A Classification of the Varieties of Cultivated Oats 151 
Early Gothland (Plate XVIII, 3, and fig. 26). — Culms, sheaths, leaves, 
panicles, and glumes similar to those of Early Dakota, except that the 
glumes are somewhat longer; spikelets 2-3-grained; grains white to yellow- 
ish white, elongate, outer grains 18-22 mm. long, long-pointed; lemma of 
the outer grain glabrous, with 7 obscure nerves; awns numerous in the 
panicle, usually not twisted; basal hairs extremely short (1-2 mm.), nu- 
merous; rhachilla of the outer grain 2-3 mm. long, usually haired. Plants 
9-11 dm. tall; late in maturing. 
Specimens of the variety Early Gothland were found under the following 
additional names: Banner, Danish, Schoenen. 
Belyak (Plate XVIII, 4, and fig. 25). — Culms erect in early growth, me- 
dium large, stiff, hairy near the nodes; sheaths dark green and glaucous at 
period of full heading; leaves colored as the sheaths, medium wide, margins 
glabrous; panicles medium long, rather broad, somewhat compact, stiff, 
erect, the branches ascending; spikelets 2-3-grained; glumes dark green 
and somewhat glaucous at period of full heading, 20-25 mm. long, usually 
9-nerved, sometimes 10-nerved; grains white to yellowish white, plump, 
outer grains 16-19 mm. long, short-pointed, the dorsal side concave in the 
region of the awn; lemma of the outer grain glabrous, with 7 obscure 
nerves; awns wanting or few in the panicle, seldom twisted; basal hairs 
wanting or extremely short; rhachilla of the outer grain short (1.5-2.5 
mm.), usually glabrous. Plants 9-11 dm. tall; medium late in maturing. 
Another specimen of the variety Belyak was found under the name 
White Belyak. 
Silvermine (Plate XIX, 1, and fig, 29). — Culms, sheaths, leaves, panicles, 
and glumes similar to those of Belyak, except that the panicles are more 
elongate and their branches ascend more sharply; spikelets 2-3-grained, 
2-grained spikelets largely predominating; grains white to yellowish white, 
plump, outer grains 16-19 mm. long, short-pointed, the dorsal side scarcely 
concave in the region of the awn; lemma of the outer grain glabrous, 
with 7 obscure nerves; awns wanting or few in the panicle, usually not 
twisted; basal hairs usually wanting; rhachilla of the outer grain 2-3 mm. 
long, usually with a few weak, short hairs. Plants 9-11 dm. tall; medium 
late in maturing. 
Specimens of the variety Silvermine were found under the following 
additional names: American Banner, Big Four. Big Four (Salzer's), 
Boehmerwald Mountain, Bussey, Canadian, Curel 6, Danish Island,
