Parsimony tree for Cucumis based on the combined chloroplast and nuclear data and rooted on Muellerargia as in Fig. 1. Parsimony bootstrap values (> 75%) based on 1000 replicates above branches and ML bootstrap values from 100 replicates below branches. Species on pale grey background occur in Africa (C. prophetarum extends into India); the clade marked in grey-green occurs in Australia, the Malaysian region, Indochina, China, and India (Mukia maderaspatana extends into the Yemen and sub-Saharan Africa; see Table 1 for geographic ranges); the natural range of melon (C. melo) is unclear. Information on chromosome numbers is from the Index to Plant Chromosome Numbers database available online at the Missouri Botanical Garden's web site.
