Rubus Chamsemorus again observed. 



On September 6th we made a search for Rubus ChamcBmortis in its only 

 known Irish localit}', where it was rediscovered on August loth, 1892 

 [lown. Bot., 1892, p. 279, and Ii'ish Nat., 1892, p, 124). Although the exact 

 localit}', to within a few yards, was soon recognized, it was with no little 

 difficulty that a few plants were found. The first thing to attract 

 attention was a couple of leaves, withered and detached, lying on peat ; 

 subsequently others were seen here and there, and then a few green 

 leaves half concealed among the stunted heather. 



This most interesting Irish plant looks as if it were just struggling for 

 existence, and that it has borne either flower or fruit for many years 

 seems improbable. On this visit we made quite certain, from the six- 

 inch ordnance map, that both localities given in the Cybele Hibernica 

 (new edition) are considerably more than a mile from the nearest point 

 of Londonderry, and that the species is entirely confined to Co. Tyrone. 

 We cannot help thinking that a careful and minute search on the 

 highest portions of the adjoining hills in Tyrone and Derry would prove 

 that Rubus Chaincsinorus is not confined to one mountain in Tyrone. 



That the present locality is identical with the old record we have no 

 doubt, and it is curious that both in 1826 and in 1892 it was erroneously 

 believed that the localit}- where it grows was on the boundary line 

 between Derry and Tyrone. There was no six inch map in 1826, and 

 in 1892 it was unfortunately not referred to. Had it been, the plant would 

 never have been recorded as occurring in Derry, though it is quite 

 possible it may 3'et be found in that county by some keen-eyed 

 botanist. The fragments collected on this occasion have been given to 

 the Dublin Museum.

Lathyrus Aphaca at Stranmillis, Co. Antrim. 



This plant has been observed at Stranmillis from 1864 to 1872, see 

 Flora N.E.I., p. 276. Last August I came across a few plants growing 

 in a shady place in a field east of the Botanic Gardens Park, in the same 

 neighbourhood. As this ground will shortly be utilised for building 

 purposes, and is at present a play-grcund for children, I am afraid this 

 beautiful and curious Lathyrus will very soon cease to exist at this station.

Glyceria festucseformis. 



In the Journal of Botany for November, Dr. A. B. Rendle describes and 

 figures this Irish addition to the flora of the British Islands. The bulk 

 of the paper consists of extracts from Mr. Praeger's paper in the October 

 number of the Irish Naturalist*
