202 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
Pyrus intermedia^ Ehrh., synonymous with P. scandica, Aschers., 
has a var. scandica (Fries) from Denbigh, Brecon (but not the Isle of 
Arran), var. Mougeoti (Soy.-Will.) from Monmouth and Hereford, 
and as var. c. the P. minhna, A. Ley. The name P. pin 7 iatifida^ 
Ehrh., is retained (as it is said not to be synonymous with the 
P. hybrida, Moench.) for the Isle of Arran plant, which probably 
is of hybrid origin. It is the Sorbus arranensis, Hedl. 
The book is an important addition to the British arboricultural 
literature. 
The year 1906 has been remarkable for the great losses 
Botanical Science has experienced in the deaths of so many of 
its devotees. The places occupied by Sir Mountstuart Grant 
Duff, C. Baron Clarke, William Mitten, Harry Marshall Ward and 
F. H. Arnold will be difficult or impossible to fill. 
Sir M. E. Grant Duff, G.C.S.I., born in 1829, died Jan. 12, 
had a most distinguished career. He was a warm-hearted friend, 
and a charming litterateur ; his ‘ Notes from a Diary ’ will give 
delight to many thousand readers, and his touching and graceful 
memoir of Lord de Tabley prefaced to the ‘ Flora of Cheshire,’ 
will make an abiding impression on the memory, and was 
a worthy tribute to a distinguished man. He loved to see our 
British plants in their place of growth, and did much to stimulate 
the love for them in the minds of his many young friends of both 
sexes. Even during his last illness he was able to write a letter 
expressing his joy at seeing Orchis simia. 
Charles Baron Clarke (see ‘ Journ. Bot.’ 1906, p. 370) was 
born at Andover in 1832, and died at Kew, Aug. 25th, 1906, and 
published a ‘List of Andover Plants’ when at Calcutta in 1866. 
He collected an immense amount of plants in India during his 
connection with the Educational Department (over 25,000 sheets), 
which he presented to Kew, but of his Botanical work in India 
and his publications there is no space here to consider. He was 
a most charming man, and it was a great delight to meet him at 
our mutual friend’s (Henry Willett) house at Brighton, and listen 
to the account of his exploration of the Indian flora. It appears 
to the writer that a really good botanist is one of the most interest- 
ing individuals ; unlike the devotees of some sciences, the effects
