ON THE BOTANY OF SOUTH PEMBROKESHIRE. ^ 
By Cnanzzs C. Banineron, M.A., F.R.S., ETC. 
The district to which this paper refers is bounded upon three sides 
by the sea: towards the north by Milford Haven, from its mouth to 
Carew Castle, then by the brook which enters the haven at that place; 
_ and from the source of that brook, near East Williamston, an imaginary 
line is carried to the sea below St. Issells. Its length is about eighteen 
miles, and breadth about six. It is a bare and undulating country, 
with no lofty hills, very few trees or woods, and high banks, serving ns 
fences, more frequently than hedges. Nearly the whole of the land is 
under cultivation; the chief exceptions being a considerable tract, of 
furzy heath adjoining the sea in the south-western part of the district ; 
one of sandy dunes at Castle Martin, another at Stackpole ; anda few 
smaller tracts of similar character. The following plants may be men- * 
tioned as being especially the inhabitants of these sandy places :— 
Thalictrum minus, Viola canina, Hieracium umbellatum, Convolvulus 
Soldanella, Carex arenaria, Psamma arenaria, and Triticum acutum. 
The actual coast is usually precipitous or even perpendicular, and 
the shore is seldom accessible without difficulty at any places except — 
those where the brooks find their way to the sea. The shores of Mil- 
ford Haven are not so continuously rocky, but the beach is formed of " 
i 
pebbles. "The following plants occur upon the rocks ;—Matlhuo 
sinuata, Lavatera arborea, Sedum Telephium, Inula crithmoides, and T 
Statice occidentalis, Upon the beach, which is often very narrow, aR 
not rarely absent altogether, may be found Glaucium luteum, Cakile 
maritima, Cochlearia Danica, Senebiera Coronopus, S. didyma, Lepigonum 
rupestre, Eryngium maritimum, Carduus tenuiflorus, Atriplex Babing- :
