 or ascending, sometimes stolon-like, becoming stout in old plants; scapes 

 slender, erect, naked or with one or two scarious bracts or sometimes 

 with a single^ petioled leaf near the base, glabrous or with few, scattered, 

 stiff hairs, and glandular puberulent, 1 — 4 dm. high; leaves cordate-ovate 

 or sometimes nearly orbicular, crenately several-lobed, very sparsely hirsute 

 with white hairs on both surfaces or quite glabrous, 2.5 — 7 cm. long, 

 2 — 6 cm. wide; petioles slender, 3—14 cm. long, sparingly retrorse-hirsute, 

 or sometimes becoming quite glabrous in age; racemes simple or frequently 

 .with 2-flowered cymes, 3 — 12 cm. long; bracts deltoid to obovoid and 

 bilobed, glandular fringed; pedicels 2 — 4 mm. long, glandular-puberulent, 

 with two minute bracteoles at the base; flowers yellowish green, 6 — 9 mm. 

 across in anthesis; axis saucer-shaped; sepals triangular, strongly reflexed, 

 about 1 mm. long; petals yellowish green, spreading or slightly reflexed, 

 2—2.8 mm. long, pectinate-pinnatifid, with 7 — 10 divisions; stamens 5, 

 very short, inserted at the base of the petals, anthers reniform; disk 

 mostly purplish brown, nearly covering the ovary; ovary inferior, styles 

 short and spreading, stigmas bilobed; capsule depressed-ovoid, evaginating 

 in fruid; seeds numerous, black and shiny. 



On banks of cold streams, in swamps and bogs in the mountains. 

 Distributed from southern Colorado far north in the Rocky Mountains and 

 from eastern middle California and western Nevada northward in the 

 Sierra Nevada mountains into the Coast and Cascade Ranges northward 

 to Alaska. 



This widely distributed species is somewhat variable as to size and 

 hairiness of leaf, length of petioles, etc. the following forms are note- 

 worthy: 



Forma stolonifera. — Producing leafy runners, leaves nearly orbi- 

 cular, sometimes acutish, with a closed sinus at the base, crenately many- 

 lobed, prominently hirsute on both sides and on the petioles, frequently 

 with a single small cauline leaf; petioles longer than in the species; the 

 second flower of the 2-flowered cymes often borne some distance up on 

 the pedicel of the first flower. 



In swamps, upper valley of the Nesqually, Mt. Ranier, C. D. Allen, 

 No. 5. E. C. Smith, Mt. Ranier, alt. 4000 ft. Aug. 1880, — with very 

 coarsely- dentate leaves. These may be the same as Peetiantia lahflora
