There appear to be no differences in the number of the scales. With age, 
the scales seem to grow laterally, the spinules increasing in number to 19 or 
more. 
BOTANY.—Ten new species of trees from Salvador. Pau C. 
STANDLEY, U. S. National Museum. 
The ten species of trees here described all occur in the Republic of 
Salvador, but some of them extend also to other parts of Central 
America. Part are based upon specimens obtained by the writer 
during the winter of 1921-22, and others upon material collected by 
Dr. Salvador Calder6n of the Salvadorean Department of Agriculture. 
One of the three described is of some importance locally as a source of 
lumber, while another represents a genus not reported previously from - 
North America. 
~ 
Pseudolmedia mollis Standl., sp. nov. 
Large tree, the young branchlets densely fulvous-pilose; petioles very 
thick, 4 to 6 mm. long; leaf blades oblong or narrowly ovate-oblong, 11 to 16 
em. long, 4 to 6.5 em. wide, somewhat abruptly acuminate, obliquely rounded 
at base, subcoriaceous, glabrate above except along the nerves, the venation 
depressed, beneath paler, copiously soft-pilose, especially along the costa and 
lateral nerves, the venation elevated, the lateral nerves about 15 pairs, arcu- 
ately ascending, anastomosing near the margin; fruit globose-oval, 2 em. 
long, densely soft-pilose, subtended at base by few broadly ovate, acutish 
bracts. 
Type in the U.S. National Herbarium, no. 1,152,341, collected at Comasa- 
gua, Salvador, December, 1922, by Dr. Salvador Calderén (no. 1382). 
The leaves resemble in shape and texture those of P. oryphyllaria Donn. 
Smith, the only other species of the genus known to occur in Central America, 
but the pubescence is altogether different in the two species. The vernacular 
name of the Salvadorean tree is ‘‘tepeujushte.”’ 
Ledenbergia macrantha Standl., sp. nov. 
Tree, about 6 m. high, with long, somewhat pendent branches; young 
branchlets sparsely tomentulose, soon glabrate; petioles slender, 2 to 4.5 em. 
long, sparsely villosulous; leaf blades elliptic or broadly ovate, 4.5 to 8 em. 
long, 2.5 to 4.5 em. wide, acuminate, acute or obtuse at base, thin, glabrous 
above, beneath villosulous along the costa near the base, elsewhere glabrous 
racemes very numerous and forming a dense panicle, their rachises 12 to 20 
cm. long, tomentulose; pedicels filiform, 5 to 10 mm. long; sepals oblong- 
oblanceolate, in fruit 8 to 13 mm. long, 3 to 4.5 mm. wide, glabrate, con- 
spicuously veined; fruit glabrate, rugulose, 3 mm. long. 
Type in the U. 8. National Herbarium, no. 1,111,202, collected along 
roadside at Puerta de la Laguna, near San Salvador, Salvador, February 24, 
1923, by Dr. Salvador Calder6n (no. 680). The following additional speci- 
mens have been seen:
