Notes.

Maracanthus chlamydatus is recognised as the only species in the genus with conspicuously lenticellate greyish stems and sessile spikes with marginally greyish floral bracts. Several types and paratypes have handwritten notes with the binomial “ Maracanthus strobiloideus Kuijt ”. However, this name was never validated nor effectively published.
