Etymology: Microphyll is a plain technical coinage: it joins the Greek "mīkros", meaning small, to "phullon", meaning leaf, the root of the English suffix "-phyll". The first element comes from Ancient Greek "mīkro-", which later became the familiar English prefix "micro-". The two parts are a modern scientific pairing, built from classical materials rather than handed down from antiquity. In botany, a microphyll is a small leaf with a single unbranched vein, the kind found on clubmosses and their relatives. The term is used to distinguish these leaves from the larger, multiveined leaves of most other plants, which botanists call megaphylls.

Synonyms: small leaf, simple leaf
