 4— G feet hi«;h. Leaven alternate, nearly sessile, glabrous, strongly 

 vemed, sprinkled on the under surface with glandular atoms Flow^ 

 ers in axillary, leafless spikes, which toward tlie summit of the branches 

 become densely crowded. Calyx 1 leaved, 5 parted, persistent, gla- 

 brous; tlie segments concave, acute. Filaments longer than the ca- 

 lyx, transparent. Jlntliers incumbent, recurved, yellow. Qenn 

 superior, turbinate, truncate. Strjle 3 cleft, as long as the stamens. 

 Stigmas simple, acute. 



This is probably our only indigenous species. The others have all 

 been introduced. Specimens of this plant which I have received from 

 the Eastern States differ from ours by leaves less rugose, dentate not 

 sinuate, and flowers in detached clusters (glomerules), not in pani- 

 culate spikes as with us. 



Grows in loose soils. Common ia pastures. 



Flowers June—August. JenisaUm Oak. 



The expressed juice of the leaves was formerly much used in family 

 practice as a preventive of worms in children. 'An ounce or two was 

 given on an empt^ stomach once or twice a week. The health of puny 

 children is sometimes improved by it. The essential oil of the seed 

 has been much extolled as a vermifuge.
