This makes the third species in the green-banded group, the others being 
C. cyaneus A. Nels. and C. macrocarpus Dougl. The latter is the nearer 
relative to the species now proposed. C. bruneaunis is easily distinguished by 
the rather tortuous stems, the different color and marking of the flowers, and 
the glabrous petal faces. 
0. 1881, found in chipped lava, high on the canyon sides of the “Hot 
Hole” of the East Bruneau, Owyhee County, Idaho, is the type. 
Clematis aurea, n. sp.—Glaucous, climbing freely by the 
petiolules: stems glabrous, striate: leaflets broadly to narrowly 
lanceolate, petiolate, pale green, irregularly incisely dentate, 
acuminate-cuspidate, midvein prominent beneath: bud green, 
drooping, erect in anthesis, the four sepals then golden yellow, 4-5 
cm. long, oblong, obtuse, cuspidate, rather thick, prominently 
nerved, glabrous except for an incurved villous margin: the 
pubescent filaments dilated, 8-1omm. long, all antheriferous; 
anthers linear, about 5mm. long, obtuse, minutely cuspidate: 
achenes pubescent, the persistent black styles filiform, only moder- 
ately white plumose throughout, 4-5 cm. long. 
Collected in July 1909, at Challis, Custer County, Idaho. It was locally 
plentiful, clambering over rosebushes, etc., along a stream, and attracted 
attention by its unusual color and beauty. It is a member of the section 
ViornA, though with sepals scarcely leathery. In aspect the plant more nearly 
resembles some members of the section ATRAGENE. 
Delphinium megacarpum, n. sp.—Much resembling D. 
Andersonii Gray, having a similar fascicle of Jong thickened woody 
roots and a strict mostly simple few-leaved stem: basal leaves 
petioled, from puberulent to nearly glabrous, suborbicular in outline, 
cuneately divided or parted, the lobes cleft into linear divisions; 
the stem-leaves rather remote, gradually reduced in size and num- 
_ ber of lobes, puberulent or more usually sparsely hirsute-ciliate, the 
bracts and base of petioles conspicuously so: stems rather stout, 
2-5 dm. high, at first cinereous-puberulent to the base, becoming 
glabrate below in age: inflorescence narrow, racemose and usually 
with one or more slender erect floriferous branchlets from the upper- 
most axils: flowers dark blue: calyx softly hirsute, spur longer 
than the sepals and: these exceeding the petals: carpels puberulent 
even at maturity, linear-oblong, 20-25 mm. long, erect and parallel,
