very scarcely shorter than the tube. Corolla pubescent exter- 

 nally but villose in the under side of the lower lip; tube exserted, 

 slender, hardly arcuate, somewhat obliquely swollen at the base, 

 naked but only pilose-annular near the base internally ; upper 

 lip much shorter and smaller, deeply bifid with deltoid lobes ; 

 lower lip 5—7 mm. long, dilated, 3-lobed ; lateral lobes 

 oblong-lanceolate acute or shortly acuminate ; midlobe larger 

 and slightly longer, broadly cuneate, emarginate with a 

 projecting tip in the bottom of the sinus, about 3|— 4 mm. 

 broad. Stamens didynamous, more or less exserted, nearly 

 equal to or somewhat longer than the upper lip ; filaments 

 very thinly pilose or subglabrous ; anther deltoid-subreniform. 

 Style slightly exceeding the stamens, bifid at the end, the lower 

 slightly shorter. Ovary-lobes ellipsoid. Nutlets ellipsoid, 

 rounded-obtuse at the top, reticulato-rugose, glabrous, about 

 2 mm. long. Flowers in April-May.

Common in the vicinity of Tokyo. It differs from Ajuga 

 genevensis Linn, in which the leaves are more deeply sinuate or 

 dentate, texture thicker, veins more conspicuous, petiole much 

 shorter, bracts more deeply cut, flowers deeper coloured, lateral 

 lobes of the lower lip obtuse, and stamens more exserted. In 

 the present species the radical leaves are usually lacking 



Maximowicz's Ajuga genevensis var. pallescens seems to be 

 principally based on A. reptans var. japonica Makino, and 

 probably partly on the present species. 



There is a hybrid between this Ajuga nipponensis Makino, 

 and A. decumhens Thunb., having the ascending or subdecum- 

 bent stems, cinuato-dentate leaves, axillary verticillasters to- 

 wards the top of the stem, and violaceous flowers. = Ajuga 

 mixta Makino, nom. no v.
