Society. In 1880 his great monograph on the Genus Lilium 
appeared, a book which has long been out of print, but is still the 
recognised authority on the subject. From 1880 to 1906 he 
published 27 papers on the lepidoptera of many regions, and 
described numerous new species of his own finding. In 1888 
there appeared in the Transactions of the Entomological Society 
his “Lepidoptera of Sikkim,” a very valuable ‘record of the 
numerous species of that country. He was in Formosa in 1912, 
and succeeded in et home alive several — of the 
splendid Mikado Pheasa 
Elwes’ botanical aiicldsies in all the countries he visited 
‘were very numerous, and he introduced many species. None of 
these in recent years have aroused oreater interest than the 
two Southern beeches, Nothofagus obliqua and N. antarctica, 
which he introduced from Chile in 1902. Both had been pre- 
viously in cultivation but had disappeared from gardens almost 
entirely. The School of Forestry at Cambridge has greatly 
benefited by his munificence, and owes many of its finest timber 
“specimens to him. In 1900, with his friend, Prof. Augustine 
Henry, as collaborator, Elwes began the preliminary labours 
which resulted in the production of that monumental work, 
‘The Trees of Great Britain and Ireland. The first of the seven 
volumes appeared in 1906, and the last in 1913. Never before 
‘has a book on European trees been attempted on such a scale, 
and with so lavish an expenditure of money in its preparation. 
Indeed, it can only be compared with Sargent’s Sylva of North 
“America, that great fourteen-volume record of American arbores- 
cent species. Elwes especially undertook the task of visiting 
every place in this country where remarkable specimens exist, 
as well as every European collection of note. The number of 
trees described which Elwes himself had seen and measured is 
overwhelming evidence of the untiring zeal he devoted to this 
work, well-nigh impossible except to one in whom the boyish 
spirit of adventure survived. The fact that both he and Henry 
had seen almost every species in its native land gave great addi- 
tional value to their descriptions of the cultivated plants. Never 
was a great labour more fittingly divided, Elwes making incessant 
journeys to see and take particulars of specimens, and Henry, 
‘the exact botanist, writing the scientific descriptions. To the 
writer the ubiquitous character of their grip was vividly 
-brought home when in 1917, during war service in 
he had occasion to visit a little known sean in the Médoc. 
He saw there some remarkable Oaks, Pines, and other trees of 
the S8.E. United States, grown from seeds sent home by Michaux 
100 years ago. Though the existence of these trees was scarcely 
known in France, the proprietor stated that a few years previously 
two gentlemen had come from London to see them, a Monsieur 
Elwes and a Monsieur Henri! Some twelve years ago the writer 
paid a visit to Grasse, in the Riviera, on the business of a public 
‘company; Elwes ‘accompanied him solely to see two individual
