In this article we will discuss about the general features and phylogenetic relationships of phaeophyta. General Features of Phaeophyta: The Phaeophyta or brown algae, in general, are restricted to the sea—the seaweeds, with a few exceptional fresh-water forms (species of Heribaudiella, Sphacelaria, Lithoderma, Pseudobodanella and Pleurocladia lacustris, A. Br.). Usually the marine members are abundant in cold-waters. But warm-water brown [...]
In this article we will discuss about the classification of phaeophyta. Kylin (1933) divided Phaeophyta into three classes according to the type of life history. Further division of these classes into subclasses, and the arrangement of the orders, may best be understood from the key given below. This classification has received wide recognition for practical purposes although Papenfuss (1951) rejected [...]
In this article we will discuss about the classification of sargassum. Family Sargassaceae: Plants possess flat costate branches or transitional stages to cylindrical branches bearing numerous macroscopic spine-like projections, turbinate foliar organs, or costate leaves, usually with cryptostomata and buoyant air-bladders. Conceptacles are in ordinary branches or in special receptacular branchlet systems. Sexual reproduction is oogamous. Each oogonium produces a [...]
