Notes on Some Curiosities of Orchid Breeding

(quoting T. L. Mead in Orchid Review, 4(47): 326. 1896)

Laelia anceps pollen seems invariably to cut down time needed to ripen pods of Cattleya labiata group by about six months; while the pollen of C. labiata does not appreciably lengthen the time needed by L. anceps pods to ripen .... Broughtonia sanguinea, which both with its own and with foreign pollen ripens its seeds in one-and-a-half to two months, has power to quicken the ripening of C. Bowringiana, with which it gave good seed in eight-and-a-half months."
