tude about 1,230 meters. Also gathered by the same collector at the same place, 
August 5, 1899, 
The type collection was distributed as D. holosteoides Benth., a plant of 
Lower California. Our species is cited from western Texas under this name 
in the Synoptical Flora. That species, however, has much narrower, acutish 
leaves, and puberulent pedicels, Another related species is D. crassifolia Benth., 
also of Lower California, but that has much thicker, fleshier leaves, and is a 
very densely branched perennial. 
Besides the New Mexican specimens cited above we have a sheet collected by 
Havard on the Tarlinga River in western Texas. 
FUMARIACEAE.

slender, few-flowered racemes; bracts 12 to 25 mm. long, broadly oblanceolate, 
4 to 9 mm. wide, acute or acuminate, thin; corolla bright yellow, about 15 mm. 
long; spur horizoutal, thick, half as long as the body; fruit 20 to 30 mm. long,

Type in the U. 8. National Herbarium, no. 690256, collected at Cloudcroft

This Capnoides is related to C. aurewm, but may be distinguished by its very 
large bracts and by the presence of pinni at the base of most of the petioles. It 
is, besides, a rather more slender plant, with more dissected and delicate leaves. 
RANUNCULACEAE, 
Clematis neomexicana Wooton & Standley, sp. nov. 
A woody climber, one or two meters high; stems striate, finely pubescent ; 
leaves pinnately 5-foliolate, on petioles 4 to 6 cm. long: leaflets ovate in outline, 
35 to 60 mm. long, 25 to 45 mm. wide, shallowly 3-lobed, the terminal lobe acute 
to obtuse, never long-attenuate, the lobes entire or coarsely crenate with obtuse 
teeth; leaflets bright green, slightly paler beneath, finely and loosely pubescent 
on both surfaces; flowers in a loose, few-flowered panicle, on a peduncle about 
5 cm. long; pedicels about 25 mm. long; sepals oblong-spatulate, obtuse, finely 
pubescent, 12 mm. long, much exceeding the stamens: carpels densely hairy, 
tapering gradually into the plumose tail 15 to 35 mm. long.
