510 RARE PLANTS IN ABERDEENSHIRE. 
miles to west of Aberdeen. I could find no other localities for 
this plant, and from the information gathered respecting it, this 
seems to be one of the scarcest of northern plants. 
Plantago maritima is very common as a roadside plant, occur- 
ring far inland from twenty to thirty miles frequently,—all the 
way from Huntley to Grantown. 
A trip to the Loch of Drum, Kincardine (fifteen or twenty 
miles from Aberdeen), for Isoetes lacustris, proved this to be a 
capital botanical station. The Loch is a shallow piece of water, 
scarcely over four feet in depth at any part, extending over a 
surface of from eighty to ninety acres; the favourable depth of 
water renders it suitable for many aquatic plants, and the bottom 
is literally carpeted with plants. I found Isoetes lacustris, Subu- 
laria aquatica, Itttorella lacustris, Lobelia Dortmanna, Chara 
vulgaris, Nitella translucens, Utricularia vulgaris, U. minor, Po- 
tamogeton lanceolatus, Hquisetum fluviatile, Scirpus lacustris, Pi- 
lularial gobulifera, near the lake, Radiola millegrana, Ophioglos- 
sum vulgatum, Goodyera repens, Trientalis europea, Parnassia 
palustris, (Nuphar lutea in the lake). I gathered also a pretty 
Nymphea, with small white flowers, in shallow sedgy water about 
two miles above the Loch towards the mountains; it is probably 
the variety of Nymphea alba, known as N. minor. The plant is 
very distinct, resembling the American N. odorata; leaves from 
four to six inches in diameter ; flowers about the size of a shilling- 
piece. TI have never seen this form under cultivation, but it will 
be a nice addition to the small aquarium, and I have managed 
to get home some plants in safety. 
Expecting to find Polypodium alpestre, a common Fern on 
most of the mountains north of the Dee, I ascended some of the 
principal elevations, but without success, although some heights 
must have been over 3000 feet. The first appearance of this 
occurred on Loch-na-Gar, ascending it from the falls known 
as the Gar Vault; but here it was not “plentiful but sparingly 
distributed in correis with a singular-looking Lasrrea, almost 
destitute of an mdusium ; eievanen about 3500 feet. “Azalea pro- 
cumbens was plentiful, Aes Silene acaulis, Lh ycopodium annotinum, 
the usual Savifragas, as stellaris, aizoides, hypnoides and dpposi- 
tifolia, the rare Phleum alpinum, and, lower down where once . 
a Birch-forest stood, Betula nana; this was growing singularly 
alone, ‘unaecompanied even by the common Ling.
