Arundinaria Owatarii Makino sp. nov. 



Branches slender, numerously ramulose ; nodes not promi- 

 nent : internodes terete, fistulose, smooth, thickly walled ; sheaths 

 glabrous. Ultimate ramules gracile, with white waxy bloom 

 under nodes. Leaves 6— 13cm. long, 2— 1km. broad, 1—3 to 

 an ultimate ramnle and placed at the top of it, approximate, 

 angustato-lanceolate, strongly acuminate, acute and very shortly 

 petiolate at the base, spinuloso-ciliated on margins, glabrous on 

 both surfaces, green above, glaucous beneath, thinly chartaceous ; 

 midrib slender, prominent beneath ; mains veins 2-4 on each 

 side ; veinlets tessellate ; petiole 1—2 mm. long, very minutely 

 puberulous on the inner side ; ligule short, truncate, puberulous 

 dor-ally ; sheaths shorter than leaves, narrowly terete, slightly 

 striate, ciliated, often purpurascent above, those in the lower 

 portion of ramules provided with only a minute linear-subulate 

 microphyll, the lower ones usually shorter than the internodes. 

 flower unknown. 



Mom. Jap. Yakushima-dakc (nov.). 



Hab. Prow Osumi : [si. Yakushima (C. Owatarii herb. Sc. 

 Coll. Imp. Univ. Tokyo). 



In our single specimen the culm is lacking. Probably a 

 small and handsome bamboo. It seems to me to be allied to 

 Arundinaria japonica Sieb. et Xuec (Japanese Ya-dake), but is 

 much smaller in every aspect. 



Aster Kodzumanus Makino sp. nov.
