The examples of var. 8, being destroyed by smut, are doubtfully determined, 
and may belong to T. circinalis. The spikelets would do for those of 7. circinalis, 
but the tall stems 16-30 in. high are more like those of 7. flexuosa. 
/ 18. T. robusta (C. B. Clarke in Durand and Schinz, Conspect. Fl. 
Afr, v, 662); glabrous; stems 3 ft. long, stout, trigonous, nearly 
smooth, with a leaf-bearing node far above the base ; basal leaf-sheaths 
entire, firm; leaves 10-20 by 1-1 in., stout, flat; panicle 12-18 by

This plant is quite different from the preceding and naturally belongs to the 
next series, but the glumes are not aristate.

Fl. Afr. y, 663); glabrous; rhizome stout, horizontal, woody; stem 
stout, scabrous on the margins ; sheaths entire, firm; stem-leaves 
Similar but, smaller, from cylindric sheaths, passing into the similar 
tacts; panicle 12-24 by 1-2 in., of numerous axillary branches, 
somewhat nodding at the top; spikelets dusky-brown, clustered in 
the axils of secondary ovate-lanceolate bracts, } in. long, elliptic- 
lanceolate ; empty lower glumes about 6, 4 in. long, subdistichous, 
long acuminate, acute, puberulous ; lower flower male, with an im-

hor feathered) ; stamens 3 ; anthers of the genus with small sterile 
basal ears; style-base when young ovoid, broader than the young 
Pistil, scabrous, ultimately contracted into a small boss at the top ot 
the large nut ; nut (including the stalk) nearly 34 in. long, ovoid,
