Two other species are, so far as the European Flora is con- 
cerned, peculiar to Britain, being natives of North America, 
and they are very interesting because they are certainly both 
truly indigenous, that is, not introduced by human agency. These 
are, — (1) Spiranthes romanzoviana, an orchid allied to our 
ladies’ tresses, widely distributed in North America, but only 
found elsewhere in the extreme south-west corner of Ireland ; 
and (2) Eriocaulon septangulare — the pipewort — a curious 
North American water-plant, found in lakes in the Hebrides and 
the west of Ireland. Along with these we may perhaps class 
the beautiful Irish filmy fern — Trichomanes radicans, which 
inhabits the Azores, Madeira and Canary Islands, the south- 
west of Ireland, Wales, and formerly Yorkshire, hut is not 
certainly known to occur in any part of continental Europe 
(except perhaps the south-west of Spain), though found in many 
tropical countries. 
We may here, notice the interesting fact that Ireland possesses 
no less than twenty species or sub-species of flowering plants not 
found in Britain, and some of these may be altogether peculiar. 
As a whole they show the effect of the pre-eminently mild and 
insular climate of Ireland in extending the range of some south 
European species. The following lists of these plants, with a 
few remarks on their distribution, will be found interesting : —
