Panicoideae is the second-largest
switchgrass
.
C4 photosynthesis evolved independently a number of times in the subfamily, which presumably had a C3 ancestor.[2]
Description
The ligule has a fringe of hairs. The inflorescence is branched around a common axis. The spikelets are all alike with two bisexual florets that are joined below the glumes (the outer floral envelopes). The lower glume is shorter than the spikelet.[3]
Systematics and taxonomy
Within the
Gynerieae were formerly placed in Arundinoideae, and the basal lineage, the "centothecoid clade" with seven tribes, was formerly seen as separate subfamily, Centothecoideae.[1]
