28 genera, see text The Stipeae are a tribe of grasses within the subfamily Pooidae, with up to 600 described species.
[2] The defining morphological features of the Stipeae include single-flowered spikelets lacking a rachilla extension, and the lemmas (the external bract) have either a sharp point or a terminal awn (long bristle).
Some recent papers have analysed relationships within and between the genera,[6][7][8] but a complete analysis has not yet been performed.
Stipoid grasses use the C3 photosynthetic pathway and live in temperate areas worldwide.
[9] Known fossils date from the late Miocene.
