collected by Dr. Woodhouse in Sitgreave's expedition. Stems 1 to 2 feet high, simple, virgate. 

 Leaves 1 to 3 inches longj 1| to 3 lines wide, thickish. Pedicels ahnost always simple and 

 ebracteolate, 3-8 lines long. Calj^x 2-3 lines long; corolla; much as in the last; sterile 

 filament shorter^ and gradually very slightly dilated upwards. This is evidently most related 

 to P* lanceolatus, Benth.; hut is more downy, with simpler iuflorescence ; and the much larger 

 and more dilated corolla is of a different color ; being red in P. lanceolatus, according to Dr. 

 Gregg's notes on a specimen gathered by him at Buena Vista.

 tains ; BigeloiVj WrigJit^ (1476 ;) also gathered by i)r. Woodhouse. A pretty species, which has 



+ 



been raised in the Cambridge Botanic Garden, from Mr. Wright's seeds. It is a foot or 18 inches 



high, including the virgate inflorescence of half that length.

and 1^ to 3 lines wide, usually tapering to both ends. Corolla two-thirds of an inch long. 



Anther-cells soon divaricate. According to Bentham's arrangement this belongs to the section 



Eupentstemon. 



Pentstemon PtwicEUS (sp. nov.) : glaberrimus, glaucus ; caule herbaceo valido ; foliis crassis, 



radicalibus obovatis, caulinis ovatis cordato-araplexicaulibus plus minusve connatis acutis 

 integerrimis; floralibus parvis ; panicula contracta virgata nuda interrupta ; cymis subsessilibus 

 multifloris ; pedicellis gracilibus (flore fere aBquilongis) nudis ; sepalis ovalis obtusis ; coroUa 

 infundibuliformi, limbo fere ^qualiter 5-lobOj lobis rotundatis patentibus ; antheris glabris, 

 filamento sterili sub apice hinc barbato. — In the Guadalupe canon^ Sonora, June, 1851 ; Tliurher 

 (& Captain E. K. Smith. This is apparently a large, and must be a strikingly handsome species, 

 with its glaucous foliage and *^ brilliant scarlet" flowers. Lower leaves (with the base of the 

 stem) wanting in my specimen ; but those present show a tendency to be connate-perfoliate. 

 Corolla less than an inch long ; the throat moderately enlarged ; lobes about 3 lines long. 



Pentstemon puniceus, var,? Pareti: foliis superioribus (caet. ignoti<) lanceolatis basi cordato- 

 amplexicaulibus ; cymis pedunculatis ; floribus paullo minoribus ; sepalis oblongis ; filamento 

 sterili sub apice hinc densissime barbato. — On the Eio Gila^ March, 1852 ; Parry. The specimens 

 gathered are merely two flowering summits ; the color of the blossoms not recorded, nor posi- 

 tively to be made out. But its floral characters so nearly accord with the preceding that it 

 must, for the present at least, be appended to it. 



Pentstemon Wrightii, Hooh. Bat. Mag.y t. 4601. On rocty mountain sides near the head of 

 the Limpio, June ; Wright^ (unnumbered.) Santa Cruz mountains and LosKogales ; Captain E, 

 K, Smith. (The latter a somewhat remarkable form, but clearly of this species.) We have 

 also had this pretty species in cultivation. The corolla is rich rose-color, as described in the 

 letter-press, but with none of the deep red given in the figure in the Botanical Ma 



Pentstemon spectabilis {Thurher^ MSS.; Torr. & Gray^ in Bot. Whipp. Facif. Railroad
