Pentstemon divergens n. sp. 



Section Speciosi ; anlhers horseshoe-shaped, with rather 

 narrow cells, splitting to the partition but not through, 

 smooth; plants apparently belonging close to P. cristatus, but 

 anthers different and flowers red; roots thick and woody; 

 stems tufted, simple, erect, very leafy below with mostly 

 short internodes, 1-2 feet high, the interrupted and leafy and 

 compact spike often over half the whole; leaves ashy-rough- 

 pubescent, 2-4 inches long, the lower lanceolate on short 

 petioles and 1 inch wide, the stem leaves mostly sessile and 

 ovate-lanceolate with cordate base, and those subtending the 

 iiora! clusters ovate and about 1 inch long, the upper ones 

 shorter, all leaves acute ; flowers many in dense clusters ; 

 peduncles and pedicels almost none ; calyx large, ovate ; sepals 

 oblong-ovate, acute, nerved, green, 3-4 lines long, mostly 

 Avith acuminate tips; whole inflorescence shortly glandular- 

 hairy; corolla 1 inch long, rather abruptly widened 2 lines 

 above the base and ventricose, the lobes very broad and short, 

 slightly bilabiate, the lower lobes reflexed; throat 4 lines 

 wide; sterile filament densely short-bearded; dried flowers 

 rather-purplish-red. This certainly lies close to P. miser and 

 the latter is much nearer to P. pumilus than the classification 

 of Gray would seem to indicate. Bishop, Owen's Vallev, Cal- 

 ifornia, 5000 feet altitude, May 15, 1897. 

 Pentstemon puberulus n. sp. 



This belongs to the P. heterodoxus section and resembles 

 it; casepitose, simple stems erect, 1 foot high; root leaves 

 many, spatulate to oblong-spatulate, obtuse, on slender peti- 

 oles 1-2 inches long; lower stem leaves similar but longer and 

 narrower, often 4 inches long, acutish; upper stem leaves 

 narrowly oblong, sessile, not auricled, 1-2 inches long; all 

 leaves puberulent, but not glandular; thyrsus narrow, inter- 

 rupted, leafy-bracted below, very shortly glandular-hairy 

 even to the corolla ; flowers clustered at the nodes ; peduncles 

 and pedicels slender but mostly shorter than the calyx ; calyx 

 iy2 lines long, with lobes lanceolate and having purplish but 

 scarcely hyaline margins ; corolla deep-purple, tubular funnel- 

 form, 1 inch long, gradually widened from base to tip, where 

 tt is 2-5 lines wide, scarcely bilabiate, the lobes sliort and 

 rounded and little spreading and the lower ones the longer, 

 corolla arched. Summit, Owen's Valley, California, 7000 feet 

 altitude. Mav 22, 1897.
