FIGURE 3. Structure of the stem in Sciurella indivisa Allman, 1883. A. Internode (only the "frontal" cladia are shown). B–D. Three stem apophyses supporting cladia, with (B) or without (C, D) proximal nematothecate internode (N.B.: Only the "frontal" pair of axillar nematothecae is depicted in B–D). E. Detail of the axil of a stem apophysis in apical view, showing mamelon and lateral pairs of nematothecae. From samples: MHNG-INVE-0137405 (A–C, E), MNHN H.L. 1373 (D – type material). Scale bars: B–E = 200 µm; A = 500 µm.
