SETARIA ITALICA AND ITS IMMEDIATE ALLIES 
Prof. Hitchcock in the Manual describes the variety as follows, 
"Golden-Wonder Millet, which is more slender and has bristles 
shorter than the spikelets." This description would apply to several 
of the variations mentioned in this paper. The common name 
Golden Wonder Millet applies to forma breviseta, a very large, lobulate- 
panicled form. 
Key to species treated, 
a. Setae retrorsely barbed. 5. verticillata 
a. Setae antrorsely barbed, b. 
b. Spikelet articulate below the glumes; complete spike- 
let shells out leaving a cup-like receptacle. 5. viridis and varieties 
b. Spikelet articulate above the glumes; fruit only shells 
out leaving the glumes and sterile lemma behind. 5. italica and variations- 
Setaria verticillata (L.) Beauv. Agrost. 51, 171, 178 (181 2). I 
have not attempted to go into the involved synonymy of this species 
as it is readily distinguished from S. viridis var. ambigua, — which it 
otherwise resembles, — by the retrorsely barbed setae. From the 
material I have seen I am inclined to agree with Sir. J. D. Hooker, 
FI. Brit. Ind. 7: 80 (1896) in considering S. Rottleri Spreng. synonym- 
ous. 
Range. — Sparingly introduced in Canada, in the United States, 
mainly eastwards, in Mexico and Central America. In Venezuela? 
and Brazil fide Doell. Common in Europe, occurring in several 
sections of Africa, in Asia Minor, British India, Philippines, Australia 
and Hawaii.
