Morphology
The noun phrase is directly compositional: 'bipinnate' specifies a particular (double pinnate) arrangement and 'leaf' names the plant organ, so the meaning 'a leaf that is pinnately divided twice' follows straightforwardly from the constituents. Although botanical vocabulary is specialized, if a learner knows the words 'bipinnate' and 'leaf' the phrase is immediately interpretable.
Etymology
The term bipinnate leaf comes from its parts bi- and pinnate: bi- means 'two' and pinnate means 'feather-like', so the main leaf is split and each of those parts is split again. That's why a bipinnate leaf means a leaf with two levels of small leaflets and a feathery look.
