Viola Mrta : east and west (on the median line). 
Sagina apetala : throughout Ireland ; exceptional ; not common 
in the north. 
Stellaria glauca : chiefly midland ; not found in the north. 
Zinum angustifoUum : south-west, south, and south- east to the 
median line. 
Malva moschata: native only in south and south-midland of 
Ireland. 
Lavatera arhorea : maritime and douhtfuUy native, excepting, 
perhaps, Dublin and Galway, on the median line (Howth and 
Arran). 
Erodium maritimum : southern and south-eastern chiefly, but 
reaches north-east, being maritime. 
Geranium colmnhinum : southern and south-eastern to the median 
line ; extending sparingly also to the north-east ? 
Euonymus europceus : chiefly southern, but extends, with lime- 
stone, to the north at Loughs ^^"eagh and Erne. Just reaches 
Donegal. 
RTiamnus eatharticus and R. frangula : following somewhat 
similar laws as the last, but much rarer, especially M. fran- 
gula. Neither occur in the extreme northern county, 
Donegal. 
Ulex nanus: typical U. nanus ^7. eu-nanus^^) is not found in 
Ireland. The form which does occur is U. gallii, and it is

west and extreme north. Eather exceptional, but quite 
aquatic. 
Cornus sanguinea : west and north-west. Follows the limestone, 
like Rhamnus and Euonymus. Yery rare, however. 
Apium graveolens : brackish marshes ; much commoner south- 
wards, but hard to decide where native.

tional, but very rare, and not reaching Donegal.
