onl.y constant character by which 0. occidentalis may be distinguished, 

 it i)Ossesses still other characters which, though variable, still point 

 towards a specific segregation. These include the taller and coarser 

 habit, the stouter rays of the involucre, which are usually but not 

 always nearly equal, and the larger flowers and fruit. The leaflets 

 are 9 to 13 in number, while in 0. Fendleri they are usually 5 to 9, 

 but occa.sionally 11 or even 13 leaflets occur (e.g., Hermits Peak, New 

 Mexico, F. H. Snow). In all of these characters, and especially in 

 the uniformly present involucel, the Sierran specimens ally themselves 

 with the Oregonian species. This is also in accord with our present 

 views as to the origin of the Sierran flora. The following specimens 

 have been seen from California : 



Chilnualna Creek, Mariposa County, August, 1895 and October, 1896, 

 Congdoii ; Kuntz Place, Mariposa County, August 11, 1899, Congdon ; base of 

 Clouds Rest, August 5, 1898, Congdon; Peregoy Meadows, just south of Yosemite 

 Valley, in the Canadian Zone at 2225 m. alt., Hall, no. 9676 (leaflets lanceolate, 

 5 to 15 mm. wide); Natural Bridge of Volcano Creek, Basin of the Upper 

 Kern River, Hall and Babcocl-, no. 5443 (leaflets ovate, 12 to 25 mm. wide); 

 Giant Forest, Tulare County, August, 1905, Mrs. Katharine Brandegee, Herb 

 Univ. Calif, no. 173212 (leaflets broadly lanceolate to ovate, 20 to 40 mm. wide); 

 same locality, date, and collector. Herb. Univ. Calif, no. 173214 (leaflets elliptic 

 to nearly orbicular, 30 to 55 mm. wide). 



Pentstemon Bridgesii X heterophyllus hyb. nov. 



Herbage glabrous except in the inflorescence, which is glandular as 

 in P. Bridgesii: inflorescence compound, the pedicels erect; flowers 

 either erect or ascending, never horizontal : sepals lanceolate, acute, 

 glandular : corolla rose-pink, the color sometimes dominated by yellow, 

 sometimes by orange-color, about 15 mm. long, funnelform with no 

 distinction between tube and throat, bilabiate ; lower lip 5-8 mm. long, 

 of 3 narrowly oblong obtuse spreading lobes; upper lip erect, 2-lobed 

 at summit : anthers sagittate, the cells dehiscent across the confluent 

 apex, scabrous on the edges of the orifice ; pollen grains sterile, flat 

 and angular: sterile filament glabrous. 



Vicinity of Nellie, a stage station on Palomar Mountain, San Diego 

 County, Mrs. A. R. Valentien, July 15, 1910. 



This form resembles P. Bridgesii in the foliage, pubescence, branch- 

 ing of the inflorescence, and sepals, but the flowers stand erect or 

 nearly so, as in P. heterophijllus, which species it also resembles in 

 the flaring corolla. In shape of corolla, however, the new form is 

 intermediate between th(» two species mentioned and tlie flowers are 

 smaller tlinn in either of them. The color is decidedly toned down from
