xHippestralia 'Martinique'

From Luther Burbank's 1909 catalog

A cross between Sprekelia formosissima, the Jacobean lily, and a Hippeastrum vittatum hybrid.

"The flowers are fiery crimson—like those of the Jacobean lily but very much larger. The blooms are nine inches in diameter and are even more remarkable for their long curious, twisted petals, which give the flower a strange appearance and which is not found anywhere among the Amaryllidaceae. The leaves are pale green, upright, strap-shape, one inch wide and eighteen to twenty inches long."

Seed capsules were produced abundantly but with rarely a viable seed.
