Rumex (Lapathum) Andreaeanus Makino sp. nov. 



A perennial, about 12 decim. high, slightly branched; rhizome thick, 

 intensely yellow, with fibrous rootlets. Stem erect, slender, somewhat 

 flexuous, loosely foliate, passing into a rachis of the inflorescence above, 

 subglabrous, viridescent. Kadical leaves long-petiolate, oval to ovato-oval, 

 rounded rounded-obtuse retuse or emarginate at the apex, cordate at the 

 base with rounded lobes, more or less crispate and slightly irregularly un- 

 dulate, glabrous above, pubescent on the midrib lateral veins and principal 

 veinlets beneath, membranaceous, flaccid-herb icpous, 22-25 cm. long, 15- 

 1CJ cm. wide ; veins spreading, many ; petiole longer than the blade, 

 slightly pubescent above, about 30-38 cm. long ; basal sheath thinly mem- 

 branaceous ; cauline leaves smaller, shortly petiolate, ovato-oval, attaining 

 about 15 cm. long, lljcm. broad, with thinly membranaceous sheath 

 shorter than the petiole, the superior leaves gradually smaller (narrowly 

 ovate) upon it and at length passing into oblong-lanceolate shortly pstkilate 

 and loosely placed bracts (the smallest one about 4 cm. long and 1cm. 

 wide). Panicle narrow, pauci-ramose below, about 4decim. long; common 

 rachis erect, slender, straight but subflexuous below, sparsely short-pubescent, 

 naked from bracts above, the flowering branches erect-patent or ascending, 

 simple, ebracteate ; bracteoles very minute, membranaceous. Whorls loose, 

 the inferior ones remote and numerously crowded-flowered but loosely few 

 to several flowered above. Flower small, about 2j mm. long, viridescent, 

 glabrous. Sepals ovato-oblong or elliptical-oblong, obtuse, concave, entire,
