Plains of INDIA, from Kashmir to Bengal, and southward to CEYLON. DISTRIB. 

 Tropics generally. 



Annual. Stem 1-2 ft., decumbent and rooting below, nodes pubescent. Leaves 

 1-5 by f in., flat or undulate, very variable in breadth and form of base, lanceolate, 

 acuminate and loose sheath laxly hairy ; ligule a beard. Spikes f-2 in. long, secund, 

 spreading; rachis 3-gonous, pubescent and with a few long hairs. Spikelets i in., 

 geminate or upper solitary, usually pubescent, pale ; pedicels very short ; gl. I acute 

 or obtuse ; III male, palea oblong; IV rounded at the tip. Kuuth (Revis. Gram. i. 

 206) says, under Urochloa panidndes, that he has examined in Desfontaine's 

 Herbarium the type of Poiret's P. javanicum, and identified it, which he cites as a 

 syn. of Urochloa panicoides, but his figure of which again quite accords with a 

 narrow-leaved form of P. Helopns, Trin. This requires the adoption the name 

 javanicum (by misprint japonieum in Kunth Revis. ), for the species. Bentham, on 

 the other hand (Fl. Austral, vii. 477), says that Munro has seen an authentic speci- 

 men of javanicum, and that it is quite distinct from P. Helopus. I have no means 

 of verifying either authority.

Plains of INDIA, from Scind and the N.W. Provinces to Behar and southward to 

 Madras. DISTKIB. Affghan. 



Annual ? Stem 1-3 ft., decumbent and branched below ; branches erect, leafy. 

 Leaves 3-4 by ^-1 in., lanceolate, acunSinate, thin, glabrous or pubescent, base 

 ronnded and usually deeply lobed, margins minutely ciliolate ; sheath glabrous or 

 pubescent, mouth usually ciliate ; ligule short. Panicle 2-6 in., inclined, oblong, 

 glabrous or pubescent ; rachis angular. Spikes 1-2 in., erecto-patent, rather distant-, 

 sometimes divided at the base. Spikelets alternate, close or distant, often in paii-s 

 a sessile and pedicelled, pale green or yellowish, turgid ; pedicel usually with long 

 cilia. I think this is certainly P. umbrosum, Retz & Roxb. 



13. P. setigrerum, Retz. Obs. iv. 15 ; leaves ovate-lanceolate with long 

 cilia towards the amplexicaul base margins below crenulately wrinkled, 

 spikes alternate, pedicels with scattered long hairs, spikelets in. biseriate 

 alternate imbricate subsessile ovate acuminate glabrous or pubescent, gl. I
