flower-branches linear and entire; rays about 15, entire, oval-oblong, a little 

 longer than the disk ; pappus fuscous. DC. — Madaroglossa hieracioides, 

 DC. I. c. 



California, Douglas. — Plant a foot high, with the habit of an Echium ; the 

 bristles arising from a black base. Leaves 2 inches long, 6-7 lines broad. 

 Achenia of the disk a little villous : awns of the pappus villous at the 

 base. DC. 



3. L. carnosa (Nutt.) : stem decumbent, hairy towards the surnmit ; leaves 

 succulent, smooth, linear-oblong, incisely toothed; head subsessile, solitary; 

 scales of the involucre linear, obtuse, softly pubescent; rays very small, 2-3- 

 toothed ,- achenia of the ray and disk pubescent; pappus of 18-20 loosely 

 plumose awns. — Nutt. ! in trans. Amer. phil. soc. I. c. p. 393, under Mada-

St. Diego, California, Nuttall ! on the sands of the sea-coast. May.— 

 Plant 3-4 inches high. Lower leaves oblong-spatulate, the coarse teeth ob- 

 tuse. Rays scarcely if at all exserted. Pappus as long as the corolla of the 

 disk, whitish. 



4. L. elegans (Nutt.) : stem decumbent, somewhat hirsute, much branched 

 from the base ; leaves sparsely hispid, Unear-lanceolate ; the radical pinnati- 

 fid ; the cauline laciniate-toothed towards the apex, the uppermost entire ; 

 peduncles and involucre somewhat villous and glandular; rays 10-12, 3-4-

St. Barbara, California, Nuttall!— Awns of the pappus more densely plu- 

 mose towards the base than in L. heterotricha, the long and very fine 

 woolly hairs crisped and interlaced ; and the yellow rays are smaller than in 

 that species. It appears to differ from L. hieracioides by its larger deeply 

 toothed rays, very woolly white pappus, &c.
