Conservation
The extent of occurrence is over 20,000 km2 and the number of locations is more than ten. Since the species has inconspicuous inflorescences, it is easily overlooked by collectors; therefore it may be more common than the herbarium collections suggest. In the Sula Mountains in Sierra Leone, where the species was specifically searched for, it was found in seven locations. It is likely that there are many more locations in the Sula Mountains. The species is largely immune to human interference because of its habitat preference. Schoenoplectiellaoxyjulos is classified here as Least Concern (IUCN 2011).
Distribution
West and Central Tropical Africa: Guinea, Sierra Leone, Nigeria, Cameroon, Central African Republic, Sudan.
Ecology
Seasonally inundated rock pools on inselbergs and hills with grassland or wooded grassland vegetation; alt. 650 – 800 m.
Type
Type: Sierra Leone, Kambia to Kukuna, Morton & Gledhill SL 27 (holotype K!; isotype SL).
