Stop reading horticultural dictionaries as if they were valid references.
They are full of errors.

Heliconia aurantiaca Ghiesbreght is obviously in the genus Heliconia.
However, the correct name for the species is Heliconia psittacorum L.f. The
color of the bracts varies from yellow to orange to red.

Strelitzia is a strictly Old World genus.

According to the ICBN, you cannot reject a species epithet just because it
is inapproprate or you don't like it.

You lucked out this time because the species has an earlier valid name.

Do a google image search to find pictures.

This picture looks very much like that in the American Hort. Soc.
Encyclopedia of Garden Plants which is listed as Heliconia aurantiaca
from Central America. Sorry I can't do a scan of it. 'Auriantiaca' means
yellow or golden, so it would fit with the common name on the picture
you saw.

I'd translate 'auriantiaca' as orange; yellow/gold would be 'flava',
'lutea' or 'aurea'.
