with his excursions. His papers related mostly to phanerogams, 

 but in 1886 he published a list of localities for the hepatics and 

 mosses which he had collected at various times in Ireland. Some 

 of his later notes on Irish plants were printed in the Irish 

 Naturalist. His many observations on the plants of the Irish 

 mountain ranges are summed up in a paper contributed to the 

 Proceedings of the Eoyal Irish Academy in 1891. The tribute 

 paid to Hart's work in the second edition, founded on the papers 

 of his life-long friend A. G. More, of the Cybele Hihernica, by its 

 editors, Messrs. Colgan and Scully, is evidently well deserved : he 

 " has done more," they say, " to further our knowledge of Irish 

 plant distribution than any other explorer of recent times." His 

 last note in this Journal records his discovery in Skye of Arabis 

 alpina, of which Mr. Druce recently exhibited Skye specimens at 

 the Linnean Society. He died at his residence, Carrablagh, on 

 Lough Swilly, Donegal, on Aug. 7, 1908. 



But Hart's botanical work was by no means limited to these 

 islands. In 1876 he was appointed naturalist to the British 

 Polar Expedition, and his exceedingly interesting account of the 

 localities visited and of the plants collected by himself and his 

 colleagues extends throughout this Journal for 1880, its earlier 

 production having been deferred through ill-health. In 1883 he 

 took part in an expedition organized by the Palestine Exploration 

 Fund ; his report on the botany of Sinai and South Palestine is 

 published in the Transactions of the Eoyal Irish Academy, xxviii. 

 (1885), and that on the botany of the Jordan Valley and Western 

 Palestine in the Journal of the Exploration Committee for 1885 : 

 the former contained descriptions and figures of three new species, 

 and added about seventy plants to the Palestine flora. The 

 observations detailed in these two papers, with the zoological 

 results of the expedition — for Hart was also an accomplished 

 zoologist, although his work in that direction does not come 

 within the scope of this notice — are brought together in his 

 volume entitled Sovie Account of the Fauna and Flora of Sinai, 

 Petra, and Wddy 'Arabah, published by the Exploration Com- 

 mittee in 1891. The specimens collected both on the Polar and 

 Palestine expeditions are in the National Herbarium and at Kew. 

 Hart became a Fellow of the Linnean Society in 1887, but his 

 name does not appear in recent lists. 



For an account of Hart's striking personality and various in- 

 terests, and a general estimate of his work, reference must be 

 made to the biography by his intimate friend and companion on 

 many expeditions at home and abroad, Mr. E. M. Barrington, 

 published, with an excellent portrait, in the Irish Naturalist for 

 December, 1908. This contains a bibliography completing that 

 published in Irish Topographical Botany, p. cxxii.
