56 SHORT NOTES. 



following general custom, writes, " Benth. PI. Hartw. 108. " When 

 a plate is cited, it is usually as " t." Moreover, what Prof. Greene 

 calls the " preface " is an introduction of twenty pages, in which 

 the plants figured are discussed, and the last eleven of which are 

 styled " Declaratio Tabulae." A further inconvenience is caused by 

 the fact that Prof. Greene's " 17 " refers, not to the order of plates, 

 but to that of figures, the plate being the 13th. When MS. numbers 

 are supplied, either of plates or figures, they should be placed in 

 square brackets : we think the former, not the latter, should be 

 numbered. Had Prof. Greene written " [t. 13 lower fig.] " or even 

 " [fig. 17] ," his meaning would have been clear : but " Bivinus, 

 Tetrap. 17 " naturally bears the interpretation which we placed upon 

 it. — Ed. Journ. Bot.] 



Mosses of North-east of Ireland. — A note by Mr. H. N. Dixon 

 having reference to the mosses of the north of Ireland, which 

 appeared in Journ. Bot. 1891, p. 359, and another by Mr. H. G. 

 Hart in your last issue, are somewhat misleading, and seem to 

 require a brief notice by me. Mr. Dixon, after an interesting list 

 of mosses which he collected during a short trip to Donegal, gives 

 what purports to be a list of mosses not mentioned in the Flora of 

 the North-east of Ireland, but which were found by him on the 

 Antrim coast. This list, however, when examined, melts down to 

 one species certain, Grimmia Hartmajiui, and one uncertain, Campy- 

 lopus SchimperL Amongst plants selected, ''on account of their 

 apparent rarity," for special record with the two above mentioned, 

 one would scarcely expect to find, among others, such names as 

 Dicranella cervicidata and Dicranum pellncidum. Mr. Hart refers me 

 to a list of Irish mosses collected by himself, and published in Journ. 

 Bot. for 1886. These records he imagines were overlooked in the 



compilation of the Flora of the North-east of Ireland. Such, how- 

 ever, was not the case. Mr. Hart's list has just three references to 



the North-east: — No. 1. Trichostomam littorale (Mollia littoralis) is 

 duly recorded in Flora, p. 215. No. 2. Ditrichium homomallum is 

 an error on Mr. Hart's part ; Carlingford Mountains are not in Co. 

 Down, as he states, but in Co. Louth, and therefore not in the 

 North-east of Ireland. No. 3. Plagiothecium elegans [Borreri) was 

 found in Mourne Mountains by several collectors prior to Mr. Hart's 

 visit. Their better localised notes were used, and his was un- 

 necessary. — S. A. Stewart. 



Galium sylvestre in Berks. — Last August, Mr. F. Tufnail, of 

 Reading, was fortunate enough to meet with the above plant on a 

 chalky slope beneath Suleham Woods, near Pangbourne. I have 

 seen the plant growing there, and am inclined to believe it to be 

 native. The same slope, although not at this precise spot, it is 

 true, is a habitat for Euj>horbia Cyparissias, which is not usually 

 considered to be native, and a few larches have been planted in the 

 vicinity ; but the Galium occurs not with or near these, but with 

 purely native plants, such as Gentiana Amarella, Galium Molluyo 

 var. insubriciun, Asperula cynanchica, Campanula glomerata, Ciiscuta 



Epithymum, &c. It is not what we are accustomed to call the type 

 plant, but the variety with narrow, hairy leaves, to which in
