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 LittorcUa, 

 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 Rannoch Muir, and deserves further study. — *B. 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 Cairn 

 Toul, Aberdeenshire, at 3500 feet, in 1887. 



Xuphar pumilum Sin. Very abundant in a lakelet adjoining 

 Lochan Dim, near Kingshouse. 



*Nymphaa alba L., var. minor. Syme. Same locality (98). 



Arabis petraa Lam. The Ben Laoigh 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 R. Br. Am Binnein, Ben More (88). 



Cochlearia officinalis L., var. alpina (Watson) Bab. Clach 

 Leathad, Kingshouse, at 3000 feet ; Meall Buidhe, near Inveroran, 

 at 2500 feet ; Am Binnein, up to about 3500 feet. — C. gnenlandica 

 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 serpyllacea Weihe. Glen Falloch. 



Cerastium arcticum Lange. Am Binnein, associated, as on Ben 

 Lawers, with both forms of C. alpinum L. The var. piloso-jmbescens 

 Benth. (pubescens 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. Linncei 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. Railway-banks near Crianlarich ; 

 apparently var. Dillenii (Schultz). 



*Piubus villicaulis Koehl. (teste Baker). Streamside, Inveroran 

 (98).— *R. Chamamorus L. Near Kingshouse, at 2300 feet (98). 



Rosa tomentosa Sm., var. subglobusa (Sm.) Crianlarich. 



Saxifraga nivalis L. Am Binnein. — *S. quinquejida Haw. 

 {S. sponhemica Gmel.) Ben-a-chroin (87). 



*Callitriche stagnalis Scop., var. serpyllifolia Lonnroth, " Obs. 

 Crit. PI. Suec. illustr." p. 16 (1854) (teste Ar. Bennett). Kings- 

 house (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.
