Doryopteris majestosa is a beautiful fern species from South America. The specific epithet - ‘majestosa’ refers to the majestic appearance of its large fronds.
In the past it was mistakenly identified as D. nobilis (T Moore) C. Chr. which also has noble features, such as being large in size and having similar division of the fronds.
However, D. majestosa can be distinguished by the presence of proliferous buds at the base of the lamina, which are absent in D. nobilis.
D. majestosa was described as a separate species by Dr Jovita Cislinski Yesilyurt, the Museum’s Botany Collections Manager, in 2007.

"This species is quite easy to misidentify under another name. This is 1 of the few species of the genus Doryopteris that can be spotted quite easily (and collected) and therefore it would be important to have them represented in the herbaria collections properly identified. Moreover, it can be a species that is not listed in the local or regional floras, although I do not believe that it is under threat, but they can be key species to identify ‘less impacted habitats’."

With two sets of chromosomes in each cell.
Frond that produces spores.
