BRITISH FERNS 



Tripinnatum (acurodes) (Plate XXXI). — Found by Mr. E. J. 

 Lowe in a batch of normal seedlings sent from Cornwall ; it is 

 described as of erect habit, with the pinna; set on horizontally like 

 the steps of a ladder. As the name indicates, the pinnules are sub- 

 divided into pinnulets constituting a tripinnate or thrice-divided 

 form. 



T. Gillett (see Appendix No. LXXYII). — Found near Yeovil; 

 a very fine form indeed. 



T. Millett, T. Padley. — Similar to those above described, but 

 distinct. 



Truncatum (Plate XXX). — Found in Ireland ; fronds and pinna? 

 terminate squarely and abruptly, the fronds being thus reduced in 

 width and length 



Figs. 251, 252. P. mix. veslilitm. A, apex showing bulbil ; B, middle pinna. 



Vestitum (Figs. 251 and 252).— Found in N. Devon by Rev. 

 C. Padley ; peculiarly fertile and distinguished by the fronds bear- 

 ing a terminal bulbil resembling an exotic form.
