Abstract Background The picturesque limestone karsts across the Sino-Vietnamese border are renowned biodiversity hotspot, distinguished for extremely high endemism of calciphilous plants restricted to caves and cave-like microhabitats that have functioned as biological refugia on otherwise harsh habitats. To understand evolutionary mechanisms underlying splendid flora, dated phylogeny is reconstructed Asian Begonia , a species-rich genus substrates represented by no less than 60 species in...
Abstract The polyphyletic genus Chirita is remodelled after an extensive molecular phylogenetic study of species assigned to it and other associated genera. Most sect. the monotypic Hemiboeopsis are amalgamated with Henckelia , resulting in a very differently circumscribed synonymisation . remaining accommodated revived Damrongia Liebigia recognised as Microchirita Gibbosaccus is, together Chiritopsis Wentsaiboea included originally now enormously expanded Primulina. necessary combinations...
Abstract The pantropical genus Begonia is the sixth–largest of flowering plants, including 1870 species. sections are used frequently as analogues to genera in other families but, despite their taxonomic utility, few current have been examined light molecular phylogenetic analyses. We present herein largest, most representative phylogeny published date and a subsequent provisional sectional classification genus. utilised three plastid markers for 574 species 809 accessions Hillebrandia an...
Musa L. (Musaceae) is currently separated into five sections (Musa, Rhodochlamys, Callimusa, Australimusa and Ingentimusa) based on chromosome numbers morphological characters. However, the validation of this classification system questioned due to common occurrence hybridizations across not accommodating anomalous species. This study employed amplified fragment length polymorphism (AFLP) in a phenetic examination relationships among four (material sect. Ingentimusa was available) evaluate...
Taxonomic and systematic studies of the woody bamboos are traditionally based on floral morphology, which can cause problems in identification due to lack of, or infrequent, flowering. Limited have been conducted using molecular techniques overcome this problem. In study, we used amplified fragment length polymorphisms (AFLPs) conduct a study four genera ( Bambusa , Dendrocalamus Gigantochloa Thyrsostachys ) subtribe Bambusinae. AFLP analysis eight primer combinations was carried out 15...
Study of the unique leaf anatomy and chloroplast structure in shade-adapted plants will aid our understanding how use light efficiently low environments. Unusual chloroplasts terms size thylakoid membrane stacking have been described previously several deep-shade plants. In this study, a single giant cup-shaped chloroplast, termed bizonoplast, was found abaxial epidermal cells dorsal microphylls adaxial ventral spike moss Selaginella erythropus. Bizonoplasts are dimorphic ultrastructure:...
Premise Unique among vascular plants, some species of Selaginella have single giant chloroplasts in their epidermal or upper mesophyll cells (monoplastidy, M), varying structure between species. Structural variants include several forms bizonoplast with unique dimorphic ultrastructure. Better understanding these structural variants, prevalence, environmental correlates and phylogenetic association, has the potential to shed new light on chloroplast biology unavailable from any other plant...
Abstract Mangifera odorata Griff. (Anacardiaceae), was suggested to be a hybrid between M. indica L. and foetida Lour. due morphological intermediacy. Results from this study show that produced unique amplified fragment length polymorphism (AFLP) profiles. did not produce any bands. All the samples additively inherit bands specific , which strongly origin. Three major clusters were in phenogram. of segregated distinctly. closer than indicating backcrossing with might have taken place. AFLP...
Besides Begonia conipila, 13 new species (Begonia apiensis, B. benaratensis, conniegeriae, divergens, lucychongiana, magentifolia, melinauensis, ramosissima, rhodoneura, umbratica, vulgare, yiii and xiphophylloides) a putative natural hybrid between conipila lucychongiana are described from the Melinau limestone. All these endemic in limestone 10 restricted to habitats. The includes highest hills Malaysia with Gunung Api (1710 m) Benarat (1615 m), which above 800 m covered by montane forest....
Batu Caves hill is typical of karst hills in Peninsular Malaysia due to its small size and high biodiversity. It harbours 366 vascular plant species that represent about 25% the Peninsula’s limestone flora. Five are endemic 23 threatened species. This biodiversity result many microhabitats, each with their own assemblages Threats especially severe as area surrounded by urbanisation encroaches foot cliffs, vulnerable fire, habitat disturbance and, formerly, quarrying. Assigning a Conservation...
The vascular plant flora of Batu Caves, a tower karst limestone formation, includes 269 species; 51 species (19%) are Peninsular Malaysian endemics and 80 (30%) calciphiles which 56 (21%) obligate 26 endemic to Malaysia. Four taxa Caves itself. That harbours sizeable fraction (21.4%) Malaysia’s underlines the need for detailed checklists each every hill enable adequate planning conservation programmes support biodiversity. Because botanical collecting began in 1890s, is important as type...
Three new species, Gymnostachyum kanthanense Kiew (Acanthaceae), Meiogyne kanthanensis Ummul-Nazrah & J.P.C. Tan (Annonaceae) and Vatica Saw (Dipterocarpaceae), from Gunung Kanthan, Perak, are described illustrated. All three Critically Endangered CR B2ab (iii, iv), D1 being known very small, restricted populations at the type locality. Kanthan is currently quarried for cement on a large scale, which if it continues threatened all species with extinction.
Following the revision of Peninsular Malaysian Begonia, a project that involved extensive fieldwork, we now have sufficient data to assess their conservation status. Out 54 taxa, 48 are endemic Malaysia. No fewer than 30 taxa known from five localities; 24 Critically Endangered (CR), 3 (EN) while 4 Vulnerable (VU). One taxon is Extinct (EX), 22 remaining Near Threatened (NT), Least Concern (LC) and Data Deficient (DD). We discuss how assessment was carried out implications for long-term...
