| | Re: Rotala sp. Green Narrow??
I'm bringing this topic back to light. I believe there are definitely two types of Rotala sp. 'Green' in the hobby at the moment. The following pictures were taken from the same tank within minutes of each other at similar exposures. The alleged Rotala sp. 'Green Narrow' (obtained through Cavan from Aqua Forest) is planted on the left side of the tank and the 'normal' variety of Rotala sp. 'Green' (obtained long ago through a trade) is on the right side of the tank.
Here's a close-up of the two. Again, the Rotala sp. 'Green Narrow' is on the left. Notice how the leaves are slightly thinner and grow more upright.
Here's a full shot of the growth pattern of each plant. Notice how the Rotala on the left differs again, not only in appearance, but also in growth pattern. The Rotala sp. 'Green Narrow' has a more vertical growth pattern. Both stands of stems were trimmed at the same time in the same manner.
All this isn't to say that the two are necessarily different species. It's very likely that they are the same species from two different original collection locations. However, I do feel that the differences are great enough to warrant a distinction.
