Rynchospora (Dichostyleae) Umemurse Makino, sp. nov. 



(PI. VII. fig. 8, a. h.) 



CaiSpitose, attaining about 50 cm. in height, estoloniferous ; rhizome 

 very short, v^^ith fibrous roots. Culm erect, very slender, setaceous, one- 

 sulcate on one side, scabrous above, laxly short-branched, very laxly corymbi- 

 ferous throughout. Leaves setaceo-linear, 1 mm. or little more wide, much 

 shorter than the culm, trigonous and scabrous towards the obtuse apex. 

 Corymbs fasciculately 2-4-spiculose ; bracts setaceous, scabrous. Spicula3 

 erect, 2-3- sometimes 1-flowered, elUptico-ovate, shortly acuminate, ferrugineo- 

 brunneus, 3-3i mm. long. Empty glumes 2, ovato-lanceolate, very thin ; 

 flowering ones ovate. Setee 6, slightly longer than the achene, fulvous, 

 antrorsely scabrous. Stamen 1 ; filament lower than the rostrum of the 

 mature achene. Achene oval-obovate, biconvex, pale-flavescent with a 

 slight ferruginous stain, transversely sub-rugulose, IJ mm. long ; rostrum 

 angustato-conical, shorter than the achene ; style deeply bifid, branches § 

 as long as the main portion. 



Hah. Prov. Ise : Heki-mura (Z. Umeynicra ! Oct. 6, 1895). 



Very closely allied to Rynchospora Hattoriana Makino, but setas are 

 scabrous upwards, and spicuke are somewhat shorter ; probably it is a variety 

 of that species.
