Eyebright, Irish,

There are 17 entries in the Census Catalogue of the Flora of Ireland (1987) under this genus, several being hybrids.  It is a very difficult genus to identify and therefore I am only giving a general description of these wildflowers.  They are short annuals which are semi-parasitic, obtaining their nourishment from the roots of Clovers, Plantains and grasses among whom they grow. Their 2-lipped flowers (5-10mm long) are white, often tinged pink or violet, with purple veins or a yellow blush within the corolla.  The upper lips are hooded with 2 lobes, the lower lips spread and 3-lobed.  The flowers are borne in leafy terminal spikes and the small leaves are sessile, the lower opposite, the upper often alternate.  These plants bloom from June to October in undisturbed grassy places, are native and belong to the family Orobanchaceae. 

My first record of an Eyebright was in 1973 in Cleggan, Co Galway.  The photographs were taken at Ballyheigue, Co Wexford in 2007.
