Axodine

The name points to a character that is deemed to be synapomorphic for the group: that is the microtubular arrays that extend from the surface of the nucleus. Many flagellated forms have a single emergent flagellum, that lacks the root structure found in related chrysophytes.

The traditional botanical treatment of the group follows Order Dictyochales The most notable group is the silicoflagellates, marine plankton that form siliceous skeletons and are well known as fossils. Order Pedinellales Most other axodines form a group variously called the pedinellids. Order Rhizochromulinales In addition to the silicoflagellates and actinodines, the marine amoeboid Rhizochromulina marina is included here based on the structure of its zoospores. It is considered closer to the latter group than the former. == References ==
