HE question of the production of albinos from coloured parents (see p. 
259) has taken an interesting form. At the R.H.S. meeting held on 
November 7th forms of Cattleya Pretoria and C. Pretoria alba, the former 
with purple, the latter with white sepals and petals, were exhibited from 
the collection of R. G. Thwaites, Esq., and Mr. Thwaites informs us that 
both were derived from the purple C. Peetersii crossed with C. Dowiana 
aurea, and that he has other whites from the same cross. Messrs. Sander 
& Sons also exhibited Cattleya Maggie-Raphael var. albo-rubens, with 
white sepals and petals and a coloured lip, and they inform us that it 
flowered out of a batch of coloured seedlings from dark parents. These are 
fairly parallel cases to that of C. Corona alba, for both parents of the latter 
were half derived from C. Dowiana aurea. And the curious tendency of 
the latter of reverting to white when crossed with purple is also illustrated 
by examples of C. Prince-John that have appeared. 
And there are cases where C. Dowiana aurea is not involved, for we may 
recall the beautiful Lzliocattleya Fascinator-Mossiz var. Moonlight, which 
flowered in a batch of coloured seedlings with Messrs. Charlesworth, and 
received an Award of Merit from the R.H.S. at the Holland House Show 
were Lc. Fascinator X C. Mossiz Reineckeana, and 
in 1915. The parents 
e sepals 
the seedlings also included coloured varieties and forms with whit 
and petals and a coloured lip. 
An interesting case of the production of a white where one parent only 
was coloured was exhibited at the last R.H.S. meeting by Messrs. Charles- 
Thompsonii, derived from Brassocattleya 
worth, namely, Brassocatlelia 
It is the first seedling to bloom, 
Veitchii crossed with C. Gaskelliana alba. 
and is pure white with the usual yellow disc to the lip. 
arents, Messrs. Charlesworth inform us 
As for reversion from white p 
x Mossiz 
that in a batch of C. Suzanne Hye de Crom (Gaskelliana 
Wageneri) they obtained both pure white and pale mauve-coloured forms.
