If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|D. H. Erwin et al. 2011||Arboreomorphs are a clade of fronds with bifoliate petaloids consisting of parallel primary branches which diverge from the central stalk at acute to right angles (45°–90°) and end at an outer margin. The branches are all joined together and possibly attached to a dorsal sheet. Primary branches are composed of teardrop- shaped secondary branches which are at right angle to the primary branches. The central stalk is large and prominent.|
