Euphrasia officinalis

Succeeds in most soils, preferring chalk or limestone. Eyebright is a semi-parasitic plant, growing on the roots of various species of grass and also on Trifolium pratense and Plantago species. The grass does not seem to suffer unduly from this parasitism since eyebright is an annual and its cells do not penetrate very deeply into the grass. There is some doubt over the validity of the name of this species, some botanists now call it Euphrasia rostkoviana. Eyebright is a variable aggregate species, some botanists divide it into a number of different species[1, 50]. Only those forms of eyebright which have glandular hairs on the calyx possess medicinal qualities. It hybridizes freely with other members of this genus.
