Henderson: New Plants from the Northwest 347 



No. 3013. Dry, stony ground, western end of Big Camas 

 Prairie, Blaine County, Idaho, July 14, 1895. Type in the 

 National Herbarium ; co-types in the Gray and Idaho University 

 Herbaria, as well as in my private collection. 



/ Aplopappus laceratus 



Less than a span high, whole plant glandular with short stipi- 

 tate glands, more or less leafy to the top : leaves rather thin 

 and soft, radical spatulate to narrowly oblanceolate, cauline linear- 

 lanceolate to narrowly linear, green, with long-cih'ated margins, 

 1-4 cm. long, obtuse or acute : involucre campanulate to hemi- . 

 spherical, 1 cm. high and wide, its bracts subequal in two or three 

 rows, lanceolate, acute to acuminate, outer ones green or purplish, 

 inner mainly thin-chartaceous, all with hyaline margins which for 

 the lower half at least are ciliate to pectinately-lacerate : corolla 

 ampliate upwards, deeply 5 -toothed, with style-appendages subu- 

 late and slightly longer than the stigmatic portion : pappus soft, 

 white, not abundant, equaling the corolla : akenes sub-cuneate, 

 striate, densely sericeous. * 



Close to A. Lyallii as well as to A. pygmaeus, but differing de- 

 cidedly from both. From the first it differs in the more lacerate 

 involucral scales, long-ciliate narrower leaves, shorter and broader 

 akenes, and in the compactly caespitose rootstock. From A. 

 pygmacus it differs in being glandular, in having no broad obtuse 

 outer scales, and in the silky, not pubescent, shorter akenes. 



No. 3014. In moist ground amongst rocks, Soldier Mountain 

 near Big Camas Prairie, Blaine County, Idaho, at an elevation of 

 over 10,000 ft., July 15, 1895. 



/Antennaria dimorpha integra 



Plant spreading, with no well-defined caudex : hairs upon the 

 akene almost altogether entire. 



I should hesitate to regard this as a mere variety, in spite of its 

 resemblance to the type, were it not that from its usual habit of 

 spreading by slender, much-divided rootstocks it occasionally de- 

 parts in the formation of quite a decided caudex, which is, how- 

 ever, in all cases more slender than any form of A. dimorpJia in 

 the Gray Herbarium ; secondly, though the hairs in most cases 

 show no division at all, while the ordinary forms of the species 

 show hardly any simple hairs,, yet now and then a hair can be 

 found with notched apex, or with even recurved lobes.
