Explain the string "Leaves-only"

[milotype]

Please explain the meaning of the string "Leaves-only" in order to translate it.

[KoiKoneessa]

I think it's leaves/noun, not leaves/verb.

Any cell can be a stem from which leaves sprout, and can also be a leaf on another stem.

Sorry, English is weird. Leaf > Leaves because the /s/ is vocalized, so the /f/ breaks to a /v/ to make it easier to say.
