ribs vertical, straight, sub-acute, an inch and a half apart 

 at about the middle of the stem, closely covered with 

 minute, brown, rugulose tubercles in a single series ; sinus 

 between the ribs shallow, acute at the base. Involucres 

 solitary on the tubercles at the crown of the plant, very 

 shortly peduncled ; peduncle about one-tenth of an inch 

 long, covered with obtuse, imbricating, fleshy, ciliolate 

 bracts, the three upper longest. Involucre about as long 

 as the peduncle, campanulate ; lobes five, minute, short, 

 broad, incurved, hispid ; interposed glands three times as 

 large, orbicular, fleshy, quite entire, punctate. Filaments 

 anantherous, hirsute. Ovary nearly sessile. Style rather 

 short, stout ; stigmas large, revolute. — J. D. H.
