An epiphyte; stem 3 ft. in circumference; young branchlets elongated, tapered to the apex, ribbed, glabrous. Leaves elongate-oblong, gradually and obtusely acuminate, rounded or obtuse at the base, 4–6 1/2 in. long, 1–1 1/2 in. broad, entire, shining above, dull and glabrous below; midrib flat above, prominent below, gradually tapered to the apex of the blade; lateral nerves about 10 on each side of the midrib, diverging from it at an angle of about 75°, arcuate, looped near the margin, prominent below; tertiary nerves reticulate; veins forming a close network below; petiole about 1/2 in. long, glabrous, sulcate above; stipules early caducous, very small, acute. Receptacles borne in fascicles on very short leafless lateral branchlets on the main stem, pedunculate, subglobose, about 1 3/4 in. in diam. when ripe, shrinking to 1 1/4 in. when dry, with very thick walls, cordate at the base, strigillose-pubescent; peduncle 1 1/4 in. long, recurved, stout, puberulous. Basal bracts caducous, from a sketch by the collector more or less lanceolate and about 7 lin. long, probably membranous. Ostiole small and pore-like, with the bracts all descending into the receptacle. Male flowers rather long-pedicellate, with a solitary obtuse anther. Female flowers pedicellate; stigmas papillose.
