Whole plant 16—19 cm in height, Rhizome subterranean, creeping, 

 filiform; roots filiform, with root-hairs. Stem erect, slender, glabrous 

 below the leaves but above them pubescent with patent short glandular 

 hairs including the rachis of the raceme, with 2 membranaceous ad- 

 pressed sheaths at the base. Leaves 2, placed in the middle of the 

 whole plant, oppositely approximate, patent, orbiculato-subreniform, obtuse 

 or acutish at the apex, broadly truncato-subcordate below and very 

 slightly produced at the sessile base, entire and more or less crispulate 

 on margin, membranaceous, glabrous, 18 — 25 mm long, 25—30 mm broad. 

 7-nerved, the outer nerve with an external branch; reduced leaves few 

 (about 2), loosely disposed on the stem between leaves and raceme, ad- 

 pressed or erect-patent, subulate, acuminate, squamiform, glabrous, 

 viridescent, about 2 l \.> mm long. Raceme erect, loosely about 11 -flowered, 

 about 4 — 5 cm long; rachis filiform, straight; bracts erect-patent, appa- 

 rently shorter than pedicels, ovato-subulate, deltoid-subulate, or lato-ovate, 

 acuminato-acute, membranaceous, 1-nerved, P/a — 2 mm long. Flowers 

 small, luteo-viridescent?; pedicels erect-patent, gracile, pubescent, about 

 3 1 / 2 - 4 mm long. Perianth equal in length, obtuse, membranaceous. 1-nerved, 

 about 2 l /3 mm long. Sepals: the superior one ovato-lanceolaie; lateral ones 

 somewhat oblique in form, lanceolate-oblong. Petals linear. Labellum twice 

 as long as the perianth, lato-linear below, divergent with 2 short-oblong 

 obtuse and slightly oblique lobes above, with a minute point in the 

 bottom of the open sinus, the median vein thick, veins which run to the 

 lobes 3 and simple or sometimes forked; basal teeth very minute and 

 obsolete. Column about 2 mm long; anther lato-ovate, obtuse and very 

 shortly bifid at the apex; rostellum orbicular: stigma roundish. Ovary 

 oblong, glabrous, about 2 mm long. — Nom. Jap. Takane -futabaran

 a resemblance to Listera pnberula Maxim, from Western China, but 

 differing from it by the form of leaves and sepals, and the length of the 

 labellum. It comes also near to L. Savatieri Maxim., but also differs 

 from the latter by the form and position of leaves, and the form of the 

 labellum.

 Whole plant 11—22 cm high. Rhizome short, ascending or erect; 

 roots filiform, with root-hairs. Stem erect, slender, glabrous below the 

 leaves but above them pubescent with patent glandular hairs including 

 the rachis of the raceme, provided with short, adpressed. membranaceous 

 and remotely placed two sheaths at the base. Leaves 2, oppositely 

 approximate, situated in the middle of the whole plant, patent, sessile,
