George Ehret's other "Belladonna lily" was published by Jakob Trew in Plantae Selectae around 1750.
This is the LilioNarcissus africanus, scilae foliis, flore niveo linea purpurea striato cited under Amaryllis zeylanica in Species Plantarum.
Philip Miller reported that this plant had cultural requirements similar to the West Indies Red Lily, and was more common in Holland than in England. He also stated that he had received seeds and bulbs of this plant from the West Indies, which suggests that he was growing Crinum scabrum.
The name "Belladonna" was used for several species of Amaryllis and Crinum, as listed by Linnaeus.
