The Arundinoideae are a subfamily of the true grass family Poaceae with around 40 species, including giant reed and common reed. Unlike many other members of the PACMAD clade of grasses, the Arundinoideae all use C3 photosynthesis. Their sister group is the subfamily Micrairoideae.

Brachypodium is a genus of plants in the grass family, widespread across much of Africa, Eurasia, and Latin America. It is classified in its own tribe Brachypodieae.
Axonopus is a genus of plants in the grass family, known generally as carpet grass. They are native primarily to the tropical and subtropical regions of the Americas with one species in tropical Africa and another on Easter Island. They are sometimes rhizomatous and many are tolerant of periodic submersion.
Arthropogon is a genus of South American and Caribbean bunchgrass plants in the grass family.

The PACMAD clade (previously PACCMAD, PACCAD, or PACC) is one of two major lineages (or clades) of the true grasses (Poaceae), regrouping six subfamilies and about 5700 species, more than half of all true grasses. Its sister group is the BOP clade. The PACMAD lineage is the only group within the grasses in which the C4 photosynthesis pathway has evolved; studies have shown that this happened independently multiple times.
Cenchrus distichophyllus is a grass species native to Cuba.
Altoparadisium is a genus of bunchgrass plants in the grass family. The species are native to Brazil and Bolivia in South America.
Canastra is a genus of bunchgrass plants in the grass family. Its species are endemic to Brazil.
Steyermarkochloeae is a tribe of the Panicoideae subfamily in the grasses (Poaceae), native to tropical South America. There are only two species in two genera, Arundoclaytonia and Steyermarkochloa. The tribe probably belongs to a basal lineage within the subfamily. Species in this tribe use the C3 photosynthetic pathway.
Tristachyideae is a tribe of the Panicoideae subfamily in the grasses (Poaceae), native to tropical and subtropical regions of Africa, Asia, and South America. There are around 70 species in eight genera. The tribe belongs to a basal lineage within the subfamily, and its genera were previously placed in tribes Arundinelleae or Paniceae, subfamily Arundinoideae, or the now-obsolete subfamily Centothecoideae. Species in this tribe use the C4 photosynthetic pathway.
