70 ASPIDIUM ANGULARE. 



16. — Tripinnatum, Moore. The present Fern the author re- 

 ceived as a seedling plant from Mr. R. T. Millet^ of Penzance. 

 Mr. Moore, in his "Nature-printed Ferns," says of it, "This 

 very beautiful and peculiar variety has been called Tripinnatum, 

 in contrast with the Suhtripinnatum, in consequence of its 

 basal anterior pinnules being much more distinctly pinnate, 

 though the plant is on the whole less divided than the Devon 

 form of the variety Proliferum, or the Irish variety Decompositum. 

 The most remarkable peculiarity is the unusual elongation of 

 the anterior basal pinnules, and their truly pinnate character; 

 the little pinnulets being distinctly stalked. The other pinnules 

 are highly developed, though less so than the basal one, and 

 they are crowded and imbricated. It is profuse in the production 

 of sori, and thickly covered with subulate scales. It was found 

 in Cornwall by Mr. Millet, and was first made known to cul- 

 tivators by Mr. E. J. Lowe. It is a very marked aberration 

 from the normal form, and appears to be very rare." Another 

 character of this Fern, not visible in a dried frond forwarded 

 to Mr. Moore, is strikingly exhibited in the growing plant; 

 the pinnse, instead of being flat, and lying in the same plane 

 with the stipes and rachis, are almost at right-angles to this 

 line, lying in a horizontal position above each other, — Plate

17. — Decompositum, Moore. This beautiful variety is by far 

 the most compound or divided form. An Irish Fern, cultivated 

 in the Glasnevin Botanic Gardens. 



For a more lengthy description the reader is referred to 

 Mr. Moore's "Nature-printed Ferns." 



I have procured this species wild at Matlock; Chaigeley, 

 Lancashire; and at Ambleside. For plants from Cornwall I 

 am indebted to Mr. P. T. Millett, of Penzance. Sir Oswald 

 Mosley, Bart., has sent me specimens of several varieties; Mr. 

 P. T. Millett the beautiful variety Tripinnatum, (of which a 

 coloured plate is here given;) Messrs. Pollisson the variety 

 Proliferum. For fronds I am indebted to Mrs. Delves, of Tun- 

 bridge Wells; Messrs. Pollisson, of Tooting; Sir Oswald Mosley; 

 Mr. Sim, of Foot's Cray; and Mr. Norman, of Hull. 



This species can be procured of any Nurseryman. The 

 following varieties are in the aftermentioned Catalogues: —
