FIGURE 7. A to G: Dentitheca dendritica (Nutting, 1900)—fragment of poly- (A) and monosiphonic (B) parts of stem; stem apophysis and origin of cladium (C); hydrothecae (D, E); hydrothecal rim in lateral (upper figure) and frontal (lower figure) views (F); lateral nematotheca with deep emargination on adaxial side, and three mesial nematothecae showing variation in shape of upper chamber (G). H and I: Plumularia margaretta (Nutting, 1900)—stem internode with cladium and hydrotheca (H); gonothecae (G). J to M: Plumularia setacea (Linnaeus, 1758)—portion of stem (J) and cladium (K); variability among ahydrothecate cladial internodes (L); gonotheca (M).
