the corolla, evidently are of this species. Dr. Brewer notes that the 

 tube of the calyx is rose-colored, while the lobes are green. According 

 to Dr. Kellogg, not only the calyx-tube, but also the peduncles, are 

 bright purple. According to Dr. Brewer, the corolla is dotted with 

 brown spots, the upper lip light yellowish. 



Pentstemon Palmeri (inter P. Jamesii et Cobceam) : sesquipeda- 

 lis ; foliis lanceolato-ligulatis argute denticulatis cauleque glaucescenti- 

 bus, superioribus semiamplexicaulibus, inferioribus spathulatis in 

 petiolum attenuatis ; panicula nuda racemiformi virgata laxiflora 

 glanduloso-puberula ; bracteis minimis ; pedunculis 2 - 3-floris ; pedi- 

 cellis gracilibus ; sepalis ovatis glabriusculis ; corolla pollicari pallide 

 purpurea supra calycem latissime campanulato-ampliata, ore hiante, 

 labio inferiore intus hirsuto ; filamento sterili leviter exserto apice 

 incurvo insigniter flavo-barbato. — Arizona, in Skull Valley, and on 

 Rio Verde, near Fort Whipple, Drs. Elliott Coues and Edward 

 Palmer. A well-marked species, with sterile filament bearded in the 

 manner of P. cristatus, and corolla even more dilated in proportion 

 than that of P. Cobcea. 



Pentstemon Bridgesii (Saccanthera) : prseter inflorescentiam 

 glaber ; caule erecto 1 - 2-pedali ; foliis integerrimis spathulato-lan- 

 ceolatis linearibusque, caulinis sessilibus ; panicula virgata racemosa, 

 pedunculis 2 - 5-floris ; sepalis ovato-oblongis acuminatis cum pedicellis 

 asquilongis viscoso-pubentibus ; corolla coccinea (pollicari) cylindraceo- 

 tubulosa sursum leviter ampliata, fauce nuda, labio superiore erecto 

 apice bilobo, inferiore tripartito, lobis recurvis oblongis tubo 2 - 3-plo 

 brevioribus ; filamento sterili nudo apice complanato ; antheris quasi 

 sagittatis apice solum dehiscentibus (rima hirtello-denticulata), loculis 

 deorsum maxime productis diu parallelis. — No. 218 in Californian 

 collection of the late Thomas Bridges. Yosemite Valley, very scarce, 

 Bolander. A handsome and very interesting new species, having the 

 anthers most distinctly of the section Saccanthera, but the habit and 

 corolla of the section Elmigera. In cultivation it would rival P. 

 barbatus and its allies.* 



* To the Chelonece there is apparently to be added a new genus, namely, 

 BEEENDTIA, nov. gen. Chelonearum post Leucocarpum. 



Calyx tubuloso-campanulatus, subangulatus, fere ajqualiter 5-dentatus. Corolla 

 infundibuliformis, bilabiata, labiis patentibus subaequalibus, superiore bilobo, in- 

 feriore trilobo, lobis brevibus rotundatis. Stamina 4, didynama, absque rudimento
