﻿64 PLANTS FENDLERIAN.E. 



que calloso-apiculatis ; capitulis corymboso-paniculatis parvulis pedicellis nudis sublongiori- 

 bus ; involucri circ. 30-flori squamis puberulis omnibus appressis obtusis ; acheniis glaber- 

 rimis. — Foot of mountains on the sunny side, along the creek, eleven miles above Santa 

 Fe ; July. (347.) — Plant much smaller in all its parts than the preceding. Stem a foot 

 or so in height. Leaves H 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. (Buleostylis) Californica, Ton. &• 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.! 



*" * Brickellia (Bulbostylis) Wislizeni (sp. nov.): glanduloso-hirta ; caulibus seu ramis elongatis sim- 

 pliciusculis foliosis ; foliis oppositis internodiis longioribus ovato-oblongis e basi subcordata arete sessilibus 

 argute serratis aculis lucidis undique hirtello-scabris triplincrviis subtus grosse reticulatis ; ramulis floridis bre- 

 vibus monocepbalis in racemum laxum foliosum dispositis; involucri circ. 20-flori squamis pauciusculis 2- 3- 

 seriatis laxis omnibus lanceolatis sensim acuminatissimis, intimis attenualis glabris pappum crebre serrulatum 

 subsequantibus, exterioribus £ brevioribus glanduloso-birtis ; 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. 



t There is a well-marked, undescribed Stevia in Coulter's Mexican collection, apparently resembling S. 

 dissitifolia and S. podocephala, DC, which may be thus characterized : — 



Stevia .trichopoda (Harv. fy Gray,ined.) : herbacea, glanduloso-pubescens ; caulibus gracilibus erectis ; 

 foliis oppositis longe dissitis (inferio'ribus desunt) ovalibus utrinque obtusis crenatis hispido-scabris triplinerviis 

 venosis ; cyma nuda effusa ; capitulis longe pedicellatis sparsis ; corollis involucri squamis aculis glandulosis 

 duplo longioribus, tubo purpurea, limbo pallida irregulari subpalmato (an semper ?) ; acheniis glabriusculis ; 

 pappo paleaceo brevj et 3-aristato, aristis corollam adaequantibus basi submarginatis. — The leaves of the spe- 

 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
