Ithamnus nipponica Makino iiied. 



A shrub or small tree, spinose ; trunk unarmed ; branches atropurpureo- 

 griseous ; branchlets erect-patent, or subhorizon tally patent, subopposite, 

 glabrous, griseous or luteo-griseous ; bud-scales imbricated, coriaceous, ciliated. 

 Leaves alternate or 8ubo[)posite, petiolate, lanceolate-oblong, oblanceolato- 

 oblong, lato-lanceolate, but obovato-oblong, or obovato-elliptical, or elliptical 

 in those of the lower portion of branchlets, shortly acuminate or abruptly 

 short-acuminate or abruptly cuspidate, acute or obtuse and often oblique 

 at base, crenulato-serrulate with narrowly marginate teeth having a minutely 

 mucronate point in front, coriaceo-chartaceous, nearly concolorous, often 

 purprascent beneath in old ones, glabrous but slightly pubescent in the 

 axil of veins beneath, 3-lGcm. long, 2-.3 cm. broad; midrib straight 

 or scarcely liexuous, impress^ed above, prominent beneath ; veins 4-7 on 

 each side, loose, ascending ; veinlets finely and conspicuously reticulated 

 beneath ; i)etiole glabrous, 10-25 mm. long ; stipule setaceous or subulato- 

 setaceous, shorter tlian the petiole, caducous, 4-7 mm. long. Flowers 

 dia'cious, [)laced in the leaf-axil in the [)ortion of branchlets of this year, 

 yellowish -viridescent, glabrous. Male tiowers 1-18-fasciculate, dense, 



longer than the petiole of leaves of that place ; pedicel gracile, glabrous, 

 slightly shorter or longer than ilowers. Calyx 5 mm. long; tube obconical, 

 acute at base, disk very thin ; lolies 4, erect-patent or spreading, \\-2- 

 times as long as the tube, ovato-lanceolate or deltoid-lanceolate, subcalloso- 

 acutish at apes, trinerved and usually without veinlets, lateral veins dis- 

 appear before reaching the apex. Petals 4, shorter than calyx-lobes, oUong 

 or obovato-elliptical, shortly attenuated at base, obtuse, 1-nerved with a few 

 loose veinlets, scarcely longer than one-half of the calyx-lobe, thinly mem- 

 branaceous. iStauiens 4, shorter than the calyx-lobe, but scarcely longer than 

 the petal, erect ; Hlanieiit subulate ; anther shorter than filament, oblong. 

 lludimentary pistil minute and short, with the depressed-globose ovary and 

 the bifid style. Female fiowers 1-3-fasciculate, usually shorter than the 

 petiole of leaves of that place ; pedicel gracile, glabrous, 4-8 mm. long. 

 Calyx 4 mm. long ; tube short, obconico-semisphterical, disk thin ; lobes 4, 

 spreading or erect-patent, nearly thrice as long as the tube, oblong-lanceo- 

 late, ovato-lanceolote, or subulato-lanceolate, attenuated above- with an
