OK, I'll bite!
I removed the common name Hard Grass from Desmazeria rigida -- easy fix.
The iNat taxonomic framework (Plants of the World Online or POWO) currently accepts Catapodium rigidum, with Desmazeria rigida as a synonym. Any objection if I update the iNat taxonomy to reflect this, and sink Desmazeria rigida under Catapodium rigidum?
Sclerochloa rigida has a different basionym according to International Plant Names Index (IPNI). I think you meant Scleropoa rigida, which POWO and iNat also show as a synonym of Catapodium rigidum.
Sclerochloa dura currently has the correct common name of hardgrass.
Sclerochloa rigida does not seem to be accounted for anywhere in iNaturalist or in POWO. But Sclerochloa rigida var. majus is considered a synonym of Catapodium rigidum var. majus in POWO. @sedgequeen Does this seem right to you? Should we add POWO's accepted infraspecific taxa for Catapodium rigidum: subsp. hemipoa, var. majus, and subsp. rigidum?
Desmazeria rigida and Catapodium rigidum are clearly the same thing and Catapodium has priority over Desmazeria.
Now the issue has ben fixed.
There are many Sclerochloa rigida binomials:

At least the last one is synonym of Catapodium rigidum, while the first three reported in IPNI seem to have a different type so one should take a look at the protolog/illustration/type in order to ascertain what they really are.
Also Scleropoa rigida si synonym of Catapodium rigidum:
http://ww2.bgbm.org/EuroPlusMed/PTaxonDetail.asp?NameCache=Scleropoa%20rigida&PTRefFk=7100000
subsp. hemipoa and subsp. rigidum are two accepted subspecies and var. majus is accepted as well.
Yes, I'm sorry about writing Sclerochloa when I meant Scleropoa.
Thank you for fixing this.
@blue_celery Yes, it looks like we are seeing the same things. Thank you for the taxon swap (https://www.inaturalist.org/taxon_changes/56110).
I went ahead and added the three infraspecific taxa (and their synonyms) from POWO, and added the Taxonomic Framework Relationships for each one.
Anything else we are missing? Can we resolve this flag?
for me it is solved

"Regarding observation https://www.inaturalist.org/observations/22867765#activity_comment_2792331
I’ve been down this rabbit hole before! There’s been a serious confusion of scientific names and even species concepts for a couple small weedy grasses. I think Flora Europea has them confused.
Fern-grass = Catapodium rigidum = Desmazeria rigida = Sclerochloa rigida. (W3Tropicos & USDA Plants) This observatoin is Desmazeria rigida, and it’s Catapodlium rigidum. So far so good. They should have the same common name, but in iNaturalist one is Fern-grass and one is Hardgrass.
Hard Grass = Sclerochloa dura. (W3Tropicos & USDA Plants) iNaturalist uses Hard Grass (or Hardgrass) as the common name for Sclerochloa dura.
iNaturalist needs to fix this!
