Pbaeger — On Types of Distribution in the Irish Flora. 5 



are those wHch have been practically thoroughly explored ; namely, 

 Kerry and Cork, Dublin and "Wicklow, Donegal, and the North-east. 

 As these areas are widely scattered, the figures may be worth compar- 

 ing, especially since the divisions in question are all maritime, which. 

 renders them more comparable : 



Antrim, 



. . 375 



North Kerry, 



. 361 



Do-ff-n, 



.. 372 



West Cork, 



. 369 



Derry,

"Wicklow, 



. 359 



East Donegal, 



. . 363 



South Kerry, 



. 356 



"West Donegal, . . 



.. 362 



Dublin, 



. 356 



East Cork, 



.. 362 



Mid Cork, 



. 351 



The smallest number on record is 297, in Monaghan — the least 

 worked of all the Irish divisions. 



It should be noted, however, that the whole of these British type 

 plants are not widely spread in Ireland. There are a few notable 

 exceptions. One, as already mentioned, is absent from this country. 

 A few others are very rare therein, as exemplified below, where the 

 first number shows in how many of the British 112 vice-counties each 

 species occurs, the second number in how many of the L'ish 40 :

2. English Type : " Species chiefly seen in S. or S.M. Britain." 

 — These are the southern plants of Great Britain, having their head- 

 quarters in the south of England. They are largely lowland species 

 favouring light soils. 



As typical " English" plants, "Watson selects the following : — 



Ehamnus catharticus. 

 Ulex nanus. 

 Tamus communis. 

 Bryonia dioica. 

 Hottonia palustris. 

 Chlora perfoliata. 

 Sison Amomum. 



Linaria Elatine. 

 Eanunculus parviflorus. 

 Lamium Galeobdolon. 

 Hordeum pratense. 

 Alopecurus agrestis. 

 Ceterach officinarum. 



Of these, six are unknown in Ireland in the native state ; of the rest, 

 Chhra and Ceterach are the only ones which are not rai'e and local.
