Stem creeping extensively a little beneath the surface of the ground, throwing up erect 

 branches 3-5 inches high. Leaves 3-6 toward the summit of each branch, about an inch 

 long, thick and coriaceous, often purplish ; the margin slightly revolute, rather remotely 

 serrulate, particularly toward the base ; the serratures appressed, and tipped with a short 

 bristle : petiole very short. Pedicels nearly half an inch long, with two roundish bracteoles 

 close to the flower ; the segments semiovate and ciliate. Corolla one-third of an inch long, 

 white, obtuse, 5-angled ; the teeth of the orifice revolute. Stamens included ; filaments rather 

 broad : anthers large ; the lobes parallel, with 2 short incurved awns at the summit. Ovary 

 globose, surrounded at the base with a 10-toothed torus : style cylindrical : stigma small, 

 somewhat capitate. Capsule completely enclosed in a large red berry-like calyx. Seeds 

 ovoid, smooth. 



Woods and rather dry swamps, particularly in sandy soil ; common. Fl. May - July. 

 Fr. Octobcx. The whole plant has an agreeable spicy flavor, somewhat resembling that of 

 Sweet Birch. It yields an essential oil, which is used as a stimulant, cordial and emmena- 

 gogue, and is sold under the name of Oil of winlcrgreen. An infusion of the leaves is also 

 used for the same purpose. The berries arc edible, and have a pleasant flavor, but arc dry. 

 The oil is very remarkable in its chemical composition, having recently been ascertained by 

 M. Cahours to be a salycilite of the oxide of methyl, or composed of an acid called the 

 talycilic (hitherto only found in the oil of Spiraa), united with the ether of wood-spirit 

 {methylic ether).
