everything is in its place, the top waddings, which should have 

 been hung up and will have become quite dry, should be put 

 on again, the plants returned to the press, and the same opera- 

 tion every day until perfectly dry. By this means the plants 

 will be found to retain their colours wonderfully ; care, however, 

 must be taken to ensure their being perfectly dry before being 

 placed in the herbarium ; and for this purpose it is as well to 

 leave them in their drying papers without the waddings for a 

 few days before doing so. As rapidity in drying is the great 

 object, a chamber with a glazed roof, such as used by photo- 

 graphers, would facilitate matters greatly ; it is hardly necessary 

 to say that the herbarium itself cannot be kept in too dry a 

 place, as many plants are very evanescent in their colours even 

 years afterwards, should they come in contact with any damp. 

 I may add that the drying papers after use should be placed 

 themselves under a heavy weight, being slightly damped before 

 doing so, when they will be as good as new ; and the same 

 paper and the same cotton will last for many years, and after 

 the first outlay there will be no further expense. 

 Seggieden, by Perth. 



Conyza squarrosa near Perth.— A specimen of this plant, found near 

 Perth in an apparently wild state was recently brought to me to name by Mr. 

 J. M'Millan.— John Sim, Bridgend, Perth, August, 1872. 



Kecent additions to the Flora of the North-East of Scotland.— 



The following notice of a few of the plants recently found in this district may 

 be interesting to some of the readers of the " Scottish Naturalist " ; — Ranun- 

 culus heterophyllus Sibth. ; R. circinatus Sibth. ; R. fluitans Lam. ; Draba 

 brachycarpa Jordan ; Viola Reichenbachiana Boreau ; Sagina ciliata Fr. ; 

 Cerastium trivialc var. alpinum Koch. ; Ulex Gallii Planch ; Lathyrus 

 ■maritimus Big. ; Torilis nodosa Gaert. ; Senecio viscosus L. ; Thrincia hirta 

 DC; Hieracium dubium Fr. ; Centunculus minimus L. ; Orchis ificarnatah.; 

 Neottia Nidus-avis Rich. ; Corallorrhiza innata R. Br. ; Potamogeton nitens 

 Weber ; Carex Watsoni Syme ; C. Kochiana DC. ; Sctaria verticillata 

 Beauv. (introduced) ; Aira uliginosaWelhe ; Polypodium Robertianum Hoffm.; 

 Asplenium obtusum Willd. ; Lycopodium inundatum L. The additions to 

 mosses, &c, are too numerous for a short notice.— John Roy, Aberdeen. 



Occurrence of Anacalypta latifolia Furnr. in Perthshire.— Perthshire 

 muscologists will be glad to know that Professor Barker gathered this rare and 

 beautiful moss in Glen Tilt, in July last. It was previously known in Braemar 

 and Clova ; this is, therefore, its third British station. — Id. 



Double Flower?.— During the summer I observed the following plants with 

 double Jlowers (Jlore plenoj : — Cardaminc pratensis L. ; Lepidium smithii 

 Hook ; and Veronica saxatilis L. Possibly this state may not be uncommon, 

 but I have not seen it in these plants before.— Id.
