Figure 1 in Inclusion of Ihlenfeldtia and Odontophorus in Cheiridopsis (Ruschioideae: Aizoaceae) and insights into generic and subgeneric circumscription in the Conophytum clade
Figure 1. Majority-rule consensus tree from Bayesian analysis of six plastid markers, indicating phylogenetic relationships in the Conophytum clade. Posterior probability values>0.5 are indicated above the branches. Jackknife support values and bootstrap supports>5%, from the maximum parsimony and maximum likelihood analyses, are indicated below the branches. Brackets indicate the placement of taxa and clades discussed, with embedded genera indicated in bold.
Figure 8 in Inclusion of Ihlenfeldtia and Odontophorus in Cheiridopsis (Ruschioideae: Aizoaceae) and insights into generic and subgeneric circumscription in the Conophytum clade
Figure 8. Leaf and floral characters of Cheiridopsis and Conophytum. (A) New leaves of Conophytum wettsteinii breaking out of their papery sheath, with a magenta flower; (B) partial sheath enclosing the emerging leaf pair, with a magenta flower, in Cheiridopsis glomerata; (C) leaves of Cheiridopsis meyeri completely enclosed by a white papery sheath during the dormant period, indicated by the arrow; (D) leaves of Conophytum uviforme completely enclosed in a sheath during the dormant period, indicated by the arrow; (E) Cheiridopsis purpurea with the partial sheath, common to many Cheiridopsis spp. which only encloses part of the leaves during the dormant period; (F) Cheiridopsis aspera with the prominent rough leaf surface often found in subgenus Odontophoroides.

Figure 4. Character reconstruction of sheathing type and capsule type on the majority-rule consensus tree from the Bayesian inference analysis. (A) Sheathing genera and sheath type (partial and complete) (Character 1; Appendices 4 and 5) in the Conophytum clade reconstructed in five steps, a complete sheath refers to species where the sheath fully encloses the emerging pair during the dormant period (Fig. 8C, D) and a partial sheath only encloses part of the emerging leaf pair during dormancy (Fig. 8B, E); (B) capsule type (simple and complex) (Character 2; Appendices 4 and 5) in the Conophytum clade reconstructed in three steps, simple capsules do not include internal structures such as covering membranes or closing bodies (Fig. 7B), whereas complex capsules include covering membranes and usually closing bodies (Fig. 7D).
