Centroaxoplastids have an axoplast at the centre of the cell, in a membrane-enclosed cavity within the nucleus, and radiating bundles of microtubules in a pin-wheel array (Fig. 6.13j), which is an extension of the cryptoaxoplastid pattern.

According to the distributional pattern of the axopodia and the location and form of their intracapsular organizing center, the axoplast, Hollande and Enjumet identified the following taxa: (1) the anaxoplastidies lacking a well-defined axoplast -- the radial axopodia arise in the central capsule cytoplasm from isolated ponts, sometimes near the papillae of the nuclear memberanel (2) the periaxoplastidies possessing a distinct axoplast occurring outside the nucleus either in a juxtanuclear position or in a concavity formed by the slight invagination of the nuclear envelope, or variously embedded within the fold-like center of a capiform nucleus; and (3) the centroaxoplastidies, exhibiting a centronuclear axoplast. In the latter group, the axoplast is surrounded by the nucleus.
