Description
Summary:FIGURES 48–52. Orthoseira johansenii R.L.Lowe & Kociolek sp. nov. Scanning Electron Micrographs. Fig. 48. Internal view of an entire valve showing three carinoportulae. Fig. 49. Internal view of a valve linked to a second valve. Note the rather shallow mantle and hyaline area around the two carinportulae. Fig. 50. Detail of a broken valve edge showing the structure of the areolar canal closed by a velum. Fig. 51. Detail of a few areola in cross-section. Fig. 52. Detail of the carinoportulae. Note the absence of small slits between the carinoportulae. Scale bar represents 10 µm in Figs 48 & 49, 2 µm in Figs 50 & 52 and 1 µm in Fig. 51. Published as part of Lowe, Rex L., Kociolek, J.
