Description

Plant terrestrial (Fig. 1 A) mainly lithophytic, diffuse mat-forming. Stems widely creeping, dichotomous, flat, articulated, glabrous. Rhizophores on the upper side of the stems along the entire length of the stem, 1-3 mm in diameter (Fig. 1 B). Leaves dimorphic, delicate; lateral leaves almost perpendicular to the stem, green, well-spaced, lanceolate, 2-3 × 0.3-1.1 mm, base rounded, margin slightly transparent to green, toothed, apex pointed (Fig. 1 C); median leaves lanceolate to linear-lanceolate, 2-2.5 × 0.2-0.7 mm, apex acuminate, base cordate and unequal, margins finely toothed. Strobili, solitary, with only one basal megasporangium, situated on short side branches, 2-25 mm; sporophylls toothed, strongly tapering towards the apex, base glabrous, marge denticulate, apex acuminate; megasporophylls larger than microsporophylls, in groups of four, lanceolate-elliptical to falcate-lanceolate; microsporophylls lanceolate to narrowly ovate-lanceolate.

Distribution

Distribution in Senegal: Kédougou Region (Fig. 2 B).

Ecology

Selaginella kraussiana is found predominantly as a lithophyte at altitudes between 133 and 391 m a. s. l., on both sides of the Dindefélo Falls cliff, but it is more confined on the south side at almost all levels of the cliff at 100 m, 90 m, 80 m, 60 m, 50 m, 20 m and 10 m high and on the north side at 50 m and 30 m. The souhern part of the cliff is humid and very sunny, with few species of trees, unlike the northern part which is less humid and very sunny. On the Dindefélo cliff, S. kraussiana was found each time under plant cover in association with pteridophyte species such as Aleutopteris farinosa (Forssk.) Fée , Blotiella currorii (Hook.) R. M. Tryon , Dicranopteris linearis (Burm. f.) Underw. and Selaginella versicolor Spring , but also with byophytes and spermatophytes such as Dombeya quinqueseta (Delie) Excell , Mitragyna inermis (Willd.) K. Schum. and Raphia sudanica A. Chev. It forms a green carpet on the rock. It is also found on land on the banks of a river on the Bembou-Massa axis.
