Figs. 71-79. P. indicum Kashyap. 71. Female plant showing multiple sporophytes (sp) developing within each pseudoperianth (p); scale bar = 2.5 mm. 72. Branched male plant showing the ( rows of the antheridia (an) that develop the entire length of the thallus; scale bar = 1.5 mm. 73. SEM micrograph of a female plant that has furcated at the apex, although this cannot be observed on the dorsal surface, with each plant having one pseudoperianth (p) with multiple sporophytes (sp); scale bar = 260 μm. 74. SEM micrograph of the same male plant as in figure 72; antheridium (an); scale bar = 280 μm. 75.

SEM micrograph of the thallus wing showing a highly erose margin; scale bar = 100 μm. 77. SEM micrograph of the thallus wing showing the vertical elongation of cells just below the margin to the base of the wing; scale bar = 100 μm. 78. SEM micrograph of a lamella showing the distinct margin; scale bar = 100 μm. 79. Thallus showing the distinct tangentially elongated marginal cells; scale bar = 100 μm.
