'sharp-lobed' originates from the combination of 'sharp,' meaning 'having a fine point or edge,' and 'lobed,' referring to a part of a leaf or organ that is rounded or divided.

'sharp-lobed' combines the Old English word 'scearp' (sharp) with the Middle English 'lobed,' which comes from the Old French 'lobe,' meaning 'a rounded projection.'

Initially, it described any pointed or acute projection, but now it specifically refers to leaves or organs with sharply defined lobes.
