equal, widely spreading : stamens included in the tube of the 

 corolla, the sterile filament pilose for the upper third ; anther cells 

 dehiscent the whole length and explanate : style about equal to 

 the stamens, slightly exceeding the calyx lobes.

The original specimens of Pentstemon Gairdneri were collected 

 in the Blue Mts., Oregon, by Douglas, and the species is well 

 represented by Cusick's no. 1637, from that region. The variety 

 is the commoner form in central Washington and is readily dis- 

 tinguished by its larger corolla with spreading limb and larger 

 calyx lobes. Intergrading forms are not rare. 



- Pentstemon confertus globosus var. nov. 



Erect, 2-3 dm. high, perfectly glabrous throughout, pale green : 

 radical leaves oblong, acute, entire, 6-10 cm. long, attenuate into 

 a petiole 1-2 cm. long ; cauline leaves 3 or 4 pairs, the lower 

 pair usually short-petioled, the others sessile, all similar to the 

 radical but becoming broader upwards, the uppermost commonly 

 ovate : inflorescence a dense head-like panicle of many short-ped- 

 icelled flowers, rarely with a second verticillate cluster below : 

 calyx lobes nearly distinct, ovate-acuminate, narrowly scarious- 

 margined, entire or obscurely dentate, nearly one half as long as 

 the corolla : corolla intense blue, nearly 2 cm. long, tubular, 

 bilabiate, the lower lip sparsely villous within, the lobes rounded, 

 entire, subequal, one fourth as long as the tube : stamens included, 

 the sterile bearded above the middle : anthers splitting their entire 

 length but not explanate, the cleft ciliate margined, 



Wallowa Mts., northeastern Oregon, altitude 6000-7000 ft.,

Strikingly different from P. confertus Dougl. or any of the 

 numerous forms of var. coeruleo -purpureas Gray, but lacking any 

 distinct morphological characters. Except for the perfectly gla- 

 brous inflorescence, it would be referred rather to P. attenuatus 

 Dougl., its flowers being fully as large as in that plant. 



'Pentstemon Newberryi rupicola var. nov. 



A much-branched densely caespitose decumbent shrub, 5—8 

 cm. high, pilose-puberulent below, the inflorescence glandular- 

 viscid : leaves numerous, opposite, ovate or orbicular, more or less 

 dentate, obtuse, glaucous, with a persistent bloom, thick, not turn-
