Panicum. triaxdria digynia. 311 



vated sorts last described, bowing from the weight of the 

 grain, it is composed of alternate, compound, nearly secund 

 racemes. Rachis; common from four to five-sided; partial 

 three-sided, winding, and hairy. Calyx, glumes many nerv- 

 ed, otherwise smooth. Carol; the neuter valve is here pre- 

 sent, and in luxuriant plants, the stamens also. Seed oval, 

 transversely wrinkled, which distinguishes it from all the 

 other panicled species. 



4f>. P. plicatum. R. 



Erect, herbaceous, harsh with stiff hairs. Leaves lanceo- 

 late, plicate. Panicle lanceolate, ramifications compound, 

 flowers paired, polygamous. 



Introduced into the Botanic garden, from the Island of 

 Sumatra. Flowering time the beginning of the cold season. 



Root perennial. Culms erect, or ascending*, below as thick 

 as a goose-quill, and then somewhat compressed ; every part 

 filled with pith. Leaves sub-bifarious, expanding, lanceolate, 

 plicate, a little hairy ; from six to twelve inches lono-, and 

 from one to two broad. Sheaths about the length of the joints 

 of the culms, armed with sharp, rigid hairs; mouth ciliate. 

 Panicle oblong, lax ; lower ramifications rather remote, above 

 approximate, and composed of unilateral short spikelets. 

 Flowers solitary, paired, or threefold, when more than one 

 they are on pedicels of unequal lengths ; sometimes there is a 

 single coloured bristle from the pedicels of the exterior flow- 

 ers. Calyx three- valved, two-flowered, one of the flowers 

 mule. Avith a corol of one membranaceous glume; the other 

 hermaphrodite, and having the usual two-valved corol. Seed 

 oblong, rugose on the convex side. 



Obs. It is of too coarse a nature for cattle, but its foliage 

 make it ornamental in the shrubbery, or flower-border. 



50. P. nervosum. R. 



Erect, from three to four feet high. Leaves lanceolate, plait- 

 ed. Sheaths longer than the joints, with the mouths bearded.
