180 NOTES ON HIGHLAND PLANTS.
connecting link with the assumed type. A weak stem, which
became decumbent and lived through last winter, developed three
nodal-rooting plants, the leaves of which had the look of LittoreUa,
already mentioned ; but they have since died. It has not flowered
in cultivation hitherto, and a specimen sent to Mr. Bennett soon
died. This form is probably frequent on the gravelly lake-margins
of Kannoch Muir, and deserves further study.— *i^. Steveni Andrz.
A beautiful buttercup, which is placed here by Messrs. Beeby,
Bennett, and Townsend, was gathered sparingly, in flower only, at
about 2700 feet, on granite, near Kingshouse (98). It has a
horizontal root-stock, and the leaves are firm in texture, with
broad lobes. The same form was gathered by F. J. H. on Cairu
Toul, Aberdeenshire, at 3500 feet, in 1887.
Nuphar pumilum Sm. Very abundant in a lakelet adjoining
Lochan Dhu, near Kingshouse.
"^Nymphma alba L,, var. minor. Syme. Same locality (98).
Arabis petrcea Lam. The Ben Laoigli form seems to us fully
deserving of Mr. Druce's varietal name ; its sub-entire leaves and
large and sometimes purplish flowers at once distinguish it. At
first sight, one would hardly take it for the same species as that of
the Braemar district.
Draba rupestris E. Br. Am Binnein, Ben More (88).
Cochlearia officinalis L., var. aljnna (Watson) Bab. Clach
Leathad, Kingshouse, at 3000 feet ; Meall Buidhe, near Inveroran,
at 2500 feet ; Am Binnein, up to about 3500 feet. C. grcenlandica
L. Am Binnein, from 3300 to 3500 feet. Clearly identical with
the Ben Lawers plant passed as this species by Prof. Babington.
Subularia aquatica L. Loch Tulla (98) ; Loch Dochart (88).
Polygala serpxjllacea Weihe.
Cerastium arcticum Lange.
Glen Falloch.
Am Binnein, associated, as on Ben
Lawers, with both forms of C. alpinum L. The var. piloso-pubescens
Benth. {jmbescens Syme) of the latter was also met with in Innis
Choarach, Meall-na-Soane.
Sagina procumbens L., ascends to quite 3300 feet on Am
Binnein. S. Linnai Presl. Meall Buidhe (98) ; Ben Laoigh and
Innis Choarach (88). S. nivalis Fr. Our visit to Am Binnein was
mainly in order to search for this plant, once found there many
years ago. A single fine and typical specimen was obtained at
about 3500 feet.
Anthyllis Vidneraria L. Eailway-banks near Crianlarich
apparently var. Dillenii (Schultz).
*FMbus villicaulis Koehl. (teste Baker). Streamside, Inveroran
(98).— *jR. ChamcBmorus L. Near Kingshouse, at 2300 feet (98).
Rosa tomentosa Sm., var. subglobosa (Sm.) Crianlarich.
Saxifraga nivalis L. Am Binnein. -'-S. quinquejlda Haw.
(S. sponhemica Gmel.) Ben-a-chroin (87).
*Callitnche staqnalis Scop., var. serpyllifolia Lounroth, " Obs.
Crit. PI. Suec. Illustr." p. 16 (1854) (teste Ar. Bennett). Kingshouse
(98), on mud. What is probably the same form was seen,
but not taken, by the shore of Loch Dochart. Mr. Bennett has it
from W. Sutherland,
