Data from: A giant spurrey on a tiny island: on the phylogenetic position of Sanctambrosia manicata (Caryophyllaceae) and the generic circumscriptions of Spergula, Spergularia and Rhodalsine
The only member of the generally herbaceous family Caryophyllaceae that may grow to a small tree is Sanctambrosia manicata, endemic to remote San Ambrosio Island, off the coast of Chile. The monospecific Sanctambrosia has been suggested to be closely related to Spergula and Spergularia (spurreys) on the basis of morphology, despite its treelike habit and gynodioecy. A plastid DNA dataset (ndhF, rps16, trnL-F) is used to investigate the relationships of Sanctambrosia and other members of Sperguleae. Sanctambrosia manicata is shown to be nested in a clade of New World and Australian Spergularia and the new combination Spergularia manicata is proposed. The volcanic San Ambrosio has been estimated to be almost three million years old, and S. manicata presumably evolved its treelike habit and gynodioecy over a short period of time. Spergula and Spergularia are monophyletic and recognizable by their number of carpels, five in Spergula and three in Spergularia. Spergularia fallax, which resembles Spergula in leaf characters, is shown to be sister to all other species of Spergularia. Minuartia subg. Rhodalsine belongs in Sperguleae and is sister to Spergula and Spergularia together, which supports the recent resurrection of Rhodalsine at the generic level.

FIGURE 2. PCA analysis: (A) distribution of individuals in the ordination space (circles ‒ black-seeded plants, X-marks ‒ brown-seeded plants), (B) fit of the 21 morphological characters to the ordination axes. The first and the second ordination axes explain 24.3% and 16.4% of the total variation, respectively.

FIGURE 4. Classification tree of the individuals of the black-seeded and brown-seeded morphotype of Spergularia echinosperma. If a character value matches the classification rule, the determination continues to the left branch, otherwise to the right branch. Lengths of the branches correspond to the relative discriminatory powers of the respective rules. The group names at the terminal nodes indicate the predicted classification of a particular node, whereas the numbers separated by slashes indicate actual membership of samples classified to a particular node (black/brown).

FIGURE 7 in Taxonomy and evolutionary diversification of the Central European endemic Spergularia echinosperma (Caryophyllaceae)
FIGURE 7. Characters measured on the seeds (A) and surface papillae (B). The black curved line specifies the part of the seed circumference where the density of papillae was determined. The longitudinal border of this part is a plane halving the vector of maximal seed length and perpendicular to it (indicated by a dotted line). The character PapRat was computed by dividing the width of the papilla head by the width of the neck.
