BOTANY. 113 
collected by Dr. Woodhouse in Sitgreave’s expedition. Stems 1 to 2 feet high, simple, virgate. 
Leaves 1 to 3 inches long, 14 to 3 lines wide, thickish.  Pedicels almost always simple and 
ebracteolate, 3-8 lines long. Calyx 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.; but is more downy, with simpler inflorescence ; 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 Хич. 
PENTSTEMON VIRGATUS, (sp. nov.): glaber, seu minutissi dul berulus; caule herbaceo 
simplici s stricto; foliis lineari-lanceolatis acutis саса, тараш еме РАМ Ын 
obtusis, ручай gradatim in bracteas subulatas breves diminutis ; panicula virgata elongata 
multiflora subsecunda ; pedunculis plerumque oppositis 1—4-floris pedicellisque sapissime 
floribus haud longioribus ; sepalis ovato-rotundis margine subscariosis ; corolla (roseo-lilacina 
venis intus purpureis) dilatato-infundibuliformi bilabiata, labiis æquilongis, superiore vix con- 
cavo bilobo, inferiore patente tripartito, lobis omnibus ovalibus conformibus ; antheris glabris 
subexsertis ; filamento sterili glaberrimo apice dilatato.—Santa Rita del Cobre, on the moun- 
tains ; Bigelow, Wright, (1476 ;) also gathered by Dr. 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. Leaves from 1} to 4 inches long, 
and 11 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 PUNICEUS (sp. nov.): glaberrimus, glaucus; caule herbaceo valido ; foliis crassis, 
radicalibus obovatis, caulinis ovatis cordato-amplexicaulibus plus minusve connatis acutis 
integerrimis, floralibus parvis ; panicula contracta virgata nuda interrupta ; cymis subsessilibus 
multifloris; pedicellis gracilibus (flore fere zquilongis) nudis; sepalis ovalis obtusis; corolla 
infundibuliformi, limbo fere equaliter 5-lobo, lobis rotundatis patentibus; antheris glabris, 
filamento sterili sub apice hinc barbato.—In the Guadalupe сайоп, Sonora, June, 1851; Thurber 
& 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.? PARRYI: foliis superioribus (caet. ignotis) lanceolatis basi cordato- 
amplexicaulibus ; cymis pedunculatis; floribus paullo minoribus; sepalis oblongis; filamento 
sterili sub apice hinc densissime barbato.—On the Rio 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 
ust, for the present at least, be appended to it. 
Pentstemon Wricutu, Hook. Bot. Mag., t. 4601. Оп rocky mountain sides near the head of 
the Limpio, June; Wright, (unnumbered.) Santa Cruz mountains and Los Nogales ; Captain E. 
K. Smith. (The latter à 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 Magazine.
