NOTES FROM THE HEBARIUM OF TEE PERTHSHIRE 

 NATURAL HISTORY MUSEUM. 



By F. BUCHANAN WHITE, M.D. F.L.S. 



IN studying the plants of Perthshire, and comparing them with 

 specimensfrom other sources, and with the descriptions in various 

 British and European Floras, I have come across a few varieties 

 either not recorded for Britain, or, apparently, altogether unde- 

 scribed. These, of course, will be duly noticed in the Flora of 

 Perthshire ; but in the meantime, it seems desirable to direct the 

 attention of other students of Scottish botany to them in order that 

 their distribution may be observed. 



Apropos of the Flora of Perthshire, it is hoped that publication 

 will not be delayed much longer ; but, since of late years every 

 season has brought to light some species unrecorded for the 

 county — the field being so wide, and the workers so few — 

 nothing has been lost, and a good deal has been gained by the 

 delay. 



Ranunculus Flammula L. Specimens accidentally grow- 

 ing in four feet of water — accidentally, since part of the bank 

 seems to have fallen into the water — had the leaf stalks very long? 

 and the blades short, and in the. lower leaves very broad in propor- 

 tion, thus: — Stalk, 3^ inches long; blade, 1 inch long ^-^ inch 

 broad. This alteration in the form of the leaves seems interesting, 

 in view of Mr. F. C. S. Roper's observations (Linn. Soc. Journ., 

 xxi., p. 380) on the submerged leaves of Ranunculus Lingua. In 

 these submerged leaves, which, however, Mr Roper considers 

 modifications of the aerial leaves, the lengthening of the stalk and 

 the widening and shortening of the blade is very marked. 



Nasturtium palustre D.C. Most of our specimens hav e 

 deeply pinnatifid leaves, with the segments dentate, and the 

 terminal one usually larger, and always so in the lower leaves. 

 These are probably var. pinnatifidum Tanoch. 

 Cardamine flexuosa with 



a. genuina G. and Gr., Fl. de France. Upper leaves with 

 oblong leaflets, almost or quite entire. 



b. umbrosa G. and Gr., Fl. de France. Leaflets, even the 

 upper, broadly oval, angular or incised. Plant branchy, diffuse.
