 rigid, about as broad, striate, apex obtuse to truncate- 

 ly rounded, apical margins thinner and usually deep 

 reddish brown. Heads conically fusiform, 1.5 cm. thick 

 by 5 cm. long, erect, terete, pointed, upon slender im-

 base, nearly 4 cm. long, tapering from the base to the 

 obtuse apex, striate, glabrous, closely imbricated, of a 

 dull flesh red; bracteoles 4 cm. long, 5 to 8 mm. wide, 

 glabrous, striate, margins subhyaline, widest and clasping 

 toward the base, gradually tapering to the acute point; 

 calyx 3.5 cm. long, slenderly tubular below the middle, 

 subinflated above the middle, glabrous, obscurely striate, 

 terminated into one or two acuminate points, the apical 

 two thirds open on one side; corolla tube slenderly fil- 

 iform, glabrate, nearly twice as long as the calyx; lat 

 eral lobes pink to white, 1.5 cm. long, oblong, hyaline, 

 obscurely parallel veined, 5 mm. wide below the middle,
