   • 1840, Mr. Adam White, “Note on Peloria”, in Annals of Natural History, volume 4:

     I am indebted to a friend for the sight of a pelorian variety of a species of Tropæolum, and have also much pleasure in showing the Society an imperfectly developed pelorian variety of the pretty Pinguicula vulgaris, which I gathered on Roydon Fen, near Diss in Norfolk, in the summer of 1835.

   • 1852, John Hutton Balfour, Class Book of Botany:

     In some gamopetalous corollas with a single spur, it happens occasionally, that what are called Pelorian varieties occur in which five spurs are produced.

   • 1887, Report of the Meeting of the British Association for the Advancement of Science, volume 56:

     In this note the author adverted to bo much of the normal structure of Orchids in general, and of Cypripedium in particular, as is necessary for the elucidation of his subject, and proceeded to describe a case of regular peloria in Cypripedium caudatum, which shows a reversion to the typical form of Orchids, and goes to prove that the so-called genus Uropedium was only a pelorian form of Cypripedium.
