Well, I hate to be the bearer of bad news, but you have just accidentally landed in one of the biggest iNat forum controversies.
The problem is that the taxonomy used on iNat has split dandelions into hundreds of micro-species, so Taraxacum officinale and Taraxacum erythrospermum are in fact not the only dandelions found in Maryland.
