ybrid Dendrobiums now play a very important part in the embellishment 
of our Orchid collections, and are likely to do so in an increased degree 
in the near future; their beauty and floriferousness, and the ease with 
which they can be grown, all tending to make them very popular. The subject 
of the present plate appeared as long ago as 1874, and although not the first 
raised, it was the first to be described and figured. D. X Dominianum, which 
preceded it, was not described until 1878, though it had been in cultivation for 
some years previous. 
Dendrobium X Aimsworthi was raised by M* MircHe tt, in the collection of 
D* AinswortH, of Broughton, near Manchester, between D. aurewm and D. nobile, 
the former having since been stated to be the seed parent, though this point was 
not recorded in the original description. The seed was sown in March 1867, on 
a block of wood, and in February 1874 the first flowers expanded. On the 18 th. of 
that month it was exhibited before the Royal Horticultural Society, when it was 
deservedly awarded a First-class Certificate. Its appearance at that time may be 
seen from a figure in the Gardeners’ Chronicle (1874, pt. I, p. 443, fig. 94) which 
was prepared from a photograph, and M* T. Moore in describing it remarked, 
“ it is in truth a very distinct novelty, and will make a very attractive plant. ” 
In habit it closely resembles D. mobile, while the shape of the flowers is 
rather nearer to D. aureum; their colour is white, with a large feathered blotch of 
rich amaranth or claret-purple on the disc. 
The variety voseum, which is said to have appeared in the same batch of 
seedlings as the original form, has the sepals and petals tinted with light rose, 
and the white of the lip replaced by bright rose. A plant which was exhibited by
