42 KEPOET OX TWO BOTANICAL COLLECTIONS FROM 



tomentose, bearing a few small leaf-like bracts at the base of the very short branches 

 of the corymb. Heads sessile, densely crowded, about 1 lin. long, 1 -flowered. Involucre 

 cylindric-conical, with 12-16 spirally imbricating scales, the innermost about 3i lin. 

 long, |-1 lin. broad, narrowly lanceolate obtuse, glabrous, the outer gradually shorter 

 and more and more ovate, and more or less tomentose on the back. Floret not exceeding 

 the involucre (?), hermaphrodite. Corolla regular, very deeply 5-lobed, glabrous, the 

 lobes about 2J lin. long, linear, acute, incurved at the apex. Stamens with free 

 filaments and syngenesious anthers, which are produced at the base into long, slightly 

 barbed tails. Achenes 2J lin. long, subterete, slightly grooved, glabrous. Pappus- 

 bristles copious, 3-4 lin. long, nearly smooth or very slightly scabrid, pale tawny-white.

This plant appears to be nearly allied to the genus Mbquinia, DC, but differs in habit 

 and in its 1-fiowered, densely-crowded heads. I am somewhat doubtful as to the 

 exsertion of the floret from the involucre during flowering, as I have only seen the 

 corollas in the bud state; when in fruit the achene is as long as the involucre and the 

 pappus is entirely exserted.
