Etymology
Oblata from the modern Latin oblatus, meaning 'somewhat flattened at the ends, oval, oblate'. Dilatata means 'widened', 'spread out', or 'dilated'. Syringa is derived from the Greek word syrinx, meaning 'pipe' or 'tube'. Named for the use of its hollow stems to make flutes. In Greek mythology, the nymph Syringa was changed into a reed.
