Reinwardtia is a peer-reviewed scientific journal dedicated to advancing the understanding of plant science, with a particular emphasis on three core areas: plant taxonomy, plant ecology, and ethnobotany. The journal serves as a vital platform for disseminating research that explores the classification, identification, and relationships of plant species (taxonomy), the interactions between plants and their environments (ecology), and the traditional knowledge and cultural significance of plants (ethnobotany). Reinwardtia places a strong focus on the flora of Southeast Asia, a region known for its rich biodiversity and complex ecosystems. It extends its coverage to neighboring regions, including the tropical areas of Northern Australia, providing insights into the plant life of these biologically diverse areas. The journal seeks to contribute to the global scientific community by publishing original research articles, reviews, and notes that deepen the understanding of plant species in these regions and their ecological and cultural contexts.

Abstract

WANG, Q. W., BRAMLEY, G. L. C., ATKINS, H. J. & KARTONEGORO, A. 2022. Annotated checklist of Cyrtandra (Gesneriaceae) of Sumatra, Indonesia. Reinwardtia 21(2): 63‒80. — There are 53 species and three varieties of Sumatran Cyrtandra (Gesneriaceae) included in the checklist. Thirty-three lectotypes and four neotypes have been assigned, including for two excluded species. Two species are designated as incertae sedis due to a lack of type material or any associated specimens. A new name of C. jackii is proposed here to replace the illegitimate C. glabra Jack. Most of the species included in the checklist are endemic to Sumatra, with some species distributed in neighboring islands in Malesia. The next step for Cyrtandra in Sumatra is to carry out a full taxonomic revision to better understand distribution patterns and species limits and also to assign appropriate neotypes for those species still missing original material.

Abstract

The study aimed to assess the diversity status of mangroves and associates. Four transect lines were established perpendicular to the shoreline, ranging from 20 to 100 meters based on mangrove stand size. Along these transects, three 10 m × 10 m quadrat plots were set up to evaluate mangrove trees, and within each quadrat, a 2 m × 2 m regeneration plot was established. The study calculated the di-versity indices, such as relative frequency, relative density, and relative dominance to determine the species im-portance value. A total of four mangrove species and two associated plants were identified, representing three mangrove families and three genera, as well as three plant families and three genera for associated plants. The record-ed species included Avicennia marina, Nypa fruticans, Rhizophora mucronata, Sonneratia caseolaris, Acanthus ebrac-teatus, and Acrostichum speciosum. The overall diversity value of the mangroves and associated plants was 0.87, indi-cating relatively low species richness. The true mangroves, Rhizophora mucronata exhibited the highest values for relative density (68.07%), while Nypa fruticans is the highest in terms of relative dominance (42.20%). Both have the same highest value in relative frequency (32.43%). All in all, the highest species importance value for true mangroves is Rhizophora mucronata with 126.23%. In associated plants, highest value of relative density and relative frequency belongs to Acanthus ebracteatus with 58% and 60%, respectively. Subsequently, the highest species importance value for associated plants is 118% for Acanthus ebracteatus. The study concluded that the Mandangisiao Estuary in Jasaan, Misamis Oriental has a limited species diversity, contrary to the initial hypothesis. Furthermore, the mangrove forest in the estuary faces potential threats from garbage dumping, tree cutting, boat mooring, and human encroachment, despite all the recorded species having a Least Concern conservation status.

Abstract

Saninten (Castanopsis argentea) and tungurut (Castanopsis tungurrut) are plant species belonging to the family Fagaceae, native to the mountainous forest ecosystem within the Gunung Halimun-Salak National Park (GHSNP). These species are currently classified as endangered according to the IUCN Red List due to their significance in providing seeds for consumption and wood for construction materials. This research aims to examine the local community’s knowledge concerning the presence, scarcity, and underlying causes of the decline of both species in the buffer villages of GHSNP. In this study, we employed survey methods and semi-structured interviews conducted with various informants. The data collected were meticulously described and analyzed descriptively. The findings revealed that the local community, in general, holds knowledge about the scarcity of species primarily based on field observations rather than legal or conservation status. Currently, both species are challenging to locate in the buffer villages of the GHSNP. According to the local community’s knowledge, the causes of species scarcity can be categorized into internal and external factors. Internal factors include both species having a slow natural regeneration pattern, difficulties in germination, and vulnerability of seedlings to environmental conditions. Meanwhile, external factors encompass seed and timber exploitation, habitat loss, climate changes, limited knowledge, skills, and understanding of forest plants, and the current perception among locals that C. argentea and C. tungurrut offer limited economic benefits, leading to the gradual neglect of these species’ existence.

Abstract

A new species, Begonia tanggamusensis Girm. & M.Hughes (§ Platycentrum), is described from Gunung Tanggamus in southern Sumatra, where it is endemic. It grows on moss covered rocks and at the base of large trees in montane forests at an elevation of 1,700–2,000 m. A provisional conservation assessment places the species in the Near Threatened category.

Abstract

Miconia crenata is a widely spread species that occurs in multiple ecosystems. However, there is limited information on M. crenata invasion biology, ecology, and anatomy, particularly in the context of mountainous tropical forest and biodiversity management. Therefore, we examined elevation effects upon leaf anatomical structure of exotic invasive M. crenata at Mount Gede-Pangrango National Park (MGPNP). We sampled the leaves at four different elevations i.e., 715 m asl, 800 m asl, 900 m asl, and 1,000 m asl. Cross section leaf anatomy specimens of M. crenata were obtained by using paraffin method and stained with safranin and fast green. This study found that M. crenata leaf anatomy was correlated with elevation shown by changes in leaf tissue thickness and stomata size. Further study is needed of leaf anatomical variation of exotic invasive species along driven by soil properties and the variation across different plant taxa and growth forms. Such studies are important to determine adaptation capacity of invasiveness.

Abstract

We present a list of Athyrium species from Java and Bali based primarily on morphological examination. Some of disputed species were confirmed through molecular assess-ment. There are eight species of Athyrium in Java and two in Bali, none of them are endemic, but distribution of one species outside Java is uncertain. We provide the list with description, key to the species, and notes on taxonomy or distribution.

Abstract

A new Heptapleurum species from Sarawak, Borneo is described and illustrated as Heptapleurum connatum N.Ramnor, A.Puad & D.G.Frodin. It is an epiphyte or treelet recorded at various vegetation types such as near riverbank, limestone forests, remnant forests, hills and peat swamp forests from 10‒1,219 m asl. It is distinguished from H. truncatifructum by being slightly larger in size, having more second-order venations with narrow spacing between them, more flowers per umbel, and more stigmata on fused style. A distribution map of the species in Sarawak has also been constructed.
