L. Nakaharai Makino in Tokyo Bot. Mag. XXVIII. (1914) 156. — A leafless 

 fleshy perennial; rhizome ramose, densely clothed with many thick broad scales and 

 3 cm or less across. Scape simple, erect, thick, terete, glabrous, sparsely scattered with 

 membranaceous bract-like scales, about 2 5 cm long including the raceme. Raceme erect, 

 about 1 2 cm long, secundly densely many-flowered ; rachis thick, glabrous ; bracts ob- 

 long, narrowly oblong, or oblanceolate, obtuse, entire, membranaceous, glabrous, longer 

 than the pedicels; main nerves usually 3, with loose veinlets. Flowers shortly pedicel- 

 late, erect-patent or patent, pale or slightly rosy, about 1 l /j cm long; pedicel erect, 

 gracile, shorter than the bracts, nearly glabrous (very sparingly pilose), about 3 — 4 mm 

 long. Calyx tubuloso-campanulated, 4-fid, membranaceous, dispersedly patently piloso- 

 pubescent externally, glabrous internally but slightly puberulent towards the margin of 

 the lobes, pale, and very slightly rosy above and below, about 7 — 9 mm long; tube 

 usually slightly compressed laterally; lobes erect or slightly erect-patent, about 3 / 4 as 

 long as the tube, acutish-obtuse at the apex, entire, about 3-nerved; the upper 2 lobes 

 somewhat longer and ovato-deltoid; the lower 2 lobes smaller and scarcely shorter, 

 oblong-ovate ; sinuses acuminate, purple at the bottom; main veins about 10, with 

 more or less anastomotic loose veinlets between veins. Gorolla exserted, narrow, slighty 

 arcuate downwards, enlarged above, somewhat contracted above the base, compressed 

 laterally, glabrous internally and externally, bilabiate above with erect lobes, about 1 1 — 

 1 4 mm long ; the upper lip emarginate ; lobes subsquare, rounded-truncate, folded, not 

 ciliated, finely nerved, 4 — 5 mm long; the lower lip shorter than the upper lip, equally 

 3-lobate, broad, retuso-truncate, finely nerved, more or less crispate towards the margin, 

 about 8*/j — 3 mm long; lateral lobes somewhat oblique in form; sinuses closed or 

 subclosed. Stamens didynamous, inserted at the throat, hardly exserted beyond the 

 upper lip, the upper 2 slightly shorter, somewhat shorter than the upper lip; filament 

 filiform, glabrous, about 4 — 5 mm long in those of the upper stamens, but 7 — 8 mm 

 long in those of the lower stamens; anthers close, equal, elliptical, obtuse and villose 

 with white hairs at the apex, deeply bifid with long and very sharply tapering points 

 (which are solid) and villose with white hairs dorsally, dehiscing longitudinally, introrse 

 dorsifixed, horizontal, 2^3 — 2^2 mm l° n £> anther-cells parallel, narrowly oblong. Disk 

 squamiform, hypogynous and anterior, small, thick, ovoid-ellipsoid, flat ventrally and 

 rounded dorsally, 1 i / 2 mm long. Ovary oval-globose, very shortly attenuated at the 

 base, 3 mm long, 2 72 mm across, glabrous, smooth, shallowly one-grooved on each 

 lateral side, 2-celled; style slightly exserted, filiform, glabrous, about 4 3 mm long; 

 stigma capitate, scarcely bilobed.

Nota. "A rare species; it is distinguished easily from Lathraea japonica Miq. by the 

 very thick large scales of the rhizome" sec. Matsumura. — Rhizomatis squamas L. Miquelianae 

 Franch. et Sav. comparare nequeo, itaque nescio an squamae crassiores latioresque characterem 

 ad speciem distinguendam idoneum sistant. Florum magnitudo variabilis (11 — 14 mm) vix vel 

 certe non sufficit et discrimina alia ex descriptione sat ampla non in venire possum.
