Discussion
Teucrium defressum is the smallest species of the genus within the limits of the United States ; its nearest ally is T. laciniatum. Most of its organs are only one-half as large as those of its relative. The pubescence is coarser and more scabrous. Wright's number 1545, Coll. N. Mex., 1851-52, and Thurber's number 193 from El Paso, Texas, collected in April, 185 1, both belong here.
