SupRASORiFERUM, Wollqston, 3IS. (Fig. 35.) — Found in 

 1861, near Woolbediug, Sussex, by Mr. G. B. WoUaston. The 

 fronds are linear-lanceolate; the lobes denticulate and submar- 

 ginate. (Sub used in the sense of hardly or scarcely/, analogous 

 to submarginatum in Scolopendrium?) The lower lobes have a 

 tendency to be auricled. Suprasoriferous, as well as on the under 

 side; the name being given by Mr. Wollaston on account of 

 the sori on the upper surface of the frond. The upper sori 

 marginal. A narrow-fronded and distinct variety. 



Thompsonii, Monkman, MS. (Fig. 36.) — Found at Mulgrave 

 Woods, near Whitby, in 1859, by Mr. George Thompson, of 

 Darlington. A dwarf, almost imbricate, erect-growing form. 

 Quite constant in cultivation.
