Caliphruria subedentata syn. Eucharis fosteri, given to me by Charles Hardman. Charles says it's easier to flower than Eucharis x grandiflora, which I've only flowered once in 8 years. This is the first time Caliphruria subedentata has flowered for me. The flower and plant are about half the size of Eucharis x grandiflora, and there is no scent that I can detect.
