(the plant) produced flowers in the hothouse in December 1861. The plant has a very showy appearance in the conservatory, twining along the roof of the house to the extent of ten or twelve feet, and giving off numerous clusters of flowers. The contrast of colour presented by its white calyx and crimson corolla render it a desirable plant for cultivation... (Rev. Thomson) expressed and opinion that the plant was new, and if so, he wished it to be named after his late wife.
Named for the wife of Rev. W. C. Thomson, a missionary at Old Calabar on the west coast of Africa. Rev. Thomson sent the plant in a Wardian case to the Royal Botanic Garden in Edinburgh.
A report of the proceedings of the Edinburgh Botanical Society in Gard. Chron. 1862: 70 is cited as the publication of the name by PlantList.
