Schoenus galpinii
Schoenus galpinii is a species of sedge endemic to eastern southern Africa. Description. The main distinguishing morphological character of "S. galpinii" is that its primary inflorescence bracts, as well as prophyll and glume mucros are less-developed (often shorter or lacking) compared to other closely related southern African "Schoenus" species. The distribution of "S. galpinii" differs from most other species in the "Schoenus cuspidatus" and allies group, except "Schoenus graciliculmis" and "Schoenus limosus". "Schoenus galpinii" has cuspidate spikelets compared to the aristate spikelets of the other two species. The species that morphologically most resembles "S. galpinii" is "S.  cuspidatus", which has more prominent inflorescence bracts, prophyll mucros and glume mucros compared to "S. galpinii". The more prominent bracts and mucros of "S. cuspidatus" make it appear more 'bearded' compared to "S. galpinii". Similar to other sedges, plants in this group are very difficult to identify. It appears that part of this problem is caused by the tendency of the southern African "Schoenus" to form hybrids with each other. It is not known whether "Schoenus galpinii" forms hybrids with other southern African "Schoenus" species. Taxonomy. "Schoenus galpinii" is a species in family Cyperaceae, tribe Schoeneae. Other notable genera in  tribe Schoeneae include "Lepidosperma", "Oreobolus", "Costularia", "Tetraria" and "Gahnia". The most closely related species to "S. galpinii" are other southern African "Schoenus" species, specifically, species in the "S. cuspidatus" and allies group. Southern African "Schoenus" were once classified as "Tetraria"; however, based on molecular and morphological differences, we now know that the two groups are evolutionary distinct. To ensure that this group of sedges is monophyletic (i.e. the genus only has closely related species), several species of "Epischoenus" and the southern African "Tetraria" were transferred into "Schoenus". In the field, the southern African "Schoenus" can be distinguished from "Tetraria" species  by their lack of stem leaves and the absence of reticulate sheaths at the bases of the flowering stems. Distribution and habitat. "Schoenus galpinii" is a sedge species that generally grows in grassland habitats on mountain slopes in the Kwazulu-Natal and Eastern Cape Provinces of South Africa. This species has also been collected from eastern regions of Lesotho.
