 thinly woolly or puberulous on the back, scarious on the margins-, 

 ^ in. long or rather more, each arising from the exterior circum- 

 ference of the receptacle just above thickened points or adpressed

 fertile, shortly ligulate, with exappendiculate recurving style- 

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

 hermaphrodite ; the corollas tubular, ^ 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, -jV in. 

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

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

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

 achenes rather slender, i in. long or nearly so, 1 0-ribbed or -striate, 

 setulose, with a narrow whitish cartilaginous ring round the apex 

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

 rather rare ; 4000 ft. elevation ; fl. and young fr. Oct. 1869. No. 3684. 



Nearly related to 0. scapigera Harv. ; it has much more numercus

 bracteate pedicels ranging up to If in. long, arranged in a rather 

 lax terminal corymbose cyme of 2 to 8 in. in diameter ; bracts 

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

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

 long, erect, cohering at the base for a short distance, at length 

 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 

 somewhat spreading ; anthers shortly exserted, narrowed, obtuse
