 midrib beneath, the outer ones longer than the panicle, attaining about

This grows in the boggy i)lace in Karuisawa plain. It differs from 

 Scirpus fuirenoides Maxiu]. (Photogr. 3.) by the much denser panicle ; 

 smaller and more numerous heads ; not darkish viridescent spicuhe ; and 

 smaller ferruginous glumes; from S. Mitsiihuriamislsliikmo (Photogr. 2.) by 

 the smaller habit ; smaller and narrower leaves ; smaller stem ; smaller 

 and denser panicle ; erect radii ; smaller and more numerous heads ; more 

 loosely notched rachilla ; shorter and broader glumes ; shorter and stouter 

 setre ; and larger caryopsis ; and from S. cyperimis Kunth and its varr. 

 Erloplioi'uv}, concolor, and JFichurai by the smaller habit; less compound 

 and not effuse panicle ; larger and not solitary or not few-aggregate spicule ; 

 much larger glumes ; and larger caryopsis.
