The history of Dendrobium Wardianum, one of the most beautiful and popular species of this remarkable 
genus, has already been traced in the fifth volume of the Lindenia (t. 225). 
his rich species has been introduced in quantity for many years, in 
order to supply the wants of amateurs and those who cultivate it 
on a large scale for cut flowers. It is interesting to note that hitherto 
it has shown very few variations. Some forms are a little larger or smaller 
than the type, or a little darker or lighter in colour, though with regard to 
colour the differences observed have been very slight. The only very distinct 
variety known was described by ReicHensacn, in 1876, under the name of 
D. Wardianum candidulum. Its peculiarity consists in its having the sepals and 
petals entirely white, and the two purple-brown spots at the base of the lip 
much smaller than in the type. 
The variety Lindeniae, which we figure in the annexed plate, is still more 
distinct and remarkable, because it is a true albinos of the species. It has flowers 
entirely white except that the orange-yellow blotch on the disc remains, as in the 
case of albinos of Cattleya Trianae, C. Eldorado, C. labiata, and others. 
We may also announce that shortly after the appearence of this superb 
variety, a Belgian amateur, M. Mapoux, exhibited another very interesting one, 
which fairly completes the series. This form, which was exhibited at a meeting 
of the OrcHIpEENNE, has the sepals and petals white, and the two spots at 
the base of the lip of a very curious pale colour. 
The variety Lindeniae made its appearence at the meeting of the ORCHIDEENNE 
in February 11th. 1894, when it was unanimously awarded a First-class Diploma 
of Honour. It has large and well developed flowers, and will not fail to be 
highly appreciated, as are all white varieties of typically coloured species. 
It is dedicated to Madame LINDEN. ont
