rachilla. (n.d.). Retrieved December 19th, 2018, from https://www.yourdictionary.com/rachilla
The stalk that bears the florets in the spikelets of grasses and similar plants, such as rushes and sedges. The rachilla often has a zigzag shape, with florets at each point at which the orientation of the rachilla turns.
It frequently extends downwards a little on the rachilla, forming with the latter a swollen callus, which is separated from the free portion by a furrow.
In many-flowered spikelets the rachilla is often jointed and breaks into as many pieces as there are fruits, each piece bearing a glume and pale.
Rachilla not produced beyond the flowers.
Spikelets oneto indefinite-flowered; in the one-flowered the rachilla frequently produced beyond the flower; rachilla generally jointed above the empty glumes, which remain after the fruiting glumes have fallen.
