Results for Microvictoria svitkoana from angiosperm‐wide molecular backbone analyses using maximum parsimony, based on 20 floral characters that could be scored for this fossil. The color coding, the time scale superimposed on the circular chronogram, and the sources of the backbone tree and morphological data set of extant taxa are as in Figure 1. The drawing in the lower right shows a reconstruction of the complex flowers of M. svitkoana (reproduced from Crepet et al., 2004, with permission of Wiley). The positions of the ANA grade (Amborellales, Nymphaeales, and Austrobaileyales) and of Calycanthaceae (Laurales), respectively, are indicated by orange bars in the circular chronogram. The pink circle indicates the approximate age of M. svitkoana according to Gandolfo et al. (2004).
