 NANo : Mt. Togakushi (K. Wotanahe ! Aug. 20, 1893) ; Prov. Ugo : Kotaki

Robuster than the type, attaining 55cm. in height. Stem attaining 

 2mm. in diameter. Corymb compound, attaining 2Jcm. across ; radii about 

 2-5, unequal, peduncled, the peduncle attaining SJcm. in the longest one.

Ilab. Hyljga: Tsuno (K. Saida and H, Sahurail herh. Imp. Househ.

Raceme 26cm. long in my specimen. 



Icon. linuma^s Somoku-Dzusetsu XVII. fol. 30 recto, n. 26. 



Hah. Prov. Mutsu: Same, near sea (Y. Yamasahil no. 23, August 1903). 



This is occasionally found growing wild in the middle (after Y. linuma) 

 and northern Japan. The Yamasaki's recent collection surely proves that 

 besides Mandshuria this species is also found in Japan. It is probably 

 erroneous that man says that it grows in Loochoo. 



Polygonum (Bistorta) hayachinense Makino, sp. nov. 



Quite glabrous, attaining about 25cm. in height. Rhizome thick, 

 igneous, tortuous, repent, nigro-castaneous ; roots nigrescent. Stem erect, 

 annual, narrow, simple, monostachyus, remotely 2-4-leaved. Leaves char- 

 taceous, subcrispate and narrowly revolute margined, subglaucous beneath, the 

 both surfaces venoso-reticulated with veinlets ; radical ones long-petiolate, 

 oblong-lanceolate, ovate-lanceolate, oblong, or ovate, obtuse, subtruncato- 

 ronnded or subcordato- truncate at the base, with many and erect-patent 

 lateral veins, 6-8cm. long, 2J-3cm broad ; petiole slender, apterous, with 

 a long membranaceous sheath, attaining 8cm. long ; cauline leaves much 

 smaller, shortly but distinctly petiolate, ovate to linear-lanceolate, obtuse, 

 rounded-obtuse at the base, but the superior ones acute at the base, the 

 uppermost one sometimes reduced into a setaceous shape, the sheath long.
