[Sidenote: =Pyrola secunda= L. _One-sided Wintergreen._] Stems generally several together, from the much branched rootstock, slender, 4—10 inches high. Leaves ovate or often oval, thin, acute or rarely obtuse at the apex, rounded or narrowed at the base, crenulate-serrate, ¾—2 inches long, longer than the petioles. Flowers greenish-white, ¼ of an inch or more broad, many, at first erect but soon drooping, in a dense one-sided raceme; style straight, exserted; stamens not declined. Common in woods throughout the region at the lower altitudes; flowering during early July. [Sidenote: =Moneses uniflora= (L.) A. Gray. _One-flowered Wintergreen._] Stem bearing 1—3 pairs or whorls of leaves at the base, continued above into a bracted or naked scape 2—6 inches high. Leaves orbicular or ovate, obtuse at the apex, narrowed, rounded or sometimes subcordate at the base, rather thin, ¼—1 inch long, longer than or equalling the petioles. Flowers white, ½—¾ of an inch broad, nodding at the summit of the stem; petals spreading; capsule ¼ of an inch in diameter, about as long as the persistent style and lobed stigma; the stamens in pairs opposite each petal. In mossy spots in the woods throughout the region; flowering in early July. [Illustration: Chimaphila umbellata (L.) Nutt. (⅔ Nat.) Prince’s Pine.] [Illustration: Arctostaphylos uva-ursi (L.) Spreng. (½ Nat.) Bear-Berry.] [Sidenote: =Chimaphila umbellata= (L.) Nutt. _Pipsissewa, Prince’s Pine._] Stems extensively creeping, sending up both sterile and flowering branches 3—12 inches high. Leaves numerous, crowded near the summit of the stem, spatulate or cuneate-oblanceolate, obtuse or acutish at the apex, sharply serrate, bright green and shining, 1—2½ inches long, ¼—1 inch wide above the middle. Flowers several in an umbellate head, waxy white or pink, the form of the region being usually bright, rosy pink, ½ an inch or more broad, petals spreading with the rosy pink anthers opposite them in pairs; capsule about ¼ of an inch broad surmounted by the short style. Locally abundant throughout the region; flowering during July. ERICACEÆ _Heath Family_ In our species, shrubs with simple leaves and perfect flowers; calyx free from the ovary 4—5-parted, mostly persistent; corolla regular, 4—5-toothed, -lobed or -parted; stamens usually as many or twice as many as the corolla lobes; anthers 2-celled, attached to the filaments by the back or base, the sacs, often prolonged upwardly into tubes; ovary 2—5-celled; fruit a capsule, berry or drupe.
