Gymno identification.

Post by ElieEstephane »

This is what i always thought was a G. Baldianum but comparing to another G. Baldianum i can see some differences. The color is lighter and the shape is taller rather than globular. The flower buds are red rather than green. Could it be just a hybrid?

It's not always an easy task to pinpoint the exact species of Gymnos but it could well be one of the varieties of G. anisitsii. It could also be G. baldianum. I have sown it 2 years ago and I now have ~20 2-year old plants and they all look quite different from each other.

Thanks for your reply! The one i thought was G. Baldianum flowered today and it's a white flower which is weird.

White flowers could be G. anisitsii, the one with red buds probably is baldianum.

There is also G. baldianum var. albiflorum --> see last Cactus explorer, p. 47.

Flower colour can vary in many species. The problem can be historically the plant collectors in the past did not collect a representative sample of the population and then nurserymen bred from only the most attractive forms. Therefore we get a standard, but possibly untypical clone in cultivation, which may not match the variation of subsequent re-collections in modern times.

If you read Graham Charles Gymnocalycium book you can see illustration of flower colour variation in quite a few species, also what was the same species being separated into other species or varieties on flower colour alone because in the past the describer did not know population variation..
