Scleria pubigera Makino, sp. now 



(Subgen. Eu-Scleria, Sect. Tessellatse.) 



Annual, 2—4 decim. high, pubescent with retrorso-patent (but 

 ascending-patent towards the apex) short pale hairs ; roots 

 fibrous, tufted, finely filiform, with fine short rootlets, purple. 

 Stems densely casspitose, erect, leafy throughout, slender, trique- 

 trous with entire and ciliated edges, ^—1^ mm. across ; inter- 

 nodes long except the base. Leaves distantly alternate, linear, 

 acute or acuminato-acute, entire (not scabrous) and ciliated on 

 margin, membranaceous, not firm, attaining about 16 cm. long 

 in the largest ones, 2-4 mm. broad ; midrib slenderly carinate 

 dorsally ; veins 2 on each side, one median and one intra- 

 marginal (closely near the margin); veinlets 1—2 between the 

 veins ; sheath triquetrous with ciliated and entire edges, gradu- 

 ally compressed and enlarged above, attaining about 3 cm. 

 long, but shorter in the superior and inferior leaves, subnumer- 

 ous-nervate ; mouth semiorbicular, entire and ciliated on 

 margin. Panicles small, 1—2^ cm. long, erect, erect-patent or 

 spreading, terminal aud axillary, appear through the stem on 

 nodes except the very base, loosely straggling, peduncled and 

 often long so ; rachis flexuous, triangular ; bracts linear-subulate, 

 erect-patent, longer than the spikelets, membranaceo-dilated and 

 amplexicaul at the base, the lowest one largest and often leafy ; 

 peduncles 1-3 to a node, uuequal in length, slender, compressed 

 and narrowly ancipito alate, canaliculate in front. Fascicles
