Abstract: The investigation on the vegetation and Pollen flora of the Ranikot fort area was undertaken during 2011-2015. Ranikot Fort Area is a historical heritage of Sindh, Pakistan. This fort is certainly considered to be possibly one of the most significant forts around the globe. So far there has been no publication on vegetation of this important historic site. Eightynine plant species belonging to sixtynine genera and thritytwo families are identified which includes Monocot. Dicots. and Pteridophytes. This contribution provides information on plant biodiversity of Ranikot fort area, a natural heritage of Sindh, Pakistan. We acknowledge that the planet earth is a plentiful and differing area filled with fascinating societies as well as people, from whom you will find a whole lot to discover. Area under investigation is full of diversity of life, categorized as lower plants, Monocots. Dicots. and variety of fossil woods. This study will help to develop the flora of Ranikot. The Floristic Diversity of Ranikot fort area was carried out to document the Range of Diversity present among Dicot. and Monocot. vegetation of this important historic site area. It’s been observed that amongst all Monocot. families Poaceae was dominant. The vegetation of the calcareous rocks is greatly influenced by the rainfall. Most of the summer annuals appear after the first rainfall and within a month the bare rocks are covered by the green carpet of Aristida and other plants. Five Monocot. families have been reported. In Dicot. families Astraceae was found dominant among all families. Seasonal variation has also noticed among Monocot. and Dicot. families. During rainy season Poaceae has been found dominant among all Monocot. and Dicot. families, whereas during summer Astraceae was dominating over Poaceae. There were very few number of trees present in Ranikot fort area, their number can be count on finger tips. Among all tree species Acacia nilotica (Linn.) delile. and Commiphora wightii (Arn) Bhandari. were found threatened. Only few trees of Acacia and Commiphora wightii are left due to frequent use of local people. V Palynology of most of the plants has been done with the help of Scanning Electronic Microscope (SEM) at the University of Karachi. SEM of pollen of some species could not be done due to non-availability of materials. Every possible effort was made to cover the maximum number of species. The pollen morphology has been conducted to study the selective pollen flora of the region. Different types of pollen is identified. Patterns were very common. Considerable pollen characters have been observed, especially grain shape, size, aperture type, Aperture size, exine ornamentation. Grains are mostly spheroidal, spheroidal-Prolate, Prolate, sub-Prolate, oblate spheroidal in shape. Grains are mostly colpate, colporate with some porate grains. Both kinds of apertures have been observed. Number, size and position of apertures varies from species to species. Extremely different Exine ornamentation has been observed, ranging from echinate, striate, regulate, scabrate, foveolate, granulates, psilate, punctate, reticulate. This study provide the information about the presence of eightynine species in Ranikot fort area, which can contribute to the indigenous utilities of natural plant resources of Ranikot fort area to the researchers, touriusts and scholars from different fields. It has also been observed that the shape and exine ornamentation of pollen, are significant pollen attributes which can be used for the identification of species.
