[121] The term solenostele, first used by Van Tieghem and revived by Gwynne-Vaughan, may be applied to a stem in which the vascular tissue has the form of a hollow cylinder with phloem and endodermis on each side of the xylem. As each leaf-trace is given off the continuity of the vascular tube is interrupted. See Gwynne-Vaughan (01) p. 73.
