mostly entire. The calyx is not equally 4-cleft, but is equally 2-cleft and the divisions 2-cleft， 
nearly as in C. purpurea, from which it differs by the short lower lip of the corolla.

CASTILLEJA INTEGRA (sp. nov.): perennis; caule stricto tomentoso ; foliis linearibus integerrimis 
subtus tomentulosis, floralibus oblongis obovatisque integerrimis coloratis (paniceis); spica con- 
ferta; calyce æqualiter vel postice profundius bifido, lobis bifidis lanceolatis obtusiusculis labium

(undistributed,) Bigelow. Guadaloupe cañon, Sonora; Capt. E. K. Smith. Also gathered in 
the Rocky Mountains further north by Mr. Kreuzfeldt, in Gunnison's expedition. Stem one or 
two feet high, mostly simple, rigid ; leaves 14 to 3 inches long, 2 to 3 lines wide, entire ; most 
of the floral ones almost wholly petaloid, ample, shorter than the fully developed flowers. 
Calyx 8 or 12 lines long, red or reddish ; “corolla reddish green ;" galea 6 to 8 lines long; 
the lower lip very short Apparently a well marked new species of the section Callichroma. 
Itis No. 584 of Fendler's New Mexican collection; and Dr. Digelow gathered specimens in 
Whipple’s expedition on the Llano Estacado.

in the same State; Captain E. K. Smith. A slender, often branching plant, with an annual or 
biennial root. Flowers, especially the corolla, very much smaller than in the typical Californian 
plant (such as Hartweg's No. 1896 ;) but Hartweg's No. 1897 connects the two. The lobes of 
the calyx vary from nearly entire to deeply 2-cleft; the tube is often split down deeper on the 
posterior than the anterior side. 
CASTILLEJA LAXA (sp. nov.): herbacea, Ra caulibus e radice perenni subdiffusis 
ramosis is gracilibus ; foliis tenuibus scabridis lineari-lanceolatis integerrimis basi haud dilatatis, 
floralibus calyce brevioribus, superioribus rubro-coloratis ; floribus paucis confertis breviter pedi- 
cellatis ; calyce rubello antice profundius postice leviter fisso, dentibus brevibiis obtusis ; corollae 
galea magna, lobis labii inferioris brevissimis obtusis.—Mountain sides near Santa Cruz, Sonora ; 
Wright, (1490.) This appears to be a well-marked species of the section Hemichroma, with 
the bracts and calyx more colored than is usual in that section. The thin leaves do not turn 
blackish in drying; they are mostly about 2 inches long and 3 lines wide; the floral shorter and 
blunter, the lower mostly green, the upper colored red. Calyx very thin, slightly pubescent, an 
inch long, exceeding the lower lip of the corolla by 3 or 4 lines, but half or two-thirds of an 
inch shorter than the ample galea, nearly straight, deeply cleft anteriorly, but on the posterior 
side only to the depth of 2 or 3 lines; the teeth broad and short. Galea somewhat pubescent 
on the back, yellowish, the edges tinged with red.
