DO CYPRIPEDIUMS SPORT? 
At page 20 of our January issue we gave some particulars about Cypri- 
pedium x Dauthieri and its remarkable sports; among them the one 
known as C. x Dauthieri, The Albino, in the collection of R. H. Measures, 
Esq., The Woodlands, Streatham. Shortly afterwards Mr. Measures sent 
a flower, which was practically identical with that called C. x Dauthieri 
var. Poggio Gherardo—the flower a peculiar light green with a little bronzy 
suffusion on the petals. And now the same gentleman sends a very 
different flower from the same plant, and still further illustrates its 
sportive character. Mr. Measures writes:—‘ You will recollect my send- 
ing you a flower of Cypripedium xX Dauthieri, The Albino. Well, the 
growth which bore that flower was divided from the plant and grown on 
simply by itself, and it now has two other growths which have sprung from 
it, one bearing the flower now sent.”* This is the form, irregularly striped 
and splashed with purple on the dorsal sepal, petals, and lip, to which the 
name of Rossianum was given by Reichenbach. Even the staminode bears 
a few small streaks and splashes of purple. Thus it differs from the one in 
the collection of Mr. Ross in not being constant in its mode of flowering. 
It isa most remarkable phenomenon, and so far as known, unique in the 
genus. ‘The peculiarity may arise from a partial re-separation of the mixed 
blood of the parent species, coupled with a tendency to reversion to a more 
ancestral condition, for the group to which C. barbatum belongs is 
undoubtedly more highly specialised than that which contains C. villosum. 
This much may be said, though how far one would have to trace them back 
before reaching their common ancestor, and what it would be like, are 
matters of speculation. The element of uncertainty as to the behaviour of 
this plant lends it an additional interest, as cultivators may literally be said 
not to know where they are. 
SACCOLABIUM MOOREANUM VAR. CANDIDULUM. 
Saccolabium Mooreanum was introduced a short time ago by Messrs. 
F. Sander and Co., of St. Albans. It was reported from New Guinea, 
though now it is said to have come from Sumatra. It is characterised by 
its dense racemes of small rosy flowers, whose segments are tipped with 
green. It has been distributed into several collections. It is interesting 
to note that a white variety has now appeared among importations of the 
same firm. It is simply an albino of the species, the rose colour being 
replaced by white, as it agrees with the typical form in every other respect. 
It is probably rare.
