Hedeoma sancta has heretofore been confused with the very 
rare H. Drummondit. In this connection it is interesting to 
note that there are only three specimens of the latter species in 
the Columbia University Herbarium, two of these are the 
Drummond specimens, and the third is Wright’s number 463. 
The species just described differs in the more robust habit, in 
the larger broader and almost flat leaf-blades which conspic- 
uonsly surpass the calyx and corolla. The species is founded 
on the following specimens : 
Texas: San Antonio, April, 1853, Dr. Geo. Thurber; 
San Diego, 1885-86, Mss Mary B. Croft. 
'TEUCRIUM DEPRESSUM. 
Apparently biennial, minutely pubescent with spreading 
hairs. Stems branched at the base; branches spreading or 
decumbent, 3-12 cm. long, leafy throughout, usually simple: 
leaves clicraate: blades palmately 3-parted or sometimes 
5-parted, 5-10 mm. long, sessile; segments entire or some, 
especially the middle one, toothed or incised: racemes nar- 
row, spike-like, 1-6 cm. long: bracts similar to the leaves 
and only slightly smaller: pedicels 1-2 mm. long, stout: 
calices 3-4 mm. long ; segments lanceolate, acuminate, longer 
than the tube, finel pubescent, with minute rigid tips, 
I-ribbed, reticulated: nutlets fully 2 mm. high, coarsely 
wrinkled. 
In dry soil, southern Texas. Spring. 
Teucrium depressum is the smallest species of the genus 
within the limits of the United States; its nearest ally is 7. 
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, 1851, both belong here.
