| If you look closely at the leaves of an oncidium alliance plant you will see a thin line at the top of the bulb where the leaf starts to grow. This is the point where the plant can disconnect the leaf from the bulb. It comes off as a clean cut.
These plants discard so many leaves they have evolved an easy method to trim themselves. The leaf becomes totally brown and falls off. The bulb continues to look the same an acts as a food and water reservoir for the plant.
