Utricularia intermedia, Menyanthes trifoliata, Juncus fluitans, and 
other terrestrial forms of J. supinus, Eriophorum polystachion, and 
over the drier parts tussocks of Scirpus csespitosus, Molinia coerulea, 
and Carex echinata. Loch Aslaich has an island with trees of 
considerable size, due to its sheltered position (fig. 60). These trees 
were probably planted, as there is a bothy on the little island, 
used by keepers when stalking deer. The terrestrial form of 
Sparganium minimum, mentioned on p. 977, is illustrated in 
the foreground of fig. 61, which is from a loch north of Loch, 
Aslaich. Dwarf forms of Castalia speciosa growing on peaty mud 
are shown in fig. 62. Menyanthes trifoliata, overgrowing peaty 
mud, with its rhizomes exposed, are seen in fig. 63. Perched 
rocks are a common feature of this desolate region. The one shown 
in fig. 64 is 26 inches high and 10 feet in circumference, in the 
form of a flattened sphere. It is so delicately poised that it can 
be rocked 2 inches with the little finger of one hand. The 
lochs of this extensive region, containing about 100 square miles 
of mountain and moor, are characterised by a general paucity, not 
only of variety, but also in quantity of phanerogamic plants. In 
the following list for this district many of the plants occur both 
in normal and in dwarf depauperated forms, in accordance with 
environment : — Ranunculus Flammula, Caltha palustris, Castalia 
speciosa, Epilobium angustifolium (about half-a-dozen plants at 
Loch a Choire Bhuidhe, probably introduced here by ducks ; large 
numbers of these birds are bred at the Balmacaan estate for 
sporting purposes), Myriophyllum alterniflorum, Callitriche hamu- 
lata, Lobelia Dortmanna, Menyanthes trifoliata, Littorella lacustris,. 
Utricularia vulgaris, U. intermedia, Juncus articulatus, J. supinus,,
