(sclerocarp) is the predominantly sclerenchymatous layer that includes and surrounds the locular envelope(s), uniting them into a common structure known as the "stone." This tissue, composed mainly of tortuous tracts of fibers, but sometimes also of brachyselereids, forms the main part of the septa as well as the external wall of the stone.
The sclerenchymatous strands on the upper surface are much shorter than strands on the lower surface.
is characterised by a porous texture, patterning of sclerenchymatous tissue and lobate epidermal cells of the inner endocarp.
The preserved ridges and striations in specimens 002-339, 004-263, and 985-202 represent impressed cortical sclerenchymatous fibres or bundles in support of medullosalean axes or stems (see Zodrow 2002).
He suggests that photosynthetic capacity (and rubisco levels) per unit leaf mass and the proportion of leaf mass in mesophyll cells versus epidermal, vascular and sclerenchymatous cells may be positively associated with relative growth rates.
Monocot stems counteract the loss of a vascular cambium by producing vascular tissue in a wider cylinder of scattered bundles embedded within a parenchymatous (or sclerenchymatous) background.
###Jinyuan###Four or five layers of irregular globular unidiomatic lignified sclerenchymatous cells###Fig.
When present, they only occur in such aerial organs as the leaves and scapes of the amphibious species in the form of bundles of sclerenchymatous extravascular fibers (Figure 7) or of vascular pericyclic fibers involving completely the vascular bundles, as in Oxycaryum cubense (Figure 4); they can also form bands of sclerenchymatous pericyclic fibers limiting the vascular cylinder as in the scapes of the emergent species Habenaria repens and Eichhornia paniculata (Figures 8-9).
The primary rachis is preserved for a length of 22 cm, and is 1 cm wide with longitudinal striations that represent medullosalean sclerenchymatous fibres (imparting strength to the frond structure).
The seed coat, however, is unlike any in Ammannia in having sclerenchymatous inner layers thickened on one side of the seed and mesotestal spongy extensions at each end of the seed.
These represent cortical sclerenchymatous fibres or bundles that are characteristic of younger medullosalean stems and axes, and played a supporting role (Stewart and Delevoryas 1956; Basinger et al.
