Definition
Abruptly-pinnate describes a type of pinnate compound leaf that lacks a terminal leaflet, ending instead with a pair of leaflets or a tendril. It is similar to even-pinnate but specifies the sudden ending without the typical singular leaflet. Picture a ladder that suddenly stops at the top rung instead of having a final cap. This contrasts with leaves that taper to a point. It's like nature made a design choice to keep things short and sweet.
