A Classification of the Varieties of Cultivated Oats 157 
I few; rhachilla of the outer grain 2-3 mm. long, glabrous or occasionally with 
a few fine, short hairs. Plants 9-13 dm. tall; medium late in maturing. 
Black Tartarian (Plate XXI, l,and fig. 13). — Culms erect in early growth, 
( large, coarse, glabrous; sheaths dark green and somewhat glaucous at period 
of full heading, scarcely covering the internodes; leaves colored as the 
sheaths, extremely wide, margins ciliate; ligules and auricles well developed ; 
j rhachis often very flexuous; panicles thickly branched and fruited, com- 
| pact and stiff, the branches appressed, the lowest whorl of branches 
usually issuing from a geniculate bend in the rhachis at which the nodal 
I diaphragm is wanting or rudimentary; spikelets pendant or pectinate 
in attitude, 2-3-grained; glumes dark green, somewhat glaucous at period 
of full heading, medium in length (23-27 mm.), 8-9-nerved, usually 
9-nerved; grains black or brown, somewhat elongate, outer grains 16-20 
i mm. long, long-pointed; lemma of the outer grain glabrous, with 7-8 
prominent nerves; awns usually present, dark-colored and twisted at the 
base, sometimes slightly geniculate; basal hairs usually wanting, although 
often present, short and weak; rhachilla of the outer grain 2.5-3.5 mm. 
1 long, usually carrying a few short, stiff hairs. Plants 8-10 dm. tall; 
late in maturing.

(Salzer's), Black Prolific (Salzer's), Black Tartar, Danish White, Garton's 
Black, Probst eier, Sensation. 
Golden Giant (Plate XXI, 2, and fig. 13). — Culms erect in early growth, 
medium large, coarse, usually glabrous but in some cases slightly hairy near 
the nodes; sheaths dark green and somewhat glaucous at period of full 
heading, fully covering the internodes; leaves colored as the sheaths, me- 
dium wide, margins glabrous; ligules and auricles wanting; rhachis usually 
straight but may occasionally be slightly flexuous; panicles unilateral, 
sparsely branched and fruited, slightly drooping at the apex, the 
branches appressed, the lowest whorl of branches always issuing from 
a normal node; spikelets pendant or pectinate in attitude, 2-3-grained; 
glumes dark green and somewhat glaucous at period of full heading, 
rather short (20-25 mm.), 9-10-nerved, usually 9-nerved; grains bright 
yellow, elongate, outer grains 18-22 mm. long, long-pointed; lemma 
of the outer grain glabrous, with 7 obscure nerves; awns usually present, 
dark-colored and slightly twisted at the base; basal hairs usually wanting,
