Studies on the Structure and Reproduction of Populations of Cystoseira indica (Fucales, Phaeophyta) from Pakistan

S. Afaq-Husain
Abstract
External morphology, anatomy and reproductive structures were studied in the plants of different populations from 700 km of coastline (out of 885 km) of Pakistan. All these populations are treated taxonomically as Cystoseira indica (Thivy et Doshi) Mairh instead of Stokeyia indica Thivy et Doshi, due to the presence of a primary holdfast and production of rhizomatous branches secondarily from the stipe; the dioecious nature of the areal axes; the presence of non-axillary receptacles and the development of vesicles in the ultimate vegetative branchlets. Variations in the Pakistani populations from those of India in height of plants, plasticity of apex to flattening, size and position of vesicles and size of receptacles are discussed.
