DESCRIPTION OF MEDICINAL PLANTS. 
ALISMACEJE. 
Alisma Plantago, L. Water-Plantain. Herb growing in 
marshes, with scape-like stems, sheating leaves and perfect 
flowers; perianth of 3 herbaceous, persistent sepals and as 
many conspicuous white deciduous petals, which are invo- 
lute in the bud ; stamens 6, ovaries many, on a flattened re- 
ceptacle, forming flattened, coriaceous achenes, which are 
dilated and 2-3 keeled on the bark. Roots fibrous. Leaves 
all from the root, several ribbed. Scape with whorled, 
panicled branches. FI. June-July. Everywhere in stag- 
nant waters. Collect the rhizome. 
GRAMINEiE. (Grass Family.) 
Anthoxanthum odoratum, L. Sweet Vernal Grass. Low, 
slender perennial, very sweet scented in drying. Flowers in 
a contracted, spike-like panicle. Glumes 5, the third and 
fourth empty, hairy, 2-lobed and awned on the back, the 
flowering glum and palet small, hyaline and obtuse; basal 
glumes persistent, very thin, acute-keeled, the lower half as 
long as the upper. Squamulae none. Stamens 2. Spikelets 
(brownish or tinged with green) spreading at flowering time ; 
one middle glum bearing a bent awn from near the base, the 
other short-awned below the tip. Naturalized from Europe 
in the Northern States, but rare in our meadows. With the 
exception of the upper counties of East Tennessee, our ter- 
ritory seems to be beyond the southern limits of its range. 
A homeopathic remedy. 
Lolium temulentum, L. Bearded Darnel. An annual grass; 
culm 1J-2J° high, spikelets many-flowered, sessile on op- 
posite sides of a zigzag-jointed, channeled rhachis, forming a 
spike, placed edgewise ; outer glumes fully equalling the 5-7 
flowered spikelet; awn longer than the flower, long. Con- 
tinually introduced, with imported seeds, into grain fields, but 
not naturalizing like its congener L. perenne, which is get- 
ting quite frequent. It is used in Homeopathy. 
Agropynum repens, Beauv. Quick Grass. Perennial grass hav-
