It has been suggested that southern Africa is the origin of the predominantly herbaceous Apiaceae subfamily Apioideae and that the woody habit is plesiomorphic. We expand previous molecular phylogenetic analyses of the family by considering all but three of the approximately 38 genera native to southern Africa, including all genera whose members, save one, have a woody habit. Representatives of five other genera are included because they may be closely related to these southern African taxa…

A molecular phylogeny of Chinese Apiaceae subfamily Apioideae inferred from nuclear ribosomal DNA internal transcribed spacer sequences
TLDR
The Hengduan Mountains of the Sino-Himalayas are rich in endemic species of Apiaceae subfamily Apioideae and to ascertain their higher-level phylogenetic placements within the subfamily, 106 accessions were examined including the Chinese endemic genera Changium, Cyclorhiza, Notopterygium, Nothosmyrnium, and Sinolimprichtia.
A Revision of the South African Genus Hermas (Apiaceae)
Abstract The morphologically and phylogenetically anomalous genus Hermas is revised and nine perennial species are recognized, all endemic to mountain slopes within the Cape Floristic Region of…
Phylogenetic analysis of nrDNA ITS sequences reveals relationships within five groups of Iranian Apiaceae subfamily Apioideae
TLDR
Opopanax and Smyrniopsis, traditionally treated in two tribes, are confirmed as monophyletic sister groups in the Apioid superclade.
Ezosciadium (Apiaceae): a taxonomic revision of yet another early diverging South African apioid genus
TLDR
The hitherto poorly known Cape endemic genus Ezosciadium (Apiaceae) is revised and was found to form part of an early diverging lineage within the subfamily Apioideae, sister group to the Annesorhiza clade and possibly also closely related to the genera Molopospermum and Astydamia.
Molecular Phylogenetics of Ligusticum (Apiaceae) Based on nrDNA ITS Sequences: Rampant Polyphyly, Placement of the Chinese Endemic Species, and a Much-Reduced Circumscription of the Genus
TLDR
Relationships among those other species traditionally accommodated in Ligusticum, especially those of the Chinese LIGusticum clade, are far more complex than previously realized and will require further study utilizing the framework phylogeny presented herein before their taxonomy can be revised to reflect evolutionary relationships.
The demise of subfamily Hydrocotyloideae (Apiaceae) and the re-alignment of its genera across the entire order Apiales.
New insights into the phylogeny and taxonomy of Chinese Physospermopsis (Apiaceae)
TLDR
This study found that Physospermopsis is monophyletic, nested in Pleurospermeae of Apiaceae, sister to PleuroSpermum, and proposes that the PhysOSpermopsis clade should be replaced by the East Asia Clade.
Molecular phylogenetics of Pimpinella and allied genera (Apiaceae), with emphasis on Chinese native species, inferred from nrDNA ITS and cpDNA intron sequence data
TLDR
Pimpinella is resolved as non-monophyletic, yet the monophyly of a Piminella ‘ core group ’ in tribe Pimpinelleae is strongly supported, and most Chinese native Pimpineella species fall within this core group; the other Chinese species examined appear in four other tribes within the subfamily.
Major clades within Apiaceae subfamily Apioideae as inferred by phylogenetic analysis of nrDNA ITS sequences
TLDR
An ITS-based classification of the Apiaceae subfamily Apioideae is proposed that enables direct and precise references to specific groups and facilitates sampling and hypothesis testing in future systematic studies.
The evolutionary history of Eryngium ( Apiaceae , Saniculoideae ) : Rapid radiations , long distance dispersals , and hybridizations
TLDR
Dispersal-vicariance analysis indicates that Eryngium and its two subgenera originated from western Mediterranean ancestors and that the present-day distribution of the genus is explained by several dispersal events, including one trans-Atlantic dispersal.

Phylogenetic analysis of chloroplast rps16 intron sequences reveals relationships within the woody southern African Apiaceae subfamily Apioideae
TLDR
The resultant phylogenies indicate that the apioid genera Polemanniopsis and Steganotaenia form a clade sister to Apiaceae subfamily Saniculoideae and the African genera Anginon, Dracosciadium, Glia, Heteromorpha, and Polemannia also comprise aClade and likely represent the most basal elements within Apioideae.
Circumscription of Apiaceae tribe Oenantheae
Molecular systematics of Old World Apioideae (Apiaceae): relationships among some members of tribe Peucedaneae sensu lato, the placement of several island-endemic species, and resolution within the apioid superclade
TLDR
Comparative sequencing of the two internal transcribed spacer regions of nuclear ribosomal DNA was carried out to examine evolutionary relationships among representatives of Old World Apiaceae (Umbelliferae) subfamily Apioideae and confirmed the monophyly of Drude's tribe Echinophoreae.
Phylogenetic relationships in Bupleurum (apiaceae) based on nuclear ribosomal DNA its sequence data.
TLDR
These phylogenetic results do not agree with any previous classifications of the genus Bupleurum, and all endemic north-west African taxa are included in a single unresolved but well-supported clade, and the low nucleotide variation of ITS suggests a recent radiation within this group.
Higher level relationships of Apiales (Apiaceae and Araliaceae) based on phylogenetic analysis of rbcL sequences
TLDR
Clarification of phylogenetic relationships has concomitantly provided insights into trends of morphological evolution, and suggests that the ancestral apialean taxon was probably bicarpellate, simple-leaved, woody, and paleotropical.
A phylogeny of Apiaceae tribe Scandiceae: evidence from nuclear ribosomal DNA internal transcribed spacer sequences.

Phylogenetic analysis of apiaceae subfamily apioideae using nucleotide sequences from the chloroplast rpoC1 intron.
TLDR
Trees derived from rpoC1 intron sequences estimated using maximum parsimony or maximum likelihood methods are of essentially similar topology, and indicate that subfamily Apioideae, with Heteromorpha as its most basal element, is monophyletic and is a sister-group to Eryngium, the only representative examined.
A PRELIMINARY ANALYSIS OF EVOLUTION OF AFRICAN AND MADAGASCAN APIACEAE

TLDR
These genera are clearly central to a better understanding of the early evolution of the Apiaceae and also to the ultimate improvement of Drude's (1898) classification system.
Evolutionary Patterns in Apiaceae: Inferences Based on matK Sequence Data
TLDR
Topology, along with evidence from morphology, anatomy, geographic distribution, and insertions and deletions in matK sequences, suggests that subfamily Apioideae may have originated in southern Africa from woody, simple-leaved ancestors.
The phylogenetic and taxonomic position of Lilaeopsis (Apiaceae), with notes on the applicability of ITS sequence data for phylogenetic reconstruction
TLDR
As alignment of the ITS sequences is problematic even within the Oenanthe clade, the reliability of phylogenies on the basis of ITS data of higher taxonomic levels in the Apiaceae is questioned, but for phylogenetic analysis within Lilaeopsis ITS sequences may prove useful and unproblematic.
