Because of my talk, Lisa Vinzant of Hawaii sent me a photo of her Neoregelia dungsiana obtained from mainland USA. This showed short stolons, wide numerous red-tipped leaves and does not seem to match Pereira's description. I would suggest that this is the same as that offered by Birdrock Tropicals and thus is being grown in the USA under this name.
I would have expected a plant similar in shape to what we grow in Australia as Bennett 81549 BUT with stolons like N. sapiatibensis or N. hoehneana. The only other discrepancies that I could find between Bennett 81549 and N. dungsiana are :
Scape 3cm long not 5cm
Sepal joined 1mm not 5mm
Petal 2.5cm long not 3cm
Flower scented
It would appear that Bennett 81549 is closer to N. dungsiana than the plant being offered in the USA.
Eventually we may be able to acquire a true Neoregelia dungsiana to show you but in the meantime, WATCH THIS SPACE"
