appeared to be short merely because their extremities had curled 
downward. Wittmack, in his ‘‘Gras- und Kleesamen,” Berlin, 
1873, figures the awn of H. moilis as being nearly straight, while 
the awn of H. lanatus he represents as bent outward away from 
the interior of the flower. Long awns are indicated for both the 
plants. In the text also he describes the awn of H. lanatus as 
hooked and that of H. mollis as not hooked. Schmidlin, in his 
‘** Abbildung und Beschreibung der wichtigsten Futtergriiser,” 
has a figure of H. mollis as covered with long straight awns, a few 
of which are slightly twisted ; while in his figure of H. lanatus only 
a few awns are shown anyway, and those are comparatively short, 
though with a single exception they are all straight. Jessen, in 
his ‘* Deutschlands Griiser,” gives on pp. 52 and 105 a figure of 
fH, mollis showing a long straight awn; and on pp. 56 and 106 he 
gives a figure of H. lanatus with a hooked awn, the hook looking 
inward toward the interior of the flower as was said above; but on 
p- 221, where the two species or varieties of the grass are con- 
trasted, the same figures are given again, now side by side with 
the names transposed. Here the hooked awn is credited to H. mol- 
lis and the straight awn to H. lanatus. That this transposition of 
the figures was unintentional appears from the descriptions in the 
text. On p. 106 it is distinctly stated that ‘‘ in H. lanatus a hooked 
awn often projects beyond the palet,” and on p. 222 it is said that 
‘* H. lanatus has awns which are hardly so long as the palets, while 
the awns of H. mollis are appreciably longer. In H. lanatus the 
awn is first straight and then bent, while in H. mollis it is knee- 
shaped but never curved.” In Wm. Hamm’s ‘‘ Grundztige der 
Landwirthschaft,” 2. 3824, the more strongly magnified figures of 
the flowers proper show a straight awn on H. mollis and no awn on 
H. lanatus, while the less highly magnified figures of the tufts of 
flowers seem to show straight awns in both cases. C. L. Flint, in 
his ‘* Practical Treatise on Grasses and Forage Plants,” New York, 
1857, pp. 68-70, gives the same figures as Hamm, with the excep- 
tion that for H. lanatus the magnified flower shows an awn that is 
inclined obliquely. FF lint’s description of the awn of H. lanatus 
follows that of Professor Gray, and so does Killebrew’s, in his 
‘*Grasses of Tennessee.” To cite one other authority, it was 
noticed after the foregoing observations had been made that a 
highly pertinent word concerning them had been written long be- 
fore they were made in a copy of ‘‘ Gray’s Manual,” which is kept 
in the Bussey Library. At the paragraph where Professor Gray
