STANDLEY—TROPICAL AMERICAN PHANEROGAMS. 181 
recognized as a distinct species, £. arborea Small,’ but it seems to differ from 
typical EH. herbacea only in habit. 
14, Erythrina flabelliformis Kearney, Trans. N. Y. Acad. 14: 32. 1894. 
Erythrina purpusi T. S. Brandeg. Zoe 5: 158. 1903. 
TYPE LOcALITy: Near Fort Huachuca, Arizona. 
DISTRIBUTION: Sonora (Rose, Standley & Russell 12707, 12943; Mearns 335, 
876; Hartman 41); Baja California (Nelson & Goldman 7241, 7353); Sinaloa 
(Palmer 771); Durango (Palmer 179); Jalisco (Rose & Hough 4774, 4811; 
Rose 2887; Pringle 7626, 8658); Zacatecas (Rose 3554, 3612); Guanajuato 
(Rose € Hough 4835) ; San Luis Potos{ (Palmer 686) ; Hidalgo (Nelson 3880; 
Pringle 68389; Rose & Hay 5301); Morelos (Rose & Hough 4346a). Also in 
southeastern Arizona and southwestern New Mexico. 
15. Erythrina goldmanii Standl., sp. nov. 
Branches fruticose, gray, sparsely pilose when young, armed with numerous 
very stout, short spines; petioles stout, bearing few stout recurved spines; 
leaflets rounded-ovate or suborbicular, 3.5 to 9 cm. long, 3 to 6.5 cm. wide, 
rounded at the base, abruptly acuminate at the apex, thick, concolorous, pilose 
when young but soon glabrate, the venation rather prominently reticulate, the 
veins armed beneath with few stout recurved spines; calyx about 1 cm. long 
and broad, glabrous or nearly so, somewhat obliquely truncate; standard 
oblong-linear, about 8 cm. long and 1 cm. wide, the wings only slightly exceed- 
ing the calyx; fruit several-seeded, 12 to 16 cm. long, deeply constricted be- 
tween the seeds; seeds 9 to 10 mm. long, scarlet. 
Type in the U. 8. National Herbarium, no. 470671, collected at San Vicente, 
Chiapas, Mexico, April 20, 1904, by E. A. Goldman (no. 870). 
A fruiting specimen, collected at La Razén, Chiapas, by Goldman (no. 1039), 
also belongs here. 
Erythrina goldmanii is closely related to EH. americana, but seems distinct 
in its larger flowers, deeply constricted pods, and aculeolate leaflets. 
16. Erythrina americana Mill. Gard. Dict. ed. 8. Hrythrina no. 5. 1768. 
Erythrina carnea Ait. Hort. Sew. 3: 8. 1789. 
TYPE LOCALITY: Veracruz. 
DISTRIBUTION: Oaxaca (Pringle 6271; Rose € Hough 4627; Conzattt 1676) ; 
Morelos (Rose & Hough 4346; Rose & Hay 5351); Distrito Federal (Pringle 
6838) ; Veracruz (Nelson 79); Yucatin (Millspaugh 306; Schott 831); Chiapas 
(Goldman 834) ; Puebla (Arséne 2872). 
A fruiting specimen from San Luis Potosf (Nelson 4386) may belong here, 
but it has very large, thin, subattenuate leaflets; the form of the calyx is not 
determinable. <A flowering specimen from Veracruz (Orcutt 3398) probably 
should be referred to EF. americana, although the flowers are smaller than is 
usual in the species. 
Erythrina coralloides DC.,? based upon Sessé and Mocifio’s plate* of a 
Mexican plant, is probably a synonym. The illustration, however, is so im- 
perfect that it is impossible to be certain that it does not represent FH. flabelli- 
formis. : 
Specimens of HE. americana have been determined as EH. corallodendron L. 
That is a West Indian species, distinguished by a broad standard and red and 
black seeds. 
The vernacular name in Puebla is “ colorin.”
