Through my job I have become familiar with the designation of 'grex' in Orchid names. However, we cannot enter these into the database.
How do you think we should enter:
Vanda Maria Bos 'Tropical Splendor' ?
Vanda is the genus, Maria Bos is the grex and 'Tropical Splendor' is the cultivar.

And here is the picture.....

Should it just be entered as Vanda 'Tropical Splendor' ?

Hetty, I don't know orchids but proper use of grex in orchid names are talked about briefly here.

"...In some plant groups, notably within orchids, where complex hybrid parentages are carefully recorded, the group system is further refined. Each hybrid is given a grex name (Latin for flock) which covers all offspring from that particular cross, however different they may be from one another. Individual cultivars may then be named and propagated by division or micropropagation. Although a grex is similar to a botanical hybrid in principal, backcrossing a member of a grex with one of its parents results in a new grex, with a new name, whereas backcrossing a hybrid makes no difference to the hybrid name. In constrast to groups, with grex names no brackets are used and grex is abbreviated to g. - for example, Pleione Shantung g. is a popular grex of hardy ground-living orchids while P. Shantung g. ‘Muriel Harberd’ is a particularly good cultivar, selected from the grex. ..."

Elsewhere on the RHS site they indicate grex is abbreviated gx.

Yes, I am aware of this, but my question was more about how (or whether) to enter the grex names in the database.

I think most likely what we should do is create a grex field, but should it be added across the board for all plants? No, it belongs only to orchids. But how do we set a grex field for just orchids?

Is there a complete list of all genera in orchids? If so, I can setup a databox area for orchids, similar to how we do with other plant types. Then we can put the grex field into that area.

If not, then we can just add "Grex name" under "Miscellaneous", I suppose.
