The anatomical structure of the adult stem of S. corrugata is described to assist in the identification of liana stems used commercially. The main features are as follows: cambial variant of the divided- xylem-mass type, vessel dimorphism, non-lignified parenchyma bands in the wood, simple perforation plates, crystalliferous series in secondary xylem and phloem, simple sieve plates, sclerenchyma ring in the non-conducting phloem and measurements of xylem cells.
