Morphology

lamellate + placentation

The phrase is morphologically and semantically compositional: 'lamellate' means having thin plate-like lamellae and 'placentation' refers to the arrangement/attachment of ovules, so together it denotes a placentation characterized by lamellae. Although the vocabulary is technical (and 'lamellate' may be rare), the adjective+noun structure makes the meaning directly derivable for a learner who knows the constituent words.

Etymology

Lamellate placentation comes from the image of thin 'plates' growing into a flower's ovary that hold the 'ovules'. lamellate means plate-like and placentation describes how the ovules attach, so the phrase explains ovules attached to thin plate-like parts inside the ovary.
