The name rachis is given to the axis of the spike, raceme and panicle, whether the axis is the main one or of the branch. The rachis of the inflorescence is usually cylindrical. In some grasses it is zigzag as in Pennisetum cenchroides. It is very much flattened in Paspalum scrobiculatum, but somewhat trigonous in Digitaria sanguinalis. In very many grasses the rachis is continuous, but in a few cases it consists of internodes or joints which disarticulate at maturity. Many species of Andropogon have such jointed rachises. Sometimes the joints become greatly thickened and the surface hollowed out, the spikelets fitting in the cavities as in Rottboellia and Manisuris.

In panicles, especially when they are diffuse, the primary branches may be disposed irregularly or in verticils on the main axis. For example in the panicle of Eragrostis Willdenoviana, the branches are irregularly disposed, whereas in Sporobolus coromandelianus the branches are verticillate. In both these grasses fleshy cushions are developed in the axils of the branches. These swellings help to spread out the branches especially at the time of anthesis. The branches at the top spread out earlier than those below.
