With the exception of palms, ferns, seaweed and some other species, no systematic inventory targeting plants have been made by 2008 in Masoala. However, there are is some botanical informationsinformation:
Botanical surveys within the peninsula conducted an extreme wealth of flora and uniqueness of vegetation in this region:
A study of the mangroves of Masoala counted seven tree species belonging to seven genera. The most common families are:
* Avicenniaceae, for example ''Avicennia marina'' ([[Grey mangrove]] or White mangrove)
* Meliaceae or Mahogany family, for example ''Carapa obovata''
* Sonneratiaceae, for example ''Sonneratia alba''<br><br>
Inventories of Pteridophyta (ferns) around Andranobe, Ambohitsitondroinan'Ambanizana and on Nosy Mangabe have demonstrated, that Masoala is the centre of fern diversity of northeastern Madagascar. 155 varieties distributed in 50 genera were collected, representing 27.3% of the ferns of Madagascar. 45 species were surveyed on Nosy Mangabe.<br><br>
In the marine plot of [[Tanjona]] nine species of marine phanerogams were inventoried, as well as the sea grass species ''Syringodium isoetifolium'', ''Thalassia hemprichii'' (turtle grass), ''Halophila ovalis'' (paddle weed) and ''Diplantera sp''.
99 species of seaweed were identified, including 40 species of red algae, 34 species of green algae and 25 species of brown algae.<br><br>
A botanical survey in different areas on the Masoala peninsula revealed, that Masoala is one of the richest regions in terms of palm trees in Madagascar. 50 species of palms were identified, out of which about a dozen can only be found on Masoala. Some of them areinclude:
* ''Marojejya darianii'' - [[Big-leaf palm]]
* ''Dypsis pachyramea''
* ''Voanioala gerardii'' - [[Forest coconut]]<br><br>
Almost half of the Malagasy species of Bignoniaceae grow on the Masoala peninsula. Four types of Bignoniaceae were inventoried, all of which are endemic to Madagascar. That They are:
* ''Rhodocolea''
* ''Ophicolea''
