Cephalanthera damasonium x longifolia

(Hybrid between Large White and Sword-leaved Helleborine)

This hybrid has occasionally been recorded in Southern England in woodland containing the two parents, but it is quite a rarity here. While the leaves look similar to those of the Large White Helleborine, the bracts below each individual flower are small, more like those of the Sword-leaved Helleborine. The flowers are intermediate in appearance.
