any locality. No specimens of the Hard Prickly Shield 

 were found. 



Two separate colonies of another fern were found in a 

 wood on a hillside, which I scarcely hesitate to label 

 Lastrea Montana. Still, dogmatism is often associated 

 with ignorance, and I must allow for mistakes. 



Cystoptevis fvagilis grows abundantly about the woods 

 and streams, and requires no special comment. I was 

 specially pleased to find the beautiful Oak Fern growing 

 in considerable numbers. When growing under favour- 

 able conditions — as in my little shady " Fern Valley," as 

 I used to call one of my favourite haunts — it attains the 

 height of one foot or so. 



I was surprised to find no specimens of our friend 

 Scolopendvium. Indeed, two or three plants on a rockery 

 in our Park were all I ever saw in Serbia, but I have little 

 doubt that it occurs. 



The genus Asplenmm is well represented. Adiantnm 

 nigrum is the commonest of the Spleenworts, and occurs 

 everywhere. A. trichomanes is rather less frequent, but 

 there is plenty of it. On the barren rocky places I have 

 found a good deal of A. septentvionale. In similar places 

 one sees an occasional plant of what must be A . gernianicum, 

 though this species is only familiar to me as a text-book 

 subject. 



I had almost forgotten Polypodium vulgare, the common 

 polypody, but by no means as common in Serbia as one 

 might have expected. Some of the specimens attained a 

 large size, but no variation of any interest was observed. 



On an old ruined wall in the famous Kraljevo Monastery, 

 I found two other British species that I had not previously 

 encountered. These were two other Spleenworts — A. 

 vuta-muvavia and A, ceterach — both occurring as quite 

 young specimens. 



Two young plants, which might afterwards have
