Bolbophyllum Lobii; folio petiolato obovato-oblongo coriaceo, pedun- 
culo unifloro folio breviore, pedunculo nudo unifloro folio breviore, sic basi 
subglanduloso e bracteis squamaeformibus cucullatis falcatis subglandu- 
losis erumpente, sepalis oblongis acutis lateralibus falcatis, petalis con- 
formibus minoribus reflexis, labello longe unguiculato cordato ovato acuto 
canaliculato apice recurvo. Lindl. 
Rhizome creeping, rather stout, 5 to 7 mm in diameter, with 
numerous simple or rarely branched roots which are 1 to 1.5 mm 
in diameter. Pseudobulbs pyriform-cylindric, asymmetrically 
curved, remote, rugose, monophyllous, sessile, 4 to 4.5 cm long, 
1.7 to 1.9 cm in diameter at the widest portion near the base. 
Leaves oblong-elliptic, acute, coriaceous, rigid, about 12 cm long, 
4.6 cm wide; the petioles about 3 cm long. Scape arising from 
the side of each pseudobulb, its base sheathed with imbricated, 
lanceolate, membranaceous bracts, which are 2.2 to 2.8 cm long; 
the peduncles provided with bracts, which are 1.5 to 2 cm 
long. Pedicellate ovary primuline yellow and minutely spotted 
with dark purplish brown, 4.5 to 5 cm long, the ovary conspic¬ 
uously ridged. Flowers showy, the largest of all known Phil¬ 
ippine bulbophyllums, solitary, 7.5 to 8.5 cm across. Lateral 
sepals strongly falcate, lanceolate, gradually narrowed to the 
acute apex, 7.8 to 8 cm long, about 2 to 2.3 cm wide at the widest 
portion near the base, 13-nerved, the anterior portion circinate. 
Dorsal sepal greatly elongated, narrowly lanceolate, gradually 
narrowed to the acute apex, about 9.5 cm long, 1.5 cm wide at 
the widest portion near the base, 11-nerved. Petals similar to 
the lateral sepals, 7.1 to 7.7 cm long, 1.1 to 1.2 cm wide at the 
widest portion near the base, 9-nerved. Labellum triangular- 
lanceolate, strongly recurved, fleshy, mobile, acuminate, cordate
