Bombax ceiba
Saigon, one of a number of older names for Ho Chi Minh City, may be derived from "Sài" (Sino-Vietnamese "palisade" etc.) and the Vietnamese name for the Kapok tree "(bông) gòn", although, in this instance, the tree intended may well be, not the New World "Ceiba pentandra", but the Old World "Bombax ceiba".
