Data Deficient (DD) within IUCN (2012) guidelines.
Guyana and Brazil (Amazonas).
Terrestrial in forests in montane areas.
Selaginella mazaruniensis is characterised by its erect stems, lateral microphylls with entire margins, dorsal microphylls each with outer base shortly auriculate, and an acute to acuminate apex. The megaspore surfaces are irregularly reticulate with spinulose micro-sculpture; the microspore surfaces are covered with irregularly spaced and sized verrucae, covered with dense spinules. Selaginella mazaruniensisresemblesS. amazonica Spring chiefly by its erect habit and dorsal microphylls, each with a short auricle in its outer base. It differs from S. amazonica by its lateral microphylls oblong-lanceolate (vs ovate-oblong to ovate-deltate) with acroscopic margin entire (vs serrate to denticulate); axillary microphylls oblong-lanceolate (vs ovate-deltate) and with entire (vs serrate to denticulate) margins.Selaginella mazaruniensis was described with no collection number indicated. Eighty-four years later, Alston et al. (1981) corrected the spelling of the epithet to “mazaruniensis”, indicating a specimen from NY as holotype and a specimen from BM as isotype (see McNeill et al. 2012, Art. 7.10; Prado et al. 2015). However, in NY, two specimens agree with the protologue. On neither of these sheets is there mention that they are part of the same collection (e.g. “1of2” and “2of2”), and it is not possible to determine if these were collected at the same time and place (see McNeill et al. 2012, Art. 8.1, 8.2, and 8.3). Additionally, the specimen from BM closely corre­sponds to a photograph taken from a NY specimen [NY 00029566], with a little fragment of a branch. Therefore, we clarify the status of these specimens by formally designating them as lectotype and isolectotype. As the NY specimens are well preserved, representative of the species, and in accordance with the protologue, we chose to typify S. mazaruniensis using the sheet NY 00029566. Fig. 3 & Fig. 4 A - C.
