dentate at their apices. The superior basal lobe much the 

 largest, and more or less divided. Hachis and secondary rachides 

 covered with long pale scales. Nearly the whole under surface 

 of the frond soriferous. Some very fine forms have been found 

 in Devonshire, by the Rev. C. Padley, of Bulwell Hall. My 

 thanks are due to ]\Ir. Swynfen Jervis, of Darleston Hall, and 

 to the Rev. C. Padley, for fronds.

Obtusissimum, Moore. (Fig. 9'7.) — Found at Ottery St. 

 Mary, Devonshire, by Mr. G. B. Wollaston, of Chiselhurst. A 

 most remarkable form, and very rare. Frond ovate-lanceolate, 

 bipinnate, the apex ending suddenly. Pinnae obtuse, crowded, 

 their apices broad-pointed. Pinnules subrotund, blunt, with 

 short spines, densely imbricate, distinctly stalked, and having 

 no auricle. Mr. Elworthy, of Nettlecombe, has sent me a frond 

 somewhat similar from a plant found by him last spring. It is 

 more elongate and narrow, has smaller and more oval pinnules, 

 and has the sori confined to the extremity of the pinnaj. I 

 have deemed it sufficiently distinct to name, and have called 

 it Extremum. My thanks are due to Mr. G. 13. A\ ollaston, of 

 Chiselhurst, and to Mr. Swynfen Jervis, of Darlaston Hall, 

 for fronds.
