know his individual fungus cultures as well as he did his favourite Orchids.” 
One of his most remarkable successes was the development of the albino 
race of Odontoglossums from O. crispum xanthotes crossed with other 
albinos. These have been a constant feature of the fine groups exhibited 
during recent years, and a number of details have been given (O.R,,. 
XXiv. pp. 164-167). It is a triumph of hybridisation, representing years of 
perseverance and experiment, with which Mr. Charlesworth’s name will 
ever be associated. 
Oflate years Mr. Charlesworth has paid a good deal of attention to 
intercrossing Odontoglossum and Miltonia, with a view to developing a 
race of hybrids with the character of the former but adapted for growing in 
a warmer temperature, for the American climate is as a rule too hot for 
Odontoglossums. At the last Chelsea show he exhibited four brilliant. 
Odontonias, one of which gained a First-class Certificate, and another a.

before his death the brilliant Vuylstekeara Brewii, in which the three 
genera, Cochlioda, Miltonia and Odontoglossum are combined, received an: 
Award of Merit (see p. 150). 
To enumerate a tithe ofthe interesting and brilliant hybrids raised by Mr.- 
Charlesworth would take a great amount of space, but in addition to a 
few mentioned above we may recall the brilliant Odontioda Charlesworthii, 
Miltonia Charlesworthii, Eulophiella Rolfei, and Charlesworthiara Alpha, 
the latter including the three genera Cochlioda, Miltonia and Oncidium, and 
the first member of an artificial genus dedicated to Mr. Charlesworth to 
which all subsequent combinations between the three genera will be referred 
In the popular Cattleya group his achievements have been remarkable, for 
he was ever out for improvement, and any good hybrid at once became a 
subject for further experiment. One ideal was a good yellow Cattleya, 
and no opportunity was lost of making across that promised the desired. 
result. Improvements in shape and colour were ever in view, and the large 
number cf certificated hybrids are a tribute to the good judgment and 
perseverance of their raiser. 
Mr. Charlesworth has been a member of the R.H.S. Orchid Committee: 
ever since the beginning of 1902, when he was elected for the first time. 
He was also for many years a member of the Manchester Orchid Society 
and a donor of valuable prizes, and he presented a {100 cup for the best.

Exhibition held in London in 1912. 
We shall never forget the many delightful hours spent in Mr. Charles- 
worth’s company, and his enthusiasm over the investigation of the different 
stages of the life history of his pets, for he was much more than a mere raiser, 
and .had mastered many of the details of microscopical technique. One
