David Orr. who died 1892, was an assistant to Dr. Moore in Glasnevin 

 Gardens. He collected and studied the mosses of Antrim. Dublin, and 

 Wicklow. Many specimens of his collecting are in the British Museum, the 

 Xational Museum, Dublin, and other herbaria. He was the author of a short 

 paper entitled "Some Mosses collected in Ireland." that appeared in the 

 " Journal of Botany," 1881, pp. 83, 84. Much doubt exists as to some of 

 Orr's discoveries, which prevents reliance being placed upon his work unless it 

 is corroborated by other botaui;>. ^ee under Ptilium crista-castrensis, 

 Neckera pennata, and Pterogonium ornithopodioides^] 



William McCalla 1 1814-1849), a native of Galway, who discovered Erica 

 Mackaii, and did good work as an algologist, was also a muscologist, there 

 being many specimens of Irish mosses of his collecting in the herbarium of 

 Trinity College, Dublin. 



Captain Frederick Wollaston Hutton, Deputy Quartermaster-G-eneral to the 

 Forces in Ireland, died in Xew Zealand (1905). Whilst resident in Dublin 

 he studied Irish mosses and collected in the four provinces. When he left the 

 army he emigrated and settled in Xew Zealand, where he became Professor of 

 Geolo?v, in which science he was a zealous worker. He discovered two mosses 

 new to Ireland, Aniblyxtcgium moUc and A. dUatatum. He formed a herbarium 

 of British and other European mosses in six volumes, which contain 1283 

 specimens, representing 637 species, illustrated by 977 coloured microscopic 

 drawings, beautifully and accurately done by his own hand. David Orr 

 contributed largely to this collection, which is now in the herbarium of the 

 present writer. 



The Rev. M. J. Berkeley, f.ls., in his " Handbook of British Mosses " 

 (1863 ), gives " Ireland " as the locality for 49 species.
