1916] NELSON & MACBRIDE—WESTERN PLANTS 149 
involucral bracts in 3 unequal series, linear-acuminate, with delicate 
membranous ciliolose margins: ray flowers few (1-4 or wanting), 
ligule oblong, 6-8 mm. long; disk flowers slender, tube longer than 
the slightly dilated throat: linear-acuminate anthers and stigmas 
well exserted: achenes brownish, softly pubescent becoming 
glabrate. 
The material seen by the writers consists of two fine sheets collected by 
F. V. Coville and Elmer I. Applegate, under nos. 544 and 545, August 16, 1897 
in Pinus Murrayana forest, on the headwaters of the Deschutes River, Crook 
County, Oregon. These are the type sheets and bear accession nos. 380795 
and 380796 in the National Herbarium. 
Macronema_ glomerata, n. sp.—lLow _ undershrub, freely 
branched, whitened throughout with short dense woolly pubes- 
cence, 2-3 dm. high: leaves linear, 2-4 cm. long, 1-2 mm. broad, 
callous-tipped: heads few (4-10), crowded at the summit of-the 
stems, 10-14 mm. high; involucral bracts unequal, resembling the 
leaves into which they pass: rays conspicuous, 2-5, linear-oblong; 
disk flowers about twice as many as the rays, their slender tubes 
longer than the fusiform throat: fuscous pappus about as long as 
the corollas: achenes silky, less than half as long as the pappus. 
The splendid sheet of this species, accession no. 401293 in National Her- 
barium, is named as the type. It is F. A. Walpole 370, secured at Ashland, 
Oregon, September 12, 1899. 
Macronema Walpoliana, n. sp.—An undershrub but probably 
taller than the preceding, the stems simple up to the narrow thyr- 
soid panicle of numerous heads, glabrate or with a minute lanate 
pubescence persisting in the inflorescence: leaves linear, sub- 
cuspidate, glabrate and subglutinous, 2-4cm. long: involucre 
turbinate, its bracts scarious, sublanate or ciliate, in 2 or 3 series; 
number of flowers as in the last: rays with conspicuous oblong- 
linear ligules 10-14 mm. long: achenes brownish, sparsely pubes- 
cent, a little shorter than the copious fuscous pappus. 
Distributed under Aplopappus without specific determination. From 
Klamath County, Oregon, F. A. Walpole 387 and 406, collected September 19 
and 27, respectively, 1899. These two sheets bear accession nos. 401312 and 
401334 in the National Herbarium, the latter being designated as the type. 
Macronema scoparia, n. sp.—A profusely and _ fasciculately 
branched undershrub; the old stems with a grayish-brown shreddy
