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

Traditionally, morphological parameters have been used for several taxonomic and ecological identifications. The morphological characteristics alone would be difficult to distinguish the evidence for species identification. Hence, a study of leaf anatomy was conducted to compare the structural characteristics which focused on the epidermal cells, stomata, and trichomes by using a Compound Microscope and Scanning Electron Microscope (SEM). Four selected species of Hoya from various localities within western of Sarawak were studied: H. caudata, H. coronaria, H. omlorii, and H. verticillata. The results showed stomatal types of Hoya species have stephanocytic stomata, except for two species which have slightly significant differences: H. coronaria has anomocytic stomata and H. omlorii has paracytic stomata. Meanwhile, in terms of the stomatal presence, all species possessed hypostomatic stomata, only H. verticillata has amphistomatic stomata which stomata presence on both sides of the adaxial and abaxial surfaces. Highest stomatal density was recorded in H. omlorii whereas the lowest were recorded in H. coronaria. Stomatal index were calculated and H. caudata has the highest with 12.80% and H. coronaria has the lowest value which is 6.28%. All four species were completely absence of trichomes except for H. coronaria which has simple unicellular non-glandular trichomes. The result indicates that the anatomical characteristics provide additional information and could be a great assist in the distinction within Hoya species.

Abstract

This study aimed to identify and analyze ethnobotanical data on phytonym, utilization, and cultural value of plants mentioned in an Old Sundanese text. Since plants are mentioned with their vernacular names, identification was based on an exhaustive bibliographical search of the respective scientific name. A comprehensive investigation led to the identification of a total of 85 Old Sundanese phytonyms, which represented vernacular names for 79 distinct plant species. Furthermore, by considering the number of identified species from the plant-related glosses, 93 species belonging to 57 genera and 44 plant families were registered. Among these plant families, Arecaceae (12 species), Poaceae (nine species), and Fabaceae (six species) exhibited the highest number of identified species. In addition to the phytonyms, 36 phytotoponyms, which utilize vernacular phytonyms to designate settlements, hermitages, ports, mountains, and rivers were identified. It was worth noting that the majority of the plants associated with these phytotoponyms were indigenous. Meanwhile, only 13 species were traced back to the pre-Columbian exchange period during the Austronesian migration and the Indianization-Sinicization era in IndoMalayan history. The result showed that the predominantly mentioned utilization included beverage production, textile manufacturing, vessel craftsmanship, betel quid preparation, perfume creation, and incense production. Among the identified species, Areca catechu emerges as the most frequently mentioned in the text, along with Graptophyllum pictum and Cordyline fruticosa, which were also considered as possessing profound spiritual value due to association with heavenly realms. Furthermore, the text highlighted that the production of plant-based fragrance products, also referenced in the celestial domain, held significant prominence in global trade during the 15th century

Abstract

Acanthaceae family has been used traditionally for medicinal purposes, especially amongst the native communities in Peninsular Malaysia. Nowadays, many taxonomists have difficulties in the identification of the Acanthaceae species due to its morphological similarities and when there is an incomplete part of plants obtained from the field sampling. But until now, there is no comprehensive study that has been documented especially on the Acanthaceae family, specifically for A. gangetica subsp. micrantha and R. nasutus. To avoid incorrect species identification, a systematic study that involved the leaf anatomy and micromorphology parts is being used for the identification and classification of plants in the Acanthaceae. Therefore, the main objective of this present study is to identify the leaf anatomical and micromorphological characteristics that can be used in plant identification and for supportive data in plant classification. The leaf anatomical and micromorphological studies that are conducted on species studied involve several procedures such as cross-section using a sliding microtome, and observation under a light microscope and scanning electron microscope. The anatomical and micromorphological characteristics observed that have been used to identify each species studied include patterns of petiole and midrib vascular bundles, leaf margin, leaf lamina, presence of cuticular striae, and the presence of trichomes. The results of this study showed that the cystolith cells can be found only in midrib of A. gangetica subsp. micrantha while it also recorded in petiole, midrib, and the leaf lamina of R. nasutus. Observation under the light microscope revealed nine types of trichomes in R. nasutus meanwhile seven trichomes were recorded in A. gangetica subsp. micrantha. Other than that, the present of cuticular striae only recorded at the abaxial epidermis of A. gangetica subsp. micrantha. In conclusion, results showed that anatomical and micromorphological characteristics have taxonomic significance that can be used in the identification and classification, especially at the species level

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.
