hybrids? Pitcairnia angustifolia x Pitcairnia bifrons?

Kawata. Zannanna djab, mawon, gran bwa.
Lesser Antillean endemic.
Quite common terrestrial herb of elfin shrublands.
St. Kitts, Guadeloupe, Martinique, St. Lucia.

May be hybrids between P. bifrons and P. angustifolia.
Another explanation is that P. bifrons and P. angustifolia and the intermediate forms are a single variable taxon, P. angustifolia.
DNA analysis would be very interesting!
