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

Field exploration of the flora of the Mekongga Mountainous area of Southeast Sulawesi was conducted from 2009 to 2011. Herbarium specimens collected during this exploration and additional collections from Herbarium Bogoriense (BO) included 21 species in nine genera of the family Gesneriaceae. These comprise one species of Aeschynanthus, four species of Agalmyla, one species of Codonoboea, seven species of Cyrtandra, one species of Epithema, three species of Monophyllaea, two species of Rhynchoglossum, one species of Rhynchotechum and one species of Stauranthera. Twelve of these species are consider-ed endemic to Sulawesi while the rest are known to occur on neighbouring islands or are more widely distributed. Monophyllaea merrilliana, previously known only from the Philippine Islands and Borneo, is newly recorded for Sulawesi. A new species of Cyrtandra collected in the Mekongga area, C. widjajae, which resembles C. gorontaloensis from North Sulawesi but differs in having shorter pedicels and curved rather than straight fruits, is described.

Abstract

Codonoboea is the largest genus of Gesneriaceae in Peninsular Malaysia with 92 species. Nine sections, Boeopsis, Codonoboea, Didymanthus, Glossadenia, Heteroboea, Pectinati, Reptantes, Salicini and Venusti, have been erected based on morphological characters, such as habit, leaf arrangement and shape, type of inflorescence, number of flowers, corolla type and nectary type. Recent molecular phylogenetic study using ITS and trnL-F sequences show that only section Heteroboea is monophyletic. While the sections of Codonoboea can no longer be maintained as formal taxonomic taxa, as informal groupings they are useful in identification and in constructing keys.

Abstract

Two new species of Begonia, Begonia holosericeoides Ardi & D. C. Thomas and B. aketajawensis Ardi & D. C. Thomas, are described from Aketajawe Lolobata National Park, Halmahera, Indonesia. The two species belong to Begonia section Petermannia. Begonia holosericea, previously only tentatively assigned to a section, is here assigned to section Petermannia based on the examination of newly available material. Additionally, a revised description and an illustration are provided. A key to the Moluccan species of Begonia is presented.

Abstract

Amorphophallus discophorus Backer & Alderw. is one of the Javan endemic aroid species. This species is locally endemic to the slopes of Mount Wilis in Kediri Regency (East Java) at elevations between 600-1300 m. Poorly known species like A. discophorus could easily become extinct if not distinguished from other species, such as A. muelleri, that are used for commercial purposes. The conversion of natural forests for agriculture over the last decade has resulted in a loss of suitable habitat for this species. Several field trips undertaken to locate natural populations of this species have proved unsuccessful. Based on these field exercises, A. discophorus is regarded as presumed extinct in the wild.

Abstract

Local communities have their own means of maintaining their traditional know-ledge and sustaining the production system of natural resources by designating the resources as sacred. Without the state's influence, local people have their own strategies to conserve the environment and resources, in ways which are more effective than those enforced by the state. A study done through interview, participatory observation, and ethnographic methods revealed that local people recognized two models of natural resources conservation. The first model is the designation of forests as sacred site, aiming at maintaining the sustainability of ecosystem and the second model refers to adoption of species as a sacred entity to sustain production system. Dynamic processes are operating in the sacredness of both forest and species.

Abstract

DWIYANTI, F.G., KAMIYA, K. & HARADA, K. 2014. Phylogeographic structure of the commercially important tropical tree species Dryobalanops aromatica Gaertn. F. (Dipterocarpaceae) revealed by microsatellite markers. Reinwardtia 14(1): 43 – 51. ? Dryobalanops aromatica Gaertn. F. (Kapur) is an economically important timber species in Southeast Asia that can serve as a good model for studying the impact of the Pleistocene glaciations on the genetic diversity and distribution of species in tropical regions. Seven polymorphic microsatellite markers were analyzed in five natural populations of D. aromatica (N = 120 individuals): Gunung Panti in Malay Peninsula, Lingga Island in Lingga Archipelago, Lambir Hills National Park, Limbang and Similajau National Park in Borneo. The level of gene diversity (HE) for the five populations was relatively high with a range from 0.571 (Similajau) to 0.729 (Gunung Panti). The high genetic diversity in the present study could be attributed to the larger refugia population sizes of D. aromatica than that of other species. The population genetic structure revealed two distinct groups: the Malay Peninsula-Lingga Archipelago and Borneo. This pattern suggests that populations in each geographical area might be the consequence of post-glacial expansion from one or two refugia, but that gene flow between different glacial refugia was fairly restricted.

Abstract

NISHIDA, S. & VAN DER WERFF, H. Do cuticle characters support the recognition of Alseodaphne, Nothaphoebe and Dehaasia as distinct genera? Reinwardtia 14(1): 53 – 66. ? The Asian members of the Persea group are divided among the genera Alseodaphne, Apollonias, Dehaasia, Machilus, Nothaphoebe and Phoebe. A recent phylogenetic analysis has shown that Machilus and Phoebe are supported as monophyletic genera but evidence that the closely related genera Alseodaphne, Dehaasia and Nothaphoebe are monophyletic or not was equivocal. In this study we analyzed cuticle characters of 95 collections belonging to the Asian members except for Apollonias. We anticipated two possible outcomes. If the genera were not monophyletic, we expected that the groups based on cuticle characters would consist of species belonging to different genera. If the genera were monophyletic, we expected that the groups based on cuticle characters would consist of species belonging to the same genus. We found 16 groups based on cuticles. Of these, 12 consisted of species of a single genus (one group included a single species and thus a single genus). The four mixed groups included mostly species of one genus with 1 or 2 species of a different genus. Our results support the recognition of Alseodaphne, Dehaasia, Machilus, Nothaphoebe and Phoebe as distinct genera.

Abstract

LATIFF, N. A., SUKRI, R. S., & METALI, F. Nepenthes diversity and abundance in five habitats in Brunei Darussalam. Reinwardtia 14(1): 67 – 71. -- The genus Nepenthes is known to be diverse in Bornean forests and has been recorded in Brunei Darussalam in various forest types. We aim to investigate variation in Nepenthes species richness and abundance at five forest types throughout Brunei Darussalam: open secondary, heath, peat swamp, white sand and mixed dipterocarp forests. A total of thirty-nine 5 x 5 m2 plots were set up in these forest types. Within each plot, Nepenthes species abundance was quantified, with Nepenthes voucher specimens collected and identified to determine species richness. No significant differences were detected either for Nepenthes species richness or abundance between the five forest types, despite records of Nepenthes in Brunei showing preferences for particular habitat types. We suggest that average species richness and abundance remained constant regardless of forest types in this study, but that these results would likely change if sampling intensity is increased in future studies.
