Figure 3 in Species of Antarctoscyphus Peña Cantero, García Carrascosa and Vervoort, 1997 (Cnidaria: Hydrozoa: Symplectoscyphidae) collected by US Antarctic expeditions: biogeographic implications

Figure 3. Antarctoscyphus asymmetricus Peña Cantero, García Carrascosa and Vervoort, 1997: (a) fragment of a lateral branch showing hydrothecal arrangement; (b) distal part of cauline internode showing axillary hydrotheca and origin of paired branches; (c) hydrocladial branching (note hydrotheca outside axil of branches); (d, e) hydrothecae (note extreme development of one abcauline cusp); (f, g) gonothecae; (h) detail of gonothecal aperture. Scale bars: 1 mm (a), 250 µm (b, f), 200 µm (g), 150 µm (d, e), 50 µm (h).
