Fraxinus greggii Gray
Gregg's ash, Littleleaf ash, Escobilla
USDA Symbol: frgr2
USDA Native Status: Native to U.S.
Gregg’s ash has nearly evergreen leaves that are less than 2 in. long. It is a shrub or sometimes small tree to 19 ft. in height. Smooth, thin, gray bark; slender branches; and pinnate, dark-green, leathery leaves characterize the plant. Flowers are inconspicuous.
The specific epithet, “greggii,” was given for Josiah Gregg, (1806-1850). He was born in Overton County, Tennessee. In the summer of 1841 and again in the winter of 1841-42 he traveled through Texas, up the Red River valley, and later from Galveston to Austin and by way of Nacogdoches to Arkansas. He took note of Texas geology, trees, prevalent attitudes, and politics. At the same time, Gregg began compiling his travel notes into a readable manuscript. His “Commerce of the Prairies”, which came out in two volumes in 1844, was an immediate success. In 1848 he joined a botanical expedition to western Mexico and California, during which he corresponded with and sent specimens to the eminent botanist George Engelmann in St. Louis. Subsequently, the American Botanical Society added the Latinized form of his name, “greggii” in his honor, to twenty-three species of plants. Gregg died on February 25, 1850, as a result of a fall from his horse.
