454 Nash : 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 deHcate 

 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 : coroUa 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 F. spinosa, 

 from which it differs materially. It is evidently, however, the
