Okay, that's good to know. It said you hadn't been on in months, since you added me originally, so I thought you must have blocked or deleted me.
This one is pretty useless. Flowering plants come in two main types, monocots and dicots. The leaves of monocots generally have parallel veins, and they usually have petals in multiples of 3. But dicots' leaves have branching veins, and their petals usually come in multiples of 4 or 5. So you can predict things like, if you see a leaf of a flower with parallel veins, the flower will probably have petals in multiples of 3.
