and I shall be happy to communicate anything bearing on Mr. Grin-

320. Note on a Locality of Equuetmn Jiiiviatile. In my Reigate 

 Flora I have recorded a single station for this plant, " on Reigate Hill, 

 south side of the Wray lane, far from any water." This lane branches 

 off from the Brighton road through Croydon and Reigate, at the turn- 

 pike-gate on Wray common, perhaps a mile and a half north-east of 

 the latter town, and, after a gradual ascent in a north-westerly direc- 

 tion, joins the Brighton road through Sutton on the top of Reigate 

 hill. Many years ago, the late Alderman Waithman, who then had 

 a country house on Wray common, opened a pit close to Wray lane, 

 on its south side, for the purpose of quarrying the upper green-sand, 

 which was sent to London to be used as hearth-stone. After a short 

 time, from various causes, the quarry was abandoned, but not until a 

 high mound of loose sandy rubbish had accumulated at the entrance. 

 About the year 1836, when I visited Reigate after a few years' ab- 

 sence, I found this mound covered with a most luxuriant crop of 

 Equisetum fluviatile, looking like a fir-wood in miniature ; the plants 

 were two and three feet high. The locality is a very dry one ; the 

 nearest water is the large pond in Gatton park, and that is quite half 

 a mile distant, and considerably below the spot in point of elevation. 

 I do not remember having met with this plant in or near water, but 

 Mr. llott has recorded a locality at Norwood, where it grows on a bank 

 " and about a small pond close by," (Phytol. 295). — Geo. Luxford ;

821. On the arrangement of a Herbarium. Excellent as my friend 

 Mr. King may find his plan for the arrangement of a herbarium (Phy- 

 tol. 585), prejudice in favour of a different one makes me think it open 

 to one or two objections; and as it is highly desirable that a collec- 

 tion should be commenced upon a good system, inasmuch as chang- 

 ing it afterwards is attended with much inconvenience, allow me to 

 suggest the following plan to your correspondent. Let every species 

 have a separate folded sheet of white paper, and each genus a sheet 

 of folded blue,* placing the former inside the latter, hke drawings in 

 a portfolio, all the creases or folds of the sheets being to the left hand. 

 The name of the genus should be written on a slip of white paper, 

 and pasted near the fold of the sheet, at equal distance from top and 



* The exact size is immaterial, but it should not be smaller than foolscap nor lar- 

 ger than double folio post, which is ample, under skilful management, for any plant, 

 to say nothing of the expense and unwieldiness of very large paper.
