The species is recognized by the large, robust plants, the cymbiform floral bracts apically rounded, inflorescence compact, dense, 2.8 to 5.2" [7 to 13 cm] long, and bears up to 20 successive lilac flowers, sepals very fleshy, .56 to .64" [14 to 16 mm] long, petals obovate-elliptic, nearly as wide as the sepals.
