The axis of a flowering branch or the cenral stalk of a compound leaf..
The midrib of a compound leaf The rachis is an extension of the actual leafstalk.
a midrib of the lamina, or of a primary, secondary, tertiary etc. pinna. When unqualified, refers to the midrib of the frond, i.e. the main axis above the lowermost primary pinna. Also spelled rhachis. pl. rachises.
axis bearing flowers or leaflets; i.e. the petiole of a fern frond; plural rachides or rachises.
(Gr. rhachis, a backbone) Main axis of a spike; axis of fern leaf (frond) from which pinnae arise; in compound leaves, the extension of the petiole corresponding to the midrib of an entire leaf.

The rachis is the midrib of a leaf. It is usually continuous with the petiole and is often raised above the lamina (the leaf blade). On a compound leaf, the rachis extends from the first set of leaflets (where the petiole ends) to the end of the leaf.
The axis of a compound leaf or an inflorescences.
