Aristida congesta (tassel three-awn, Afrikaans: Aapstertsteekgras) is a species of grass native to all provinces of South Africa as well as Namibia, Botswana, Lesotho, Swaziland, and Mozambique. The SANBI Red List classifies it as "safe."[1]

SANBI mentiones two subspecies:

Aristida congesta Roem. & Schult. subsp. congesta Aristida congesta Roem. & Schult. subsp. barbicollis (Trin. & Rupr.) De Winter[2][2]

It is a thick perennial tussock that grows 10-75 cm high. The leaves can be flat or folded. The plumes are 3-20 cm long. The spikelets have uneven husks. The upper portion is the widest, at 6.5-10 mm. It can be found on deciduous woodland on rocky slopes and weathered areas.[3]
