PYROLACEAE. 273 



Hypopitys hypopitys (L.) Small. Whole plant reddish or yellowish, some- 

 what pubescent, 10-40 cm. high;. scale-like leaves lance-ovate, entire or slightly 

 erose, scattered above, densely arranged below; flowers 3-20, racemose, 

 nodding at first, erect in fruit; terminal flower S-merous, the lateral ones 

 3-4-merous; style terete; stigma disk-like; pod subglobose. 



In coniferous woods, especially in the mountains at low altitudes, common. 

 H. brevis Small described from specimens collected at Independence Valley, 

 Oregon, by Craig, is said to differ by having the style much dilated upward 

 and the stigma funnelform. 



Hypopitys fimbriata (Gray) Howell. Very similar to H. hypopitys but 

 the upper scales, the bracts and the sepals laciniate or fimbriate. 



In coniferous woods, rare. Reported from Mount Arrowsmith, Vancouver 

 Island, and Chilliwack, British Columbia, Macoun; Cascade Mountains of 

 Oregon; not yet known to occur in Washington. 



372. MONESES. 



Low perennial glabrous herbs; flowers solitary on a slender 

 scape, drooping, white or pink; petals 5, distinct, widely spread- 

 ing, orbicular; stamens 10; filaments not enlarged in the middle, 

 naked; anthers conspicuously 2-horned; style exserted; stigma 

 large, peltate, with 5 short radiating lobes; ovary globose, 4-5- 

 celled; ovules numerous; capsule subglobose, 4-5-celled, 4-5- 

 valved; seeds numerous, minute. 



Moneses uniflora (L.) Gray. Rootstock very slender; stems erect, bearing 

 2—1 pairs or whorls of leaves; leaves obovate or orbicular, obtuse, finely crenate 

 or dentate, 8-20 mm. long, narrowed at the base, the petioles shorter; 

 scapes 5-12 cm. high, 1-flowered, usually bearing a solitary bract; flowers 

 white, nodding, 12-20 mm. broad; capsules erect, 6-8 mm. broad. 



Coniferous woods in the mountains. The Pacific Coast plant has by some 

 botanists been considered distinct under the name M. reticulata Nutt. 



373. CHIMAPHILA. Pipsissewa. 



Low nearly herbaceous perennials; leaves irregularly opposite, 

 whorled or scattered, coriaceous, short-petioled, serrate; flowers 

 in corymbs on a leafy stem; petals 5, widely spreading, orbicular; 

 anthers 2-horned; stigma large, peltate, with 5 narrow and con- 

 spicuous radiating lobes; valves of the capsule naked. 



Flowers many; leaves cuneate-oblanceolate, numerous. C. umbellata. 



Flowers few; leaves ovate or oblong-lanceolate, few. C. menziesii. 



Chimaphila umbellata (L.) Nutt. (C. occidentalis Rydb.) Stems 15-30 

 cm. high, erect from horizontal rootstocks; leaves evergreen, leathery, cuneate- 

 oblanceolate, acute, serrate, 2-4 cm. long, short-petioled, glabrous or minutely 

 puberulent; flowers 4-8, pink, about 1 cm. broad, in terminal corymbs; fila- 

 ments bearded on the margins; capsule 6-8 mm. broad. 



Deep coniferous woods, common. 



Chimaphila menziesii (R. Br.) Spreng. Stems 10-15 cm. high; leaves few, 

 ovate or oblong-lanceolate, acute at each end, serrulate, 1-2.5 cm. long, the
