pedicels erect-patent, strict, glabrous and light green as well as the common 

 peduncle, provided with a small and commonly linear or setaceous bract at 

 the upper part. Flowers small, dense, approximate, rather numerous, 

 9-10 mm in diameter. Calyx persistent ; tube obconical, 2 mm long, slightly 

 10-costate, viridescent, firmly herbaceous, rather thick, glabrous, smooth 

 internally ; lobes 5, spreading, but nearly erect in fruit, thick, deltoid-ovate, 

 acutish, entire, shorter than the tube, deeper green than the tube, with the 

 superficially scarcely • visible midrib, slightly fulvo-tomentose on the upper 

 surface. Corolla 5-petaled, patent, pale-white, contorted in aestivation, 

 deciduous; petal obovato- orbicular, clawless, retuse, slightly crispate on the 

 margin. Stamens 20, at first incurved, thrusting their anthers within the 

 calyx-cup over the annular disk, and then patent, shorter than the petal ; 

 filament subulate-filiform, white, glabrous ; anther minute, oval, dorsifixed, 

 yellowish-white. Disk annular at the throat of the calyx-tube, 10-crenato- 

 squamate, carnose, viridescent. Ovaries 5, entirely inclosed within the 

 calyx-tube, minute, erect, oblong, light green, very slightly woolly ; style 

 erect, longer than the ovary, exserted beyond the calyx-throat, filiform, 

 glabrous, with a slightly enlarged stigma. Follicles 5, erect, close-placed 

 one another, exserted, surrounding with the persistent calyx at the nearly 

 lower half, 4 mm long, sessile, crustaceous, slightly woolly, brown, narrowly 

 subfnsiform, subtriangnlar, narrowed downwards, rounded at the apex, with 

 very minute subterminal persistent style turned outwards ; seeds few, linear- 

 fusiform, straight, exalbuminoos, about 2J-3 mm long with brown smooth

Spircra tosaensis Yatabe in Bot. Mag., Tokyo, VI. p. 6. 



Norn. Jap. Tosa- shimot suite. 



Hab. Prov. Tosa : Matsubara in Takaoka-gori (T. Mahioio ! Nov. 8, 

 1885), Bank of Kiver Watari-gawa in Hata-gori (K. Waianabe ! Oct. 15, 

 1891, herb. Be. Coll. Imp. Univ. Tokyo). 



This is a marked southern variety of Spiraea bracleata Zabel (~S. 

 nipponica Maxim.), having very much narrower leaves than the type, and 

 is not yet found elsewhere besides the province of Tosa.
