NEW SPECIES FROM MARIPOSA COUNTY. 185 



abundantly different from our other species, E. fabacea var. campes- 

 tris, which ascends from the plains only a short distance into the 

 foot-hills. It differs from the macrocarpa of Greene in the campan- 

 ulate corolla and in the shape of the seeds. 



Selinum validum. Plant stout, tall, usually strongly pubes- 

 cent in all its parts. Stems 3 to 6 ft. high, leafy. Leaves biter- 

 nately or bipinnately divided, usually broadly ovate in outline, 

 sometimes nearly a foot in diameter ; the ultimate leaflets usually 

 ovate, serrate, usually acuminate, 1 to 2 ft. long. Fruit and 

 inflorescence about the same as in S. capitellatum Benth & Hook. 



The present species, S. capitellatum and S. eryngifolium Drew, 

 are three closely allied and perhaps confluent forms. Their in- 

 florescence and fruit are almost identical, but they differ greatly in 

 foliage and in general appearance. S. capitellatum is often nearly 

 or quite glabrous, with rather slender few-leaved stems, long 

 peduncled umbels; the leaves long-petioled, pinnately or bipinnately 

 divided ; the ultimate leaflets narrowly -oblong to lanceolate. It is 

 in our region mostly confined to the east side of the main Sierra. 

 S. eryngifolium has a more condensed growth with leafy stems and 

 shorter-peduncled heads; the leaves bipinnately dissected into oblong 

 or lanceolate very acute or mucronate ultimate segments only ^ to 

 ^ in. long. It grows for the most part in the high mountains at 

 8,000 to 11,000 ft. S. validum differs in the particulars named 

 above and belongs to the western slope of the mountains descending 

 with the streams to the foot-hills. It is particularly abundant near 

 Wawona. 



Erigeron flariposanus. Perennial, with slender, more or less 

 decumbent stems, o to 10 in. high, from slender, running root- 

 stocks. Plant strongly but rather sparsely setose-hispid, the bristles 

 often with pustulate base. Leaves 1 to IJ in. long, narrowly 

 obovoid-oblong, varying to oblong or above even to linear-filiform, 

 entire, veiny, sessile or tapering to a very short petiole, with a strong 

 midvein, either abruptly acute or obtusish at apex. Heads solitary 

 or 2 to 5 in a loosely branching corymb, ^ to f in. in diameter. 

 Involucre of about three series of linear appressed, almost strigosely 

 pubescent bracts, externally herbaceous. Rays 15 to 30, rather 

 broad, pink to whitish. Pappus simple, strongly scabi'ous under a 

 ens. Achenes sparingly hirsute, flattened.
