home fortheremainder of his life. The previous summer holiday was 
passed in the extreme north of Scotland, during which he gathered 
his first new hawkweed, afterwards named by him H. orcadense. 
From the ein ag his first settling in Derbyshire the flora of 
we county beca matter of interest. The country was ex- 
ored in ifforent directions and critical or doubtful plants were 
eratin into the garden to be watched. e companionship of 
the Rev. W. H. rahi Ss was caging and much enjoyed. All this 
about 1893, the compilation of the Flora of Derbyshire. For this 
purpose some of his summer holidays and occasional short visits 
were made to all parts of the county, his wife accompanying him 
at all such times. The experiment was made of dividing the 
unty, no river-basins but by geological Anon e s; and the 
book, published in 1903, is a witness to the unwearied diligence 
and critical ability, both in field-work and in asenitiie research, 
with which he accomplished his task. Finding the mosses had

_ in none, he studied both these classes of plants, to good purpose 
as the records show. The Rubi were attacked in the first place 
with another object in view, viz. the Set of British Rubi, which 
he joined with three others in issuing, and to which he contributed 
his fair share, adding one new species, R. dwrescens, to the British 
list. The Set of British Willows and the Set of British Hieracia, 
both of which he shared in © atari 3 with his brother, followed 
in quick succession; the preparation for these had been going on 
for years, the garden at Shirley being used for growing and ob- 
serving scores, or even hundreds, of the hybrids of one genus and 
the critical forms of the other, while experiments were made in 
hybridization of Salices, and in the constancy of various Hzeracia 
species by raising crops of ings. 
The gathering of material for the later fascicles of the last- 
named Set led him to search the Yorkshire dales, the Lake Dis- 
trict, and some of the Welsh “ for os wkweeds, in company 
with the Rev. A. Ley; and these excursions revealed the oenere 
tent to call H. murorum L. His last work of importance was to 
publish an Account of the British Hieracia, in which, after much 
res of poner igocene Sa treatises on the genus and Scandinavian 
uch correspondence with Aman. H. Dahlstedt, he 
benefit of many fellow-botanists, who have found that he would 
spare no trouble to let them share his knowledge in this perplex- 
ing genus. The Hieracium list in the new edition of the London 
Catalogue is from his pen; and it is no secret that he had 
to continue, and was looking forward to carrying ak Mr. F. J. 
Hanbury’s long-mnterenpeet Monograph.
