are situate in a wood on the left hand side of the road, and form al- 

 most a semicircle, terminating very abruptly, and being consj^icuous 

 objects wherever they are freed from the thick underwood : upon 

 these rocks flourishes, in great luxuriance, the beautiful Hjmeno- 

 phyllum Tunbridgense, covering, in some instances, the entire face of 

 the rock, but growing most vigorously in the crevices where the sun 

 never penetrates. After enjoying the delightful view from the summit 

 of the highest rocks, where we observed Vaccinium Myrtillus and 

 Convallaria majalis, in large patches, but not in flower, we turned 

 our steps towards Tilgate Forest. On reaching Turaer's Hill Gate, 

 we took the left-hand road, which, after about three miles' ride, and 

 finding Linum angustifolium in great plenty on a bank in the lane, 

 brought us to " Starve- Mouse Plain," a swamp lying between Pease 

 Pottage and the Brighton railway, where we commenced our re- 

 searches, Exacum filiforme being the chief attraction, which we soon 

 found, growing in the greatest profusion and of extraordinary size, 

 some specimens measuring five inches in height and much branched : 

 we also collected Lycopodium Selago, inundatura and clavatum, Nar- 

 thecium ossifragrum, Eleocharis multicaulis, Hypericum elodes and 

 humifusum, Scutellaria minor, Radiola Millegrana, Melica caerulea, 

 Erica Tetralix with white flowers, and the elegant Campanula hede- 

 racea, which abounds in this locality. We then returned home, well 

 pleased with our day's excursion and success, and not without the 

 hope of revisiting the same spot another year, when we trust that 

 others of our friends will join us, and participate in the enjoyment 

 of such a delightful ramble. — JV. Hanson ; Reigate, September 7, 1843. 



372. Note on Lastrica spinulosa. You are quite correct in what 

 30U say (Phytol. 719) that Aspidium spinulosum of ' English Botany ' 

 is only a young weak state of dilatatum : Mr. Mackay, who supplied 

 the very specimen there figured, assured me so years ago. — IV. T.

373. Another word on Lastrcea spinulosa. I hasten to correct an 

 error in my former communication (Phytol. 719), wherein I expressed 

 a belief that linearis is " the only distinguishing epithet the plant 

 has ever received." I have since found that Roth was well acquainted 

 with our plant, and described it very carefully under the name of Po- 

 lystichum spinosum : our Lastraea dilatata is also most elaborately 

 described SiS Polystichum mnltijlorum of the same author : the no- 

 menclature of the species will therefore require careful investigation.
