This is best distinguished from Scirpus fuirenoides Maxim, by the com- 

 pound cyme, narrower glume, mure delicate sette, smaller caryopsis, robuster 

 stem, and the broader leaves. It is not uncommon in the environs of Tokyo. 



I have proposed to dedicate this elegant species to Prof. Dr. Kakichi 

 Mitsukuri, Director of the Science College, Imperial University of Tokyo. 



Scirpus (SilvaticEe) fuirenoides Maxim, in Mel. Biol. XII. p. 555, 



(1886). 



Rhizome very short, oblique, thick, rooting below. Stem erect, strict, 

 slender, attaining about Im. in height, subtrigonous-terete, shining, foliate. 

 Leaves elongate, angusta to-linear, long-acuminate, shorter than the stem 

 but the superior ones exceeding it, glabrous, scabrous-margined, subcoria- 

 ceous, 3-7 mm. broad ; midrib very delicately carinate beneath, scabrous 

 on the carina above ; veins very closely placed ; sheath tubular, truncate 

 at the mouth ; the radical leaves casspitose, dilated and embracing at the 

 base. Cyme terminal (2^-6 cm. long), or lateral (the lateral ones often 

 1-headed and sometimes long-stalked), simply corymboso-umbellate ; pedicels 

 1-5, strict, erect or erect-patent, compressed, unequal in length, the longest 

 one about 4| cm ; involucral bracts 1-5, unequal in length, angustato- 

 linear, long-acuminate, dilated and clasping at the base, scabrous on the 

 margins and on the midrib beneath, the external longest one exceeding the 

 umbel. Spicule numerous, sessile, glomerate into a semi-globose or globular 

 head l-l|cm. across, oblong or oblong-cylindrical, obtuse, about 6-9 mm. 

 long, darkish viridescent and then darkish fulvous, with ferruginous styles, 

 the central (interior) head sessile ; rachilla glabrous, thickish ; bracteoles 

 subulato-lanceolate, attenuatedly acuminate, hyalino-margined, usually shorter 

 than the head. Glumes densely imbricated, lato-lanceolate, or ovate, 

 subnavicular, acute at the apex with a spinulose tip, 2^-3mm. long, 

 subhyalino-membranaceous, scabro-serrulate on margine, colourless and then 

 more or less light ferruginous, but darkish viridescent and then brunneo- 

 ferruginous along the midrib. Set;\i 6, hlifrom, glabrous and white, but 

 scabro-spinulose and slightly enlarged and more or less orange-coloured
