Herbarium, Leucena glauca was considered a native of Texas. In 
reality this species, which is now widely distributed through the 
warm parts of the world by cultivation, does not appear to have 
obtained a foothold in Texas, and probably grows spontaneously 
in the United States only on the island of Key West, where it 
is shrubby in habit. I have seen no flower or foliage of Leucena 
Greggii from Texas, and this tree is now admitted into The Silva of 
North America on the testimony of the late S. B. Buckley, who in 
1882 wrote to me that this tree, which he had previously collected 
on the Lampasas Mountains in Mexico, “is also quite common 
along Devil’s River of western Texas, also in the valley of the 
SILVA OF NORTH AMERICA. 
LEGUMINOS. 
San Saba River in San Saba County. On Devil’s River I saw it 
as a small tree in 1875. It grows singly or in groups, single trees 
not being uncommon. It grows in limestone soils of the cretaceous 
period in Texas. It ought to be cultivated in all the southern 
states. It would certainly be a valuable acquisition to the orna- 
mental trees of the south.” 
My description of the bark and of the wood of Leucena glauca 
(Silva N. Am. iii. 111) was drawn up from the wood specimen col- 
lected by Mr. S. B. Buckley on the San Saba River for the Jesup 
Collection of North American Woods in the American Museum of 
Natural History, New York.
