148 BOTANICAL GAZETTE [AUGUST 
Machaeranthera rhizomata, n. sp.—Perennial from such a run- 
ning rootstock as is often seen in Solidago and Aster, with numerous 
slender roots: stem strict and simple, very leafy, 3-5 dm. high, 
minutely glandular with some scattered moniliform hairs: leaves 
quite entire, oblong-lanceolate to broadly linear, up to 3 cm. long, 
rather densely scabrous: heads few to several, in a short compact 
corymb with foliar bracts, scabrous-glandular especially on the 
involucres; involucral bracts linear-lanceolate with long dark- 
colored slender reflexed or refracted acuminations: rays linear: 
pappus sordid. 
The rootstock, the entire leaves (the bristly tipped teeth wanting), the 
strict stem, and the compact terminal corymb readily distinguish this species. 
The type is C. L. Shear 3461, West Cliff, Colorado, August 13, 1896, and in the 
National Herbarium bears accession no. 835200. 
Machaeranthera inops, n. sp——A depauperate perennial, from 
a tap root, with few to several short widely divaricate or ascending 
stems from its crown: stems slender, simple or branched, 5—12 cm. 
long, densely canescent, as are also the leaves: leaves small, from 
obovate to spatulate-lanceolate, some of them crenately toothed 
around the summit: heads few, medium size; involucral bracts 
linear-oblong, subacute, minutely pubescent, obscurely or not at all 
glandular, some of the fips refracted: rays wanting: pappus 
fuscous. 
The type sheet is no. 417219 in the National Herbarium, collected by 
F. A. Walpole on Glacier Mountain, Oregon, in the Crater Lake region, August
