Undoubtedly a rare species in the middle part of Japan. In 1829, 

 figures of this plant and some brief remarks appeared in T. Iwasaki's 

 " Honzo-dzufu " vol. VII, and afterwards, in 1856, Y. Iinuma mentioned 

 it in his work "■ Somoku-dzusetsu " vol. VI. under the name of Sute-kobiru, 

 a name proposed by himself. My best thanks are due to Mr. Gr. Nagura 

 of the province of Mikawa, for his kind gift of dry as well as living 

 specimens which has collected by himself of this rare novelty. 



Lycopus angustus Makino, in Bot. Mag., Tokyo, XL 1897, p. 382. 



Rhizome repent, with fibrous roots. Stem erect, slender, 3-10 decim 

 high, simple or with loose slender and ascending branches, sending slender 

 epigseous stolons from the base, tetragonous, acute-angled in the superior 

 portion, glabrous, but pilose at the nodes. Leaves opposite, subcoriace- 

 ous, erect-patent or spreading, distant below but closer above, narrowly 

 lanceolate, acuminate with subcallose tip, but much narrower in the 

 superior ones, very shortly petioled, 2J-9 cm long, -J-2 cm broad, usually 

 more or less scabrous above and on the margin, glabrous and covered 

 with minute and numerous dots below, inferior ones inciso-dentate 

 with ascending subarcuate and subcallose-tipped teeth, abruptly rounded 

 or cordate, superior ones gradually decreasing in size, rather remotely 

 serrate with subcallose-tipped teeth, midrib prominent beneath, usually 

 glabrous ; veins loose, arcuate, ascending ; petiole 1-2 j mm long. Ver- 

 ticillaster small, axillary, sessile, dense and rather many-flowered. Bracts 

 lanceolate, usually a little exceeding the calyx in length, with a 

 spinescent-tapering tip, more or less scabrous-ciliated, with a prominent 

 midrib; bracteoles lanceolate-subulate, slightly ciliated, spinescent-acuminate, 

 shorter than the calyx. Flower minute, sessile. Calyx campanulate, 

 almost glabrous, sparsely glandular outside, 2 j-3 j mm long ; tube short, 

 broad, rather membranaceous ; lobes 5, rather rigid, erect-patent, with 

 obtuse sinuses between them, diltoid, narrowly spinescent-acuminate,- carinate 

 backwards on account of prominent rib, usually longer than the tube, 

 trinerved except the posterior one which is smaller in size, subscabrous 

 on the margin. Corolla slightly exserted, about 2J-4J mm long, white, 

 covered with very minute glands in the upper portion externally, hairy on 

 the anterior portion in the throat inside ; tube more enlarged above ; lobes 

 4, patent, much shorter than the tube, posterior one broadly semiorbicular 

 with rounded or emarginate apex, lateral ones smaller, suborbicular, anterior 

 one suborbicular with retuse apex or 4-lobed, slightly longer than the othesr. 

 Stamens inserted on the middle part of the corolla-tube, and alternate
