revolute; often a fascicle of small leaves in the axils represent- 
ing the suppressed branches: heads mostly solitary at the ends 
of the peduncle-like branches, the main axis usually with 3; the 
peduncles naked or bracteate: involucre canescent, about 1°™ 
broad, its bracts in two series: rays 8-12, oblong to elliptic: disk 
corollas tubular, noticeably dilated just above the very short 
glandular pubescent tube: pappus wholly wanting. 
Notwithstanding the morphological similarity of the floral characters of 
this and G. mu/tifiora Benth. & Hook., the distinctness of the two can scarcely 
be questioned. In the excellent revision of the genus by Robinson and Green- 
man (Proc. Bost. Soc. Nat. Hist. 29: 87-104. 1899) mention is made of narrow- 
leaved forms of G. multiflora which occur to the southwest of the range of 
the species, but judging from the specimens cited nothing like the plant now 
described was at hand. In any case, the species now proposed is strongly 
marked by its slender, rhizome-like roots, its very narrow revolute leaves, 
and its slender fascicled stems; in contrast with the woody taproot, the rela- 
tively stout branched stems, the lanceolate leaves, and the somewhat larger 
heads and broader rays of G. mu(tiflora. 
The type is no. 968, Leslie N. Goodding, Meadow Valley Wash, southern 
Nevada, May 17, 1902; in blossom and with mature akenes; growing among 
the rocks on dry steep mountain slopes. 
v Encelia virginensis, n. sp.— Perennial, the base shrubby and 
freely branched, 3-5 %™ high including the herbaceous part of the 
plant: the ligneous stems white, rather slender; the herbaceous 
branches leafy below, terminating in a long slender monocepha- 
lous peduncle, light green, roughish-puberulent as are also the 
ligneous stems for a time: leaves opposite below but alternate 
upward, short-petioled, broadly rhomboid- or deltoid-ovate, rarely 
sub-cordate, generally 3-nerved from the base, 12-20™" long, 
some nearly as broad: the pubescence of two kinds, some short 
white strigose-hispid hairs, and a fine close puberulence: pedun- 
cles 1-2 long, naked or 1- or 2-bracted near the head: invo- 
lucre strigose-canescent; its bracts acute, in about 2 series, 
linear-lanceolate, rather coriaceous, some of them abruptly nar- 
rowed to a slender somewhat recurved tip: rays 12-20, minutely 
pubescent below, cuneate-oblong, deeply 3- or 4-toothed at the 
truncate apex, neutral, 15—20™" long: disk-flowers numerous ; 
the tube proper narrow, half as long as the cylindrical throat: 
style branches acute, linear: akene flattened, broadly linear-spatu-
