Botany in Derry
Benevenagh and Magilligan. The northern elements in the Ulster flora attains specially well-marked development on the magnificent basaltic precipices of Bene- venagh, an isolated hill in Co. Derry (Bed and Breakfasts, Derry, Ireland) lying near the north-western extremity of the basaltic area. The cliff flora there includes :
Draba incana Hieracia (many species)
Silene acaulis Salix herbacea
Dryas octopetala Juniperus nana.
Saxifraga oppositifolia
Spreading out below the Benevenagh cliffs is the wide sand-flat of Magilligan, which is also excellent ground for the botanist. Draba incana descends from its alpine perch to grow in abundance on the dunes ; Hypochaeris glabra has here its only Irish station ; and some other species which are rare locally, such as Orchis pyramidalis, Epipactis palusiris, and Lastrea Thelypteris, may be also found.
