What is "lactoris"

Lactoris fernandeziana is a flowering shrub endemic to the cloud forest of Masatierra — Robinson Crusoe Island, of the Juan Fernández Islands archipelago. It was formerly placed in Aristolochiaceae, but as of the APG III (2009) is now placed alone in the family Lactoridaceae, in the order Piperales.

Morphological data are not clear concerning the classification of Lactoris, but molecular data place it in the Aristolochiaceae.
