170 ABERDEEN, FOEFAE, AND DUMFRIES PLANT-NOTES.
leaves, as with S. herhacea; whereas S. Lapponum produces catkins
before its leaves in its early flowering, though in alpine situations
it is often found in fruit when the leaves are mature. The young
leaves of the plant, as well as the mature foliage, are fairly intermediate
between the two parents.
MaJaxis paluclosa Sw. In fair quantity in one spot in the Clova
Valley (90).
"^Juncus squarrosiis L. Moffat Water (72).
Potamofjeton natans L. A starved form, growing in shallow
muddy water near the reservoir, Braemar (92), at an altitude of
about 1400 ft.—P. polygonifolius Pourr., form with narrow leaves.
Peaty puddle near the last, and at the same altitude. Mr. Fryer
said the fruit was not quite right for var. angustifolius Fries, Mr.
A. Bennett said it was a form " towards var. angustifolius Fries."
Carex alpina Sw. Very fine in the same part of Glen Fiagh in
which we have gathered it before. It is not unlikely that botanists
who have failed to find it have been too late for it. The fruit was
beginning to drop in the middle of July last year. In 1887,
another forward season, it had disappeared by the middle of
August.—*C. glauca Murr. Grey Mare's Tail, Moffat Water (72).—
C. pilulifera L. Form with long bracts and remarkably pointed
glumes, the nerve being excurrent ; Glen Fiagh (90), and near
Dhuloch (92). This feature ought hardly to stand as a distinctive
characteristic of C. Saxiimbra Lees. C. Q^deri Ehrh. Clova;(90).
Named for us by Mr. Ar. Bennett. C. fidva x (Ederi. This
hybrid was rather plentiful near Clova and Bradoonie (90). Both
parents were growing freely about ; but in the two spots the hybrid
was the most prevalent. We recognized it without difficulty, and
had the flava form named by Mr. Bennett, as above. C. fidva x
Jlava f. Meadow at Braemar (92). We did not take equal care to
secure the Jiava parent in this case.
Deschampsia ccBspitosa Bea.nv.jf.j^allida Koch. Clova Valley (90).
Prof. Hackel has remarked on a Berkshire specimen of this form,
considering it to be " not a variety, but only a shade-grown form."
It appears to us nothing but an albino ; not necessarily the result
of shade, for our plant was in an open meadow.
Poa Balfourii Bab., var. montana Bab. ? Unich Water (90).
Specimens of this grass, which was new to us, were forwarded
by the kindness of the Rev. E. S. Marshall to Prof.
Hackel, who in an interesting note on the plant queried it as
above ; adding, " Had it grown on our Alps, I should have referred
it without hesitation to P. nemoralis, var. viuntana Gaud., which it
looks very much like."
Festuca rubra L., var. grandifiora Hackel. Eocky slope, Glen
Fiagh (90). This also went to Prof. Hackel, unnamed, who
settled it as above. It has a very different look from the maritime
fonn, which was so named by Hackel for one of us from specimens
from the Norfolk coast about four years ago.
'Bruchgpodlum sylvaticum R. & S. Mofl'at Water (72).
Cystopteris fragilis Bernh., var. dentata Hook. Eocky corrie,
Clova (90). Name confirmed by Mr. J. G. Baker.
