Distribution of Southern Plants, Nos. 4523, 4524), by Rugel at Saint 
Mark’s, by Faxon and Sargent, in 1886, on the banks of the Miami 
River, and by Chapman and Mohr near Appalachicola. In Texas 
it was collected in 1894 near Kerrville, Kerr County, by Mr. A. A.

the desert region of southern Nevada, and on the Tulare Plains 
of California, where it grows in moist soil near springs and streams,

who was born and educated at Weingarten in Baden, came to the 
United States in 1840 and devoted several years to collecting plants 
in the southern states and in Cuba for the English botanist Robert
