64 PLANTH FENDLERIANZ. 
que calloso-apiculatis ; capitulis corymboso-paniculatis parvulis pedicellis nudis sublongiori- 
bus ; involucri cire. 30-flori squamis puberulis omnibus appressis obtusis ; acheniis glaber- 
rimis. — Foot of mountains on the sunny side, along the creek, eleven miles above Santa 
Fé; July. (847.) — Plant much smaller in all its parts than the preceding. Stem a foot 
or so in height. Leaves 12 inch long, coarsely and sharply toothed, scarcely acuminate, 
glabrous, but minutely resinous-dotted. Heads more paniculate, barely one fourth of an 
inch long, with few if any loose bractlets at the base, and these conformed to the proper 
involucral scales, ovate, and obtuse or slightly acute. Achenia 5-angled with five inter- 
mediate nerves, which are sometimes inconspicuous. 
308. B. (Busosryiis) Carirornica, Torr. § Gray, Fl. 2. p. 79: var. foliis pleris- 
que subcordatis. — Rocky hill-side on the Mora River, and eight miles eastward, in bot- 
tom land; Aug. (346.)— The cauline leaves are mostly cordate, and with rather longer 
petioles than in the Californian specimens collected by Douglas; but the plant of Hart- 
weg’s recent collection is wholly intermediate. Mr. Bentham (in Bot. Voy. Sulph.) has 
very properly carried out the intimation given in the Flora of North America, and annexed 
Bulbostylis to Brickellia. The pappus is so strongly barbellate-denticulate in some spe- 
cies (as in the original B. cordifolia and especially in B. cylindracea, Gray § Engelm., 
from ‘Texas, and an undescribed Mexican species found by Dr. Wislizenus*) that Clavi- 
gera is separated by a merely arbitrary character,+ 
-* Brickettia (BuLzostyiis) Wistizent (sp. nov.) : glanduloso-hirta ; caulibus seu ramis elongatis sim- 
pliciusculis foliosis ; foliis oppositis internodiis longioribus ovato-oblongis e basi subcordata arcte sessilibus 
argute serratis acutis lucidis undique hirtello-scabris triplinerviis subtus grosse reticulatis ; ramulis floridis bre- 
vibus monocephalis in racemum lJaxum foliosum dispositis ; involueri circ. 20-flori squamis pauciusculis 2—3- 
seriatis laxis omnibus lanceolatis sensim acuminatissimis, intimis attenuatis glabris pappum crebre serrulatum 
subsequantibus, exterioribus } brevioribus glanduloso-hirtis ; acheniis sericeis. — Mountains around Cosiquiria- 
chi, west of Chihuahua, Dr. Wislizenus. — Herbaceous stems, or branches, 18 inches high. Leaves thin, an 
inch and a half in length, the coarsely reticulated veins very prominent underneath. Heads over half an inch 
in length ; the pappus white and copious. Corolla ochroleucous. 
+ There is a well-marked, undescribed Stevia in Coulter’s Mexican collection, 
dissitifolia and S. podocephala, DC., which may be thus characterized : — 
Srevia tricnoropa (Harv. & Gray, ined.) : herbacea, glanduloso-pubescens ; caulibus gracilibus erectis ; 
foliis oppositis longe dissitis (inferioribus desunt) ovalibus utrinque obtusis crenatis hispido-scabris triplinerviis 
venosis ; cyma nuda effusa; capitulis longe pedicellatis Sparsis ; corollis involucri squamis acutis glandulosis 
duplo longioribus, tubo purpurea, limbo pallida irregulari subpalmato (an semper?) ; acheniis glabriusculis ; 
pappo paleaceo brevi et 3-aristato, aristis corollam adzequantibus basi submar 
cimen are an inch, the internodes 3 to 4 inches, in length ; the cyme several times dichotomous, with’Slender, 
diffusely spreading branches, dividing into monocephalous peduncles half an inch or an inch long. The awns 
of the pappus, as in some other species, are somewhat scarious-dilated towards the base. This dilatation is so 
apparently resembling 8.
