Abbreviations: proportion Of the adaxial epidermis (ADE%); proportion of abaxial epidermis (ABE%); proportion of chlorophyll parenchyma (PAR%); proportion of the sum of total phloem in the leaf (PHT%); proportion of the phloem in one vascular bundle (PHVB%); proportion of the bundle sheath in the vascular bundle (BS%); proportion of the vascular bundles in the leaf (VB%); proportion of the sum of total xylem in the leaf (XLT%); proportion of the phloem in one vascular bundle (XLVB%); proportion of the sum of total fibers in the leaf (FBT%), proportion of the fibers in one vascular bundle (FBFV%).
Areas of the tissues were obtained as follows: the adaxial surface of the epidermis, the abaxial surface of the epidermis, the chlorophyll parenchyma, the sum of the phloem areas, the average phloem area in one vascular bundle, the sum of the areas of the vascular bundle sheaths, the sum of the areas of the vascular bundles, the sum of the areas of the xylem, the average xylem area in one vascular bundle, the sum of the area of fibers, the average fiber area in one vascular bundle, and the whole leaf area captured in the image using square micrometers as the measurement unit.
The proportion of vascular bundle sheaths was higher in U.
The leaf of MRCA was possibly flat, with leaf margin also flat, with regular arrangement of vascular bundles in the midrib, without crypts, without tall or voluminous epidermal cells, without thick cuticle on the adaxial face, with uniseriate epidermis, with stomata and glandular trichomes only on the abaxial face, with inconspicuous indumentum, with bifacial thin mesophyll, without hypodermis or colorless parenchyma in the middle of mesophyll, without numerous vascular bundles and bundle sheath extensions and with chlorophyll parenchyma throughout the mesophyll.
8 Leaf anatomical characterization--mesophyll and bundle sheath extensions, a-c Minasia scapigera.
There is bundle sheath around the vascular bundles.
Bundle sheaths are one layered, thin walled parenchymatatic cells.
Instead of partitioning metabolites in space (between mesophyll and bundle sheath
cells), CAM plants use PEP carboxylase to fix the carbon into malate, which is then stored until the next day, when the carbon is released and refixed in normal Calvin cycle metabolism.

2; dotted line), the linear regression gave an intercept value of -4.4 and a less negative slope, suggesting increased leakage of [CO.sub.2] from the bundle sheaths
Bundle sheath is single and complete around VBs (Table 1; Fig.
All the species have complete and single bundle sheath around the VBs except the median vascular bundle in which sometimes there are interruptions in sheath on the lower surface.
