long naked or subnaked, hirsute-hispid peduncles, 1 to 1.5 cm. high, 
including the rays 3 to 4 cm. in diameter: involucre 2-3-seriate ; bracts 
of the involucre subequal, linear-oblong, obtuse or obtusish, a little 
shorter than the flowers of the disk, externally hirsute-pubescent: ray- 
flowers about 12, neutral; rays conspicuous, yellow, 1 to 1.5 cm. long, 
4 to 6 mm. broad: disk-flowers numerous; pappus reduced to two in- 
conspicuous knobs: achenes glabrous. —Mexico. Territory of Tepic: 
in the Sierra Madre, between Santa Gertrudés and Santa Teresa, 8 
August, 1897, Dr. J. NV. Rose, no. 3378 (hb. Gr. & hb. U.S. Nat. Mus.). 
A species belonging to the § Pterophyton, and most nearly related to 
V. capitaneja, Nees. 
Eryngiophyllum, n. gen. of Composite (Coreopsidee). Heads 
heterogamous, radiate. Involucre campanulate; bracts 2—3-seriate, free _ 
or very slightly united at the base. Receptacle flat or somewhat con- 
vex, paleaceous; pales thin, membranous. -flowers uniseriate, 
fertile ; achenes subtriangular. Disk-flowers regular ; corolla-tube short, 
gradually ampliate above into an elongated-campanulate 5-toothed limb; 
achenes densely compressed. Anthers obtuse at the base, appendaged 
at the apex. Style-branches hirtellous-elongate-appendaged ; stigmatic- 
lines short. Pappus obsolete. Herbaceous perennials with radical 
leaves and cymose inflorescence. 
E. Rosei. Leaves densely rosulate from the crown of a deep peren- 
nial root, often somewhat falcate, linear-lanceolate, 3 to 12 cm. long, 
5 to 8 mm. wide, undivided or bearing one or more arcuate-ascending 
lateral divisions, mucronate-acute, entire, somewhat cartilaginous-mar- 
gined, ciliate, glabrous on both surfaces, more or less areolate: inflores- 
cence axillary scapoid compound bracteate cymes, exceeding the leaves: 
heads about 1 cm. high, 2.5 cm. broad, on glabrous or slightly hirtellous 
peduncles 2 to 8 cm. ong: involucre 2-3-seriate ; bracts of the involucre 
subequal ; those of the two outer series subherbaceous, lanceolate, acute, 
ciliate, much thickened and gibbous at the base: ray-flowers about 20, 
rays yellow, conspicuously nerved: disk-flowers numerous: pappus 
quite obsolete or represented by very short protuberances : apical appen- 
_ dages of the anthers short, broad, obtuse: achenes glabrous. — Mexico. 
State of Sinaloa; between Rosario and Calomas, 12 July, 1897, Dr. J. 
WV. Rose, no. 1618 (hb. Gr., and hb. U. S. Nat. Mus.). 
The natural affinity of the genus here proposed is apparently with 
Isostigma and Chrysanthellum. In the technical characters of the head, 
particularly the style-branches, it approaches more closely the latter 
genus.
