Rays lignify when crossing the fiber bands; C, Detail of the variant phloem of Adenocalymma flaviflorum. Sieve tubes typically with two companion cells, each lying on a different corner. Axial parenchyma as the background tissue; D, Adenocalymma divaricatum variant phloem. Fibrous-phloem. Sieve tubes in tangential arrangement. Rays with portions lignified and non-lignified; E, Adenocalymma comosum variant phloem. Semi-fibrous phloem. U-shaped fiber bands.

FIG. 17. — Secondary phloem of Adenocalymma mirabile: A-C, Adenocalymma mirabile transverse-sections; A, regular phloem. Thin to thick fiber bands. Periderm with stratified phellem, with alternating thin and thick-walled, lignified cells. Phelloderm thick, with over 3 cell layers; B, overall view of the variant phloem. Non-fibrous to semi-fibrous phloem. Fiber bands thin to thick, U-shaped in several portions. Limiting ray lignified to both xylem and phloem face; C, detail of the variant phloem.
