Pentstemon glaucifolius (sp. nov.): glaberrimus, glaucus; caule confertim folioso basi 
ramoso (1-2 pedali;) foliis crassiusculis integerrimis acutatissimis lanceolatis oblongisve in 
petiolem brevem attenuatis, cieteris semi-amplexicaulibus plerumque cordato-ovatis vel e basi 
sub-cordata ovato-lanceolatis ; panicula virgata multiflora ; pedunculis folia floralia superan¬ 
tibus folioso-bibracteatis 1-3-floris; calycis segmentis ovatis subacuminatis; corolla azurea 
sesquipolicari sursum ampliata ; filamento sterili apice dilatato hirtello. 
Fort Reading, on the Sacramento river, California. Cauline leaves 1-1^ inches long, about 
| inch wide at the clasping base, tapering to the acute apex ; the floral similar, gradually 
decreasing in size ; bractlets also foliaceous. Anthers hispid-ciliate, also hirsute at the inser¬ 
tion. Calyx nearly as in the broader-sepalled form of P. heterophyllus. A most elegant and 
showy species, which I should have referred to Bentham’s P. azureus from his character, except 
that the sterile filament is not glabrous, and in my specimen of Hartweg’s, No. 1819, the leaves 
are all rather narrowly lanceolate : indeed I cannot distinguish that plant from P. heterophyllus. 
It is possible that Mr. Bentham had the two plants, and drew the characters of the foliage from 
our present plant, and of the sterile filament from the allied P. heterophyllus. If the sparing 
beard of the sterile filament cannot be relied upon, and the two run together, then the variable 
species well deserves the name of heterophyllus. 
Pentstemon gracilentus (sp. nov.): glaber; caule tenero subpedali adscendente; foliis 
integerrimis inferioribus oblongo-lanceolatis in petiolum longiusculum attenuatis, superioribus 
paucis augusto-linearibus sessilibus, floralibus lineari-setaceis ; panicula laxa subsimplici; cymis 
pedunculatis 3-5-floris; calycibus pedicellisque requelongis pubero-glandulosis, segmentis 
oblongo-lanceolatis breviter acuminatis ; corolla tubuloso-infundibuliformi subbilabiata coerulea 
staminibusque glaberrimis ; filamento sterili filiformi superne obsoletissimi barbato. 
At the base of Lassen’s butte, N. California. Lower leaves about two inches long, and 
with a petiole about one inch long ; the upper few, and gradually reduced to slender bracts ; 
corolla slender, half an inch long ; anthers intermediate in structure between those of the 
sections Eupentstemon and Saccanthera, glabrous, except a minute denticulate ciliation at the 
line of dehiscence. 
Pentstemon Newberryi (sp. nov.): fruticosus, glaber, cEespitoso-procumbens; foliis ovali- 
bus seu ovato-oblongis sub-coriaceis crebre serrulatis, caulinis obtusis basi in petiolum contractis 
summis sessilibus acutis; racemo 7-11-floro ; calycis segmentis lanceolatis sensim acuminatis 
pedicellum asquantibus; corolla punicea tubulosa belabiata, labio, inferiore patente trifido intus 
lineis 2 barbato; staminibus sub-exsertis; antheris (praesertim ad margines) lanatis ; filamento 
sterili brevi filiformi longitudinaliter parce barbato. (Plate XIY.) On rocks, forming broad 
tufts near Mount St. Joseph’s, N. California. A well marked species of the section Elmigera, 
but with woolly anthers. Leaves turning blackish in drying. Corolla deep crimson, very 
handsome, 1^ inches long.
