Flower Size 1" [2.5 cm]

Found in southern Vietnam in Evergreen broad-leaved humid forests on granite at elevations of 1000 to 1200 meters as a mini-miniature to miniature sized, cool growing terresrial with a short creeping rhizome-like, flexuous stem, composed with several cylindrical or fusiform, oblique, dull violet to pale brownish-violet, fleshy, smooth, ascending pseudobulbs sympodially arising from the oblique apical part of each other, and carryiing a single, apical, sessile, joined to apex of petiole-like apical part of pseudobulb, which is terete, fleshy, erect to oblique, narrowly cordate, somewhat fleshy, pale gray-violet, mottled with darker, unclear, dull violet spots, with prominent median vein, acute, straight along the margin leaf that blooms in the later summer on an erect, arising from pseudobulb apex, sheathed at the base, erect slender peduncle thin, glabrous, 2 to 4" [5 to 10 cm] long, dull purple-violet to pale purple-brownish, provided with 1 to 4 persistent, membranous, well distant, narrowly triangular, acute, sterile bracts; rachis (0.8)14(4.5) cm long, straight, purple-violet, spirally arranged, lax, 1 to 5 flowered inflorescence with horizontally directed, yellowish membranous to papyraceous, narrowly triangular acuminate, longer than the ovary floral bracts.

"The new species differs from others in its broad flat or slightly concave lip having no prominent keels or any other ornamentations. In general habit, our plant solely resembles the Himalayan N. cordifolium (Lindl.) Bl., but is distinctly different in many features, including the pedicel and ovary hairy with scurfy hairs (vs. glabrous pedicel and ovary), lip pure white with 3 purple-violet nerves (vs. lip uniformly pale yellow), lip margin wavy or crispy (vs. entire, straight lip margin), prominent falcate lip side lobes (vs. rudimentary, triangular, tooth-like side lobes), broadly ovate, apiculate median lip lobe with 3 hardly visible low finely verruculose keels (vs. broadly rectangular, emarginate median lobe with 3 lamellate, dent-like, tall keels) and finely verruculose spur (vs. spur with a smooth surface).
