Schoenus bracteosus is a species of sedge endemic to the mountains of southern South Africa.
Schoenus bracteosus has firm primary inflorescence bracts that enclose its spikes and culm bases that are firm and non-viscous.[1] This species also has short hairs on its spikelet glumes.[1]
The flowering heads of S. bracteosus resemble those of Schoenus pictus, as they are firm and enclose its spikes;[2] however, S. pictus has viscous culm bases, whereas S. bracteosus lacks this character.[1]
The firm culm bases of S. bracteosus contrast with the membranaceous sheaths of other southern African Schoenus species, such as Schoenus aureus and Schoenus megacarpus.[2]
Plants in the southern African Schoenus clade are very difficult to identify, which is similar to other sedges. It appears that part of this problem is caused by the tendency of the southern African Schoenus to form hybrids with each other.[3] Preliminary evidence suggests that S. bracteosus might form hybrids with other southern African Schoenus species in both the Schoenus cuspidatus[4] and allies group and the Schoenus compar – Schoenus pictus and allies group.[2]
