not so narrow in proportion to their length as Beck describes, 

 varying, in a series of examples collected in one place, from only 

 a little longer than broad to about twice as long as broad. The 

 leaves also vary, in some plants being almost entire, though slightly 

 undulate, and in others being distinctly crenate. It is very desir- 

 able that our small alpine Galtha should be compared with authentic 

 specimens of C. membranacea. 



A special look-out should be kept for Calthas which root at the 

 joints. C. radicans (re-discovered a few years ago by Mr. Graham 

 in Forfarshire), is well marked by the shape of its leaves. It 

 ought to occur elsewhere than near Rescobie. The Finmark 

 plant, which has been supposed to be the same as the Scottish, 

 seems to be distinct from C. radicans Forst, and to be the same 

 as C. palustris, var. zetlandica Beeby (see Scottish Naturalist for 

 January, 1887, p. 21). It would appear, therefore, that there is 

 more than one Caltha with rooting stems. 



In conclusion, I may say that, as it is evident that more atten- 

 tion must be given to the shape of the ripe follicles, and as, un- 

 fortunately, these are not always to be found, plants which seem 

 to merit observation should be taken home and grown. Though 

 they grow naturally in wet places, Calthas are very amenable to 

 cultivation in dry ground, and hence " no difficulty should be 

 experienced in subjecting doubtful specimens to a thorough 

 investigation. 



ADDITIONAL RECOKDS OF SCOTCH PLANTS FOE THE YEAR 



1886. 



By Arthur Bennett. F.L.S. 



FOLLOWING up the records given in the Scottish Naturalist, 

 in 1886, I here purpose to enumerate those that have been 

 made during 1886. 



They include an addition to our Flora viz., Triticum violaceum, 

 Horn., and two or three plants not hitherto certain for Scotland, 

 e.g., Linum perenne, Euphorbia Paralias, &c. Numerous varietal 

 forms have been recorded for the first time as Scotch in papers by 

 Dr. Buchanan White and by Mr. Beeby in the last volume of this
