WYETHIA SCABRA, Hook. in Lond. Jour. Bot. 6, p. 247: foliis linearibus seu lineari-lanceo- 
latis acutatis (inferioribus sæpe oppositis) integerrimis sessilibus venoso-trinervibus utrinque 
cum caule stricto gracili ultrapedali hispidulo-scaberrimis ; capitulo solitario nudo ; involucro 
hemispheerico disco breviore, squamis pluriseriatim imbricatis appressis coriaceis oblongis, ex- 
terioribus appendice foliosa lineari patente auctis, interioribus pungenti-mucronatis acheniis 
glaberrimis compresso-quadrangulatis pappo brevissimo calvculiformi irregulariter dentato 
coronatis. Sand bluffs, near Inscription Rock, on the Puerco of the West, New Mexico. A 
remarkable species, of which only fruiting specimens were gathered. The stems are over a 
foot long, and do not show the base; possibly they are only branches, but they are perfectly 
simple. These, like the leaves, (which are 4 to 6 inches long, and 3 to 7 lines wide,) are very 
rough with short and close papillose bristles, much as in Helianthus Maximiliani. The short 
and sparing veins are confluent into a false nerve within the margin on each side, making the 
leaf appear three-nerved. Head short-peduncled, an inch in diameter. Rays not seen. Disk- 
corollas slender, glabrous. Achenia about 4 lines long, the angles very acute. This species 
completes the parallel between Wyethia and Balsamorhiza, having the involucre imbricated as 
in Balsamorhiza Hookeri, &c., while several species of the latter genus are now known with the 
entirely foliaceous involucres of Wyethia helenioides, augustifolia, &c. Without doubt, the 
plant described above is the same as that of Geyer. 
BALSAMORHIZA MACROPHYLLA, Nutt. l. c.; var. pube minuta molli canescens ; foliis plerisque 
elongatis (radicalibus subpedalibus) circumscriptione lanceolatis 1-2-pinnatipartitis, segmentis 
sepe dentatis incisisve; involucri squamis exterioribus magnis foliaceis elongato-oblongis seu 
سے سی‎ quandoque dentatis. Hill-sides, near Sonoma, California; May. All the species cf 
group are extremely variable in foliage. I possess only a leaf of Nuttall's B. macrophylla,
