178 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
1. Erythrina glauca Willd. Ges, Naturf. Freund. Berlin Neue Schrift 3: 428. 
1801. 
Erythrina patens DC, Prodr, 2: 414. 1825, 
Duchassaingia glauca Walp. Ann. Bot. 2: 424, 1851. 
TYPE LOCALITY : Caracas, Venezuela. 
DIsTRIBUTION: Guatemala (Heyde & Luar 6329); Nicaragua (Shannon 5028, 
Baker 690) ; Panama (Pittier 2571, 6942, 2744; Fendler 81; Maxon 4790; Chris- 
topherson 142; Goldman 1853). Also in Cuba, Porto Rico, the Lesser Antilles, 
and Venezuela, 
Erythrina patens was based upon one of Sessé and Mocifio’s plates,’ which 
agrees exactly with the present plant. De Candolle gives the habitat as Mexico, 
but the writer has seen no Mexican specimens. Perhaps the plate was drawn 
from Guatemalan or Porto Rican specimens. 
2. Erythrina darienensis Standl, Contr. U. S. Nat. Herb. 18: 108, 1916, 
DISTRIBUTION : Known only from the type locality, near Pauarandé, southern 
Darién, Panama. ‘ 
3. Erythrina breviflora DC. Prodr, 2: 413. 1825. 
Erythrina latifiora Sessé & Moc. Pl. Nov. Hisp. 15, 1887, 
Erythrina petraea T. S. Brandeg, Zoe 5: 247. 1908. 
TYPE LOCALITY: Ayacapixtla, Mexico. 
DISTRIBUTION; Jalisco (Rose & Painter 7511); Guanajuato (Duges 2) ; More- 
los (Pringle 6512) ; Michoacin (Pringle 11964; Arséne 2868); Puebla (Purpus 
5554). 
De Candolle’s description was based upon one of Sessé and Mocifio’s plates. 
The description by the latter authors is much more ample, and when combined 
with the illustration leaves no doubt concerning the identity of the species. 
Erythrina petraea was based upon Purpus’s no. 2680, from Cerro de la Yerba, 
Puebla. Although the writer has not seen the type, the description applies to 
the present plant, and other specimens determined by Brandegee as E. petraea 
evidently belong here. Specimens collected by Purpus in 1908 at the type lo- 
cality of #. petraea are remarkable for their small leaflets. 
4, Erythrina setosa Mart. & Gal. Bull. Acad. Brux. 107: 194, 1843. 
TYPE LOCALITY: Regla, at 1,800 meters, and the eastern Cordillera of Oaxaca, 
at 2,100 meters. 
DISTRIBUTION: Oaxaca (Pringle 4687: Rose & Hough 4599: Conzatti & Gon- 
edlez 35; Conzatti 1422, 1507). 
Probably Erythrina horrida DC.’ is the same as FE. setosa, but the plate of 
Sessé and Mocifio,* upon which De Candolle’s description is based, 1s too poor for 
certain determination, Perhaps H#. horrida is, rather, the same as H. leptorhiza. 
De Candolle describes the calyx of the former as 5-dentate, and it is so illus- 
trated, but in view of the fact that the only calyces shown are the old ones in- 
vesting the stipe of the fruit, it is probable that their delineation is fictitious. 
5. Erythrina leptorhiza DC. Prodr, 2: 413. 1825. 
TYPE LOCALITY: Mexico, the description based on one of Sessé and Mocifio’s 
plates.° 
DISTRIBUTION : State of Mexico (Rose & Hay 5410, 5689; Pringle 6638, 5748; 
Rose é Painter 7831) ; Morelos (Pringle 6869) ; Hidalgo (Pringle 11965; Rose 
& Hay 5299); Puebla (Arséne 10089; Nicolas 128); Oaxaca (Conzatti 1790) ; 
Michoacfiin (Arséne 7220, 6818, 7367). 
Known in Michoacén as “ patol” and “ colorin negro.” 
Pringle’s no. 6638 was distributed as a new species.
