manoxylic
Sparse, with much pith and cortex, and having wide parenchymatous rays.
The significance of pycnoxylic versus manoxylic organisation of wood is still not well understood. Pycnoxylic wood is a primitive feature of progymnosperms with regard to manoxylic wood with wide and high rays.
Where it comes from
From Ancient Greek μανός (manós, “sparse”) + xylic, equivalent to mano- + xylic.
