lent aud resinous-viscid : leaves not in the least degree coriaceous ; 

 radical 6 or 8 inches long, lanceolate or linear-lanceolate, very 

 acute, salieutly and sharply serrate-toothed; the sessile cauline ones 

 more strongly toothed and the teeth spreading : heads only 3 to 5, 

 corymbose at summit of the stem: involucres broadly hemispherical, 

 1 to il inch broad ; bracts linear-lanceolate, acute, in about 3 not 

 very unequal series, herbaceous almost throughout except the inner- 

 most : rays 30 or more, showy. 



Near the Humboldt Wells, in eastern Nevada, 25th of .July, 

 1893. To be compared only with P. lanceolata, from which it dif- 

 fers most notably in the membranaceous texture of the whole plant 

 as well as in the fine close glandular indument. 



Aster militaris. 



Rigidly erect, 1 to 1] feet high, equably leafy aud simple up to 

 the somewhat fastigiately corymbose panicle: leaves 2 or 3 inches 

 long, scabrous-puberulent on both faces, and with scabrous-ciliolate 

 margins, mid vein prominent, lateral nerves none, the upper cauline 

 lanceolate, very acute, mucronate by the excurrent strong midvein, 

 tapering to a narrow half- clasping base, entire or obscurely serrate- 

 toothed: involucre turbinate, the oblong-linear obtuse bracts numer- 

 ous and much imbricated, green- herbaceous along the midvein and 

 at tip, pubescent, appressed ; rays numerous, pale- purplish: achenes 

 sparsely pubescent: pappus not copious, rather fragile. 



A well-marked species of genuine Aster, but not intimately related 

 to any other known. Obtained at Grant's Pass, in southern 

 Oregon, September, 1892, by Mr. Howell. 



Aster amplissimus. 



Erect, rather slender, 1 to 2 feet high, simple up to the summit, 

 then parting into 3 or more peduneuliform short branches, each 

 bearing a single very large head; stem red, bearing more or less 

 white hirsutulous pubescence, this often running somewhat in lines, 

 or on one side only, except under the heads, when it is denser: leaves 

 all ample, thin, entire; the radical 8 to 12 inches long, oblanceolate, 

 tapering to a slender winged and ciliolated petiole; cauliue few and 

 remote, from somewhat spatulate-lanceolate to linear- lanceolate, 

 acutish, sessile by an auriculate-clasping base : heads ■] inch high, 

 more than 1 inch broad; bracts from oblong- to linear-lanceolate, 

 acute, in 2 series but subequal, the outer series quite herbaceous, not
