BOTANY, 
Erigeron stenophyllum (sp. nov.) : humile, csespitosum, pube appressa termiter cinereum; 
caulibus floriferis simplicibus e cauclice perenni inferne foliosissimis apice nudo rnonocepbalis ; 
foliis angustissime linearibus integerrimis ; capitulo magno; ligulis (semipollicaribus et ultra) 
circiter 40 albis uniseri'atis involucro pubescente multo longioribus ; acheniis hirsutissimis; pap- 
po simplici. On bill-sides and steep banks of the Pecos ; October. Stems six to ten inches 
high, growing in dense tufts. Leaves one to three inches long, about a line wide, many of 
them almost filiform ; the lower ones tapering to the base, which is not ciliate nor hirsute; all 
merely cinereous with a very fine and close strigose pubescence. Scales of the involucre all 
nearly equal and similar, scarcely biserial, linear-lanceolate, acuminate, three or four lines 
long, somewhat tomentose-pubescent. Rays linear, broad for the genus, apparently pure white 
or slightly tinged with purple, certainly not ochroleucous. Achenia flat, two-nerved, densely 
hirsute with long and white hairs. Pappus similar in the ray and disk, composed of a single 
series of scabrous capillary bristles of about the length of the disk-corolla, not fragile nor 
caducous, of equal length, and not accompanied by short setae or squamelhe. This most re¬ 
sembles E. ochroleueum, Nutt. ; but the leaves are hoary with a finer pubescence, and are not 
hirsute towards the base; the heads are longer and more showy, the rays not ochroleucous, the 
achenia remarkably villous-hirsute, and the exterior pappus wanting.
