Phylogenetic placement of Cailliella praerupticola (Melastomataceae), a rare, monospecific lineage from Guinea, West Africa

“…The species is not at all resistant to the annual anthropogenic dry-season grassland fires that affect the vegetation of large areas in rural Guinea. On the southern Kounounkan Plateau and the Banga Guemey table mountain, C. praerupticola was found to be abundant and locally dominant in five patches of open shrubland vegetation, each 1 -4 hectares, at 650 -950 m elevation (Burgt & al. 2019).…”

“…Three soil samples taken under this vegetation contained no charcoal at all, although many wood pieces were present. These patches of shrubland may have been protected from fire because they are remote and surrounded by vertical rock cliffs and sub-montane forest (Burgt & al. 2019).…”

Ternstroemia guineensis (Ternstroemiaceae), a new endangered cloudforest shrub with neotropical affinities from Kounounkan, Guinea, W Africa

“…It has been conjectured that Ternstroemia guineensis and other point endemics that occur at the same location (e.g. Gladiolus mariae Burgt, Burgt & al. 2019), several of which are also in the process of being described, may be relics, and may once have been much more widespread over the sandstone table mountains of the Fouta Djallon, since these appear so similar in terms of ecology to the Ternstroemia location, excepting the presence of humans and the consequent high fire-frequency (Burgt & Haba cited in Couch & al.…”

“…Those recently discovered taxa specific to sandstone substrate in the S part of the Fouta Djalon are Gladiolus mariae Burgt (Burgt & al. 2019), Keetia susu Cheek (Cheek & al.…”
