Scinaia complanata (Collins) Cotton var. intermedia(Rhodophyta) was newly recollected from Abu-Qir locality along Alexandria seashore. The alga showed multiaxial construction, dichotomously branched thallus, attached to the rocks by multicellular rhizoids. The female gametophyte carried unilocular, uninucleate carpogonia produced on carpogonial branches. Constitutive urea-amidolyase was the enzyme responsible for ¹⁴C-urea-degradation in this alga; ¹⁴C-urea transported via passive mechanism. This alga was characterized by its high protein, amino acids, fatty acids, Ash and Mg contents. It was also characterized by absence of mercury, low Ni, Mn, Zn and Co contents; as well as low iodine value.
