WOOTON AND STANDLEY—NEW PLANTS FROM NEW MEXICO. 128 
The plant is near C. ligusticifolia, but differs in its pubescent leaflets and 
stems, the different form of the leaflets, the shorter tails of the carpels, and the 
shape of the ecarpels. It may be Clematis ligusticifolia californica 8S. Wats., 
but the Californian material seems to be of a different species. 
Myosurus egglestonii Wooton & Standley, sp. nov. 
Plant glabrous; leaves linear or linear-oblanceolate, obtuse, thick and some- 
what fleshy, 8 to 14 mm. long; scapes solitary or numerous, very short, 2 to 5 
mm. long, slender; sepals scarious, linear-oblong, obtuse, 38 mm. long, with a 
slender spur 1 mm. long; petals not seen, apparently wanting; heads of achenes 
elongated-oblong, 8 to 18 mm. long, 2.5 mm. in diameter; achenes small, the 
backs suborbicular, with a low, obtuse border, strongly keeled and with a beak 
from once to twice as long as the diameter of the back, the beak ascending. 
Type in the U. S. National Herbarium, no. 660739, collected on a mesa on the 
road between Tierra Amarilla and Park View, Rio Arriba County, altitude 
2,250 meters, April 18 to May 25, 1911, by W. W. Eggleston (no. 6472). 
Evidently related to M. cupulatus, but readily distinguished by the very 
short fruiting spikes, the short scapes, and the elongated beaks of the achenes. 
In size the plant suggests V/. alopecuroides Greene, of California, but the achenes 
of the two are very dissimilar.

Arabis angulata Greene, sp. noy. in herb. 
Perennial from a rather thick, woody root; stems simple, clustered, slender, 
erect, 25 to 40 em. high, pubescent below with few branched hairs, glabrous 
above; basal leaves oblanceolate to spatulate, 25 to 85 mm. long, 11 mm. wide or 
less, obtuse, with a few coarse teeth, rather bright green, pubestent with 
branched hairs; cauline leaves rather remote, smaller, oblong-lanceolate to 
almost linear, sessile, auricled, the auricles mostly acute, the lower leaves pubes- 
cent, the upper glabrous, obtuse or acute; racemes elongated, slender; pedicels 
slender, divergent, 12 mm, long or less; sepals purplish, oblong, obtuse, 2.5 mm. 
long, with scarious margins, usually with a few hairs; petals twice as long, 
purple; pods slender, 45 to 60 mm, long, 1 mm, wide, curved upward, glabrous; 
seeds in a single row. 
Type in the U. S. National Herbarium, no, 495141, collected at Mangas 
Springs, April 9, 1908, by O. B. Metcalfe (no, 12). Altitude 1,430 meters. 
A species of the group to which belongs A. fendleri, distinguished especially 
by its very long, slender pods conspicuously curved upward. 
Doctor Greene recognized this as an undescribed species when Mr. Metcalfe’s 
plants were being named, and the plants were dist ributed under the name here 
given to them; a description, however, has not been published until now. 
Arabis porphyrea Wooton & Standley, sp. nov. 
Perennial from a long, slender, woody root; stems slender, erect, pubescent 
below with branched hairs, glabrous above, purplish; basal leaves 40 mm, long 
or less, spatulate or oblanceolate, stellate-pubescent, long-petioled ; lower cauline 
leaves petioled, oblanceolate, obtuse, stellate-pubescent, the upper ones linear or 
linear-oblong, acute, glabrous, sessile and auricled, reduced; pedicels divaricate 
or reflexed, 10 or 12 mm. long, slender; sepals oblong, obtuse or acutish, 8 mm.
