Morphology

grass + fern

The meaning 'an epiphytic fern with a grassy appearance' is directly derivable from combining 'grass' and 'fern'—a straightforward noun-noun compound describing a fern that resembles or is associated with grass. This compositional pattern is common (especially in botanical naming) and a B1 learner who knows both constituents would readily infer the intended sense.

Etymology

The name grass fern comes from the plant's look. Its long, thin leaves look like grass even though it is a fern that often grows on trees, so the name means a fern that 'looks like grass'.
