Other claims from this paper (13)

Observation Polycarpon is polyphyletic.
Observation Sphaerocoma is sister to Pollichia and has intraspecific variation.
Observation Sanctambrosia falls within Spergularia.
Observation Preliminary data suggest Polycarpaea is polyphyletic.
Observation Caryophyllaceae emerged during the Paleocene, according to preliminary data.
Observation Major extant Caryophyllaceae lineages originated in the Oligocene and diversified later.
Method / resource Molecular identification resolved around 50% of Moroccan medicinal roots to species level.
Method / resource Molecular identification resolved an additional 30% of Moroccan medicinal roots to genus level.
Observation Sphaerocoma species were merged into one species with two subspecies.
Mechanism Sanctambrosia is probably due to long-distance dispersal.
Mechanism Inbreeding depression probably caused Sanctambrosia woody habit and gynodioecy.
Observation Sanctambrosia manicata was transferred to Spergularia.
Method / resource Molecular identification of traded medicinal roots had a lower success rate than theoretical studies.
