remains known only from the type collection made by Keay in Dec. 1950 on a footpath across the Afi River in what is today the Afi River Forest Reserve of Nigeria. Reviewing Google Earth imagery for the site (placed at 6°15ˈ28.6&quot;N, 9°00ˈ32.71&quot;E, elev. 112 m, viewed June 2021) shows that the footpath has been upgraded to a motor road, and that clearing of the forest canopy is steadily taking place, confirming a report that dates from 6 Jan. 2016 and shows oil palm plantations, and open canopies indicative of logging, and these are confirmed by on-the-ground reports (https:// www.pandrillus.org/projects/afi- mountain-wildlifesanctuary/). Surface run-off due to these activities may have contributed to the extensive sediment deposits in the river that appear to be visible when the river is viewed by satellite imagery. Siltation of rivers is known to pose a threat to

That both species have clusters of several flowers surrounded by rosettes of flabellate leaves that form a protective funnel, borne on long stems may be convergence to this scenario. These rosettes may function to float on the surface and protect the flowers they contain from water droplets (observed by the first author for
