Description
Plant lithophytic (Fig. 3 A). Rhizophores located in the lower half of the stem up to 2 cm long, glabrous, filiform, greenish-white making a right angle with the stem then curved downwards (Fig. 3 B). Stem decumbent at the base, slightly ascending distally, up to 50 mm long, staminate, greenish, pale; branches glabrous, diverging by approximately 60 °, bipinnate with oval outline. Leaves heteromorphic; lateral leaves spaced, unequal, about 2 mm long by 1.20 mm wide, apiculate, the upper half semi-ovate-oblong, cordate and surrounding the stem at the base, ciliate on the adaxial half, loosely serried towards the top (Fig. 3 C); lower half semi-oblong, tightly rounded at the base. Median leaves distant on the main stem, imbricated on the branches, very small, ciliolate, toothed outline, oval in shape, acuminate, aristate at about 2 / 3 of the length of the blade. Strobile at the top of the main stem and branches approximately 2.5-3 mm long by 1-2.5 mm wide. Dimorphic sporophylls: dorsal sporophylls, oblong green, acuminate, shortly awned, irregularly serrulate with occasionally ciliate-toothed keel; ventral sporophylls hyaline, deltoid, acuminate, awned, ciliate; megaspores ochre yellow, finely rough on the distal surface (Fig. 3 D).
Distribution
Distribution in Senegal: Three Regions: Kédougou, Tambacounda and Ziguinchor (Fig. 4 B).
Distribution in Africa: Cameroon, Ivory Coast, Gabon, Ghana, Guinea, Liberia, Nigeria, Sierra Leone and Sudan (GBIF. org 2022 b) (Fig. 4 A).
Ecology
Selaginella subcordata is found as a lithophyte at altitudes between 116 and 483 m a. s. l., on either side of the Dindefélo Falls cliff, at 100 m, 60 m, 50 m and 1 m on the south side and 90 m, 40 m on the north side. The southern part of the cliff is humid and not very sunny, with a few species of trees, unlike the northern part which is less humid and very sunny. On the Dindefélo cliff, S. subcordata as well as 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 was also found on the track going down the Dimboli cliff, but also on rocks not far from the Sédou stream bridge in Ebarack. In Ziguinchor, it was found on a small damp humid area, covered with bushes, along a path. In Tambacounda, the habitat of historical specimens from Niokolo-Koba Park, has not been mentioned.
Notes
Selaginella subcordata was first collected in April 1951 by Berhaut J (BR 0000020401276), then on 25 October 1990 by Vanden Berghen C. (BR 0000015471284) and recently by Mingou et al. 2019, 2020 (See Senegalese materials examined above) and is reported for the first time for Senegal.
