 at the apex, broadly truncate or truncato-subcordate and in centre very 

 slightly produced at the base, minutely crispulate on the entire margin, 

 glabrous, membranaceous, 13—25 mm long, 10—31 mm wide; main 

 nerves 3, with a vein between main nerves and in their outsides; 

 veinlets loosely anastomosing; reduced leaves none or only one, squami-

 3— 9-flowered, 3— 57 2 cm long; rachis gracile, often subflexuous; bracts 

 small, patulous or erect-patent, distinctly shorter than pedicels, ovato- 

 subulate, membranaceous, glabrous, 1 -nerved, l'Va - 5 mm ' on g- Flowers 

 small, olivaceo-purpurascent ?; pedicels gracile, erect-patent, glabrous or 

 subpuberulent, 3—8 mm long. Perianth equal in length, obtuse, mem- 

 branaceous, 1-nerved, 3 — 4 mm long. Sepals reflexed; the superior one 

 oblong-lanceolate; lateral ones similar, but hardly oblique in form. Petals 

 slightly broader than sepals, oblong. Labellum twice as long as the 

 perianth, flabellato-obcordate with ovato-oval or oval-elliptical rounded- 

 obtuse often subcrenulate divergent lobes, with a minute depressed- 

 deltoid point in the bottom of open sinus, broadly cuneate below and 

 shortly attenuated at the base, on each side near its base furnished with 

 a small (IV3- IV9 mm long.) obovato-elliptical or subspathulato-oblong 

 obtuse tooth (turned upwards and parallel to the column). 5 — 6V2 mm 

 long, 4 l / 2 — 6 mm broad, flabellately veined, the median nerve thicker. 

 Column 2— 2 l / 2 mm long, straight; clinandrium deeply concave, the dorsal 

 edge thin and pauci-crenulate; anther lato ovate, obtuse; rostellum 

 broad; stigma roundish. Ovary obovoid or obovoid-oblong, glabrous, 

 2—3 mm long. - Nom. Jap. Miyama-f utabaran (nov.). — Japan:

 shiro: Mt. lide (G. Nakahara! Aug. 1904). — This species is found in 

 sub-alpine shady part of mountains. It differs apparently from Listera 

 puberula Maxim., which has the patulous perianth, ovate sepals, linear- 

 petals, linear-cuneate labellum 3— 4-times as long as the perianth, and 

 arcuate column; and also from L. pinetorum Lindl., which has the lato- 

 deltoid leaves, very short raceme, larger flower, connivent perianth, ovate 

 sepals, linear petals, and long and arcuate column. It approaches very 

 much to L. convallarioides Nutt., but the latter has the orbicular-ovate 

 obtuse leaves, cuneato-oblong emarginate or shortly 2-lobed labellum, 

 and slender column. It is also distinguished from L. EschschokUina 

 Cham., which bears the foliaceous bracts subequal to pedicels, angustato- 

 lanceolate acute perianth, narrower labellum, and the elongate column. 

 L. japonica Bl. is easily distinguishable from my species by its deltoid 

 leaves and entire (not cleft) labellum.
