from the Continent as C. capitata. But the C. capitata (Wahl.), is 
8S. aurantiacus (3. of Reichenbach (Iconog., t. exxviii., figs. 248 and 
244), which is quoted by Reichenbach fil. as S. aurantiacus, and is

C. capitata appears to be only a rayless state of C. aurantiaca, as it 
is understood to be by most, if not all authors. It has the “flores 
rubro-aurantiaci” of C. aurantiaca, but not usually the radiant 
florets. 
C. capitata of Hoppe is a rayless form of C. pratensis (Hoppe). 
It is figured by Reichenbach (Iconog. t. cix., f. 219). 1 have a 
plant. 
I am greatly indebted to Mr. Backhouse for allowing me to 
examine the specimen sent to him
