is known from one site on the Mayan Kouré River, an affluent that, 5 km to the north joins the Konkouré, one of Guinea’ s largest southward draining rivers. About 25 km upstream of that junction, at Donkheya, the Konkouré is dammed for a hydroelec- tric project. The reservoir extends upstream for 52 km (measured on Google Earth from imagery dated 21 Jan. 2015, downloaded 13 May 2018). This reservoir also extends up several of the affluents. About 20 km downstream of the same junction a new hydroelectric project was opened in 2017 (under construction in the Google Earth imagery of 21 Jan. 2015). The risk is that the reservoir of this project extends upstream a similar distance to that of Donkheya affecting the hydrology of its affluent, on the Mayan Kouré. Moreover, additional hydroelectric projects are planned on the Konkouré. The Konkouré river and its affluents remain almost completely unsurveyed for their plant species including

. Updating this before submission of this paper two years later, CNES Airbus imagery dated 11 Nov. 2018 viewed on Google Earth shows that as feared, the new reservoir on the Konkouré had already filled nearly up to the junction with its affluent, the Mayan Kouré. It is possible that by now, June 2021 the type location of
