This differs little from S. multispiculata but in the denser panicle. Buchanan’s 
example is imperfect, and may not be S. po@oides, but it must be of this small 
group as the ripe nuts show. 
23. S. lithosperma, Swartz, Prod. 18. Nearly glabrous, except 
the leaf-sheaths. Rhizome horizontal. Stems 14-3 ft. long, medium- 
sized or slender, not tufted. Leaves 6-12 by 4-1 in. Panicle strag- 
gling; the remote axillary peduncles carrying a few-flowered irregular 
corymb or often only a spike of 1-5 separate spikelets; lowest bract 
altogether similar to the highest leaf. Spikelets in small clusters OF 
solitary, 4 in. long, pale brown marked with green, many moncecious.
