@Tapirlord, what do you need in order to determine whether this is Opuntia ficus-indica, O. stricta, or other Opuntia? I recorded nearby big plants Opuntia ficus-indica (Indian Fig, Spineless Cactus) in 2018 and @RWPurdie made a Herbarium collection a few months later, CANB909518.1. From her description of the drying process, I won't be collecting any specimens.
Mike. Re your question, in the Cacti & Succulents category, Crassula sieberiana has lots of sightings, fewer for the others. CarbonAI is not trained well enough for other species in category.
