Intergeneric relationships in the Gorteria clade of Arctotideae-Gorteriinae (Asteraceae), with description of a new genus, Roessleria: https://www.sciencedirect.com/science/article/pii/S0254629918307737

The corresponding taxonomic changes are all accepted by POWO.

Before any changes are made, I would like to briefly consult whether there are any good reasons for not making these changes. Otherwise, I would like to revise this group on iNaturalist.

fine by me

Still outstanding are:

Gorteria angustifolia (=Hirpicium angustifolium 2)
Gorteria antunesii (= Hirpicium antunesii 1)
Gorteria beguinotii (= Hirpicium beguinotii [not on iNat])
Gorteria gracilis (=Hirpicium gracile 3)

Berkheyopsis echinus (=Hirpicium echinus 23)

Roessleria armerioides subsp. armerioides (=Hirpicium armerioides Mountain Gerbera 69)

- subsp. rudatisii
Roessleria bechuanensis (= Hirpicium bechuanense 55)
Roessleria gazanioides (= Hirpicium gazanioides 50)
Roessleria gorterioides subsp gorterioides (= Hirpicium gorterioides 17)
subsp. aizoides
subsp. schinzii
Roessleria linearifolia (= Hirpicium linearifolium 2)

For some reason these have not been accepted in BODATSA.
All these names are still currently accepted. (which is really odd for a SAJB article).

Let me ask ...

Posted by tonyrebelo 5 months ago

Ok, please let me know.

Xmas recess - no response yet. Sorry.
Office only reopens 15 Jan, so I I dont expect a reply before then.

@tonyrebelo I don't want to be annoying, but what is the current status on this? Did you get an answer from them?

Posted by kai_schablewski 3 months ago

OK: the South African ones are on BODATSA, go for it.
For some reason the Namibian ones are not included - will need to check, but process the lot.

I have now moved the remaining species and finally synonymized the genus Hirpicium with Gorteria.

This flag can be closed.

But might some of Hirpicium observations not be Berkheyopsis and Roessleria, rather than all being Gorteria?

Posted by tonyrebelo 3 months ago

Of course. You can find all these species with the old Hirpicium names.

The type species of Hirpicium belongs to Gorteria so the genus is specifically a synonym of Gorteria. It is not automatically also a synonym of the genera that have been excluded from Hirpicium.

see: https://www.inaturalist.org/taxon_changes/139735

This might be something that should be discussed in the iNaturalist forum, because this actually affects the whole approach to synonyms on iNaturalist.

Until now I had never given much thought to how other iNatters handle this.

I would have created a 3-way swap: Hirpicium to Gorteria & Berkheyopsis & Roessleria
and the SWAP would automatically have kicked any generic ID of Hipricium to Subtribe Gorteriinae - which is the ideal desired effect assuming we dont know more, and there is geographical overlap, preventing separation by atlasses.

(if I was a purist, I would then have deleted the synonyms from Berkheyopsis & Roessleria).

While taxonomically Hirpicium is a strictly synonym of Gorteria, in effect Hirpicium has been split, and so is a "synonym" of Gorteria & Berkheyopsis & Roessleria.
(the fact that it was a mistake and should never have been used except as Gorteria, is purely taxonomical: in reality it existed and was used for all three genera, and anyone trawling the older literature will need to know this).

Taxonomy is one thing.
The problem on iNaturalist is that people made IDs to generic level of Hirpicium, that could have been any one of these three genera, not just the strict Gorteria. These are now all under Gorteria, which - for example in Botswana, is now 32 instances of Roessleria sp which are now incorrectly swapped to Gorteria instead.
