Figure 1:

Fruits of invasive Cucurbitaceae in Australia. The large fruit is Citrullus lanatus (camel melon), which has an average diameter of 7–10 cm. The smaller fruit is Cucumis myriocarpus (prickly paddy melon), which has an average diameter of 2–3 cm. The fruit of Citullus colocynthis (colocynth melon) is similar in size and appearance to that of C. lanatus, but C. colocynthis rind tends to have a mottled or mosaic pattern as opposed to the spotted or striped pattern seen on C. lanatus (Shaik et al., 2012).
