Northern Kerala of southern India is characterized by widely spread lateritic plateaus which provide an extremely harsh physical environment for life leading to the development of specialized plant communities with a large number of endemic and habitat specific species. Madayippara, a midland lateritic plateau located in the Kannur District of northern Kerala is an icon of rich floristic diversity and endemism. The plateau forms a number of microhabitats due to the difference in geographic terrain and soil cover, thus forming a complex of habitats with diverse forms of plants, mainly ephemeral herbs. Out of the 636 flowering plant taxa recorded from the microhabitats of the plateau, within a limited area of 3.65km2, 160 (c. 25%) are endemics. Most of the endemic species occur in specialized microhabitats. The plateau is the type locality of 11 taxa. Lateritic plateaus of southern India, which are associated with characteristic and rich biodiversity, are now under varied types of anthropogenic threats such as large scale mining for bricks and clay, and they need urgent attention for conservation of the biodiversity.

“…In Bromeliaceae, centres of palaeoendemism occur in the Guayana Shield -the site of putative origin of the family -whereas centres of neoendemism are restricted to the Brazilian Shield, where Bromelioideae subsequently radiated (Givnish et al, 2011). Eriocaulaceae mirror this pattern (Andrino et al, 2023), with the added area of super-endemism in India, where nearly 20% of the family occurs in the Western Ghats region alone (Sunil et al, 2015).…”

● Poales are one of the most species-rich, ecologically and economically important orders of plants and often characterise open habitats, enabled by unique suites of traits. We test the hypotheses that Poales species are assembled into distinct phyloregions, with centres of high phylogenetic diversity and endemism clustered in tropical regions, and that cosmopolitan families show parallel transitions into open and closed habitats at different times. ● We sampled 42% of Poales species and obtained taxonomic and biogeographic data from the World Checklist of Vascular Plants database, which was combined with open/closed habitat data scored by taxonomic experts. A dated supertree of Poales was constructed. We integrated spatial phylogenetics with regionalization analyses, historical biogeography, ancestral state estimations, and models of contingent evolution. ● Diversification in Poales and assembly of open and closed habitats result from dynamic evolutionary processes that vary across lineages, time, space, and traits, most prominently in tropical and southern latitudes. Our results reveal parallel and recurrent patterns of habitat and trait transitions in the species-rich families Poaceae and Cyperaceae, yet other smaller families display unique evolutionary trajectories. ● The Poales have achieved global dominance via parallel evolution in open habitats, with notable, spatially and phylogenetically restricted divergences into strictly closed habitats.

“…Additionally, Prasad and Singh (2002) recorded 115 species from India. In recent decades, nine new species viz., Fimbristylis matthewii Murugesan et al (2010), F. velliangiriensis Murugesan et al (2010), F. clarkei Kumar et al (2013), F. pokkudaniana Sunil et al (2016), F. tuckeri Viji et al (2016), F. pandeyana Mujaffar, Wad. Khan and A.P.Tiwari (2017), F. murthyi Yarrayya and Kumar (2018), F. agasthyamalaensis Viji and Preetha (2018) and Fimbristylis sunilii Sanilkumar and Nithya (2021) have also been described.…”

A new species, Fimbristylis pachmarhiensis (Cyperaceae), is described and illustrated from Pachmarhi Biosphere Reserve of Hoshangabad district, Madhya Pradesh, India. This new species bears resemblance to its closest morphological relatives, F. aestivalis and F. griffithii, but differs from both by a combination of characters, primarily including its slender culm, exceptionally lax inflorescence, cylindrical spikelets, triquetrous structure, and the presence of fine hairs covering the entire length of the style. Additionally, the achenes of this species exhibit sparse tuberculation and have a depressed apex. A detailed description, phenology, distribution, IUCN conservation status, a comparative analysis contrasting F. pachmarhiensis with its closely related species, relevant taxonomic notes and colour photographs are provided.
