It's from the type location, so it is indeed L. henrici - and yes, these are the plants I collected seeds from. That said, the pictures were taking in a shaded forest in pouring rain, so the petals may very well be more spreading in cultivation. Protologue below, note it clearly says "perianthium albidum [...] campanulatum".
I'm heading to Huidong next, I suspect whatever Chen Yi has introduced of "henrici" originated there, thus they would in fact be L. huidongense.
