Cattleya schroederae is a species from Colombia, which is also the motherland of Cattleya trianae. Both species are very similar. Cattleya schroederae and Cattleya trianae var. concolor flowers are two of a kind and could easily be taken one for another if it were not for the very distinctive fragrance of the first.
As far as I know, very few varieties of C. schroederae are known, among them the alba and the albescens. The albescens flower bellow looks like white, but it is actually of a very pale pink, very difficult to capture in photos.
This variety venosa, in which the lip shows few veins in purple, is not commonly seen.
And here the most strange in my collection. Strange, but beautiful in its own way This is a petaloid flower (not peloric!), it has no sepals, which are transformed in petals. The dorsal sepal imitates the regular side petals, and the ventral sepals are interesting: their inner halves together imitate the lip and their external halves imitate the normal petals above.
