,90* j OBSERVATIONS ON THE FLORA OF JAPAN. 147 



at the base ; veinlets inconspicuous ; petiole gracile, pubescent with ascend- 

 ingly patent hairs, shorter or longer than the blade, the longest one about 

 3 cm. long. Verticillasters axillary, loose, 1-3-flowered. Flowers erect or 

 erect-patent, shorter than leaves ; pedicel very short, pubescent, about 

 |-1 mm. long ; bracts setaceiform, pubescent, equal to or longer than the 

 pedicel and situated at the base of it. Calyx obconically tubuloso-campanu- 

 late, obtuse at the base, pubescent with erect-patent few-celled hairs mixed 

 with very minute granular glands externally and ciliated, thinly puberulent 

 above internally, erect-patently 5-fid and somewhat 2-labiate, 7-10 mm. 

 long ; lobes shorter than the tube, deltoid-subulate, sharply spinescent-acu- 

 minate, 5-costate, with accessory veins between costas, very loosely reticulato- 

 venuled in the lobes. Corolla exserted, 2-labiate, densely piloso-pubescent 

 (denser in the upper lip) mixed with thinly dispersed very minute granular 

 glands externally, purple, 14-18 mm. long ; posterior lip erect, as long as the 

 tube, slightly galeate and sheltering the stamens, elliptical to oblong, retuso- 

 rounded or emarginate, entire, ciliated, 7^-9 mm. long, 4-6 mm. wide ; 

 anterior lip horizontal and patent, about as long as the posterior one, 

 3-parted with close or subclose sinuses, glabrous on margin and on the 

 inner surface, but slightly pubescent at the throat, 7-11 mm. broad; mid- 

 lobe larger, lato-obcordate or very shortly produced at the apex, eroso- 

 crenulate above ; lateral ones oval, rounded at the apex ; tube exserted, 

 narrowed and glabrous below, densely pubescent with ascending hairs in a 

 broad ring at the infra-medium internally. Stamens shorter than the 

 posterior lip of the corolla, erect, very slightly longer in the anterior pair, 

 inserted at the throat, approximate ; filament linear-filiform, softly pubescent; 

 anther oblong-linear, cells much divaricate even refiexed, glabrous. Disk very 

 short, subequal. Style equal to the stamens in height, filiform, glabrous, 

 subunequally bifid into subulato-linear stigmatic branches, about 10-13 mm. 

 long. Ovary-lobes oval-ellipsoid, rounded-obtuse and subglandular at the 

 top, about 3 mm. long. Nutlet (immature) oblong, attenuated below, 

 truncate with angulate margin at the top, compressed-triquetrous, glabrous, 

 smooth, with a short disk (gynophore), about 2 mm. long ; disk slightly 

 thicker towards the anterior.
