Relating to or located on the outer surface of the phloem (the tissue in plants that transports sugars and other compounds).
From epi- (upon) + phloem (bark, plant tissue) + -al (adjectival suffix), from Greek phloios (bark). This botanical term describes the positioning on the external layer of nutrient-transporting tissue.
Plants have a nutrient highway called phloem, and epiphloedal structures sit right on top of it like tiny shops on the side of a very important road!
