The Irish or Florence Court yew is now commonly cul- 

 tivated, and had its origin at Florence Court demesne 

 County Fermanagh, whence its name. The seedling 

 from which the tree (to be still seen at Florence Court) 

 was produced was found " wild " by George Willis in 

 1767. 

 -he tree is female, consequently all trees produced by 

 cuttings are also female. The seeds- produced by 

 crossing the Irish Yew with the common Yew almost 

 invariably reproduce the typical form, and not the 

 variety. This fact provides an interesting Mendelian 

 study. 

 The leaves and seeds are poisonous, the berries are not. 

 The aril or berry induces birds to distribute the seed.
