Drosanthemum globosum origin

This species has become trendy as of late and I got curious about it, went down a bit of a rabbit hole, and came back without satisfying answers.

I can only find a single source that identifies its native range. It isn't exactly a scholarly source, but it does have pictures purported to be of the plant in habitat. I came across what looks like the most recent academic work on the drosanthemum genus, which includes a phylogeny constructed using DNA sequencing. D. globosum is conspicuously absent from it. I see a d. semiglobosum, but that appears to be a different plant.

I know this isn't a typical posts, but I figured if anywhere had expertise on the subject it'd be here. So is this plant actually a hybrid or mislabeled/misidentified by sellers? Are these academic phylogenies not always complete? Or is there something else I'm not accounting for?
