[1] Most published sources place it just inside Guyanese territory, very close to the border with Brazil, and around 17 kilometres (11 mi) east of Roraima-tepui.

[nb a] The village of Wayalayeng lies at the base of Maringma-tepui and it is from here that the mountain was explored in May–July 2004 by a botanical team of the Smithsonian Institution.

[3] The summit plateau has an area of roughly 170 hectares (420 acres) and is highly uneven, allowing water to collect in many deep, swamp-like pools.

[5] It is predominantly covered in low-growing "tepui meadow" vegetation, quaking peat bog, and some dwarf forests of Bonnetia roraimae, with few areas of exposed rock.

[1][5] The dominant plant families include Bonnetiaceae, Bromeliaceae, Clusiaceae, Orchidaceae, Rapateaceae, Sarraceniaceae, and Xyridaceae.
