4.52 Mr. D. Don's Monograph of the Genus Saiifraga. 



acuta, apice recurvata ; caulina ima 5-ficla, superiora in- 

 divisa lanceolata, acuminata. Flores campanulati, can- 

 • didi, in restivatione cernui. Calyces pedicellique pube 

 viscida instruct! : laciniae lanceolate, trinerves, mucro- 

 natae : mucrone recurvo. Pet a la spathulata, tripliner- 

 via, apice emarginata : nervis simplicibus, strictis, vi- 

 ridibus. 



This very distinct and elegant species was first discovered by the 

 late Mr. G. Don of Forfar, on the mountains of Angusshire and 

 Aberdeenshire, where it grows on moist rocks in very elevated 

 situations. I have nlso observed it myself subsequently on hills 

 to the north of Loch-Lomond. Plants of it from that quarter 

 are now growing in the garden of my highly valued friend, Pa- 

 trick Neill, Esq., Secretary of the Wernerian Natural History 

 and Caledonian Horticultural Societies of Edinburgh. 



In concluding this Monograph, I have to make (p. 348) an 

 important alteration in the specific character of S. ligulata, 

 namely, to substitute glahris for utrinque hirsutis ; the paginae of 

 the leaves being quite smooth. A similar alteration is also ne- 

 cessary in the description of the same species.
