Through Northern India to Tonkin and South-west China. The specimens 
enumerated here from the Cape Verd Islands and from the Futa Jallon are 
destitute of pedicelled spikelets, the pedicels themselves being reduced to almost 
microscopic points, very much as in the case of Arthraxon quartinianus, but the 
general appearance and the structure of the spikelets are entirely those of typical 
A. lancifolius. 
4. A. quartinianus, Nash in North American FI. xvii. 99 (18 Sept. 
1912). Annual. Culms very slender, ascending from a branched, 
sometimes prostrate and rooting base, from 3 in. to over 1 ft. high, 
smooth, glabrous or finely puberulous below the inflorescence, with 
solitary or 2- to 3-nate branches above, internodes mostly exserted. 
Leaf -sheaths lax, the upper often more or less inflated and bladeless, 
more or less hirsute in the upper part with tubercle-based hairs and 
densely ciliate along the upper margins, nodes shortly bearded; 
ligules membranous, ciliolate, short, truncate ; blades ovate-lanceolate 
to oblong-lanceolate from a cordate amplexicaul base, finely acumi- 
nate, 1 to over 1J in. long, 3-6 lin. wide, flaccid, with scattered 
tubercle-based hairs on both sides, ciliate towards the base, primary 
lateral nerves 3-4 on each side, very fine. Racemes 1 to about 9, 
in fascicles, borne on filiform, ultimately long-exserted peduncles,
