main river or East Yar ; as, near Alverstone above the mill; in Alverstone 
Lynch; at Knighton; at Newchurch; and Merry Gardens. Along the 
Medina it abounds in the wettest parts of the Wilderness, and in a 
boggy meadow at Cridmore. There are besides two outlying stations ; 
one a Willow thicket north-east of Compton Grange; the other in the 
marsh at Haton Freshwater Gate, where it is plentiful. 
Lastrea Oreopteris (Sweet Mountain Fern) is very rare, if not 
extinct. America Woods (Apse Castle) near Shanklin, and a low wet 
bank at Guilford are the only ascertained stations; in both it has been 
lately sought unsuccessfully. 
1. Fihx-mas (male Fern) is plentiful; the variety with incised and 
sometimes elongated pinnules is not rare in shady woods; the variety 
palacea or Borreri, with abundant ruddy scales on the stipes, occurs in 
many places, especially upon peaty soil. 
LL. spinosa is not common; but will be found to inhabit most of the 
boggy Willow thickets, &c., often in company with L. Thelypteris. 
Li. dilatata occurs wherever there is a bog, and also on the shady 
banks of deep-cut lanes. 
Asplenium Adiantum-nigrum (Black Spleenwort) is common through- 
out the sandy district; but is more sparingly distributed elsewhere. 
A. Trichomanes (Common Spleenwort) is rare. The rocks in the 
Undercliff; West Cowes; Quarr Abbey; Carisbrook Castle; Chale 
and Shorwell, are the principal localities. I have more than once heard 
the name of ‘‘ Maidenhair”’ applied in mistake to this species.. 
A. marinum (Sea Spleenwort) used formerly to grow in very small 
quantity upon some rocks at Niton, but it is believed to have been 
completely eradicated. 
A, Ruta-muraria (Wall Rue) is rare. Ryde; Arreton Church ; 
East Cowes; Calbourne, and Freshwater churches, are the localities 
where it has been found. | 
Athyrium Fihx-foemina (Lady Fern) with most of its varieties, is 
abundant wherever the soil is boggy. 
Scolopendrium vulgare (Hart’s-tongue) has been found bifid and 
multifid, crested, and crisped, &e. 
Pteris aquilina (Brake) is plentiful, especially on the heathy com- 
mons; it grows even on chalk upon the north slope of Bembridge Down. 
Blechnum boreale (Hard Fern) is local, but not of very unusual 
occurrence, chiefly in the boggy parts of the sandy district. 
Osmunda regalis (Flowering Fern) its usual companion, is the more 
generally distributed of the two; like the Blechnum, it abounds most 
along the course of the East Yar and the Medina, and other places upon 
the greensand. 
Botrychium Lunara (Moon-wort) is rather rare ; Nunwell ; Shank- 
lin; Landslip; and especially the Wilderness and Rookley, are the 
known stations, but it requires a close and careful search to find so 
small a plant. ‘ 
Ophioglossum vulgatum (Adder’s-tongue) is not very uncommon. It 
grows in several damp meadows about Bembridge ; in the Undercliff ; 
about Appuldurcombe, and in the Wilderness ; in Parkhurst Forest ; 
and in the marsh at Easton.
