Hi Beverly,
Although both are in the family Acanthaceae, they are different species and are even in different genera.
Justicia brandegeeana 'Yellow Queen' flower spikes are pendulous and have light yellowish-green bracts, like this:
The leaves are also different and tend to be a bit smaller, lighter green and less glossy on the Justicia brandegeeana.
I've grown both and loved them both. My hummingbirds have used both of them as they do most Acanthaceae plants that I've tried. I really enjoy the Acanthaceae family of plants and always snatch up any new species/varieties I find to try.
