The image is a photograph of a plaque on a stone wall. The plaque is rectangular in shape and has a white background with black text. The text reads "Allee Pierre Boiteau (RAPIERRE) 1911-1980 Botaniste" which translates to "Director of the Parc Botanique and Zoologique de Tambazza et des Parcs and Jardins de Tananarive (1934-1938) and 1940-1947). Below the text, there is a description of the botanique, which is a collection of plants and animals from around the world. 

The plaque is located on the side of a brick wall and is attached to the wall with two screws. It appears to be a historical marker or plaque.
