leaves. The trees were so large that it was impossible to climb them in 
order to get specimens, but some of the racemes were found upon the ground 
and leaf specimens were secured from young plants. Dr. Calderén’s speci- 
mens from Comasagua are sterile, but recently he was so fortunate as to find 
ample fruiting material on the hills near Santa Tecla, whose flora is similar 
to that of the Sierra de Apaneca. Dr. Calderén has forwarded a photograph 
of the tree from which the fruits came, eivdently a gigantic one, which he 
states was larger than a ceiba, sufficient indication of its size to those who are 
acquainted with Central American trees. The seeds were found upon the 
ground, where they were beginning to germinate, their cotyledons at that time 
being of a deep but brilliant green. 
This tree is well known in Salvador, under the vernacular name of cashal. 
It is said to be an important lumber tree. 
Amerimnon cuscatlanicum Standl., sp. nov. 
Tree, the branchlets and leaves glabrous; stipules oblong-ovate, 10-12 
mm. long, obtuse, soon deciduous; leaves somewhat blackened in drying, 
the petioles and rachis slender, 20-25 cm. long, the petiolules slender, 2.5—4 
mim. long; leaflets 13-17, lance-oblong or the lowest ovate, 6-10 cm. long and 
2-2.5 em. wide, the lower ones smaller, slightly narrowed to the obtuse apex, 
rounded to subacute at base, thin, bright green above, the venation promi- 
nently reticulate, much paler beneath, the venation prominent and finely 
reticulate; racemes numerous, forming a dense panicle about 8 cm. long on 
old wood, the bracts similar to the stipules, ciliate, the branches densely 
brown-pilosulous, the bractlets minute, oblong, densely pilosulous; flowers 
white, about 16 mm. long; calyx 4-5 mm. long, densely brown-pilosulous, the 
lobes about equaling the tube, oblong-ovate, obtuse, the carinal lobe much 
longer and narrower than the others; petals glabrous, the standard short- 
clawed, the blade suborbicular, 12 mm. long, rounded at base, obscurely 
retuse at apex, the wings obovate, oblique, rounded at apex, nearly 10 mm. 
long. 
Type in the U. S. National Herbarium, no. 1,152,618, collected at San 
Salvador, Salvador, in 1923, by Dr. Salvador Calderén (no. 1557). Sterile 
specimens which probably represent the same species were collected at 
Comasagua in December, 1922, by Dr. Calderén (no. 1555). 
The Salvadorean tree is related to Amerimnon lineatum (Pittier) Standl.® 
and A. retusum (Hemsl.) Standl.,” of Costa Rica and Panama, but differs 
from both in its perfectly glabrous leaflets, which are also more numerous 
and narrower. The vernacular name is funera. The wood is highly valued 
for cabinet work and for general construction purposes. 
Amerimnon lineatum, described from the Nicoya Peninsula of Costa Rica, 
also has been collected at San Salvador, where it bears the name of funera. 
Dr. Calderén states that the trees of A. cuscatlanicum are leafless during the 
dry season, but that in the middle of March the young leaves and flowers 
are produced, the flowers, however, lasting only two or three days. The 
stipules are conspicuous upon the very young branches, but quickly fall.
