new plants on it in a distance; roots loosely pauci-pluri-fasciculate at 

 nodes near the stem, filiform, often with root-hairs. Stem erect, or 

 ascending, slender, gracile, 1 -6V2 cm long and glabrous below the 

 leaves, but 7V»— 20 l /s cm long (including the raceme) and pubescent 

 with spreading glandular hairs above the leaves, provided with 2 thinly 

 membranaceous adpressed sheaths at the base. Leaves 2, oppositely 

 approximate (the superior one usually somewhat smaller), patent, situated 

 in the lower portion of the stem, elliptico-ovate to orbiculato-ovate, or 

 subdeltoid-ovate, obtuse or acutish at the apex, broadly truncate and 

 sometimes very shallowly subcordate below, triangularly and very slightly 

 produced at the sessile base, entire and crispulate on margin, mem- 

 branaceous, glabrous, green, often albescent along the main nerves on 

 the upper surface, paler beneath, 12—38 mm long, 11—29 mm broad; 

 main nerves 3 and moreover with 1 or sometimes 2 nerves between 

 them and 1 nerve in their outsides, the outer one with an external 

 branch; veinlets delicate and loosely anastomosing; reduced leaves minute, 

 squamiform, 4—9 or sometimes 12, very loosely disposed on the stem 

 between the leaves and raceme, adpressed or erect-patent, or spreading, 

 subulate or linear-subulate, long-acuminate, viridescent, thin, glabrous, 

 1-nerved, Vj 2 —b mm long. Raceme erect, loosely 6 —21 -flowered; rachis 

 filiform, straight, or subflexuous above, 2%— 7 cm long; bracts (Pig. II, 

 1—2) erect-patent, adpressed to and apparently shorter than the pedicel, 

 subulate, acuminate, 1—3 mm long. Flowers small, viridescent with no 

 trace of purple; pedicels erect- patent, gracile, puberulent or glabrous, 

 2—5 mm long. Perianth erect-patent or recurvo-patent, equal in length, 

 thinly membranaceous, 1-nerved, reflexed on margin, 2— 2V3 mm long. 

 Sepals: the superior one (Fig. II, 3) oblong-lanceolate, obtuse or acutish- 

 obtuse; lateral ones (Fig. II, 4) similar but slightly oblique in form. 

 Petals (Fig. II, 5) linear, very obtuse. Labellum (Fig. II, 6—7) 2— 2 l /r 

 times the length of the perianth, narrowly obovato-cuneate, gradually 

 attenuated below and without basal teeth, obcordate with oval or oval- 

 ovate lobes (rounded at the apex and entire or obscurely crenulate on 

 margin) and closed sinus above, rarely obcordato-cuneate (Fig. II, 8> 

 with an open sinus and divergent oval lobes, often pointed with a 

 minute depressed-deltoid or depressed-rounded projection in its bottom 

 between lobes, 5— 6V 3 mm long, 2-4 mm wide in the upper broad 

 portion, the median nerve thicker; veins which run into the lobes branched. 

 Column l 2 /3-— 2 mm long, straight; clinandrium deeply concave, the doi\*nl 

 edge obscurely crenulate; anther elliptical-ovate; rostellum broadly del- 

 toid-ovate; stigma rounded. Ovary oblong or obconico-oblong, glabrous. 

 2— 2 l / 2 mm long. — Nom. Jap. Ao-futabaran (T. Makino), Futaba-
