have not only the shape of this parent, but very nearly the coulour also, and it 
is very interesting to observe the wide range variation, according as the charac- 
ters of one or the other parent predominates. The sepals and petals may be light 
yellow marbled with pale pink, and in some of these pale forms the yellow 
appears chiefly along the nerves, giving a reticulated appearance. Frequently the 
pink colour is deepest near the margins. 
The variety here represented has the sepals marbled with pink on a light 
ground, the petals being of a deeper shade, and the front lobe of the lip very 
richly couloured. It appeared with M. le baron F. pr RotuscuILp, chateau de 
Laversine, France, during August last. 
The occurrence of these different forms is very interesting, and seems 
to show that the two species cross very readily where they grow together on 
the western Cordillera. It is only here, where the areas of two parents overlap, 
that C. X Hardyana has been found, a fact which taken in conjunction with the 
combination of characters seen in C. X Hardyana, leaves no doubt of its origine 
and parentage. C. Dowiana grows in Costa Rica, and its variety aurea 600 miles 
further south near Frontino, on what is really a southern extension of the same 
mountain range. The other parent grows on all three Cordilleras, western, cen- 
tral, and eastern. The localities given are : Frontino on the western Cordillera; 
from Amalfi southwards to beyond Medellin on the central Cordillera; and from 
La Palma to beyond Flores on the eastern Cordillera. It is said to range from the 
seventh to the fifth parallel of north latitude, south of which it is replaced by 
C. Trianae.
