STANDLEY—TROPICAL AMERICAN PHANEROGAMS, 175 
the plant under the generic name Amorpha, but without a specific designation. 
In this later work the locality for the plant is given as “In agris Cordovae et 
in Praedio S. Josephi.” 
Of the specimens at hand those which agree best with the plate and descrip- 
tion were collected at Acaponeta, Tepic, April, 1910, by J. N. Rose, P. G. Rus- 
sell, and P. C, Standley (no. 14474). The fruit of these specimens agrees 
almost exactly with that figured. The leaflets, however, are less numerous, 
broader, and rounded rather than acute at the apex. It is not improbable 
that the Tepic specimens represent an additional new species, but it is unsafe 
to describe them as such until some plant agreeing better with the original 
illustration is collected. The tracings of Sessé and Mocifio’s plates are so 
obviously imperfect that no confidence can be placed in the characters they 
seem to indicate. The writer is unable to determine the location of the locali- 
ties mentioned by Sessé and Mocifio. If the well-known Cérdoba in Veracruz 
is the one referred to, it is probable that the typical plant is still unknown in 
herbaria. 
The specimens obtained by Doctor Rose and the writer were taken from a 
handsome tree about 6 meters high. The fruit is borne in the greatest pro- 
fusion. It is about 2 cm. long and 1.3 cm. wide, with the upper suture straight 
or concave, and bordered by a thin wing about 1 mm. wide. 
8. Ateleia insularis Standl., sp. nov. 
Branchlets strigillose-puberulent, with numerous conspicuous pale lenticels; 
leaf rachis 15 to 24 em. long; leaflets about 18, ovate or very obliquely oblong- 
ovate, 4 to 6.5 cm. long, 2.2 to 3 cm. wide, broadly rounded and very oblique 
at the base, obtuse at the apex, subcoriaceous, with prominulous, finely reticu- 
late venation, in age nearly glabrous except for a few minute appressed hairs 
along the veins; racemes 6 to 12 cm. long, rather densely flowered, the flowers 
short-pedicellate; calyx truncate, strigillose-puberulent, 2.5 mm. long; fruit 2.2 
to 3 cm. long, 1.5 to 2 em, wide, glabrous, the upper suture convex, furnished 
with a thin wing 2 to 3 mm. wide; seed turgid, about 7 mm. long and 4 mm. 
wide, dark reddish brown. 
Type in the U. S. National Herbarium, no, 345929, collected on Maria Madre 
Island, off the Pacific coast of Mexico, May, 1897, by E. W. Nelson (no. 4186). 
Also obtained at the same locality, May 7, 1897, by F. S. Maltby (no. 73). 
Closely related to the Tepic plant discussed above, but sufficiently different 
in the form of the fruit and leaflets to deserve specific rank. Although only a 
small amount of Mexican material is available for study, examination of an 
extensive series of specimens of the Cuban Ateleia cubensis Griseb. indicates 
that the form of the fruit is very constant. 
THE MEXICAN AND CENTRAL AMERICAN SPECIES OF ERYTHRINA. 
The North American species of Erythrina have never been mono- 
graphed, and no attempt has ever been made to correlate the large 
number of published names. Many of the species are known only 
from very imperfect descriptions or from equally unsatisfactory 
illustrations, and the difficulty of any attempt to formulate a satis- 
factory account of the genus is increased by the incompleteness of 
most herbarium specimens. The plants seldom bear flowers and 
fruit at the same time, and since they often flower when devoid of 
leaves it is difficult to assemble complete material that is certainly
