from its mouth. 
Srituineta Licustrina, Michauz. 
A-bushy and much branched shrub, 3 to 6 feet in height ; 
leaves thin, entire, lanceolate, and tapering at each end. I do 
not think it has been observed by others than myself westward 
of Georgia. Found by me in eastern Texas, near the residence 
of Dr. Veatch, about forty miles west of the Sabine River. 
Uutmus crasstronia, Nuttall. 
This tree has not yet found its way into any general work 
upon American plants. Described by Mr. Nuttall in the Trans- 
actions of the American Philosophical Society, Philadelphia. 
Leaves crowded, scarce an inch in length, 5 lines in width; ob- 
long, ovate, obtuse, serrate, somewhat pubescent beneath, sca- 
brous, unequal base, thick. Flowering in July. I notice this tree, 
because Mr. Nuttall did not find it in flower, and was therefore 
unable to complete the description. Found on the Red River 
prairies in the vicinity of Fort Towson ; from thence westward 
to the Cross Timbers, about thirty five miles beyond the mouth 
of the False Washita, the last large tributary of the Red River 
from the north. The Cross Timbers are said by the hunters to 
be a line of timbers extending from the Red River to the Mis- 
souri. I have also seen it in Texas skirting a small prairie two 
miles from the Sabine, near the road from Natchitoches, La., to 
Nagadoches, Texas. 
The usual and proper time of flowering is undoubtedly in July. 
I however found it in flower in Texas in September. Itisa 
tree of middle size, and affording an abundance of shade. ‘Trunk 
1 to 14 feet in diameter ; commences branching 6 or 8 feet from 
the ground; branches very intricate and thick. In the Red River 
prairies it is generally found on the summits of swells or eleva- 
tions, in clumps of from four to ten, giving an agreeable variety 
to the otherwise monotonous prairie. It would be useful and 
ornamental asashade tree. In other American species of Ul- 
mus the inflorescence appears early in the spring, (in the southern 
states in February,) and precedes the foliage. In this the foliage 
appears the last of April or the first of May, and the flowers in 
July. wits
