What does Chrysanthe mean?
Greek compound of 'chrysos' (gold) and 'anthos' (flower), meaning 'golden flower' — the root of 'chrysanthemum'. Literal gold element combined with flower.
What does Nerida mean?
Associated with the Greek Nereids, the sea nymphs who were daughters of the sea-god Nereus, and with Greek neros 'water'. The name itself appears to be a relatively modern coinage (a popular Australian claim of an Aboriginal 'water lily' meaning is poorly documented), so treat the sea-nymph sense as its best-supported reading.
