Syngonium steyermarkii is one of the more attractive and interesting Syngoniums I have seen. A few years ago I had no idea it existed but a good friend of mine had one plant and had started propagating it. I was fortunate enough to get one of his plants and have been growing it for a few years. It seems to not be near as fast a grower as some of the other species but once it took off it started moving. The leaves can get over 1 foot long and are very pinnate when mature. It also tends to have a bit of a sheen to the surface of the leaf. It is a climber and should be given a totem or tree. I am not sure what the flower looks like or what a completely mature leaf may look like as the largest one I have seen were just over 1 foot. Still most people do not ID it as a Syngonium.
