HI .. I ve been trying to id these plants but unfortunately my field guide to costa rica´s plants is quite limited... maybe you will be able to help me... They where all collected around Colorado, in San Jose province. the first one is simple leaf with mayor veins palmate, secondary veins ladder like, pointed tip. Color, greenish-white... The second one is a fern, blunt point, lobed leaflets down near the rachis, dark green colored. The third one has rounded leafs and it grows in groups, dark green colored. I hope these images wwork better for the id.. thanks toni and eileen!
Try here to learn how to post photos to the forum. If you have any questions about posting them, please ask because there is no way we can help ID your plants without them.
Hope you find an ID soon for your plants. It might be a good idea if you could post photographs of any others you want named a little bigger though as it's easier for us to help identify them for you.
