ADDITIONS TO THE FLORA OF BUCHAN 99 



Thymus Serpyllum, L. Quite common in a few localities ; this is a 

 scarce plant in most parts of Buchan, and I have noted its 

 occurrence in only nine parishes of the twenty-six. 



Teucrium Scorodonia, L. Also a local plant, having been observed 

 in only two parishes in 1900, but in six others in 1901. It is 

 locally abundant on rough banks near streams. 



Littorella juncea, Berg. Has now been found in nine parishes of 

 North Aberdeen. 



Atriplex hastata, L. Is not plentiful, but is pretty generally 



distributed. 

 A. laciniata, L. 93'% a few on the sandy beach near Rosehearty. 



Rumex crispus x domcstiais ( = propinquus, Aresch.), R. crispus x 

 obtusifo lius ( = acutus, L.), and R. domesticus :c obtusifolius 

 ( = conspersus, Hartmann), were all found growing at Glasslaw 

 in Aberdour, on waste ground, where the three parents were all 

 plentiful, in close proximity to one another. 



Euphorbia Pepli/s, L. As a garden-weed, locally common, but not 

 of general occurrence. 



Salix repens, L. Not a frequent species, though occasionally 

 plentiful. Observed in only seven parishes. 



Populus tremula, L. In several localities, e.g. near the Bridge of 

 Alvah ; but the only locality in which I have seen it apparently 

 native is beside the Water of Cruden, opposite Uppermill. 



Elodea canadensis, Michx. 94*, abundant in the Deveron below 

 Turriff. The lake at Pitfour, Old Deer, is very full of it. 



Orchis mascula, L. Locally plentiful on the coast of Cruden near 

 Southend, and on the coast of Gamrie near Melrose. 



Orchis maculata, L. Among specimens collected in Aberdour are 

 some that probably belong to ericetorum, Lin ton. 



Habenaria viridis, R. Br. Rosehearty Links. 

 Allium nrsinum, L. Den of Auchmedden. 



Typha latifolia, L. In several localities, e.g. in Lonmay, at Pitfour 

 in Old Deer, at Plaidy in Turriff, and at Ashogle in Alvah, 

 but introduced by man into each locality. 



Sparganium simplex, Huds. Near Fraserburgh. 



5. affine, Schnizl. Loch of Glasslaw, Aberdour ; burn at Longside. 



S. minimum, Fr. 93*, marshy pool at Braeside in Turriff.

 ditch in East Den, Peterhead.
