valve awned. Neclary linear, 2-parted. Stig- 
mata nearly sessile, 
Flowers polygamous, one masculine, the other herma- 
_phrodite, paniculate. 
Species. 1. H. lanatus, 2. striatus? 3. fragrans, (called 
Sweet-gra8s, and Sencka-grass, nearly allied to the Holeus 
oderatus; certainly not a congener with the #. /anatus and 
Hi. mollis, but apparently a Melica.) 
’” Grasses of Europe, with the exception of the H. fra- 
grans. The H. lanatus is now naturalized in the United 
States. 
94. SORGHUM. L. (Broom-grass.) ‘x 
Flowers polygamous, by pairs, the herma- 
_ phrodite flower sessile, the masculine or neuter 
_ pedicellate. HERMAPHRODITE. Calix 2-valy- 
ed. Corolla 3-valved; the 2d valve awned, the 
_ 3d connecting with the villous nectary. Corolla 
of the male flower awnless. Seed large. 
» __ Culm tall, flowers diffusely paniculate, leaves expand-_ 
ing. Seed sufficiently large to be cultivated for food 
» «somewhat resembling millet. 
_. Spectres. 1. Hf. bicolor. (By Persoon considered a varie- 
ty of ne S. vulgare; cultivated around Lancaster, accord. 
ing to Dr. W. Barton, who bas been induced to recommend 
.. *it to public economy, as a substitute for chocolate or cot- 
fee, when parched.) 2. succharatum. (Extensively culti- 
vated in the United States, though no where naturalized. 
Its large panicles are used for brooms; the ih is given 
to poultry, and might probably answer the same purposes 
as that of the §. dicolor. The whole plant is highly sac- 
__charine, and attempts have been made in France and 
elsewhere to extract sugar from it; but without sufficient 
success. ) Pi ia f 
_ OF this genus there are only 4 species described by 
Persoon; 2, if not 3, in‘India, and 1 in Syria;—the .S. dico- 
dor is a native of Persia.
