shorter lobes to the leaves and their teeth are broadly ovate, ab- 
ruptly acuminate, instead of lanceolate. The general habit is per- 
haps more like G. caespitosum James, but in that species the lower 
part of the stem is grayish-pubescent with short reflexed hairs. 
G. Pattersonii is a subalpine plant growing at an altitude of 2500- .

This is nearest related to G. viscosissimum, but the corolla is 
lighter in color and the pubescence is different, being decidedly 
teflexed, Strigose, not at all glandular, except on the inflorescence.
