Legousia (Venus' looking-glass) is a genus of flowering plants in the family Campanulaceae, native to Europe. Species in the genus used to be placed under genus Specularia along with plants in genera Triodanis and Heterocodon as well as some species in genus Campanula. However, the division has been confirmed evolutionarily comprehensive by a Campanulaceae phylogeny based on DNA molecular evidence.[1]
Species

Legousia species include:

Legousia falcata (Ten.) Fritsch ex Janch. 1907
Legousia hybrida (L.) Delarbre 1800
Legousia julianii (Batt.) Briq. 1931
Legousia pentagonia (L.) Thell. 1908
Legousia scabra (Lowe) Gamisans 1985
Legousia skvortsovii Proskur. 1980
Legousia snogerupii Tan, Biel & Sfikas. 2015
Legousia speculum-veneris (L.) Durande ex Vill. 1786

A 2019 article in Willdenowia proposes that L. pentagonia should be considered as a subspecies of L. speculum-veneris, L. castellana and L. scabra be reduced to L. falcata and L. skvortsovii be reduced to L. hybrida.[2]
