In the type of D. luteus the flowers are of a deeper yellow than in the plant 
of the Rio Grande region. Following his description of D. mogollonicus, Doctor 
Greene says: “All white-flowered material from New Mexico, from Las Cruces 
to the upper Gila, belongs here.” Asa matter of fact, none of our plants have 
white flowers, but in all both the calyx and corolla are a pale, clear yellow. 
This fades on drying, so that the flowers often appear white in old specimens. 
Lesquerella lata Wooton & Standley, sp. nov. 
A cespitose perennial, 10 cm. high or less, from a stout, woody root; stems 
Slender, ascending or prostrate, rather densely lepidote-stellate, with but few, 
rather distant leaves; these spatulate or oblanceolate, obtuse, thick, tapering 
at the base into a Slender petiole, lepidote-stellate on both surfaces, 138 to 30 
mm. long, 4 to 9 mm. wide, the basal leaves longer and on longer petioles; 
racemes 3 to 4 em. long, rather densely many-flowered ; pedicels slender, spread- 
ing, or reflexed in age, 7 mm. long; sepals oblong, 3.5 mm. long; petals 6 or 7 
mm. long, bright yellow; capsules oblong to obovate, thinly lepidote-stellate, 3 
mm. high, short-stipitate, much surpassed by the very slender style, 
Type. in the U. S. National Herbarium, no. 563020, collected somewhere in 
the Lincoln National Forest in 1903, by Mr. Fred G. Plummer. Here, too, 
belong young specimens collected by E. O. Wooton on White Mountain Peak, July 
6, 1895, at an altitude of about 2,880 meters. 
From our other species with pubescent capsules this is easily separated by its 
broad Jeaves, small capsules, and very long styles. 
Lesquerella pinetorum Wooton & Standley, sp. nov. 
Perennial from a rather slender root; stems clustered, slender, ascending, 10 
to 20 cm. high, lepidote-stellate but not very densely so, leafy, the leaves not 
crowded ; basal leaves spatulate, obtuse, long-petioled: cauline leaves spatulate 
or oblanceolate, obtuse or acutish, entire or slightly undulate, tapering gradu- 
ally at the base into a winged petiole, the whole leaf 20 to 30 mm. long, 3 to 7 
mm. wide; racemes long, many-flowered, dense ; pedicels about 8 mm. long, erect, 
stout; petals bright yellow, obovate, clawed, 6 or 7 mm. long; sepals oblong, 4 
mm. long, densely lepidote-stellate; capsules nearly spherical, 3.5 mm. long, not 
compressed, glabrous, not stipitate; style slender, slightly longer than the cap- 
sule; seeds about 5 in each capsule. 
Type in the U. S. National Herbarium, no. 561847, collected on a dry hillside 
under pine trees at Gilmores Ranch on Eagle Creek in the White Mountains, 
August 25, 1907, Wooton & Standley (no. 3460). Transition Zone; altitude about 
2220 meters. The plant was also collected at Gilmores Ranch, July 29, 1901, 
by E. O. Wooton, and apparently the same is a specimen from the top of White 
Mountain Peak, collected by E. O. Wooton, August 16, 1897. 
The species is nearest L. fendleri, but is not nearly so densely pubescent—in- 
deed, the plants appear green rather than whitish; the leaves, too, are much 
broader and thinner, and the capsules are smaller. 
Lesquerella praecox Wooton & Standley, sp. nov. 
A dense, cespitose, branched perennial, 4 to 6 cm. high, from a thick, woody 
root ; leaves numerous, much crowded upon the short, stout stems; leaves linear- 
oblanceolate, 25 to 80 mm. long, 2.5 mm. wide or less, acutish, thick, white with 
a dense, lepidote-stellate pubescence, attenuate to the base; pedicels few, axillary 
or all arising from the tips of the branches, never racemose, 20 mm. long, erect, 
usually shorter than the leaves; sepals linear, 5 mm. long, sometimes persistent ; 
petals bright yellow, obovate, 7 or 8 mm. long; capsules spherical or nearly so, 
not compressed, slightly channeled along the edge of the septum, glabrous, not 
Stipitate, 5 mm. high,
