Scheele in Linnea, 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 Spherostigma, Seringe, and Holostigma, Spach, by most 
authors received only as a subgenus of OCinothera.

1 I cannot make out what Gaillardia tuberculata, Scheele, 1. c. p. 349, (described 
from Roemer’s collection) can be; neither G. Reemeriana, Schecle, l. c. p. 161, 
unless it be Actinella scaposa.
