specimens for examination. Specimens of the timber of W ellingtonia 

 gig ant ea presented under the microscope a double row of opposite 

 disks, which, as well as their central dot, were elliptical. 



6. "On Ophioglossum lusitayiicvm, Linnaeus," by Thomas Moore, 

 F.L.S. The author remarked that the discovery of the Ophioglossum 

 lusitamcum,Li.y within the politico-geographical limits of Great Britain, 

 so soon after that of the Gymnogramma leptophylla, another S. Eu- 

 ropean fern, is a fact of much interest ; and thought that a short account 

 of the plant drawn up from fresh Guernsey specimens might be of some 

 interest to those who are studying either our native Ferns or our 

 native flora.

Note on the Vegetation of Mount Argceus in Cappadocta, ^ Y 



By M. P. DE TCHIHATCHEFF. ^I*! f 



As Mount Argseus, of which I have ascertained the height to be 

 384 1 metres above the level of the sea, consists of a certain number 

 of plateaux, forming so many terraces arranged one above another, 

 with intervening slopes of greater or less abruptness, the study of 

 the most characteristic vegetable forms of these plateaux may fur- 

 nish an approximative idea of the vegetable physiognomy of the 

 giant of Asia Minor, which had not been visited by any botanist until 

 I ascended it in August 1848. Amongst these plateaux, of which I 

 have indicated the respective positions in my work on the * Geo- 

 graphic physique de I'Asie Mineure,' the most considerable are, that 

 of Tekir, situated on the eastern side of the mountain, at an altitude 

 of 2128 metres, and the three plateaux arranged in steps on its 

 southern face, by which one ascends from the plain of Everek to the 

 summit of the mountain. These plateaux may be designated by the 

 following names, rising from the bottom upwards : the basaltic pla- 

 teau, placed immediately above the plain of Everek, which consti- 

 tutes the southern foot of the mountain ; the lower plateau ; and 

 lastly, the upper plateau, which leads to the central cone, crowned by 

 the crater, which is surrounded on the south side by a barrier of 

 inaccessible trachytic rocks. 



The great number of limpid streams which water the surface of 

 the Tekir plateau, maintain a pretty good vegetation in that locality. 

 Amongst the plants in flower on the 1 7th of August, I observed, 

 Oxyria reniformis, R. Br. sp., Carduo dejlorato aff., L., Podosper- 

 mwn intermedium, Solidago Virgaurea, L., Chamcemelum oreades, 

 Boiss., Helichrysum globiferum, Boiss., Andrachne telephio'ides, L., 

 Lamium armenium, Boiss., Silene argcea, n. sp., Phyteuma linifo- 

 limn, Boiss., Pulsatilla alhana, Stev., Sibbaldia parvifolia, Willd., 

 &c. ; as well as some species of Asperula, Odontites and Androsace, 

 which were less characteristic. 



The basaltic plateau, the dry poor soil of which is strewed with 

 blocks of stone and pierced by projecting rocks, is only covered with
