I have tentatively referred to this form; Kornicke says that this form 
is unknown to him, but that it has been experimentally cultivated in 
Germany and France. 
Setaria italica (L.) Beauv. subsp. rubrofructa Hubb. var. 
purpureoseta var. nov.

Panicle dense, often somewhat lobulate and interrupted at the 
base, but empty; 8 to 13 cm. long, 10 to 15 mm. in diameter. Leaves 
usually narrower and plant probably more slender and not as tall 
[specimens examined run from 5 to 8.5 dm. tall]. Setae purple or 
sometimes only purple-tipped, noticeably longer than the spikelets, 
but rather short, up to about 7 mm. 
Range. — The only specimens of this form which I have seen are 
cultural.
