MEMOIRS OF THE NEW VORK BOTANICAL GARDEN. 345 



calyx about i cm. long, villous-viscid, divided almost to the base ; 

 lobes linear-lanceolate, acuminate; corolla about 2 cm. long, reddish, 

 puberulent, obliquely funnelform, gibbous on the lower side near the 

 throat ; limb over 15 mm. wide ; lower lip inside and the sterile stamen 

 bearded with long yellow hairs which are club-shaped and curved at 

 the apex. 



In the general habit and the size and form of the flower this suggests 

 P. Jamesii and P. cn'status, but is apparently not related very closely 

 to either. It is easily distinguished by the saliently toothed leaves. 

 In the western part of the state, at a low altitude.
