120 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Type in the U. S. National Herbarium, no. 686447, collected on dry hills near 
the north end of the Carrizo Mountains, July 31, 1911, by Paul C. Standley (no. 
7481). 
Related to A. confertifolia, but with dentate bracts not rounded at the 
apex, much smaller leaves, and sessile fertile flowers. 
AMARANTHACEAE. 
Gomphrena viridis Wooton & Standley, sp. nov. 
Low, cespitose perennial from a long, woody root; basal leaves bright green, 
obovate to elliptic-oblong. the blades 3 to 7 em. long, obtuse or acutish, gradually 
narrowed at the base ‘into a long, slender petiole, sparingly strigose with fine 
short hairs or nearly glabrous on the upper surface; stems slender, prostrate 
or spreading, tortuous, 3 to 10 cm. long, cinereous-puberulent to thinly sericeous ; 
cauline leaves a single pair, in outline like the basal ones, or broader, often 
orbicular, on slender petioles 5 to 10 mm. long; peduncles terminal, slender, 35 
to 70 mm. long, loosely sericeous but not densely so; heads subglobose, 8 to 20 
mm. high; bracts scarious, white, ovate, acute; calyx lobes ljinear-oblong or 
oblanceolate, obtuse, entire, with a broad green midvein and scarious white 
margins, densely long-hairy. 
Type in the U. 8. National Herbarium, no. 660403, collected on Hanover 
Mountain, Grant County, July 31, 1911, by J. M. Holzinger. 
ADDITIONAL SPECIMENS EXAMINED: 1851-2, Wright 1753: base of San Luis — 
Mountains, up to 1800 meters, September 5, 1893, Mearns 2133. 
The species also occurs in southeastern Arizona. 
Closely related to Gomphrena caespitosa, but with, green, narrower leaves, 
Sparse pubescence, more conspicuously petioled cauline leaves, and promi- 
nently green calyx lobes. 
ALLIONIACEAE. 
Allionia linearifolia filifolia Standley. 
Allionia gracillima filifolia Standley, Contr. U. 8S. Nat. Herb. 12: 340, 1909. 
An examination of the type of Orybaphus linearifolius S. Wats. shows that 
Allionia graciilima Standley is a synonym of that species. 
Allionia subhispida (Heimerl) Standley. 
Mirabilis linearis subhispida Heimerl, Ann. Cons. Jard. Genéve 5: 186. 1901. 
Allionia linearis subhispida Standley, Contr. U. S. Nat. Herb. 12: 342. 1909. 
This was well described by Doctor Heimerl. It may be distinguished from 
A. linearis by its abundant hirsute pubescence present on all parts of the 
branches. It has been collected in New Mexico several times recently. 
PORTULACACEAE. 
Talinum angustissimum (A. Gray) Wooton & Standley. 
Talinum aurantiacun angustissimum A, Gray, Pl. Wright. 1: 14. 1852. 
This has long been confused with T. aurantiacum, a larger, stouter, more 
succulent plant with larger, orange-colored flowers. It is difficult to distinguish 
the two by herbarium specimens, but no one can confuse them in the field. 
Both species have been confused with 7. lineare H. B. K., a plant known only 
from central Mexico. 
Talinum longipes Wooton & Standley, sp. nov. 
Root slender, very long and tortuous, the crown covered with the persistent 
bases of dead leaves; leaves humerous and crowded, appearing basal, 12 to
