FLORA OF THE SCILLY ISLES. 103 
Tresco is the island on which Mr. Smith, the present owner of the 
whole group, has fixed his abode, and a walk through his tastefully 
laid-out pleasure-grounds and gardens will afford abundant proof of 
the mildness of the climate, for here are to be found, flourishing in 
air, many plants, shrubs, and trees, uatives of much more southern 
latitudes. * There is a considerable extent of sandy ground, near 
Crow. Point, with sand-hills, on which occur Psamma arenaria and 
Euphorbia Portlandiea, etc. A large and shallow freshwater pool 
nearly divides the island, and on its shores grow Elatine hexandra, 
Littorella lacustris, ete... The interesting purple-flowered Trefoil, of 
which a figure was given in No. 13 of this Journal, grows very abun- 
dantly on the flat sandy ground south of the pool, On sloping ground 
to the south-west of the pool is a plantation, consisting chiefly of 
Pinus maritina, P. sylvestris, and. Acer Pseudoplatanus. Below it is 
a withy-bed. Almost the whole of the island north of New Grimsby 
Harbour, and the part above Apple-tree Point, is waste, the herbage 
being stunted heather, gorse, ete. To the west of this, between 
Braiden Point and Olivers Castle, occurs Luphorbia amygdaloides ; 
Pteris aquilina is here very fine. This is a sheltered spot, and might 
repay further examination. 
St: Agnes lies to the extreme south, and is more exposed than the 
other islands; barley is the only grain cultivated on it. The centre of 
the. island. is generally under culture, but the land round the coast is 
waste, and. the herbage very starved, in many places not rising above an 
inch from the ground. To the south-east, near linflat Point, it con- 
sisted of the following plants :—Sagina procumbens, Trifolium minus, 
Lotus corniculatus var., Radiola Millegrana, Sedum Anglicum, Plantago 
Coronopus; P. lanceolata, Anagallis tenella, Armeria maritima, Calluna 
vulgaris, Festuca rubra... In a grass field, probably only two years old, 
the crop consisted of Serrafalcus mollis, Holcus lanatus, Poa trivialts, 
Lolium perenne. Another. grassfield was, however, most rich in a fine 
growth of Lotus hispidus, a foot high, and looking as if it had been in- 
tentionally sown, but I was informed it was not. ‘This island is the 
reputed habitat for Acanthus mollis, but I did not observe it. ‘There
