or often tinged with blue, the second flower subtended by a petioled leaf. Hook. 

 FL Bor.-Am. i. 22, t. 10. 



At Sitka, and southward in the Rocky Mountains to New Mexico and Utah. Not yet found 

 in California. 



2. C. biflora, DC. Leaves round-reniform (broader than long), with broad often 

 overlapping basal lobes, crenate or obscurely so : flowers rarely 2, the lower sub- 

 tended by a sessile leaf or bract, greenish white or yellowish. 



In the Sierra Nevada, subalpine, and northward to British Columbia. The Californian speci- 

 mens seem to differ from the more northern ones only in their less distinct crenation, the veinlets 

 often glandular-excurrent. 



6 a . COPTIS, Salisb. GOLDTHREAD. 



Sepals 5 to 7, petal-like, deciduous. Petals narrowly linear, mostly cucullate. 

 Stamens 10 to 25. Carpels 3 to 8, in fruit folliculate and stipitate, 4-8-seeded. 

 Seeds crustaceous, shining. Low smooth evergreen perennials, with slender run- 

 ning rootstocks, subcoriaceous ternate radical leaves, and scape-like stems bearing 



1 to 3 whitish flowers. 



Four species are found in eastern Asia, one of which ranges also from Arctic America to the 

 northern Atlantic States. The following are peculiar to the Pacific Coast. 



1 . C. asplenif olia, Salisb. Leaves ternate, biternate or ternate-quinate, the ovate 

 divisions deeply 3 5-lobed and acuminately toothed : scape equalling or exceeding 

 the leaves, 3 to 12 inches high : sepals very narrowly linear-lanceolate, 4 or 5 lines 

 long, spreading or reflexed ; petals a third shorter, nearly filiform, dilated and cucul- 

 late in the middle : fruit 4 to 6 lines long, exceeding the stipe. Hook. Fl. Bor.- 

 Am. i. 23, t. 11. 



Mendocino County (G. R. Vasey) ; Cascade Mountains, Linn County, Oregon ( W. C. Cusick) ; 

 Columbia River (Hall) ; Sitka. The Alaskan specimens have the leaves generally more divided 

 than those of Oregon and California. 



C. OCCIDENTALS, Torr. & Gray (Chrysocoptis occidentalis, Nutt. in Journ. Philad. Acad. vii. 9, 

 t. 1), is still imperfectly known but is supposed to be distinguished by its linear petals, similar 

 to the sepals and not cucullate. The leaves are ternate, as in the simpler forms of the last. The 

 seeds (a little more than a line long) are perhaps larger. The roots are said to be bright yellow. 

 It has been collected in the Umpqua Mountains, Oregon (Pickering), and north to Northern 

 Idaho, Lyall. 



7. ISOPYRUM. 



2. I. Stipitatum, Gray. Eoots fleshy-fibrous and fascicled (as in other species) : 

 radical leaves twice ternate, the leaflets on slender petioles, mostly 3-lobed or -parted ; 

 segments oblong, acutish : stems 3 or 4 inches high, equalling the leaves, 1 - 2-leaved 

 at the summit and bearing a single flower : peduncle thickened at summit : sepals 

 4 or 5, oblong, 3 lines long : follicles shortly stipitate, broad-oblong, very obtuse, 

 3 lines long and 3 - 4-seeded. Proc. Am. Acad. xii. 54. /. Clarkii, Kellogg, Proc. 

 Calif. Acad. vii. 131. 



Near Yreka, Siskiyou County, very common on hillsides under bushes (Rev. E. L. Greene) ; 

 Mendocino County, J. H. Clarke. Flowering in April. 



I. HALLII, Gray, Proc. Am. Acad. viii. 374, of the Columbia Valley, is 1 or 2 feet high, with 

 large biternate leaves, the peduncle bearing a subumbellate corymb of 7 to 9 large flowers : follicles 



2 lines long, ovate-oblong, acuminate.

6. D. glaucum. (Substitute for D. scopulorum, Gray.) Tall and stout, 

 glabrous and more or less glaucous : leaves large, laciniately lobed and toothed, the 

 segments mostly acuminate, the uppermost leaves sparingly lobed or entire and nar- 

 rowly lanceolate : flowers pale blue, numerous in a narrow raceme, upon slender and
