The radial longitudinal section enabled us to determine the phloem radii, which are heterocellular, with 4-5 marginal rows of high upright cells, the multiseriate parts composed of
procumbent cells having intercellular spaces (Fig.
Clearly, considerable opportunity is available for selection within the collection to produce populations with desirable agronomic traits such as a semi-upright growth habit for hay production or a
procumbent growth habit to improve grazing tolerance.

Rhizomes are suberect to
procumbent or scandent, sometimes short-creeping, rigid, densely scaly.
sectio Repentia Main axis
procumbent Yoshida or decumbent forming secondary haptera on the ventral face; primary axes branched on the dorsal face of main axis; receptacles compressed to flattened.
Absent storied structure, heterocelular ray, body composed of
procumbent cells with a row of upright and /or squared marginal cells, and crystals were not observed.
Rays are 4 (2-6) series, heterogeneus, formed by tile and
procumbent cells, moderatly numerous, extremely low and medium width.
Stachys schiedeana Schlecht.), Lamiaceae is an aromatic, perennial,

The Canellaceae are anomalous within the Magnoliales in that they have unilateral paratracheal parenchyma, they lack apotracheal parenchyma, their vessel-ray parenchyma pits are half-bordered and similar to intervessel pits, and they commonly have crystals in
procumbent and upright ray cells, a feature not seen in any other family of the Magnoliales.
The most notable differences are found in the perfect flowers and uniseriate homocellular rays composed of
procumbent cells in Asteropeia versus the apetalous flowers and uniseriate homocellular rays composed of mostly upright or square cells in Physena.
