Plants with numerous, large (8- 10 mm. in diameter) stems, leaves 5-10, near the apex of the stems, roots and inflorescences very numerous, forming 40 cm. tall tufts. Leaves distichous, coriaceous and rigid; sheaths short (10-14 mm.), striate lengthwise and finely traversely rugose: limbus shortly (less than 1 cm.) contracted-pleated basally, lingulate-linear (8-12 cm. x 8-10 mm.), obscurely and unequally bilobed apically. Inflorescences single flowered, very numerous, grouped at each internode in much the same manner as in Angraecum multiflorum, in groups of 3-7. in a unilateral series, with the inflorescences developing successively. one new inflorescence per season on the tip of the rachis; peduncle 6-7cm. long. bearing in the back, 4-5 scarious vaginals which covers the first internode and another longer one above the center (10-12 mm.) and loosely tubular; bracts 12-13 mm. long. tubular. loose. Scarious-brown, finely veined, covering about a third of the pedicel. Flowers white, divisions narrow. opaquc and thick, except for the base. Sepals lanceolate-linear (19-22 x 2 mm. basally), attenuate gradually from the base to the acute apex petals narrower, aciculariform (16-18 x 1 mm. basally). Labellum 20-22 mm. long, gutter shaped. very narrow in the basal half. enlarged (3-4 mm.) medially, then attenuate-acute in a long acicular point: spur 7.5-8 cm. long, compressed and slightly wider basally, then filiform and pendent. Column 2 mm. tall. very wide, auricles nearly square; obtuse on both edges; median tooth of the rostellum acicular and short
