FIGURE 2. Cross-sections of the petiole at the proximal region. A. D. razakamalalae, a closed arc vascular bundle. B. D. orientalis an open arc. C. D. occidentalis, an open arc with slightly incurved ends. D. D. urschii, an open arc with one adaxial vascular bundles. E. D. bathiei, five vascular bundles. Cross-sections at the distal part of the petiole. F. Dalbergia pseudobaronii, 2 vascular bundles (1 adaxial and 1 abaxial). G. D. orientalis, 5 vascular bundles (2 adaxial and 3 abaxial). H. D. greveana, 9 vascular bundles (3 adaxial and 6 abaxial). I. D. urschii, 13 vascular bundles (5 adaxial and 8 abaxial). J. D. normandii, an open arc with one adaxial vascular bundle. Dot-filled areas= phloem, striped areas =xylem, tile areas sclerenchyma.
