What rank to assign to hybrid formulas

According to the data quality requirements, taxonRank is a required field. However, what taxonRank should be used for hybrid formulas?

Example, which ideally should be written as:

Chenopodium album L. x Chenopodium hircinum

Note that hybrid is not an accepted taxonRank

Markdown got messed up (anyone care to correct, I cannot edit), here is the link to the example: https://www.gbif.org/species/141266176/verbatim

Note that GBIF can recognize hybrid formulas in name type. It would be good to have guidance on how to populate taxonRank for those.

Due to excessive spam links we have had to introduce messing up markdown. It is a real shame. Sorry that it troubles actual users

Hi @peterdesmet
If its a hybrid between two species, I would suggest using "species" as rank, if its a hybrid between subspecies, use "subspecies" as rank etc.

When the rank differ between the two hybridizing taxa, I don´t know what makes most sense, and it seems that the backbone uses the lower rank in some cases and the higher in other:

Maybe @mdoering knows?

The backbone uses the rank given by the original sources.
But the code does specify what to do in such cases:

If the postulated or known parent taxa are at unequal ranks, the appropriate rank of the nothotaxon is the lowest of these ranks.

Thanks for the reply!
