A small genus differing from Sisyrinchium in the outer perianth-lobes being smaller than the inner and often green, free or almost free filaments, and versatile anthers. Flowers always white, arranged in sub-umbellate panicles. The species are natives of Australasia and South America and rather tender. Named after a Belgian lady-botanist. L. ixioldes is a New Zealand species from 2 to 3 feet high with rigid linear foliage and close clustered simple panicles of white flowers about an inch in diameter. L.
