 fertile, shortly ligulate, with exappendiculate recurving style- 

 branches; the inner ones numerous, discoid, apparently barren, 

 hermaphrodite ; the corollas tubular, i to f in. long, gradually 

 widening in the upper half, shortly 5-lobed, the tube scattered 

 with some short hairs; the lobes lanceolate, obtuse, thickened 

 and dark at the tip ; the anthers included or nearly so, y\ in. 

 long, scarcely appendaged at the apex, subobtuse and exappendicu- 

 late at the base but the upper halves of the filaments thickened ; 

 style included, not branched, only notched at the apex ; young 

 achenes rather slender, i in. long or nearly so, 10-ribbedor -striate, 

 setulose, with a narrow whitish cartilaginous ring round the apex 

 from which arises the copious white setose pappus ; the setaj ^ in.

 rather rare ; 4000 ft. elevation ; fl. and young fr. Oct. 1K59. No. 3634. 



Nearly related to 0. scapigcni Harv. ; it has much more numerous

 small, subulate ; involucral scales 8, uniseriate, linear-oblong, 

 pointed at the apex, scarious on the lateral margins, i to |- in.

 after the fall of the fruit separating and spreading ; flowers 

 yellowish, perhaps all hermaphrodite ; about ^ in. long, corolla 

 tubular, exceeding the involucre, shortly 5-lobed, the outer ones
