Wood
Included phloem included in tangential bands of conjunctive tissue which form a reticulate pattern with the unlignified rays.
Vessels diffuse, solitary or in small multiples, round to oval, diameter 40-150 μm, 10-30 per mm², the variation mainly due to the unlignified vesselless zones.
Perforations simple. Intervascular pits alternate, round, 7-8 μm. Vessel-ray pits simple, oval to elongated, slightly irregular. Vessel member length 300-400 μm.
Ray-like zones of mainly unlignified parenchymatic cells linking the successive layers of conjunctive tissue.
Crystal sand present in radial and tangential conjunctive tissue.
Parenchyma scantily diffuse and as narrow vasicentric sheaths; fusiform cells and strands of 1-2 cells, 200-300 μm high.
Fibres thin-walled, walls 2-4 μm, lumina up to 25 μm wide. Pits minute, simple, numerous on both tangential and radial walls.
The only species occurring in the Guianas and represented in the Utrecht wood collection is the climbing lianaChamissoa altissima . The xylem body is divided in small parts by a network, formed by unlignified ray-like zones and wide tangential bands of unlignified conjunctive tissue ().
As far as known the wood is of no commercial value.
