What is the plant's leaf arrangement ?

Basal Leaves clustered at the base, next to the ground.

Whorled Multiple leaves, at least 3, usually arranged more or less evenly around a stem, clustered above ground level.   Whorls just at ground level are called "Basal".

Opposite Leaves arranged usually in pairs on opposite sides of the stem, although the last leaf may be a single leaf at the end of the stem.   (When there are more than 2 leaves attached at the same point on the stem, this is referred to as a Whorl.)

Alternate Single leaves arranged so they alternate from one side of the stem to the other side.   For purposes of classification, a plant that exhibits leaves both alternately and occasionally oppositely on the same stem should be treated as an alternate.
