 2 lines broad above the broad sheathing base; scapes 9 to 18 

 in. long ; sheath 1^ to 2i in. Flower-heads ^ to 4^ lines in 

 <liameter ; involucral bracts 1 to 1~ by a little over ^ line, floral 

 bracts n to 1 by ^ to ^ line ; sepals of female 4 to I by i to

 petal li by 4 line, others 4 by 4 line ; sepals of male 4 to 1 by i to 

 scarcely 4 line ; pedestal between calyx and corolla ^ line long, the
