Â Batang Gadis National Park (BGNP) located in Bukit Barisan Mountains, Sumatera Utara. A Mandailing tribeÂ who lives around the BGNP, has the unique local knowledge, such as processing young stem of rattan (Calamus manan) into pakkat (traditional food) and use rimbang (Solanum torvum) to neutralize toxins. These local knowledge could be lost because it only inherited orally from generation to generation. This study was aimed to reveal ethnobotany knowledge of Mandailing Tribe. The study was conducted in November 2015 in four villages around the BGNP, Sibanggor Jae, Hutabaringin Julu, Pastap Jae, and Botung Villages. Data were collected by interviewing informants in each village as well as the field survey through two approaches, emic and etic. A total of 262 plant species is used by Mandailing Tribe for subsistence and commercial needs. The highest utilization is for foodÂ (106 species), followed by traditional medicines (81 species), firewood (29 species), building materials (35 species), and animal feed (25 species). People also used plant for household appliances, agricultural equipment, art materials, ropes and wrap, and pest control materials. Eme/rice (Oryza sativa) have the highest Index of Cultural Significance (ICS) values. The existence of this species is maintained for its local wisdom. Thus, involvement ofÂ localÂ community will give great contribution to manage and conserve the BGNP area.Â

Pandam Gadang has tropical forests which become the habitat of Rafflesia (Rafflesia arnoldii) which grows as a parasite of Tetrastigma (Vitaceae). Study on R. arnoldii is needed since its population continuously decrease as a result of habitat destruction of its host. The aim of the study was to determine habitat conditions, vegetation structure, and characteristic of the host species of Rafflesia; to identify environmental factors, and determine the Rafflesia habitat suitability in Pandam Gadang Koto Tinggi Village, West Sumatra. Analysis of vegetation in the habitat where Rafflesia grows using a circular plot. The number of individuals Rafflesia found was recorded and completed with observations of its morphology. Micro-climate measurements were carried out together with data collection in the field. Flower morphological analysis was descriptively presented. Environmental parameters were-processed with Canoco software 4.56 using Canonical Correspondence Analysis. Habitat suitability was analyzed using Maximum Entropy. The 17 Rafflesia individuals found on Pandam Gadang were R. arnoldii, known as "Cendawan Biriang", living parasitically on Tetrastigma leucostaphylum. The results of analysis of vegetation in the Rafflesia habitat showed that there were 250 individual plants consisting of 42 species and 21 genera. Seedlings most dominant was Lauraceae, belt were dominated by Moraceae, Meliaceae, and Euphorbiaceae. Trees were dominated by Euphorbiaceae, Moraceae, and Meliaceae. Existence and survival of R. arnoldii depended on soil pH 7-7.8, environmental humidity 83-91.8 % and distance from the nearest river 3-27.8 m.

Pulasan (Nephelium ramboutan-ake (Labill.) Leenh) fruit is highly similar to rambutan rapiah (Nephelium lappaceum) fruit with ovate shape, sweet and sour fresh taste, but it has a thick rind. The diversity of pulasan is little informed including in Bogor. The objective of this study was to analyze the genetic diversity of pulasan from Bogor revealed by microsatellite marker. The DNA of 63 individuals from 10 populations of pulasan were extracted using CTAB method and amplified using two primer sets, LMLY6 (GA)9(CA)2(GA)4 dan LMLY12 (CT)11. DNA amplification product was visualized and arranged in a matrix of binary data then analyzed the value of the number of different alleles (Na), the number of effective alleles (Ne), Shannon information index (I), heterozygosity (He), and the percentage of polymorphism (PLP). The results of the analysis showed the highest genetic diversity was found in North Bogor (He=0.313). The genetic diversity within a population (61%) was higher than that among populations (39%). A dendrogram was constructed using the Unweighted Pair Group Method with arithmetic Mean (UPGMA). The similarity index ranged from 52 to 100% that means there are close relationships among individuals. Cluster analyses grouped some individuals originated from different locations in the same group. The levels of heterozygosity within a population was determined by the history of each individual in a population.

Adiantum lunulatum Burm. f. has been widely used in aesthetic needs and medical fields. Detail information about the life cycle of A. lunulatum is still unknown, particularly about its gametophyte generation. Present work aimed to study and compare the growth and development of the gametophytes of A. lunulatum from dry and humid areas. Research method consists of two stages: (1) Spores were collected from two locations, Pasuruan and Bogor and (2) Spores were planted and observed the growth and development of gametophyte. The result showed that natural habitat of the plant in various dry and humid areas, affecting the rate of growth and development rates of A. lunulatum gametophyte. The gametophyte from the dry area showed faster rate of growth and development than that of humid areas. The spores collected from dry area need 9 weeks for germination, growth, and development while the spores of humid area took 22 weeks.

The morphology of sporophyte, the type of reproduction, and cytology of Pteris had been reported, while the gametophyte morphology of Pteris in Java island has not been studied yet. The objective of this study was to describe the gametophyte morphology and development of P. biaurita, P. ensiformis,Â P.exelsa, P.longipinnula, P. tripartita, andÂ Â P. vittata in Java island. Spores were obtained from fertile leaves of Pteris plants originated from several locations in Java island. The number of spores per sporangium were counted from fresh fertile leaves with mature sporangia. As much as 0.002 g spores was sown in transparent box with sterile medium contain of vermiculite, spaghnum moss, and perlite with ratio 2:2:1. The gametophyte development of each species was observed under a microscope every 7 days. The spores of P. ensiformis were germinated faster, 10 days after sowing, while the spores of P.longipinnula were germinated slower, 18 days after sowing.Â The pattern of spore germination is Vittaria-type. The development of gametophyte is Ceratopteris-type in common, but in a few cases is the Adiantum-type. The gametophyte development of observed Pteris spesies are varied in six characters including the number of filament cell, germinated time, formation time of notch and gametangia, margin shape, and development type.

Spathoglottis plicata is a ground orchid that displays large variation in flower features. In spite of large variation on morphological characters, its anatomical and cytological characters are not well known. This paper described the leaf anatomical and chromosomal features of S. plicata. Leaf anatomy was observed from both transverse and paradermal sections of leaves. Chromosome numbers were observed from root tip cells. Epidermis of all S. plicata variants comprised of two cell shapes, the rectangle cells located above veins, while the polygonal one located in between veins. Stomatal type was brachitetracyclic, which were only found on lower epidermis. Leaf transversal section comprised of one layer of upper and lower epidermis, spongy mesophyll, and vascular tissue. The number of leaf hair varied depended on the original habitat and altitute. All variants of S. plicata had same chromosome number (2n=40).
