FIGURE 4. The single most parsimonious cladogram showing the quantitative characters. Below branches the characters and their optimized states are shown, synapomorphies in bold. Quantitative characters were transformed from the standardized to raw data for a better understanding (Appendix 2). Abbreviations as in Fig. 3.

FIGURE 3. The single most parsimonious cladogram showing the qualitative characters. Numbers above branches are Jacknife support values (absolute/GC). Numbers below branches are Bremer support values (absolute/relative). A and B are the two main clades of Smallanthus. Black circles are synapomorphies and white circles are homoplasies. Numbers above circles indicate character number and numbers below circles indicate character state according to Appendix 2.

Data from: Phylogenetic studies in Smallanthus (Millerieae, Asteraceae): a contribution from morphology
We present a cladistic analysis of all the species of Smallanthus. Six taxa within Rumfordia, Ichthyothere, Acanthospermum and Tridax served as outgroups. We evaluated the monophyly and the relationships between the species of Smallanthus through a maximum parsimony study based on morphological data. The matrix included 31 qualitative characters from floral and vegetative parts of the specimens. We also explored the phylogenetic significance of treating quantitative characters as continuous. Only one most parsimonious tree was obtained. In agreement with previous phylogenetic studies based on molecular data, we recovered a monophyletic Smallanthus. The presence of ray corollas, densely pubescent at the base, was the synapomorphy that defined Smallanthus. Smallanthus microcephalus and two other major clades were recovered. The first clade included S. glabratus, S. fruticosus, S. jelskii and S. pyramidalis, while the second one contained the remaining species of Smallanthus. The analysis recovered one species of Rumfordia as sister to Smallanthus. We present a new combination, Smallanthus cocuyensis, based on morphological analysis of the type specimen.
