paleaceus, paleis scariosis coloratis duplice ordini 
dispositis, externe radiis circondans, interne disco. 
Radio ligulis 8 ovatis neutris, pappus marginatus 
dentatus.—Obs. This genus differs from Rudbeckia 
by the shape of the perianthe, disposition of the 
chaffs, flat phoranthe, &c. The name means 
Sun's eye. It is, however no wonder, that Robin 
united it with Rudbeckia since so many heteroge¬

species with naked seeds as R. pinnata fyc. must 
form my genus Obelisteca , and those with a sim¬ 
ple perianthe, such as R. columnaris Pursh, my 
genus Ratibida. Raf.
