278 THE NATURALIST. 



P. aculeatum, Roth. (Polypodium, L., Aspidium, Sm.) Dr. Carrington 

 found the variety lonchitidioides, M.,- on Malham Moor. After culti- 

 vating it for some years I have no doubt whatever that its peculiari- 

 ties are variable ; I believe they are ultimately evanescent. 



Lastrea montana, Moore. {L. Oreopteris, Bory, Aspidium, Sm., Polypodium 

 Thelypteris, Huds., Hemestheum, Newm.) Not uncommon up to about 

 400 yards ! 80. 



L. Filix-mas, Presl. {Polypodium, L.) Mr. T. Stansfield mentions a 

 vai'iety ramosum (sic) found on Malham Moor, by Mr. A. Stansfield. 



L. rigida, Presl. (Lophodium, Newm.) Malham Moor, J. Nowell. 3. 



L. dllatata, Presl. The var. nana found long ago a few miles off, by Mr. 

 Tatham, may be expected at Malham, though I cannot find that it 

 has yet been seen there. 

 Var. collina, (Newm.) Not uncommon on the scars about Malham. 



Asplenium viride, Huds. [A. Trichomanes ramosum, L.) Rocks and walls 

 about Malham, frequent ! A common fern on the Craven limestone. 

 In the adjoining valley of Wharfe this fern is still oftener seen than 

 in Airedale and Ribblesdale. The crevices of the limestone wall, on 

 the left hand of the little road from Kilnsey to Arnclifi'e, contain 

 multitudes of plants, together with A. TrichomaneSj A. Ruta-muraria, 

 and Cystopteris fragilis. 25. 



Var. multifidum, M. Above Malham Cove, very plentiful, T. Stans- 

 field ! 



A. TricJiomanes, L. This fern is perhaps the very commonest of all in the 

 neighbourhood of Malham. 81. 



In 1863 I found two or three plants on the Kilnsey side of Malham 

 Moor, which are authenticated as var. incisum. This tolerably distinct 

 variety is not so rare as the books give it ; at least several new stations 

 are being found every year. 



Var. suhcequale, M. About Malham, A. Stansfield. 



* A singularly barbarous and unpleasing name, which is continually mispro- 

 nounced, and -which few printers will spell correctly. As an affair of Greek, 

 lonchiteides (or even ides) would be better, besides being more easily written and 

 read. I mean always to spell it so in future. Selaginoides, ornithoj^odioides, 

 hieracioides, amygdaloides, and a crowd of others are equally wrong and want 

 altering. It may be as well to remind the makers of specific names that the 

 Greeks, whom they profess to follow, added etS?;? [eides, and not oides) to the 

 root of the word. I shall perhaps have something to say on this and other 

 points of botanical nomenclature by and by.
