I got this plant in a trade today, but the person I got it from doesn't know what it is. I'm tempted to say vulgaris, because it looks like what I have grown before as vulgaris. Also, does anyone know whether Meadowview's vulgaris is really vulgaris, or is it macrorhiza? The picture they have of vulgaris looks more like this plant than the plant they have as vulgaris, so I thought that it was really macrorhiza.
This is what Meadowview lists as vulgaris:
The bristles are much thicker on the second plant, and they are more brittle. On "vulgaris", they seem more like hair. Also, the person I got it from said he got it in a fish shop, so I thought of foliosa, since I've heard that it is the most common Utricularia in fish shops.
Can anyone clear this up?
