NOTES ON MID-PERTH PLANTS 195 



■'~L. minor Desf. As a casual at North Lodge, Duncrub, 1910, 

 1911. 



Scrophularia vernalis L. Abundant on a sunk wall near 

 Duncrub. 



Mimulus Langsdorffii Donn. Sparsely distributed along 

 Dunning Burn ; plentiful in a marsh south of the village. 



Utricularia vulgaris L. " Whitemoss, Dunning (!)." I have 

 not succeeded in finding this plant in the loch, but as I have been 

 limited to hand-dredging I am not in a position to say that it has 

 here become extinct ; yet I shall not be surprised if this proves 

 true, judging from the abundance of Elodea and Myriophyllum in 

 the loch. 



Lamium maculatum L. At Jockslodge. 



Plantago media L. On lawns at Duncrub, almost certainly 

 introduced with grass seed. 



Polygonum Bistorta L. Given only for "Forth" area in 

 Fl. Perthsh. "Naturalized in a few places in some of the other 

 districts, but not common." Well established near Millhaugh 

 and at St. Andrews. 



Humulus Lupulus L. Several plants in the hedge by Station 

 Eoad ; a relic of cultivation. 



Elodea canadensis Michx. Plentiful in Whitemoss Loch. 



Polygonatum multiflorum All. Monhook Wood ; Sawmill Wood ; 

 Duncrub, not abundant. 



*Muscari racemosum Lam. & DC. At Duncrub ; no doubt a 

 relic of cultivation. 



■'Ornithogalum umbellatum L. Sawmill Wood; Duncrub. 

 Fairly plentiful at both places. 



Arum maculatum L. A naturalized alien in Perthshire. Abun- 

 dant in Sawmill Wood. 



Alisma ranunculoides L. " Loch west of Dunning (Arnott in 

 Fl. Scot. 1821). No recent record." I have specimens gathered 

 in 1908. The plant still grows at this station (no doubt the 

 Whitemoss Loch) in small quantity. I first observed the plant 

 near the south-east corner of the loch, but, owing to the over- 

 crowding of such marsh plants as Potentilla Comarum and 

 Menyanthes trifoliata, it disappeared from here and reappeared on 

 a small mud-fiat at the north-east corner, a spot which it had 

 not, to my knowledge, previously occupied. 



Potamogeton filiformis Nolte. " Whitemoss, near Dunning 

 (W. Martin) (!)." Mr. Bennett has kindly verified my gatherings, 

 and although 1 have never obtained specimens in fruit, he has 

 little doubt that the determination is correct. The plant is 

 plentiful in the loch, the only recorded station in Fl. Perthsh. for 

 the county. I do not know of any recent records. It is surprising 

 that this pondweed should be " very rare " in Perthshire, for in 

 some of the Fife lochs it abounds. 



Zannichellia pakistris L. "Whitemoss, near Dunning (!)." 

 Also " very rare " in Perthshire, So far I have failed to find the 

 plant in the Whitemoss. 



Eleocharis acicularis Roem. & Schult. " Loch west of Dunning
