PEUCEPHYLLUM, Nov. Gen. Eupatoriacearum. 
Capitulum pluri-(10-16)-florum. ‘Involucrum circiter 12-phyllum, disco brevius, laxum ; 
phyllis vix biseriatis lineari-subulatis, inferne carinato-concavis margine tenuiter scariosis, 
superne foliiformibus. Receptaculum planum nudum. Corolle longe cylindric, fauce non 
ampliatee, 5—dentatae, dentibus ovatis patentibus. Styli rami lineares, plano-convexi, obtusissimi,

prorsus minutim glandulosi. Аслеша haud matura subturbinata, teretia, hirsutissima. Pappus | 
eapillaris, setis rigidulis pluriserialibus valde inaequalibus denticulatis, longioribus corollam 
subaequantibus. Fruticulus ramosus, glanduloso-viscidulus; ramis monocephalis usque ad 
apicem foliosis; foliis acerosis punctatis alternis; floribus lutescentibus. 
PEvcEPHYLLUM ScHorTI.—Diluvial banks of the Colorado, in Sonora; February ; Schott. 
Stems a span high, loosely branched. Leaves crowded, ar inch or less in length, filiform, | 
obtuse, glabrous, but glandular when young and more ог less glutinous, strongly glandular- 
punctate. Head cylindraceous, half an inch long. Scales of the involucre obscurely one-nerved, 
the alternate and exterior ones rather smaller than the others. Corolla glandular at the summit. 
I know of no published genus to which this manifestly Eupatoriaceous plant is particularly 
allied. The name alludes to the acerose, fir-like foliage. 
BRICKELLIA OLIGANTHES, Gray, Pl. Wright, 1, p. 84, & 2, p. 71. Santa Cruz, Sonora; Wright, 
— Thurber. 
BRICKELLIA VERONICAEFOLIA, Gray, l. с. Sonora; Schott; the habitat not recorded. This is an 
abundant species in Northern Mexico. It is distributed under eight different numbers in Ber- 
landier's collection. 
BnICKELLIA LacINIATA, Gray, Pl. Wright,1, p. 81. Bachimba; Thurber. Organ mountains ; 
Bigelow. On the Rio Grande; Parry. Dr. Schultz, in Seemann's Botany of the Herald, p. 
301, has applied to this species the name of B. dentata, Schultz, mss., supposing it to be De Can- 
dolle's Clavigera dentata, having overlooked my statement, in РЇ. Wright, 1, p. 83, that the 
plant of De Candolle is B. Riddellii, and that the present species was not deseribed in De Can- ` 
dolle's Prodomus. It is 1365 and 1783 of Berlandier's collection. 
.— BRICKELLIA SIMPLEX, Gray, Pl. Wright, 2 p. 13. Babocomori to Santa Cruz, Sonora. At 
Bufotillo Ranch, Dr. Bigelow gathered specimens of a Brickellia with the foliage of B. simplex, ES 
and with a similar involucre, but the heads are small and more numerous. |
