Olaf Stapledon was aware of the fact that humans do not have enough surface area to support their metabolism via photosynthesis. His Plant-men were sessile during the day, and were connected to a much larger rosette of light-collecting leaves, from which they could detach and wander about at night.
Plant-derived sophont clades like Keruing also rely for most of their life on a much larger tree-like structure, which has a larger light-collecting surface and supports the mobile morph by secreting milk-like sap. For a short period of time the Keruing live independently, until they run out of stored energy and are forced to become rooted once more.
