 well-marked and sliowj species, though not displaying such an ample panicle of flowers as do 

 the Californian ones from Thurher and Mr. Wallace, evidently belong to the same species. It 

 pertains to the section Cepocosmus. 



Pentstemon Fendleei, Gray, in Bot. Pope's Rep. p. 12, t. 5. Common apparently, from the 



Platte through Kew Mexico and the Eocl^y mountains to Chihuahua^ {Wislizenus^ No. 245^) and 



brought by all the collectors. It is Fendler's No, 576, and Wright's 1473. (This clearly is 



not distinct from P. cyananthus, Hook. Bat, 3Iag,y f. 4464, which was overlooked when 



P. Fendleri was characterized ; it must accordingly bear that name.)

y cultivated P. barbatus, as well as fuller-flowered ; the virgate panicle becoming 2 or 5 

 feet in length, and bearing a long succession of fine scarlet blossoms, in some plants of the 

 most brilliant hue. The calyx-segments are either marginless or slightly margined. The 

 lower lip of the corolla at the throat is bearded, either somewhat copiously or sparingly, or in 

 some plants the beard wholly disappears, so that the name harhatits is not characteristic of this 

 species. But that all our forms are specifically identical with the old Chelone barbata I cannot 

 doubt. In establishing his P. Torreyi, Mr. Bentham, who is generally so very accurate, has 

 made two mistakes ; the first, into which he was naturally led by the imperfection of the 

 original specimens, was in referring his plant to the section Cepocosmus, and comparing it with 

 P. imberbis, whereas it is a genuine Elmigera, having the upper lip erect, concave, and 

 moderately two-lobed, the lower 3-parted and reflexed ; the second in attributing to P. barbatus 

 a bearded sterile filament, whereas it has always been described as with a nated one, con- 

 formably to the distinction formerly taken in this respect between Chelone and Pentstemon.

 the Botanical Magazine does feeble justice to the very deep and carmine corolla, and represents 

 the plant as coarser and the leaves as considerably larger than usual. The latter in the wild 

 specimens are only |— 1 inch long, and very thick and firm. Far from being ^^ annual?'' the 

 plant is shrubby. The upper lip of the corolla is erect or at length somewhat recurved; the
