Ho hum, Kleinia petraea on Discover Life shows a different plant. Something odd is going on with these two!

The description on jstor seems to fit the plant here ..

I've searched high and low and I cannot find two different plants other than the one on Discover Life, would they get it wrong? The source of the plants says "Botany Greenhouses"
