148 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
Gard. Herb.); probably at San Antonio, 1878, Ball 1697 (Mo. 
Bot. Gard. Herb.). 
The glabrous pods and the auriculate cauline leaves serve at 
once to separate this species from all other species of Lesquerella 
except L. grandiflora, and from that species it is most easily dis- 
tinguished by its hirsute stems and smaller flowers. The basal 
leaves in L. auriculata, from the specimens at hand, seem never 
to become so deeply pinnatifid as in L. grandiflora. Ball's speci- 
men labelled "probably at San Antonio" may well be from 
farther north and east since it has not been confirmed by other 
collections from this locality.

Rather coarse annual or biennial, loosely stellate, pubescent 
with few-rayed stellae; stems at the base sparsely villous, erect 
or decumbent, 2-8 dm. long, simple or sparingly branched; 
terminal bud developing a fertile stem; radical leaves 3-10 cm. 
long, oblanceolate or oblong, variously pinnatifid, sometimes 
merely dentate, often pinnate with equal segments, acute or 
obtuse, narrowed to a sparingly villous petiole; cauline leaves 
lanceolate to oblong, conspicuously toothed, 1-3 cm. long, 
sessile and auriculate at the base; flowers yellow, large; petals 
often 1 em. long, broad; filaments gradually dilated at the base; 
fruiting inflorescence elongated, open; pedicels divergent-ascend- 
ing, often curved, 1-1.5 em. long; pods erect, very shortly stipi- 
tate, nearly sedili, glabrous, globose or slightly longer than 
broad, 4-6 mm. in diameter; styles 1-1.5 mm. (rarely 2 mm.)
