Tambourissa cocottensis, commonly known as Bois Tambour[1] is a species of plant in the Monimiaceae family.

The only population (less than 50 individuals and decreasing) is endemic to the summit Montagne Cocotte, Mauritius (with an average annual precipitation of 5000 mm).

[2] T. cocottensis closely resembles T. tetragona in certain aspects such as cauliflory, leaf size, -margin, -texture, -shape or -venation.

They were in different stages of growth, suggesting that regeneration took place in previous years.

A poor pollination rate[1] further decreases the chances for this species surviving without help from humans.
