Monosiphonic, unbranched stems, up to 100 mm high, divided into internodes. Cauline apophyses with two axillary nematophores, each emerging through simple hole in perisarc (Fig. 15 B). Hydrocladia usually bifurcated, first hydrocladial internode giving rise to two secondary hydrocladia; however, a third-order hydrocladium is not uncommon (Fig. 15 A). First hydrocladial internode bifurcated, with two similar prongs (Fig. 15 A). Mesial inferior nematophore emerging from marked swelling at proximal third of internode (Fig. 15 C); with well-developed, claw-shaped nematotheca (Fig. 15 C–E). Hydrotheca low, about as high as wide, placed on distal half of internode. Abcauline wall straight; adcauline one mostly adnate (Fig. 15 C). Hydrothecal aperture circular (Fig. 15 D), roughly perpendicular to longitudinal axis of internode (Fig. 15 C); rim even. Gonothecae unknown. Remarks. Our material is undoubtedly conspecific with the material described as Oswaldella sp. 2 by Peña Cantero & Vervoort (2004). It is also morphologically very close to Oswaldella incognita (cf. Figs 8, 15), sharing many characteristics with this species (see also Peña Cantero & Vervoort 2004). The number of axillary nematophores, and the absence of 'mamelons', gives to the cauline apophyses of Oswaldella sp. a similar configuration to that found in O. incognita. Additionally, they share the presence of mesial inferior nematotheca, as well as the shape of nematothecae and hydrothecae. Peña Cantero & Vervoort (2004) indicated that Oswaldella sp. 2 has longer hydrocladial internodes and shorter hydrothecae and that they also differ in the fact that only secondary hydrocladia had been described for O. incognita.
