Panicum. triandria digynia. 287 



numerous, covering- most completely every part of the ra- 

 cemes, pedicelled, oval. Calyx, two inner glumes striated. 

 Corol no neuter, only one hermaphrodite. Seed smooth, shin- 

 ing, white. 



Obs. This may be only a variety of P. interruptum. 



9. P. dimidiatam. Linn. sp. pi. ed. Willd. i. 339. 



Spikes secund, jointed ; joints excavated, daggered on al- 

 ternate sides of the apex, from one to five-flowered. Calyx 

 two-flowered, one hermaphrodite, the other male. 



A native of the Peninsula of India, scarce. 



Culms short, oblique, smooth ; whole height from six to 

 twelve inches. Leaves slender, smooth, obtuse, rather broad 

 toward the apex. Spikes solitary, secund, jointed, smooth, 

 from three to five inches long. Joints of the racltis from 

 eight to twelve, rigid, excavated for the reception of the flow- 

 er, except the lower one or two, which are longer ; in all ex- 

 cept these a long sharp point or dagger proceeds from the 

 apex, on the alternate sides of the articulation. Flowers lodg- 

 ed in the concave joints of the radii*, on very unequal pe- 

 dicels, the lowermost having each three or more, while those 

 about the middle of the spikes have uniformly two, and the 

 last two or three only one. Calyx two-flowered, two-valved ; 

 flowers both sessile, one hermaphrodite, the other male; 

 valves unequal, the exterior one smaller ; the inner one about 

 as long as the valve of the corol, or it may be described with 

 three valves as in the genus; but then the male flower will 

 have but one glume. Corols two-valved ; valves nearly equal, 

 those of the male flower much firmer, the sides of the exterior 

 one (which maybe called the inner valve of the calyx, if it 

 be allowed, to have three), with the sides bent in at right an- 

 gles. Stamina three. Germ in the hermaphrodite flower ob- 

 long. Style undivided for a short distance. Stigma plumose. 

 Seed oblong, dark brown, dotted ; on the anterior side near 

 the base is an oblong elevated mark.
