190 JOWITT : NOTES ON DR. OTTO STAPF's 



the middle, which is J to | inch wide, to a narrow base, in 

 flowering stems decreasing in length upwards, but generally 

 with broader bases and larger auricles, coriaceous, surfaces 

 smooth, margins softly serrate, yellow -green above, in young 

 plants bright green, glaucous beneath, mid-rib depressed above, 

 well defined, paler than the rest of the blade, but not conspi- 

 cuously white, except occasionally in floral leaves, prominent 

 beneath — mid-rib dries white. 



Sheaths much shorter than the internodes, smooth, shiny, 

 many, and closely vemed, light yellowish green or tinged with 

 purplish red, auricle the thickened tinged base of the leaf, 

 ligule short, or somewhat ovate dorsally, ventral margins 

 produced into irregularly obtuse auricles, scarious, often 

 lacerate, cilia te. 



Panicle leafy, erect when young, afterwards drooping, 

 zigzag, elongate, interrupted, effuse, very many flowered, 

 villously ciliate. 



Spikes on the branches of a slender pedicel or on those of 

 fascicled unequal pedicels, springing from the nodes of the 

 stem, with chaffy bracts at their bases, stem channelled for 

 their reception, protected by the sheath of a leafy bract. 



Bracts and chaffy bracteoles at the base of all the pedicels, 

 upper portion of pedicel ciliate, bracts lanceolate, acuminate, 

 glabrous, coriaceous, many veined, margins of sheathing 

 petioles membraneous, of blades serrulate. 



Spikes binate, unequal, at first erect, afterwards deflexed, a 

 longer shortly pedicelled arm and a shorter sub-sessile one. 



Spikelets in pairs, a sessile bisexual and a pedicelled male, 

 3 to 4 on each arm, on both, the terminal pedicelled spikelets 

 are binate. The pair of homogamous spikelets at the base of 

 the sub-sessile arm are male. 



Internodes and pedicels of upper spikelets villously ciliate. 



Sessile Spikelet. — 5 to 6 mm. long, ovate oblong, acute, 

 callus bearded. Glume I., flat, softly coriaceous, acuminate, 

 often obliquely so, occasionally bifid, margins inflexed, 

 scaberulous, wings none or obscure, green or slightly coloured, 

 intermediate veins 3 to 5. II. as long as I., translucently 

 coriaceous, 1 veined, vein excurrent, merely a trace of a wing 

 on the keel, the upper portion of which is minutely toothed.
