Pl. Rar. Hort. Genev. Plate 9. 1829
Amaryllis x carnarvonia
A. C. de Candolle

This plant resulted from xJohnsoni backcrossed to Vittata. It resembles the Amaryllis vittata-rubra (below right) from an anonymous German collection of 1854.

Bury's xJohnsoni


Old House Gardens carries a version of Amaryllis x johnsoni very similar to this Amaryllis rubra-vittata in their Rare and Unusual section.

Amaryllis regina-vittata of Trans. Roy. Hort. Soc. (1820) is yet another variation on the "Johnsonian" theme.
