sparingly in other situations. Scolopendrium vulgare will be found 

 in the greatest exuberance in the dingle towards Hurtmore, where the 

 variety with nuiltifid fronds frequently occurs. Blechnum boreale is 

 a common plant upon the barren heaths, preferring the sides of the 

 moist ditches. Highdown Heath and Witley Common will afford 

 this plant in the greatest perfection. Pteris aquilina is generally dis- 

 tributed over all the uncultivated ground. Osmunda regalis grows 

 plentifully by the side of Forked Pond next Thursley Common, and 

 sparingly upon Hambledon and Highdown Heaths : but to see it in 

 perfection, the admirer of this elegant species must visit the Devil's 

 Punchbowl, where the fronds attain a great height, and will convey 

 the idea of a truly royal fern. Cattle do not reject the fronds of this 

 species ; those at Forked Ponds are annually eaten off by the stock. 

 Botrychium Lunaria is evidently a rare species in this neighbourhood. 

 During the summer of 1840, I found three plants opposite Pleck Pond 

 on Highdown Heath, since which I have not seen a single specimen 

 growing. Ophioglossum vulgatum appears to be equally as scarce ; a 

 small patch occurs in the Compton chalk-quarries : a closer investi- 

 gation on the north side of the Hog's Back will probably yield this 

 plant abundantly. Ceterach officinarum has been found very sparing- 

 ly in two situations ; my friend Mr. H. Bull first noticed it on West- 

 brook garden-wall, and a few days subsequently I discovered it on a 

 w^all at Catteshall Farm : with the exception of the station at Hasle- 

 mere, noticed in Phytol. i. 1110, no other locality in this county has 

 been recorded for this plant. 



Lycopodium clavatum is in great plenty on High-down heath, L. 

 Selago very sparingly in the same locality, L. inundatum occurs abun- 

 dantly in all the wet parts of the different commons. Equisetum Tel- 

 mateia is generally distributed in the wet parts of the hills; it is 

 abundant upon the hedge-banks against Busbridge Park, in the 

 direction of Tuesley: whilst E. arvense appears to be more gene- 

 rally located higher up in the corn-fields which are inclined to be 

 rather springy. E. palustre, in marshy meadows. At the back of 

 Shalford, this species occurs abundantly in a wet meadow. E. flu- 

 viatile is in most of the ditches, and will be found in the greatest 

 perfection at Hurtmore Bottom, where the turf for fuel has been 

 dug, also at New Pond, and one of the Hammer Ponds. E. sylvati- 

 cum : this species I noticed for the first time last summer in a wood 

 near Burgate, on the weald clay.
