GerarpIA Wrienutu, Gray (Bot. Bound. Survey, p. 118)—Stems 
simple, from a perennial root, virgate, very scabrous, as well as the linear- 
filiform, sharply mucronate leaves; peduncles as long as the flowers; calyx 
truncate, with 5. short teeth; corolla yellow, broadly campanulate from a 
very short tube, pubescent on the outside, very smooth within; filaments 
short, only villose at the apex; anthers similar, naked, very obtuse, sagittate 
at base; cells subulate-awned; stigma clavate —Sanoita Valley, Arizona, at 
5,500 feet elevation, August, 1874, Rothrock (643). The specimen agrees 
in every respect with the original description, except that the stem is not 
simple, but branched. It is probably like our Eastern G. purpurea, which 
has stems of both kinds. The flowers in the dried state have a yellowish 
and not a purple tinge.
