Phylogeny of the subgenusEumitriain Tanzania [PDF]

open access: yesMycology, 2019
Several Usnea species in subgenus Eumitria (Parmeliaceae, lichenized Ascomycota) have been described from East Africa in the past decades. These have been based on morphology and chemistry data while molecular studies remain very limited. In this paper we are for the first time publishing phylogenetic analyses along with morphological and chemical data

Inflorescence structure in species of Scleria subgenus Hypoporum and subgenus Scleria (Sclerieae-Cyperaceae) [PDF]

open access: yesPlant Systematics and Evolution, 2009
The objective of this study was to realize a typology approach toward the inflorescences in Scleria in order to provide characters that would have potential use in further taxonomic and phylogenetic research and that would allow identification of the tendencies and processes that could have yielded the variations within Scleria inflorescences.
