Ab A. annulato (seu A. Ischccmo, Roxb.) cui proxime accedit, differt : foliis angustioribus pilosis, nodis 

 culmi non pilis patentibus reflexisve sed mollioribus brevibus adpressisque cinctis, spicis brevioribus longius 

 pedunculatis, spiculis minoribus, H-lf lineas longis, quae a Hi 2|- lin. longse, gluma inferiori 6-nec 8-nervi, basi 

 margineque pilis brevioribus vestita. Reliqua omnino ut in A. annulato. Ab A. obtnso, N. ab E. (qui A. 

 JBladhii, Roxb.) longius distat glumis nee multinerviis nec apice, ut in illo, obtusatis, turn vero et spicis in 

 rhachi brevi approximatis, racemum abbreviatum fasciculi formem basi ssepe vagina involutum exhibentibus 

 nec longiori tractu in culmi parte superiori dispositis. 



3. A. (Trachypogon) Vachellii ; spicis verticillatis pedunculatis, pedunculis 1-2-sta- 

 chyis, axillis barbatis, rhachi pedicellisque ciliolatis ad genicula longius barbatis, spiculis 

 lanceolatis, gluma inferiori apice 6-8-nervia imperforata basi hirta, valvula inferiori flosculi 

 fertilis e basi lineari setigera, seta spicula multo longiori, [culmo infra nodos adpresse 

 barbatos hinc canaliculato,] folio supremo convoluto-setaceo brevi scabro, ore vaginae 

 barbato. N. ab E. in Herb. Lindl. [_(3, perfectior ; paniculae ramis subverticillatis patulis 

 flexuosis, inferioribus ramosis ramulis 1-2-stachyis, superioribus alternatim 8-2-stachyis.

 pollices longis, geminarum altera breviore : [in /3, inflorescentia paniculata conico-oblonga ; ramis ut supra 

 descriptis, inferioribus li-2\ pollices longis ; spicis 8-16 lineas longis, quandoque apice abortivis vel cito cassis
