A native of the Southern United States; first grown in 
England by Dean Herbert.

loped, by fourteen to sixteen lines broad above the middle, 
narrowed upwards to a non-pungent point, and downwards to 
four to five lines broad above the base, the edge entire and 
concolorous, the texture not thicker than in filamentosa, the face 
flat in the middle half, the outer ones a little recurved. Scape 
robust, twice as long as the leaves. Panicle oblong-lanceolate,
