    pics are kind of dark - so a bit hard to see. it's some kind of aroid. most probably a philodendron. could also be an anthurium or a monstera, though. maybe a strelitza?

    has it ever flowered? if so, what did the flower look like? color, shape, etc.

    steve or beth or someone will be along with better info/help than i can give :)

    I'll try to get lighter ones.

    So far it hasn't flowered and I don't think it's going to. It might though.

    It's not a philodendron, anthurium, monstera, or a strelitza though. I looked up pictures of them and only the philodendron and the anthurium looked anywhere close to the plant I have.

    Someone said its fairly common, though they didn't elaborate.

    Certainly an aroid and I believe it is a Philodendron. I can see a sulcus (canal) in the petiole that supports the each leaf and other characteristics to the stem (main axis of the plant) that suggest it is likely a Philodendronn.

    You should know there are close to 1000 species of Philodendron so it would be highly unlikely for you to find photos of each species on the net.

    If possible, please take the photo with the light behind you instead of the plant. These photos will help to determine which species unless it is a hybrid:

    1) A photo of the top of a single leaf showing the petiole (leaf support).
    2) A photo of the underside of the leaf again showing the attachment of the petiole.
    3) A photo of the stem which is the "stalk" at the center of the plant. Make this as close as possible so I can see the roots.
    4) If there is a new leaf forming on the plant please photograph that portion as well. There should be a cataphyll which looks like a sheath surrounding the new leaf. If this is colored or unusual in any way that is very important to determine the species.
    5) If you have ever seen this plant produce an inflorescence (what most people call a "flower") a description or photo would be great.
    If you can take a macro shot of the top of the petiole that would be really helpful. Sometimes the petioles are sulcate and possess a number of tiny grooves running down the length. If you can't get a photo please take a magnifying glass and look closely inside that groove. Tell us what you see if anything. Again, the petiole is the stalk that supports the leaf.

    This may be a hybrid and if so the best we can do is tell you the possible parentage.

    I blew up one of your photos by 300% and can almost guarantee I know the parent species which is a Philodendron from Central America but I would really like to see more photos before making a commitment.

    The plant is fairly common in collections and is often used as one parent of many hybrid variations. Joclyn you asked for one of these last year and I never got you a specimen! Remind me again when we come up with the ID.

    The color of those cataphylls as well as the color of the petioles is very important. Tell us all the colors you see which may be variable throughout the plant. I also need to be able to see the main veins in the leaf so photos of the top and bottom of the leaf are important.

    Chances are you'll find it on this page: http://www.exoticrainforest.com/Grow or Growing Philodendrons.html

    Just click any photo to find the name.

    Still can't tell a great deal from the photos but it strongly appears to be Philodendron erubescens or a hybrid with that species as one of the parents.

    Check the photos on my page and see what you think.

    http://www.exoticrainforest.com/Philodendron erubescens pc.html

    Please remember, Philodendron species are highly variable and slight differences in the appearance of a plant do not indicate a different species. Slight differences (sometimes big differences) in the shape of the leaf, the color of the leaf, the petiole, the stem or other plant parts do not play a role in identifying a species. Aroid leaves also go through morphogenesis as they grow and change exactly in the same way a baby changes into a youngster, a preteen, a teen, a young adult, an oder adult and an elderly person. Those natural changes are known as ontogeny and all aroids do the same thing.

    The two characteristics that can clearly determine the species are the shape of the cataphyll and the sexual structure of the inflorescence. I don't believe you've seen an inflorescence and I can't clearly see a cataphyll in your photos. The cataphyll is the "sheath" that surrounds a newly emerging leaf blade.

    There is an article on my website about natural variation.

    I think you might be right.

    I also think there's at least one cataphyll on my plant. I'll see if I can't get a photo of it.

    These are new cataphylls and haven't begun to reflex (turn back wards) but I would say this is Philodendron erubescens or a hybrid with the species as a parent. If you turn on your flash and not put the plant with the window behind the plant your photo quality will improve. The window is creating a great deal of flare.
