: obtuse-icaved forms with lanceolate sepals. 



, glaber var. Wardi (Gray Proc. Am. Acad. 12 

 82 as species). This is only a rough-pubescent form. 

 It occurs from the Sierras at Summit and Susan ville, Califor- 

 nia, to eastern Utah, mostly in dry regions and low elevations 

 and differs from P. Fremonti only in the larger corolla, an- 

 thers split only two-thirds of the way up, and in the broader 



Pentstemon glaber var. Fremjonti (T. & G. Pros. Am. 

 Acad. 6 60 as species). 



Pentstemon confertus var. attenuatus (Douglas Bot. Reg.

The corollas of Pentstemon deustus are remarkably de- 



Pentstemon eriantherus Pursh was published in 1814, its 

 synonym P. cristatus Nuttall was a nomen nudum in 1813 in 

 Fraser's catalogue and was not published until 1818 in Nut- 

 tali's Genera, it can not therefore supersede the earlier name 

 of Pursh, which was also a nonem nudum of Nuttall m Fra- 

 ser's catalogue. It should also be noted that Pursh's reference 

 fo the name of Nuttall is an error. 



Pentstemon eriantherus var. argillosus n. var. 



Flowers 8-12 lines long, about 4 lines wide, often only 

 twice the calyx lobes; sterile filament not exserted, slightly 

 long-bearded at top ; corolla regularly funnel-form, upper 

 side not arched ; calyx sparsely and shortly villous ; thyrsus 

 elongated and whorls distant. John Day Valley, Oregon, 

 June 6. 1902, Cusick, No. 2803. This differs from the type 

 which has the calyx long-villous, fllowers 6 lines wide at tip 

 and arched, with exserted and very villous sterile filament and 

 condensed thyrsus, flowers over 1 inch long. 



Pentstemon Clebumi n. sp. 



This is between P. eriantherus and Jamesii ; plants rarely 

 over 1 foot high, rough-pubescent on the leaves and shortly 

 and sparsely villous on the inflorescence and obscurely if at all 

 viscid: stem leaves in well developed plants Hnear-spatulate 

 or broadly linear, always entire, mostiv surpassing the dense 

 and leafy thyrsus which begins near 'the root; root leaves 

 tufted, oblanceolatc to oval, rarelv obscurely dentate, long- 

 petioled and petioles broad and 2-4 inches long; calyx nearly 

 sessrie even in fruit and clusters very dense; calyx lobes 

 mostly ovate with a short acumination, oGcasionally lanceo-
