bose-paniculate terminating the stem and short branches from the upper 
leaves: involucral scales narrowly ovate-acuminate, appressed-hirsute: 
heads 12 mm high, 6-7 mm wide: corolla 5 mm long; tube pubescent; 
pales stramineous, acuminate, pubescent; akenes 5—6 mm long, 1 mm

Mexico: Collected on Ixtaecihuatl, Jan. 6, 1905. No. 1534. 
23. Encelia resinosa T. S. Brandegee, l. c., p. 240. 
Frutescent, stems striate, viscid: leaves oblong-ovate, 5—7 cm long, 
1—1,5 cm wide, acuminate, attenuate at base, sessile, entire, more or less 
viscid, pinnately veined, midnerve prominent and the numerous lateral 
veins obscure: heads 1,5 em wide without the rays, single terminating 
the leafy stems or with 2—3 additional ones from the axils of the upper 
leaves: scales of the involucre-linear-lanceolate, in 2—3 rows, very 
glutinous, 1 cm long, rays 2 cm long, bright yellow: chaff scarious with 
acuminate glutinous apex: corollas 7 mm long: akenes appressed silky- 
hairy, deeply notched between the two stout awns. 
Mexico: Collected in mountains near Ixmiquilpan, Hidalgo, August, 
1905. No. 1456. 
24. Gochnatia Purpusi T. S. Brandegee, l. c., p. 240. 
A shrub with tomentose branches, the young growth densely white- 
tomentose: leaves ovate or ovate-lanceolate, entire, sessile, 2,5 cm long. 
4—12 mm wide, white tomentose above becoming glabrate with age. 
densely white floculent-tomentose below: inflorescence in glomerules 3 cm 
in diameter terminating the branches: heads nearly sessile, 15 mm long, 
about 15-flowered: scales of the involuere in about 6 rows, floculent, 
pubescent, ovate-acuminate, extending down to base of the pedicel: 
flowers twice longer than the involucre, ochroleucous; lobes of the 
corolla revolute, half the length of the 5 mm long tube; style branches 
about 1 mm long, nearly truncate: akenes 3—4 mm long, sparingly silky- 
hirsute. 
This species differs from G. hypoleuca, in the arrangement of the 
inflorescence, its broader, nearly hemispherical, tomentose involucres, size 
and shape of the akenes. 
Mexico: Collected on rocky slopes of mountains near Tehuacan. 
Puebla, June, 1905. No. 1164. 
25. Pinaropappus spathulatus T. S. Brandegee, l. c., p. 241. 
Stems glabrous, weak, sparingly branched, several from a perennial 
root, leafy below, 10—15 cm high: leaves thin in texture, spatulate, acu- 
minate, entire or rarely slightly sinuate-dentate; blade 5—15 mm long, 
2 4 mm wide, attenuate into a more or less winged petiole 2 cm long: 
heads less than 1 cm long, inclined to be nodding; rays 6—7 mm long. 
In appearance this species is very different from P. roseus. The 
specimens are young and bear no mature fruit.
