 tinuous edge splitting off into grey wiry threads, the back marked 

 with grey lines where the edges of other leaves have pressed 

 against it. Peduncle 3-4 ft. long; bract-leaves subulate, the

Hab. Mexico, first described by Prince Salmdyck in 1834. Flowered at 

 Kew in 1875 and 1887. A. Romanl Hort. De Smet, is said to be a hybrid

Hab. Sierras of Southern Arizona, Pringle ! Discovered by the late Dr.
