FIGURE 10. Nematothecae of Sibogella erecta Billard, 1911 (A–I), S. flabellata sp. nov. (A′–I′), and S. spissa sp. nov. (A′′–I′′): from the stem apophyses supporting the cladia-bearing branches (A, A′, A′′), from the stem internodes (B, B′, B′′), axillar borne on the cladial apophyses of cladia-bearing branches (C, C′, C′′), unpaired thecae of the cladial apophyses of cladia-bearing branches (D, D′, D′′), from the internodes of cladia-bearing branches (E, E′, E′′), from the first cladial internode (F, F′, F′′), laterals associated to the hydrothecae (G, G′, G′′) and mesial (H), of the whip-like, distal appendages (I, I′, I′′).
