Blades extend peripherally from a continuous marginal meristem (Figure 3E, H–J), 45.7±5.1 µm thick, bilayered, cells of the epidermal and hypodermal layers 11.3±2.4 µm and 34.3±3.9 µm thick respectively. Epidermal cells rectilinear in surface (Figure 2H–K), cross-sectional (Figure 2N). Hypodermal cells cuboidal in cross-section (Figure 2N), rectilinear or in long section (Figure 2O), 32.3±3.2 µm in width by 59.7±3.9 µm in length. Juvenile hairs (Figure 2L, M) clustered. Oogonia, antheridia and sporangia unknown. Differing from N. imbricata by (1) the distinctive radial development of surface blades from points of origin and (2) the 4% difference in rbc L nucleotide sequences [PC0063019 (IRD 11128) and IRD 11129].</p><p>Ethymology</p><p>The epithet “yhaga ” comes from the word “Yhag”, which is the general name for brown algae in Bel language that is spoken by the villages surrounding Madang Lagoon and in other areas in Madang province.</p><p>Holotype</p><p>PC0063019 (IRD11128), leg.
