var. glabra Makino var. nov. 



A shrub, densely ramose; branches fulvo-isabel-coloured, slightly flexnous, 

 terete. Leaves alternate, shortly petiolate, elliptical or obovato-elliptical, 

 shortly acnte-acuminate, usually acute at base, serrate with mucronato- 

 acute teeth, chartaceo-membranaceous, nearly concolorous, but sometimes 

 subglaucous beneath, glabrous but slightly puberulent in axils of veins 

 and along the midrib or sometimes ciliated on margin, 2-6 cm. long, 

 lJ-3cm. broad; midrib and veins prominent beneath and the latter 4-5 

 on each side, with numerously reticulated inconspicuous veinlets ; petiole 

 glabrous, 3-7 mm. long. Cymes compound forming a small ovato-oblong 

 panicle (about 5-11 cm. long), terminating a short glabrous lateral branchlets 

 (of this year) which are foliiferous below, glabrous ; rachis gracile, flexuous, 

 branches loosely disposed, short, erect-patent or patent, about 2-9-fiowered. 

 Flowers white, about 7mm. across, jointed with the pedicel ; pedicel short, 

 gracile. Calyx-lobes 5, patent, small, ovato-elliptical, or deltoid-ovate, obtuse, 

 glabrous but ciliolate. thikish, slightly concave, few-nerved, about 1mm. 

 long. Petals 5, patent, ovato-elliptical, rounded at apex, entire, often 

 ciliolate above, 5-7-nerved, 3-3^ mm. long, 2-21 mm. wide. Stamens 

 numerous, sub-5-delphous, equal to petals in length, glabrous ; filaments 

 filiform, tapering at apex ; anther ovoid to lato-ovoid, minute. Style 1, 

 erect, scarcely lower than stamens, filiform, glabrous ; stigma subbilohed ; 

 ovary small, obconical, glabrous. Fruit shortly ovoid, scarcely oblique, 

 black (not blue) when matured, 5— 7 mm. long. Flowers in May.

 Uyeno (G. Nagura !), Takashi-mnra (T. Makino ! Oct. 25, 1893, Oct. 29,

This is found in Middle Japan. Miquel's Symplocos paniculata t 3. 

 parvifolia probably belongs to this. 



Arabis (Euarabis) iwatensis Makino sp. nov. 



Perennial, laxly csespitose, attaining about 5 cm. high in flower, but 

 about 8 cm. high in fruit. Leaves thickish, disparsed and ciliated with 

 rigid bi-furcate erect hairs mixed with simple ones, the under surface very 

 thinly disparsed with simple and bi-furcate minute hairs, green, concolorous; 

 rosulate leaves patent, petioled, orbiculate or lato-orbiculate, rounded at 

 the apex, suddenly reduced and slightly decurrent to the petiole at the
