NEW OR NOTEWORTHY SPECIES.—XXIX. 319 
subracemose from the middle, leaves oblong or obovate- 
oblong, 1 or 2 inches long, tapering to a petiole, obtuse, 
entire, rather firm in texture, glabrous, sparsely punc- 
tate, inflorescence glandular-puberulent: racemes of from 
3 to 5 large flowers: sepals large, obovate, cuspidately 
acute, the margins scarious and lacerate-toothed: corolla red- 
purple, more than an inch long, with subcylindric tube and 
throat and not very strongly bilabiate limb, its lobes obovate- 
oblong: sterile filament hirtellous at and near the summit. 
At 11,500 feet in the mountains about Pagosa Peak, 
southern Colorado, 6 Aug., 1899, C. F. Baker. 
^ ERIGERON sETULOSUS. Near E. pumilus and no larger but 
more pronouncedly multicipitous, with well developed and 
subligneous branched caudex, the branches notably leafy 
up to within an inch of the solitary head: leaves narrowly 
spatulate-lanceolate and canescent throughout, like the stem 
and peduneles, with short spreading stiff bristly hairs: 
bracts of the involucre sparingly setose-hispid; rays pur- 
plish or white: outer pappus conspicuous, of broadly linear 
and well elongated pales incisely toothed at summit. 
Obtained at Aztec, New Mexico, 28 April, 1899, by C. F. 
Baker, and inadvertently referred by me, in Baker's distri- 
bution, to E. concinnus, from which it is now seen to be most 
distinct, being much more like E. pumilus as to size, and 
the monocephalous character of the’ branches, while by its 
distinet subligneous caudex it is equally remote from both 
these its allies. 
/ERr0GoNUM ARCUATUM. Near E. flavum, about as large, 
more extensively cxspitose, forming broad matted tufts: 
leaves oval, obtuse, an inch long or less, abruptly tapering 
to a rather slender petiole about as long, white-tomentose
