INTRODUCTION clxxxiil 



Ropliidosieylum tegeticula, Isoptenjgium acuminatum, Acrocladium trichodadinm, 

 and Hypnum devexum, are described in Joiirn. Bot. (1892) 97-9. Some 

 New Zealand Mosses and Htpaticae, in w hicli Hehnsia collina is first described, 

 in Journ. Bot. (1894) 78. In the Naturalist (1879 33 he describes 

 Bjyum origanum as a British plant. 



Mr. Boswell also compiled the London Ca'alogue of British 3Iosses for 

 the Botanical Locality Record Club, to which he acted as botanical 

 referee. He prepared the valuable list of Mosses of Oxfordshire and 

 Berkshire which appeared in my Oxfordshire Flora, and he kindly 

 allowed me to consult his note-book for the purpose of copying out 

 any notes it contained on the flora of Oxfordshire and Berkshire. 

 The destruction of so many of the wild portions of ground in our 

 neighbourhood was always a theme for him to discuss and deplore, 

 and he was wont to take a pessimistic view of the field- botany of the 

 future. By his death I lost a valued friend and kindly helper. 



Dr. F. Arnold Lees, the author of the excellent Flora of West IjEEs, F. A. 

 Yorkshire, &.C., and who was for some years editor of the Fteport of the 

 Botaniccd Record Club, resided for a short time about 1885 at Beading. 

 Whilst theie he gave a precise locality for Diplotaxis muralis i^ which 

 was included as an unlocalized plant in Mr. Flower's list and probably 

 not correctly named), and for some other plants about Reading. 



My Flora of Orfurdshire, published in 1886, contained notices of some 

 of the most interesting plants of Berkshire, especially those which 

 occur near the border-line of the two counties. Though Berkshire 

 had been explored at various times by a somewhat large number of 

 botanical observers, its tieasures were not exhausted, as will be seen 

 by the considerable additions made to its floia by my friends and 

 myself. My chief fellow-workers have been Mr. Boltox King, a valued 

 companion in many a pleasant ramble, whose keen eye left little 

 unnoticed, and who discovered Galium Bakeri and other forms not 

 before recorded, and who made a list of plants in the neighbour- 

 hood of Eton ; Mr. F. Tufnail, an active and valued coadjutor, 

 who was the first to record Lepidium heterophyllum, var. canescens, 

 and the more or less naturalized Eranthis {He'leboroides) hyemalis, An- 

 thoxanthum Pudii, Euphorbia Cyparissias, and Mercurialis annua ; the Rev. 

 Gr. F. DE Teissier, my Northamptonshiie helper, who had removed to 

 Berkshire, and who found Anemone rammcnlioides as a naturalized 

 plant there ; the Rev. F. W. BEKNExr, another valued friend and 

 companion in many a ramble, who discovered Galeopsis (versicolor) 

 speciosa near Wittenham. The Hon. J. L. Warren, afterwards Lord 

 de Tabley, gathered Stachys ambigua near Holmwood. My own dis- 

 coveries, published in the Flora of Oxfordshire, seme of which had been 

 already published in the pages of the Jcurnal of Botany and in the 

 Reports of the Botanical Record and Exchange Clubs, are as follow : — Papaver
