139. GRAMINE.E. [65. Arthraxon. 



ceous, i oblong, broadly truncate, irregulai'ly 3-4-tootlied, 7-8-nerved, 

 dorsally convex ; ii longest, lanceolate, narrowed into a straight awn, 

 3-7 -nerved hispidly hairy on the sides and with dorsal tufts of hairs 

 below the middle ; iii hyaline, oblong-lanceolate, acute or aristulate, 

 ciliolate, 1 -nerved, 1-2-androus or neuter, palea linear 2-nerved ; iv 

 nearly as long as iii, fern, or 2-sexual and 2-androus, linear-oblong, 2-fid, 

 lobes setiforni and margins hispidulous, awn in the cleft much longer 

 than the glume tortuous ; palea quadrate, lobulate, 2-nerved. Lodi- 

 cules 0. Anthers narrow. Style connate below, stigmas very long. 



I. L. Kingii, Hook. f. 



Densely tufted with many fastigiately branched stems 9"-l ft. 

 high, sometimes subcorymbose above. Leaves narrowly linear, 

 radical 8-9", gradually smaller upwards and sheathing the peduncles, 

 lower -05" broad, nodes, base of leaves and mouth of sheaths softly 

 villous. Peduncles very slender, the branched spike breaking off shortly 

 above the mouth of the sheath, -S--?" long (without the long awns), 

 base of joints and callus all with a barb of brown hairs, obtuse. Spike - 

 lets sessile and pedicelled or sometimes a pair of sessile and pedicelled 

 together. Sessile spkt. •25--3" long (without the awns), gl. i •16--18" 

 oblong, 8-nerved below the membranous truncate tip which is 

 2-cuspidate and obtusely 3-toothed between the cusps ; ii 3-nerved 

 keeled, -25" or more, sides villous except at base and a dorsal tuft of 

 hairs above base on each nerve, awn slender ; iii oblong-lanceolate 

 or linear, if linear then 2 -toothed with a short central awn half as 

 long as glume, if oblong-lanceolate then entire, acute aristulate and 

 ciliate ; iv -2" long with 2 long acuminate scabrid lobes and a central 

 long awn -6" long, palea often -1" long, very broad. 



Monghyr, Mokim ! Fl. Oct. 



Basal spikelefcs all male in some specimens. Pedicelled spkt. very similar to the 

 sessile but gl. ii 5-7-nerved with the tufts of hair forming a continuous transverse 

 band, awn about as long as spkt. (as in the sessile). The peculiarity of the 

 dimorphous gl. iii appears to occur in both sessile or pedicelled spikelets ! Pedicel 

 •08" long, bearded. 



66. ARTHRAXON, Beaiiv. 



Slender grasses with many short lanceolate to ovate deeply cordate 

 leaves and digitate or fascicled or shortly racemed simple or branched 

 spikes. Spikelets solitary, or binate with the pedicelled spikelet 

 reduced, male or neuter or the pedicel only represented. Glumes 4 ; 

 i not or scarcely embracing the inner ; ii subequal or shorter, keeled, 

 3-nei'ved, conduplicate embracing the inner ; iii smaller hyaline 

 nerveless ; iv as long as iii or shortest, lanceolate, keeled, hyaline 

 with a long dorsal or sub-basal awn ; palea minute or 0. Lodicules 

 sub-quadrate. Stamens 2-3. Styles short or 0, stigmas long, 

 laterally exserted. Grain linear.
