210 ISOLATED STATIONS OF PLANTS. 
two persons are mostly without a fireplace, both at Mucruss and 
the Lake Hotel, while those for single persons generally have it. 
T left Killarney on the 19th of July, going by rail to Carrick- 
on-Suir, and the next day paid a visit to a hollow in the Com- 
merach mountains, containing a pool (Loch Looscannagh) of 
about forty acres. A good road will take you close to the foot 
of the mountain; but the rocks are so dry, that you soon give up 
hopes of getting anything from them. There are pools higher 
up, and there is also a tract of bog on the mountain-top, and 
perhaps there something might be found. I gathered Sawi/raga 
hypnoides, which I had not before seen in this ramble. Three 
days later I went from Waterford to Tramore, and botanized, 
first on a sandy track to the east of the town, whence I observed 
the very pretty Convulvulus Soldanella, and Euphorbia portlandica. 
Juncus acutus was also there, and a very handsome variety of 
Erythrea Centaurium. There was also a rayless form of Senecio 
Jacobea. Afterwards I visited the very broken and rugged rocks 
to the west, and had great pleasure in observing the quantity of 
Inula crithmoides. Crithnum maritimum and Rubia peregrina, 
among the lesser rarities, were also conspicuous. On the 24th I 
left Waterford and Ireland, and a passage of about twenty-four 
hours landed me at the Cumberland basin at Clifton.

Isolated Stations of Plants. 
Besides the two very comprehensive classes of causes selected 
by the writer of the short notice in the ‘ Phytologist’ (page 120), 
namely, “Geological and Atmospherical,” may we not suppose 
that there is yet a third reason for the unequal distribution of 
plants, to be sought in the comparative constitutional vigour 
and reproductive powers of the different species? For now that 
plants have fulfilled their object, and occupied the soil, is not a 
strong race found to hold its own, nay, to encroach, while one 
of weaker powers gives way in proportion, and dwindles down to 
a few scattered stations, being either ousted by the more vigor- 
ous stock, or finding the localities to which it might extend 
already appropriated ?
