454 Nasu: REVISION OF THE FAMILY FOUQUIERIACEAE 
in the district of Tehuacan, State of Pueblo, from which place 
Pringle also secured the same plant many years later. Lieb- 
mann’s excellent plate and description leave no doubt as to the 
identity of his plant with the one of H.B.K. 
3. Fouquieria Macdougalii sp. nov. 
A much-branched tree, reaching a height of 7 m. and a trunk 
diameter of 1-2 dm., with bark yellowish green on the trunk and 
brown on the spiny branches, the spines 1-2 cm. long, and termi- 
nal slender panicles of few bright red flowers. Leaves on the new 
growth 6-8 cm. long, petioled ; blade 3.5-4 cm. long and about I 
cm. wide, acute at the apex, and rather abruptly narrowed into a 
petiole of the same length: fascicled leaves in the axils of the 
spines gradually narrowed into a sessile base, 3.5—4 cm. long and 
about I cm. wide: panicle slender, 7-10 cm. long, its delicate 
simple branches widely spreading, the lower ones 3-4 cm. long 
and bearing 2-4 flowers on slender pedicels which are 1-2 cm. in 
length and abruptly thickened at the apex: flowers few: sepals 
broadly oval, about 6 mm. long, the outer two acute, the inner 
three rounded and apiculate at the apex: corolla about 2.5 cm. 
long, the tube cylindric, 3-4 mm. in diameter, the lobes broadly 
ovate, erect, acute, about 5 mm. long : stamens 10, exserted, the 
filaments red above, white below, broader and dorsally compressed 
near the base, the interior surface of this compressed portion gla- 
brous, the exterior surface pubescent with long stout hairs which 
gradually increase in length upward and extend but a short dis- 
tance on the rounded part of the filament which is glabrous to the 
summit, the anthers 2-3 mm. long: styles exceeding the stamens, 
united almost to apex: capsule about 2 cm. long. 
Type specimen from living plants, collected at Torres, Mexico, 
in 1902, by MacDougal, no. 28, which flowered in the conserva- 
tories of the New York Botanical Garden in June, 1903.

This plant was first secured by Thurber at Rayon, about 
eighty miles north of the place where it was recently obtained by 
Dr. MacDougal. Thurber's plant was distributed as /. 57771054, 
from which it differs materially. It is evidently, however, the
