districts in Scotland. He forms a landmark between the 
time of Hooker and Greville and the present, and advanced 
our knowledge of Hepatice greatly. His British Hepatice, 
so far as completed, was published in 1874-76. He dis- 
covered Hremonotus myriocarpus during one of his visits, 
and also added Harpalejeunea ovata to the Scottish flora, 
probably also Gymnomitrium crenulatum and Marsupella 
Boeckit. 
Wititiam NIcHoL (1836-59). A few of Dr Nichol’s 
specimens appear to be incorporated in the Greville Her- 
barium, but otherwise no trace of them has been found. 
He was an acute botanist and may have been the first who 
found some of our species. 
JOHN SADLER (1837-82) added Riccia bifurca ? 
GEORGE Epwarp Hunt (1841 ?-73) discovered Mar- 
supella sphacelata on the Cairngorms, and probably also 
added Gymnomitriwm alpinum to our flora. 
JOHN WHITEHEAD (1833-96) was the discoverer of Mar- 
supella nevicensis. 
JOHN Sim (1829-1901) collected in the north-east counties 
and in Shetland. He added Gymnomitriwm adustum, 
Marsupella sparsifolia, Lophozia longidens, Cephalozia 
leucantha, Prionolobus Massalongi, Lepidozia trichoclados, 
and Frullania fragilifolia. 
ALEXANDER M‘KINLEY appears to have added Nardia 
minor and Plagiochila punctata. 
JOHN STIRLING STIRLING (d. 1900) investigated the flora 
of Stirlingshire with Mr R. Kidston. He appears to have 
done most of the part which related to Hepatice. 
Rey. JOHN FERGUSSON (1836-1907) collected in various 
parts of the Highlands. His additions to our flora are 
Fossombronia Wondraczekii, Marsupella ustulata, Hap- 
lozia atrovirens, Jamesoniella autumnalis, Harpanthus 
Flotowianus, Cephalozia pleniceps, and Scapania rosacea. 
CHARLES Scorr (1864-1907) collected in several parts of 
the south of Scotland and in Argyllshire. He added Mar- 
supella Pearsoni to our flora. 
For most of the dates of the above deceased botanists I 
am indebted to the indispensable Biographical Index of 
British and Irish Botanists, by Britten and Boulger.
