Occurs in rainforests, often on steep slopes near streams and around soaks and on levees. It grows in leaf litter and gravelly loam, often among rocks. The plants are dormant throughout the drier months of the year, with the fleshy stems often covered by leaf litter. The growth of new stems commences with the summer rains. The small flowers do not self-pollinate and are believed to be splash-pollinated by falling raindrops.
Flowering period: January-May.
Previously confused with C. xanthochilum, which is from New Guinea and Indonesia.
