IPA: /ˌjuːnɪˈfoʊliəˌleɪt/

Having a single leaflet, even though it is part of a compound leaf structure.
The unifoliolate leaves of the plant are easy to identify due to their unique shape.
Unifoliolate is formed from "uni-" (meaning one) and "foliolus" (from Latin, meaning leaf or leaflet) and the suffix "-ate" (indicating a state or condition). The word describes a plant or leaf that has a single leaflet or leaf.
Think of 'one' ('uni-') leaf ('foliolus') to remember that 'unifoliolate' refers to a plant with a single leaflet.
