Taxonomic remark From Cleal & Thomas, 2018: It is widely accepted (e.g. Crookall 1966) that they [Syringodendron] are stems of Sigillaria Brongniart where the outer layer of periderm including the leaf bases has been lost. Crookall (1966: 355) went as far as to synonymise Syringodendron and Sigillaria, but this would result in Sigillaria having to be suppressed in favour of Syringodendron; although Sigillaria is a conserved name (see below), Syringodendron is not one of the names it is specifically conserved against. Since few of the characters that are normally used to classify Sigillaria stems are preserved in the decorticated Syringodendron stems, combining the two fossil-genera would make little practical sense. Moreover, since the decorticated and non-decorticated stems arguably represent different states of preservation and yield different types of taxonomic information, there is no requirement for them to be synonymised.
