 obovate-spatulate, tapering to broad connate-clasping petioles ; 

 upper cauline perfoliate, oblong to ovate, 1-1.5 dm. long, 4-6 cm. 

 wide, irregularly and sharply denticulate, glaucous and glabrous : 

 panicle narrow, interrupted, the short peduncles 2-3-flowered, i 

 or 2 pedicels more than twice as long as the remaining one, from 

 3-15 mm, : sepals ovate, acute, 5 mm, long, membranously mar- 

 gined, glandular, wrinkled, overlapping : corolla rose-colored, 4 cm. 

 long, the tube slightly curved, i cm. long, 5 mm. broad at base, the 

 throat 15 mm. broad; upper lip 15 mm. long, with lobes 7 mm, 

 wide, 5 mm. deep ; lower lip with 3 rounded, spreading bearded 

 lobes : sterile filament conspicuously exserted, hooked at the apex 

 and densely bearded with long, yellow hairs ; fertile stamens in-

Collected in IXL Cafion, Churchill County, Nevada, June 15, 



1902, by Otto F, Heizer. It is closely related to P, Palinen 



Gray, differing in the more contracted infloresence, smaller calyx, 



larger corolla, with tube more than twice as long as the calyx, 



the anthers without the ciliate edges on the expanded cells. 



^Pentstemon Grinnellii sp. nov.

 broad petioles half as long as the blades, middle and upper sub- 

 sessile, uppermost connate-clasping ; lower leaves smaller than the 

 upper stem-leaves, ovate-oblong or orbicular, sharply dentate, 

 1-5— 4 cm. long, 1—2 cm. wide ; upper ovate-acuminate, cuneate or 

 cordate at base, about 8 cm. long, 2-3 cm. wide : panicle pyra- 

 midal, loose and open ; peduncles 2-3-flowered the lateral pedicels

 veins evident, closely longitudinally parallel : corolla cream-col- 

 ored diffused with pink, the proper tube shorter than the calyx,
