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 [...]
In this article we will discuss about the classification of dictyotaceae. Family Dictyotaceae: Plants are of moderate to large size, simple or branched, the divisions growing from apical cells or marginal rows of apical cells, forming fan-like foliaceous, strap- shaped branching thalli, usually composed of cortical and medullary layers of cells. Sexual and asexual generations are distinct, the plants of [...]
