brum, ad apicem biconnutum. Anthera glabra. Pollinia 4, 
subaequalia. Capsula ellipsoidea, valde saccata, 6 ad 6.5 cm 
longa, 1.7 ad 1.8 cm in diametro. 
A very coarse herb, 20 to 60 cm high, recalling Sarcanthus 
pachyphyllus Ames. Roots elongate, brown, glabrous. Stems 
terete, coarse, very rigid, usually erect, sometimes curved, al¬ 
together concealed by the tubular leaf-sheaths, 1.2 to 1.5 cm in 
diameter. Leaves distichous, ligulate, 16 to 39 cm long, 2.3 to 
3.5 cm wide, very rigid, very thickly leathery, falcate-decurved, 
in texture approaching those of Sarcanthus pachyphyllus, 1.5 to 
3.5 cm distant, unequally bilobed at the apex with obtuse lobes, 
channelled through the middle (when dry very coriaceous and 
never nerved), very rugose. Peduncles erect, rigid, 13 to 14.5 
cm long, 4 to 5 mm in diameter, glabrous. Inflorescences 
in the upper part of the peduncle, racemose, 10- to 14-flowered, 
erect. Pedicellate ovary white, 2 to 2.5 cm long, rigid, glabrous, 
twisted at the base. Bracts of the inflorescence squamiform, 
short, ovate, cucullate, about 3 mm long. Flowers fragrant, 
fleshy, firm, 2.2 to 2.4 cm across, 3.2 to 3.3 cm long. Sepals 
shortly clawed. Lateral sepals ovate-elliptic, obtuse, about 1.5 
cm long, 7 mm wide. Dorsal sepal ovate-oblanceolate, obtuse, 
about 1.6 cm long, 7 mm wide about the middle. Petals oblan- 
ceolate, obtuse, about 1.4 cm long, 5.5 to 6 mm wide. Labellum 
trilobed, conspicuously saccate at the base, about 1.1 cm long; 
lateral lobes small, erect, triangular, about 2 mm high, broadly 
rounded, fleshy, glabrous on both surfaces; middle lobe much 
larger, fleshy, laterally compressed, in outline (when seen from 
above) ovate-lanceolate, rigid, about 7 mm long, prominently 
carinate beneath, very minutely pubescent above, truncate at the 
apex. At the saccate base of the labellum (between the lateral 
lobes) there is a small transverse, suborbicular, deeply concave 
keel as in Staurochilus ionosma. Gynostemium short, stout, 
about 6 mm long, glabrous, 2-horned at the apex with falcate 
horns. Anther glabrous. Pollinia 4, subequal. Capsules ellip¬ 
soid, 6 to 6.5 cm long, 1.7 to 1.8 cm in diameter, prominently 
3-keeled (between each keel there are two shallow ridges).

ing to orchid peddlers, were originally collected from the moun¬

in cultivation in the Bureau of Science orchid house, Miyasaki 
Gardens, and Mrs. Remedios C. Gonzales’s gardens, all in Ma-
