absence of a small gibbosity on the column-foot, below the stigma. Bulbophyllum gerlandianum Kraenzl. has flowers of a similar shape, but with free lateral sepals"
