to distinguish it from morphologically close species seem to be more variable than suspected. We observed that the distichous arrangement of leaves and the absence of ramification of the blade are constant throughout the recently collected material, but the presence and shape of stipules, the presence and size of the sheath, and the length and overall shape of the blade can vary. We have noticed three morphogroups occurring in Gabon: one characterized by having all leaves of reproductive rosettes without stipules, with sheaths enlarged but folded and imbricate, and with ensiform (laterally flattened) leaf blade; another group characterized by most leaves with 1-2 stipules at base, with sheaths enlarged but less folded, and leaf blades less obviously ensiform; and a third group with enlarged sheaths bearing obscure (rounded) stipules, and with leaf blade widening on their apical portion, most of them showing a conspicuous midrib. Nevertheless, we are reluctant to name and describe these morphogroups as separate entities, as all characters mentioned here show continua, including in collections from West Africa. Morphological continua between these character states can sometimes even be observed on single shoots, with strong polymorphism of leaves depending on their position relatively to the spathellae. Most of the Gabonese collections studied could be assigned to either one of the three morphogroups based on the observation of the numerous individual shoots they each comprise (usually several dozens or even hundreds of shoots), but all of them also comprise a significant portion of shoots displaying intermediate character states. We believe it is best for now to consider
