The word rachis comes to us from the Greek word for backbone.
But, plants don’t have backbones!
That’s true. But they often have a main axis or shaft, similar to those seen in feathers. In fact, the shaft of a feather is also called its rachis [ray-KIS].
Botanically, the rachis can be the central stem seen in ferns, in compound leaves, or in the portion of an inflorescence found above the peduncle. Rachis is a type of stipe. Stipes are stalks that support other structures.
Now, when someone mentions a rachis or a stipe, you will know what they are talking about!
