On comparing the flora of Ireland with that of Great Britain, 

 we find that out of the 1,425 species given by Mr. Watson as the 

 total number of the British flora, we can claim for Ireland only 

 about 950, to which are to be added the few plants which occur in 

 Ireland without reaching Great Britain ; these are as follows :^ 



Helianthemumguttatum(S.W.), Arbutus Unedo (S.W.), 



Arenaria ciliata (S.W.), 

 Saxifraga Geum (8.W.), 

 Saxifraga hirsuta (S.W.), 

 Saxifraga umbrosa (W.), 

 ?Saxifraga Andrewsii (S.W.), 

 ?Saxifraga hirta (S.), 

 ?Saxifraga affinis (S.W.), 

 Inula salicina (W.), 

 Erica mediterranea (W.), 

 ?Erica Mackaiana (if not in 



Dabeocia polifolia (W.), 

 Pinguicula grandiflora (S.W.), 

 Neottia gemmipara (S.W.), 

 Neotinea intacta (W.), 

 Sisyrinchium anceps (W.), 

 Potamogeton longif olius (W.) , 

 Potamogeton sparganiifolius (W.) 

 Naias flexilis (W.), 

 Carex Buxbaumii (N.E.), 

 Asplenium acutum (Bory.) 



Cornwall) (W.), 



With the addition of Hieracia and Rubi, the whole flora may be 

 computed at about 1,000 species, thus amounting to little more 

 than two-thirds of the plants found in Great Britain. 



The deficiencies of the Irish flora will be best seen by a com- 

 parison with Mr. Watson's list (Cylele Briiannica, iv., p. 234), in 

 which the British plants are arranged in order of frequency, 

 commencing with the commonest species. 



Of the first 300 Ireland possesses all. 



In the fourth hundred two are wanting, namely : — 

 Galium cruciatum. Genista anglica.
