The taxonomic value of fruit wing types in the order Apiales.
This study shows that structural data, when carefully examined, can provide valuable characters for delimiting monophyletic groups and can complement DNA with observable features to recognize andExpand
Revised generic delimitations for Oxypolis and Ptilimnium (Apiaceae) based on leaf morphology, comparative fruit anatomy, and phylogenetic analysis of nuclear rDNA ITS and cpDNA trnQ-trnK intergenic
Based on analyses of molecular data and corroboration with morphological and fruit anatomical data, new circumscriptions for the genera Oxypolis and Ptilimnium are formalized. Expand
A revision of the genus Choritaenia (Apiaceae)
The phylogenetic position of Choritaenia within the family Apiaceae remains unclear, but it is presumed to be related to the subfamily Azorelloideae, the only group where some members have dorsally compressed fruits with woody endocarps. Expand
The phylogenetic significance of the carpophore in Apiaceae.
A single carpophore and ventral vascular bundles not forming free carpophores are proposed to be the ancestral conditions in Apiaceae, while bifurcate carpophors with opposite vascular bundles are the derived state, present in most Apioideae. Expand
A revision of the genus Marlothiella (Apiaceae)
It was found that the general fruit morphology agrees with that typically found in Saniculoideae and other basally diverging taxa, and a detailed taxonomic revision is presented. Expand
Irregular vittae and druse crystals in Steganotaenia fruits support a taxonomic affinity with the subfamily Saniculoideae (Apiaceae)
Abstract The three-dimensional structure of the vittae and crystals of Steganotaenia araliacea was studied for the first time to allow a rigorous comparison with members of the subfamilyExpand
Unusual carpological characters in Marlothiella gummifera (Apiaceae)
Flowers and fruits of the monotypic Namibian endemic Marlothiella gummifera were examined to explore anatomical variation and to highlight problems associated with the homology of certain character states to find anatomical data to support their presumptive relationship based on molecular studies.
