 1. p. 50. Gaillardia odorata, Lindh. hied. G. simplex, 

 Scheele in Linncea, 22. p. 160. Rocky prairies, near San 

 Antonio and New Braunfels. April and May (646). — The 

 genus is very near Gaillardia, from which it is distinguished 

 by the fertile but usually deformed rays, the globose and 

 alveolate receptacle, and by the style, the branches of which 

 are tipped with a penicillate tuft, but not prolonged into a 

 filiform hispid appendage ; and the habit is peculiar. The 

 flowers are deliciously sweet-scented, the fragrance much 

 like that of the Heliotrope ; the short rays are cherry-red or 

 dark purple, and yellow only at the tip, as in several species 

 of Gaillardia ; the earliest heads are rayless. The leaves 

 vary from lyrate-pinnately parted, with linear segments, to 

 obovate and barely-toothed or incised towards the base. — 

 Agassizia, Chavannes, is Galvesia, Dombey. Agassizia, Spach, 

 is Sphserostigma, Seringe, and Holostigma, Spach, by most 

 authors received only as a subgenus of Oenothera. 



(103.) Gaillardia picta, Don. Near Victoria. More 

 upright, and the deeply incised rays more cuneate than in 

 the plant from Galveston. 1

1 I cannot make out what Gaillardia tuberculata, Scheele, I. c. p. 349, (described 

 from Roemer's collection) can be; neither G. Kipmcriana, Scheele, I. c. p. 1G1, 

 unless it be Aclinclla scaposa.
