“…3). There are also at least four reported hybrids in the world (Kathiresan 1995;Parani et al 1997;Duke et al 1998a) and there are likely to be more. In the IWP, there are four reported species [R. mucronata, R. stylosa, R. apiculata and R. mangle (= R. samoensis)] and three hybrids (R. lamarckii, R. selala and R. annamalai).…”

“…Its distribution reflects the overlapping distributions of its parents (Duke and Bunt 1979). Recent reports of additional Rhizophora hybrids (e.g., R. selala and R. annamalai) might also be viewed in this way (consider Tomlinson 1978;Parani et al 1997). This is important when assessing distributional records, since systematic field and herbarium determinations and descriptions of hybrid forms have been inconsistent and systematic distributional records are generally lacking in most places, except for Australasia.…”

Mangroves are often described as a group of plants with common features and common origins based mostly on their broad distributional patterns, together with an erroneous view of comparable abilities in longdistance dispersal. However, whilst mangroves have common needs to adapt to rigorous environmental constraints associated with regular seawater inundation, individual taxa have developed different strategies and characteristics. Since mangroves are a genetically diverse group of mostly flowering plants, they may also have evolved at quite different geological periods, dispersed at different rates from different locations and developed different adaptive strategies. Current distributions of individual taxa show numerous instances of unusual extant distribution which demonstrate finite dispersal limitations, especially across open water. Our preliminary assessment of broad distribution and discontinuities reveals important patterns. Discontinuities, in the absence of current dispersal barriers, may be explained by persistent past barriers. As we learn more about discontinuities, we are beginning to appreciate their immense implications and what they might tell us about past geological conditions and how these might have influenced the distribution and evolution of mangroves. In this article, we describe emerging patterns in genetic relationships and distributions based on both current knowledge and preliminary results of our studies of molecular and morphometric characteristics of Rhizophora species in the Indo West Pacific region.

“…As such, they are usually located wherever the ranges of their putative parents overlap. Records of hybrid distributions confirmed by the author show R. × lamarckii (the best known of all hybrid intermediates of the genus) to be widespread in the western Pacific extending to New Caledonia, while R. × annamalayana (Parani et al 1997) has been found only in India and Sri Lanka along the western limits of R. apiculata (Fig. 1).…”

The determination of hybrid status of R. × selala (= R. samoensis × R. stylosa) is based solely on the intermediate morphological and reproductive characters (Tomlinson 1978).…”

A recent survey of mangroves in New Caledonia located 7 taxa of the genus Rhizophora -with 6 coexisting in one estuary. This is arguably the greatest concentration of co-occurring Rhizophora taxa anywhere. Two are well-known mangrove species of the Indo West Pacific, R. stylosa and R. apiculata, and another, R. samoensis resembles the widespread Atlantic East Pacific species, R. mangle. The other four are hybrid intermediates, R. × lamarckii (= R. stylosa × R. apiculata), R. × selala (= R. stylosa × R. samoensis), and two previously undescribed combinations, R. × tomlinsonii (R. apiculata × R. samoensis) and R. samoensis var. neocaledonica (= R. samoen sis × R. × selala). The new entities are unknown elsewhere. While R. × tomlinsonii is considered endemic to New Caledonia, R. samoensis var. neocaledonica may occur elsewhere based on the co-distribution of putative parental taxa. All seven Rhizophora are described with new observations on their morphology and ecology, distribution maps, plus a revised key for the region.

“…Molecular markers like random amplified polymorphic DNA (RAPD) and amplified fragment length polymorphism are extensively used to quantify the inter-specific, intra-specific and inter-generic variability in different plant groups and crop varieties (Chalmers et al, 1994;Lin et al, 1996;Garcia Mas et al, 2000;Sharma et al, 2000;Mukharjee et al, 2003;Begum et al, 2013). Parani et al (1997) identified the parentage of Rhizophora hybrid, by establishing its maternal status using molecular markers such as RAPD and RFLP. Jian et al (2004) analyzed the variation in inter simple sequence repeats (ISSR) in mangrove and non-mangrove populations of Heritiera littoralis.…”

The genetic diversity of Xylocarpus a tree mangrove species was assessed. Three species viz., X. granatum, X. moluccensis and X. mekongensis were collected from different localities of the states of Tamil Nadu and Andhra Pradesh in India. These three species showed high degrees of phenotypic variation in the vegetative parts such as leaf, bark and root. To assess the variations at the molecular level within the three species of Xylocarpus a RAPD technique was used. A total of 283 DNA fragments were generated by 25 random primers, with an average of 11.32 easily detectable fragments per primer. A higher similarity was observed between X. mekongensis and X. moluccensis, whereas X. granatum and X. mekongensis showed lower similarity. X. granatum and X. mekongensis had a variation of more than 79 %. On the other hand, X. mekongensis and X. moluccensis seem to be closely related with 35% variation. These variations may be due to its genotypic variation, isolated distribution and adaptation to dissimilar edaphic and environmental factors. All the three species of Xylocarpus are related at various degrees. These results will be helpful in future to assess the existing interspecific genetic polymorphism in Xylocarpus species and to design strategy for their conservation.
