Comment
A leptome is composed of only leptoids (PO:0025033). Found in bryophytes, in non-vascular shoot axes such as a gametophore axis or seta (PO:0030032) or in the midrib of a non-vascular leaf. Often surrounding a central hydrome. May function in the conduction of organic substances, similar to phloem in vascular plants.
