The name U. subquadripara has often been applied to material in Florida (e.g. FNA, vol. 25), its distinction from U. distachya has oft been questioned. Sosef (2016) chose to recognize only U. distachya, with the other as synonym, observing "an almost continuous grade" between the alleged forms.

Based on morphology this species was moved to Urochloa by Webster (1987) which is supported by DNA studies (Salariato et al. 2010; Delfini et al. 2023; Masters et al. 2024). This species is often placed in the genus Megathyrsus (Simon & Jacobs 2003), which is relatively deeply nested in a broader Urochloa clade. Webster (1987: 242) wrote "The compound branching pattern of the primary branches is the only basis for placing this species in Panicum. It has numerous spikelet, vegetative and anatomical characteristics in common with other species of Urochloa (as defined here) and its transfer is taxonomically essential."

Listed Status:	(Florida):Source - Plants in the Preservation of Native Flora of Florida Act. Chapter 5B-40, Florida Administrative Code. 1998, amended.
Endangered:	A species of plants native to the state that are in imminent danger of extinction within the state, the survival of which is unlikely if the causes of a decline in the number of plants continue, and includes all species determined to be endangered or threatened pursuant to the Federal Endangered Species Act of 1973, as amended.
Threatened:	Listed as Threatened Plants in the Preservation of Native Flora of Florida Act. Defined as species of plants native to the state that are in rapid decline in the number of plants within the state, but which have not so decreased in such number as to cause them to be endangered.

Listed Status: US	(U.S.) Source - List of Endangered and Threatened Wildlife and Plants under the provisions of the Endangered Species Act of 1973, as amended.
Endangered:	Any species which is in danger of extinction throughout all or a significant portion of its range.
Threatened:	Any species which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range.

AD:	Adaptive Species. Plant species designated as FAC or Upland by DEP, but commonly seen in the transition zone in limited numbers.
D:	Deep Species. Plant species commonly found in the deep zone, and designated either FAC or OBL by DEP.
OD:	Outer Deep Species. Plant species commonly found in the outer deep zone, and designated either FACW or OBL by DEP.
T:	Transition Species. Plant species commonly found in the transition zone, and designated either FACW or OBL by DEP.
U:	Upland Species. Plant species that are not expected to be seen in wetlands.

OBL:	Obligate wetland. Occurs almost always under natural conditions in wetlands.
FACW:	Facultative Wetland. Usually occurs in wetlands, but occasionally found in non-wetlands
FAC:	Facultative. equally likely to occur in wetlands or non-wetlands.
