midrib beneath, provided with a row of submarginal glands on either 
half of the blade, more or less revolute-margined: peduncles slender, 
filiform, 4 cm. or less in length: heads small, about 6 mm. high: invo- 
lucre 4 mm. high, glabrous ; bracts of the involucre 8, linear, blunt, 
obtusely keeled: ray-flowers 8; pappus of 2 slender setae and a small 
intermediate anterior scale; rays including the tubular portion 4 mm. 
long: disk-flowers about 15; pappus of numerous slender unequal setae: 
mature achenes of both ray- and disk-flowers about 2.5 mm. in length, 
puberulent. — Mexico. State of Sinaloa: Lodiego, 9 to 15 October, 
1891, Dr. Edward Palmer, no. 1605 (hb. Gr., and hb. U. S. Nat. Mus). 
In a natural sequence this species is to be placed near P. papposd, — 
Gray, and P. Palmeri, Watson. From the former it is readily and 
easily separated by having the heads disposed on long slender peduncles 
instead of subfastigiate; from the latter it differs in the smaller fewer- 
flowered heads, shorter involucre and more slender peduncles. P. 
puberula differs from both P. papposa and P. Palmeri, in having the 
stem and branches puberulent. 
Protis siNALOENsIs, Fernald, var. lancifolia, n. var. Leaves 
sessile, lanceolate, 2.5 cm. or less long, 6 mm, or less broad, usually 
hirtellous-puberulent on the upper surface and on the midrib beneath, 
bearing 1 to 6 pairs of setae toward the base: peduncles 11 cm. or less 
in length: rays golden-yellow or before expansion slightly copper-colored 
externally, somewhat larger than in the type of the species. —ie |
