Hi,
I recived a plant orther 3 month ago. in the box, they was that plant I never ask for (great a bonus!). That plant came under the name of mini java fern. I never seen something call like that before and I find nothing on internet.

does anyone have an idea of what it can be?

Can it be narrow leaf java fern Microsorum pteropus ''Narrow''?

Regards.

Vladimir.

Yeah it can be beacause leafs are the exact same shape but after 3 month, the leafs have not grow more than 5 cm long. my other narrow grow faster than this.
