 glabrous; inflorescence 5-7.5 cm long, with 5 to 6 racemes, densely hairy in the 

 axils of the raceme; axis of the raceme sinuous and sharply angled; spikelets 

 solitary, 3-3.6 mm long (average length of ten spikelets 3.3 mm); second glume

 Panipum supernum Swallen, sp. nov. 



Perenne; culmi dense caespitosi, graciles, erecti, ramosi ramis appressis; 

 vaginae internodiis multo longiores, glabrae; ligula brevissima, erosa; laminae 

 2-4 cm longae, involutae, erectae vel curvatae, subtus glabrae, supra pilosae, 

 marginibus ciliatae; paniculae fragiles 2-6 cm longae, ramis filiformibus adscen- 

 dentibus paucifloris; spiculae longipedicellatae, 1.4 mm longae, ellipticae, 

 glabrae; gluma prima angiista, acuta vel subobtusa spicula 1/2 brevior; gluma

Perennial; culms slender, densely tufted, strictly erect, branching from the 

 middle and upper nodes, the branches closely appressed: sheaths much longer 

 than the internodes, glabrous; ligule a very short, thin, erose membrane; blades 

 mostly 2-4 cm long, involute, blunt, straight or curved, glabrous on the outer 

 surface, pilose on the inner surface, ciliate, the hairs mostly enclosed; panicles 

 fragile, exserted on very slender peduncles, 2-6 cm long, the filiform branches
