The stem closer showing the petiolar sheath and cataphyll. A petiolar sheath is a pair of wing-like sheaths on the side of a previous petiole from which the next petiole and leaf emerge. A cataphyll is similar but is a bract-like modified leaf which surrounds any newly developing leaf to protect the emerging blade as it develops. A cataphyll may be unribbed as well as single or double ribbed and in some genera may have important characteristics used to determine the species.

Thanks for any input!
