I know Amydrium zipp to have long, slender leaves, and was very surprised to receive a plant from Tropiflora that had fat / wide / broad leaves. The stem is clearly from older growth, but the leaves are so different.
Any insights? Two forms? Something else?
Included is a picture of the plant from Tropiflora. (Now that I recall, maybe 5 or 6 years ago, I had bought one from Tropiflora, which had the usual skinny leaves.)
