A stout handsome leafy rhizomatous herb 2-5 ft. high, usually 

 suberect with the spike erect. Leaves thinly appressed-silky, pubes- 

 cent or quite glabrous beneath, sub-patent, lanceolate, 1-2 ft. long, 

 variable in breadth, sessile. Flowers fragrant, usually pure white 

 (in our area), a few" opening at a time exserted from the axils of the 

 very closely imbricate orbicular or oblong-obovate very broad bracts 

 of the large conical 4-7"-long head, the loAver bracts sterile, the upper 

 each containing a cluster of 3-4 floAvers, the special bract of each 

 flower enclosing all the special bracts of the next younger floAvers.
