POLYSTICHUM ANGULARE. 183 



in the centre than at the base, and at a third below the apex, 

 the apex itself ending abruptly. Length of pinnee — two 

 inches below the apex as much as one inch and a half in 

 length, one inch below the apex only three quarters of an 

 inch, three inches below apex one inch and three quarters 

 long, four inches below apex two inches and a half long, six 

 inches below two inches and a quarter long, seven inches from 

 apex two inclies long, ten inches from apex one inch and a 

 half long, eleven inches from apex two inches and a half long, 

 twelve inches from apex thi'ee inches long; basal pair of pinnae 

 one inch and a quarter, next pair only three quarters of an 

 inch, the remainder about half an inch. The upper two thirds 

 of the frond copiously fertile. Since writing the account of this 

 Fern on page 106, I have received additional fronds, and 

 therefore add the above. 



AcuTO-GRACiLE. — Mr. Padley has sent me a long narrow 

 form with the pinnse distant and ascending; too near to be 

 otherwise named, but a very nice Fern. 



Acuminatum, Moore. — Since writing the account of this 

 Fern, I have received fronds from Mr. El worthy. His plant 

 has grown considerably since it has been named by Mr. 

 Moore, and, at the same time, grown even more characteristic 

 of its name. The fronds are nearly three feet long, and six 

 or seven inches broad in the widest part; flexuose near the 

 apex. Pinnae ascending and flexuose, somewhat distant, towards 

 the apex bundled together, on account of their perpendicular 

 growth; pinnae from two to three inches in length, being 

 crowded together in a width of from one half to three quarters 

 of an inch. Pinnae long and narrow. Pinnules remote below, 

 and less so above, narrow, long, ascending, and acutely in- 

 cised, with an acute auricle, abundantly hirsute. The upper 

 two thirds of frond copiously soriferous.
