Abstract

Anatomical structures may vary among the species of Nepenthes. Therefore, the anatomical characters apparently could be used for supporting the morphological characters in identifying species. This study aimed to seek a valuable anatomical character for identifying and defining five species of Nepenthes occur in Bangka Belitung Islands. Samples of leaves, pitchers and its lids of Nepenthes gracilis, Nepenthes mirabilis, Nepenthes ampullaria, Nepenthes rafflesiana, and Nepenthes reinwardtiana were collected and prepared for paradermal and transverse section of microscope slides. The results showed that the anatomical characters of the leaves, pitchers and lids from these five species of Nepenthes could be used for differentiating five species Nepenthes observed. The absence of nectary gland at the abaxial of pitcher lids of N. gracilis and N. ampullaria separate them from others species. The leaf epidermis of these two species have different cell wall. The length of lunate cells at the inner surface of upper half pitchers are comparable for identifying the pitchers of N. mirabilis from those of N. reinwardtiana.  The presence of crystal at the parenchymal tissue of pitcher differentiate N. rafflesiana from the four others.  In this research, the identification key for Nepenthes from Bangka Belitung Islands based on the anatomical character was presented.

Abstract

Dischidia is an epiphytic plant, it is used as herbal medicine and has economic value. In addition, Dischidia also has an ecological function. Moreover, some species of Dischidia are endemic in a particular region. Various forest types occur in Bangka Island serves as natural habitat for this epiphytic plant. This research aimed to record the diversity and abundance of Dischidia and analyze those environmental factors which affect its abundance. The research was conducted in August – September 2016 at Bangka Island. Three plots of 20 × 20 m² were placed with a minimum interval of 50 m in the habitat where Dischidia are found. The species diversity and abundance of Dischidia as well as abiotic factors such as temperature, humidity, light intensity, wind speed, and altitude were recorded in these plots. The vegetation structure was analyzed based on index of diversity, index of dominancy and index of evenness. Data on the environmental condition and abundance of Dischidia were then analyzed using Canonical Correspondence Analysis (CCA) method with Canoco 4.5 software. Five species of Dischidia were found in Bangka Island that are Dischidia bengalensis, Dischidia imbricate, Dischidia nummularia, Dischidia rafflesiana, and Dischidia hirsute. Dischidia is found in 14 species of host plants. D. imbricate (23 individual plants) occurred in the heath forest at Pejem showed the highest abundance. Epiphytic fern plants, the Asplenium nidus (27 individual plants), was the dominant epiphytes found in the host tree of Dischidia The CCA showed that light intensity, temperature and humidity influenced the abundance of Dischidia.

Abstract

DEWI, A. P., ARIYANTI N. S. & WALUJO, E. B. 2016. Diversity of plants used for plaited crafts by the Dayak Iban-Désa in Kabupaten Sintang, Kalimantan Barat. Reinwardtia 15(2): 67 – 79. — Many plants are used for making plaited crafts such as basketry and woven mats by the Dayak Iban-Désa, a sub-tribe of the Dayak in Kalimantan Barat, Indonesia. The Dayak Iban-Désa gather the craft materials mostly from the plants in the forest. However, the habitats of these plants are being threatened by deforestation. The diversity of plants used for crafts is here documented. This study recorded the scientific names of plant species used for the craft plaiting, and observed abundance of plants used for craft. Information about the plants used were gathered using non-structural interview and focus group discussion (FGD) with the informants and participants. The abundance of plaited plants was observed in 46 plots of 10 × 10 m2 plots by participative ecological method. Nineteen plants species were used as plaited material, belonging to four families: Arecaceae, Poaceae, Pandanaceae and Zingiberaceae. Two species of rattan (Calamus sp. and Plectocomiopsis wrayi Becc.) have the highest Index Cultural Significance (ICS) value. Those species were considered as the most valuable plant materials because of the quality of fiber, intensity on harvesting, and the resulting quality of plaited craft products. However, the demand for high quality products is not always supported by the availability of plant materials in the forest. Therefore, the cultural significance of plants (the ICS values) and their availability should be considered when determining the conservation strategy for each of these species.

Abstract

Mangosteen (Garcinia mangostana) cultivation has problems in terms of fruit quality and rooting system. This problem is solved by Mekarsari Fruit Garden by developing the technology of double rootstock seedling that is by combining two mangosteen seedling into one plant through the pasting process. Characterization of the collection of mangosteen plants and its species of relatives (Garcinia spp.) is needed to seek superior characters used for the technology of double rootstock seedlings, cultivar development, and management and preservation of mangosteen germplasm. This study aims to record and compare morphological and anatomical characters of mangosteen and its relatives collected in Taman Buah Mekarsari. The study was carried out by collecting the sample and characterizing the morphological structure using mangosteen descriptor, observing the leaf paradermal anatomy, and collecting secondary data. Observation on the morphological characteristics of mangostana (G. mangostana) and its relatives (G. celebica, G. dulcis, G. forbesii, and G. malaccensis) showed variations on the fruit characters, such as the shape is spherical, ovate or spherical flattened apex and base; the rind color is bright yellow, deep red, and bright red; the flavor is sour, sour sweet, or sweet. The anatomical character of the mangosteen leaf and four species of its relatives show the paracytic stomata on the abaxial surface only except on the leaf of G. forbersii, which is found on the abaxial and adaxial sustance, the epidermal cells are square to rectangular, the wall is straight or slighty winding except that of G. forbesii which is sharply winding or zig-zag

Abstract

Research on epiphytic bryophytes has been conducted in two different sites located in Universitas Indonesia (UI). Those sites were urban forest and vegetation on main street margin of the campus. This study was carried out to compare diversity of the bryophyte at both sites. Twelve plots of 25 x 25 m2 were establish at the forest, while nine of 50 m line transect were made at the street margin. Five trees of each plot or line transect were sampled. Eight sub plots of 15 x 15 cm2 were placed on each trunk base (0--200 cm) of the tree sampels. The results obtained 23 species of epiphytic bryophytes, 21 species occured in the forest and 14 species were found at street margin. The similarity of bryophyte community between the forest and street margin were high (Sorenson similarity index = 0.73). Octoblepharum albidum was the dominant species at the forest, while Calymperes tenerum was dominant at the street margin. The diversity of epiphyte bryophyte at both sites were categorized low based on Shannon Wiener index (H’< 2), however they were not different significantly.

Abstract

Recent more intensive explorations and collections of hornworts in Mt. Slamet indicated that six species can be recognized, namely Anthoceros punctatus, Folioceros fuciformis, Phaeoceros carolinianus, P. exiguus, Dendroceros difficilis, and Megaceros flagellaris. Since originally only one species D. difficilis was recorded from this area, this means that five species represent new records for the area, whereas P. exiguus is not only a new record for Java, but it is also a new record for Malesia.

Abstract- A few people know Indigofera, but as a admirer of batik and tenun, these plant gives hope for the preservation of batik. Indigofera has a variety of benefits , but more commonly known as blue dye in batik and tenun. The problems of restore the glory of Indigofera from Indonesia who had experienced the triumph can be divided into three principal. There are the increasing scarcity of Indigofera plant, the lack of willingness of the community batik for the cultivation, the process of indigo dyeing longer and complicated, and the results of staining with the natural color is not uniform. The problem by the business presence of more efficient synthetic dyes,  the price of synthetic dyes is cheaper. While research on Indigofera dye is still limited and stagnate, this is a problem should be a concern Botanist .  Keywords: Indigofera, batik, tenun, natural dye
