170 OBSERVATIONS ON THALICTRUM MINUS. [AuffUSt, 



fields. The British specimens preserved in my collection are 

 from the following localities^ \dz. : — Perthshire : banks of Loch 

 Tay, Mr. Scott. Fifeshire : North Queensferry^ John T. Syme. 

 Dumfriesshire : banks of the Nith, near Dumfries, Mr. Cruick- 

 shanks. Lake District : shores of Ulswater, and several other 

 places, D. Oliver, etc, Durham: about the Tees in several 

 places, Yorkshire : by the Tees at Holwick, and lower down, 

 and on the south side of the Wharfe at Thorp Arch. Doubtless 

 this is the plant which most of the stations, recorded for T. 

 majus, produce: the stem attains a height of from 1| to 3 feet, 

 and is erect or suberect in habit, firm, usually glabrous, mode- 

 rately flexuose, and prominently striated; the leaves descend to 

 the base of the stem, and ascend amongst the lower branches of 

 the panicle ; the lower leaves are large, broad, and wide-spread- 

 ing, their segments blunt, pointed, and often heart-shaped at the 

 base ; the auricles of the lower stipules embrace the stem, those of 

 the upper, spread as in the preceding ; the panicle is ample, and 

 much elongated, the lower branches moderately flexuose, spread- 

 ing from the stem at an angle of about forty-five degrees ; the 

 carpels are more oblique, broader below, and much smaller than 

 in the preceding. 



The only British stations for T. eminens with which I am ac- 

 quainted, are both in West Yorkshire : Malham Cove, in the val- 

 ley of the Aire, and Bolton Woods, in the valley of the Wharfe. 

 This species much resembles T. flexuosum in habit of growth, 

 but may be known by the following characters : — The stem is 

 more slender, and somewhat shorter; the leaves are smaller in 

 general outline, not ascending so much into the panicle as in the 

 other, and their segments are narroAver and sharper ; the branches 

 of the panicle are unusually flexuose, peculiarly irregular, diffuse, 

 and few-flowered ; the pedicels are arched at flowering-time ; the 

 carpels are equally compressed and oblique, but rather smaller 

 and narrower. 



T. calcareum was found several years ago by Mr. Ball, on Ben 

 Bulben, in Sligo [vide Bot. Gazette), and the specimens of that 

 gentleman were seen and authenticated by M. Jordan. To the 

 courtesy of Mr, G, S. Brady I have been indebted for a speci- 

 men of the Ben Bulben plant ; and have what appears to be the 

 same, from Honister Crag, in Cumberland (coll, D. Oliver) ; 

 Malham Cove^ West Yorkshire (J. Dugdale) ; and also from
