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 distributed 

 over all the uncultivated ground. Osmunda regalis grows plen- 

 tifully 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 re- 

 ject the fronds of this species ; those at Forked Ponds are annu- 

 ally 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. Ophio- 

 glossum vulgatum appears to be equally scarce ; a small patch 

 occurs in the Compton chalk- quarries : a closer investigation on 

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

 abundantly. Ceterach officinarum has been found very sparingly 

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

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

 on a wall at the Dairy Farm towards Farley Hill : with the ex- 

 ception of the station at Haslemere, noticed in Phytol. i. 1110, 

 no other locality in this county has been recorded for this plant. 

 Lycopodium clavatum is in great plenty on Highdown Heath, 

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

 curs abundantly in all the wet parts of the different commons. 

 Equisetum Telmateia is generally distributed in the wet parts of 

 the hills; it is abundant upon the hedge-banks against Busbridge 

 Park, in the direction of Tewsley : whilst E. arvense appears to 

 be more generally 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. fluviatile 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. sylvaticum : this species I noticed for the first time
