Schoenus adnatus is a species of sedge endemic to mountainous locations in southern regions of South Africa.[1]
Schoenus adnatus is a species of southern African Schoenus that shares traits characteristic of the Epischoenus group of Schoenus.[1]
The main important character distinguishing S. adnatus from other similar species is that the spikelet receptacle is adnate to the lowest (basal) glume (bract).[1]
The growth forms of Schoenus gracillimus and Schoenus schonlandii similar to that of S. adnatus; however, neither of these two species have a spikelet receptacle that is adnate to the lowest glume.[1]
Schoenus adnatus can sometimes be slightly hairy, but its spikelets and culms are much less hairy that those of Schoenus crinitus. Another difference between the two species is that the culms of the S. adnatus are narrower (≤ 5 mm) than those of S. crinitus (≥ 6mm).[1]
The southern African Schoenus tend to form hybrids with each other, which partially explains why they can be difficult to identify.[2] It is impossible to determine if S. adnatus forms hybrids with other southern African Schoenus species because of a lack of evidence.[1]
