MESSRS. WILLIAM BULL & SONS’ ORCHID EXHIBITION. 
Last year, it will be remembered, Messrs. William Bull & Sons organised 
a Show of Orchids and other plants to celebrate the Jubilee of their estab- 
lishment, and this year another exhibition has been held, which opened on 
May 13th, and produced a fine display. There were many forms of the 
well-known popular species, with numerous hybrids, particularly of 
Odontoglossum, with which the firm have been very successful. We were 
‘much struck with a batch of seedlings of O. crispum, obtained by crossing 
the blotched varieties Alpha and Franz Masereel, and showing a remarkable 
range of variation. Some were handsomely blotched, in others the colour 
covered the greater part of the segments except at the apex and margin, 
while others were ordinary white forms, one, however, having a large lip 
very heavily blotched with red-purple, and only an occasional spot on the 
other segments. We may be able to say something about some of these 
later. There were also four striking forms derived from the varieties General 
Roberts and Black Prince, varying much in shape and detail, but the 
blotches had retained the remarkable blackish purple colouring of the latter, 
while the lip showed unmistakably the influence of O. Hunnewellianum, 
which is clearly involved in the ancestry. Many other species and hybrids 
were also well represented, with numerous plants of Leliocattleya Baden- 
Powell, of which a large batch has been raised, some of the buff-coloured 
hybrids, among which a batch from C. Schroederz and L.-c. warnhamense 
showed a remarkable range of variation, forms of Cattleya Mossiz, Mendelii 
and Schroedere, and other well-known plants of the season, interspersed 
with suitable foliage plants and making a very effective display. 
Passing into the houses behind we were able to see the earlier stages of 
the work, from the tiniest seedlings upwards, house after house being filled 
with plants in all stages. Various Odontoglossums were in bloom, 
including hybrids of O. Edwardii, interesting batches from O. Pescatorei 
and luteopurpureum, QO. armainvillierense and spectabile, O. crispum and 
armainvillierc nse, and forms of O. Fascinator, with some good Odontioda 
chelseiensis, Vuylstekez and Diana, but want of space prevents us going 
into further details. 
The work of hybridising is being carried on with energy by Mr. Lakin, 
and many promising crosses were pointed out. Incidentally it may be 
remarked that some trouble has been experienced with the well-known fly 
that lays its eggs in the compost, and is so destructive to young seedlings, 
but it is found that it can be kept in check, by occasional fumigating.
