Anthyllis vulneraria L. 



Koch and Grenier and Godron recognise two forms. 



i. vulgaris Koch. Stem hairy only at the top, and with one to 



two leaves or none ; not branched. 

 2. maritima Koch. Taller ; stem with adpressed hairs through, 

 out, and with three or four leaves \ often branched, the 

 branches bearing flower heads at the ends. 

 All our specimens, though not from the neighbourhood of the 

 sea, agree with the description of the second form. 

 Spiraea Ulmaria L. 



Koch distinguishes 2, and Fries 3 varieties. Koch's var. dis- 

 color (cf which he gives S. glauca Schultz as a synonym), and 

 Fries' var. nivea are our common form with the underside of the 

 leaves tomentose. Koch's var. denudata (S. denudata Hayne) 

 seems to be the same as Fries' var. viridis, and has the underside 

 of the leaves glabrous ; but Fries mentions a var. glauca with 

 leaves glaucous below, and scarcely tomentose. At a later period 

 he seems to have considered that nivea and glauca (S. glauca 

 Schultz) were just the ordinary form, and that the only variety to be 

 retained was denudata Pressl. Whatever name it should bear (for 

 it seems also to be the var. concolor Lange) it is not very common 

 but is widely distributed in Perthshire. It is to be noted that the 

 stem leaves should be examined, for in S. ulmaria the radical 

 leaves are (always ?) glabrous below. 

 Potentilla anserina L. 



Var. sericea Koch. Leaves silvery white, with silky hairs, on 

 both sides. This is only an extreme form, and is scarcely worth 

 retaining as a variety. 

 Potentilla maeulata Pom-r. 



Variable. Most of our specimens agree with Koch's var. firma 

 (to which he refers P. sabauda D.C.), of which the characters are 

 the more stout and erect stem, the leaflets subrotund-obovate, with 

 margins overlapping a little, and the teeth broader ; but a plant 

 from Rannoch agrees pretty well with his var. debilis (P. debilis 

 Schleich), in the oblong-obovate more deeply incised leaflets, and 

 the weaker and shorter flowering stems not rising much above the 

 radical leaves. 

 Geum rivale L. 



Plants with much paler foliage and greenish-white flowers (and 

 retaining these characteristics in cultivation), occur in Glen Farg.
