SUMMARY Translocation of 14 C labelled products of photoassimilation within Ascophyllum nodosum tissue with or without epiphytic Polysiphonia lanosa was found not to occur. Aerial P. lanosa contains several water‐soluble sugars but only sodium mannoglycerate was radioactive following a 1h pulse in ( 14 C) bicarbonate. Evidence is presented to show the presence of this compound in the rhizoids of P. lanosa and to demonstrate that its metabolism here differs from that in aerial parts of the plant. The ability of aerial parts of P. lanosa to utilize exogenously supplied ( 14 C) glucose has been demonstrated.
