208. Inland Localities for Maritime Plants. I beg to hand you the following no- 

 tice of plants which have been recently discovered by Mr. George Reece of this city, 

 in localities not hitherto noticed by botanists, so far as I am aware. Arenaria marina 

 is mentioned in Purton's 'Midland Flora' as occurring on Defford Common, where 

 salt springs were discovered many years since, and where salt is now, I believe, manu- 

 factured an a small scale. Erodiura maritiraum is also recorded by Purton as having 

 been found at Stourbridge, Kinver and Bewdley ; and to Triglochin palustre is as- 

 signed a habitat at Feckenham ; but neither Glaux maritima nor Plantago maritima 

 is noticed in the ' Midland Flora.' Arenaria marina, Glaux maritima and Triglochin 

 palustre are found on the banks of the Droitwich Canal ; Erodium maritimum and 

 Plantago maritima on Hartlebury Common. Beautiful specimens of these plants have 

 been collected by Mr. Reece, and are now deposited in the herbarium of the Worces- 

 tershire Natural-History Society. — /. Evans; Grove House, Worcester, August 8, 1842. 



209. Note on Woodsia Ilvensis. On the 17th of 8th month [August] 1798, my fa- 

 ther gathered a single frond of a fern from Crosby-Ravensworth Church, Westmore- 

 land. Being unable to name it he showed it to several botanists in London, who coiUd 

 not decide what it was ; Lewis Dillwyn at length sent it to Sir J. E. Smith, who re- 

 turned the specimen labelled as follows : — 



" Polypodium arvonicum. 



With, et Fl. Brit. J. E. Smith. 

 P. ilvense. With. ^ 

 Acrost. ilvense, Huds. 



(not Linn.) 

 Acr. alpinum, Bolt." 

 The original specimen is now in my possession, with Sir J. E. Smith's autograph ; the 

 frond is 3^ inches in length from the bottom of the rachis to the apex, and about 2 

 inches from the lowest pinnae to the apex. The church has been pulled down and re- 

 built within the last few years. — Silvanus Thompson «• Friends' School, York, 8lh

210. Enquiry respecting the British Oaks. Can any of your correspondents inform 

 me what are the true specific distinctions between Quercus Robur, intermedia, and 

 sessiliflora? I have found what I consider to be the three species growing in various 

 localities round Manchester: I have also gathered a number of specimens with the 

 form of the leaves, length of the petioles and situation of the fruit so varied and inter- 

 mediate, that I cannot with certainty refer them to either species. Several trees near 

 Mottram, from which I procured specimens last month, have the fruit quite sessile and 

 the petioles of the leaves so short as to be scarcely perceptible ; whilst specimens of the 

 ti*ue sessiliflora from Leigh Woods, near Bristol, given to me by Mr. Grindon, and al- 

 so specimens gathered by myself in Bredbury Wood, Cheshire, have petioles near an 

 inch in length. I have also specimens from near Mottram, which appear to be hy- 

 brids between Q. Robur and intermedia ; these have their fruit upon peduncles less 

 than an inch long, but never properly sessile, whilst the leaves are perfectly so. The 

 fonn which I consider to be the real intermedia of authors, has long petioles to the 

 leaves, and peduncles nearly half an inch in length, but one of the most prominent 

 characters is in the form of the foliage ; for whilst in Robur the leaf is much dilated 

 towards the extremity, in intermedia the greatest width exists near the centre, the end
