Hybrid or mixed crosses. - 1. Johnsoni, or Regio-vit-
tatum ; raised by Johnson, who had a small garden in
Lancashire, in 1810 ; by me at Mitcham, in 1811, and at
Highclere later. Am. Braziliensis, Red. Lil. 8. 469. Am.
Carnavoni. De Candolle. Improperly, since the name
Johnsoni had been previously published in the Hort. Trans.
and was in general use. Johnson's cross was probably
accidental, for he thought it a mule between Vittatum and
Sprekelia formosissima, and it passed for such during several
years.
