One of my favorite plant families is the "Prayer plants" from the botanical family Marantaceae. These include the genera Calathea, Ctenanthe, Stromanthe, and Maranta. I don't have a lot of plants from this family, but I added two new Calatheas recently through plant trades. I was able to share my Ctenanthes with two friends and they each shared a Calathea with me. Plant trading is so much fun because the only money spent or exchanged is to pay for shipping and you get "free" plants in the mail.
The leaves of Calathea concinna are marked much like those of Ctenanthe burle-marxii, but there are some distinct differences. Ctenanthe burle-marxii has rectangular leaves with a point at the end, while Calathea concinna has ovate leaves.
The foliage is of Calathea musaica is unlike any of my other Calatheas. In fact, it is unlike any other Calathea in existence - quite unique!
