Rafflesia hasseltii Suringar flower has been observed for the first time in Sambas District, West Kalimantan by the Flora Fauna Research Team during the Khatulistiwa Expedition organized by Special Forces Command of Indonesian Army in 2012. This finding is the first record of Rafflesia hasseltii in Kalimantan following the previous record in Sarawak. The flower has 5?6 perigone lobes. This paper presents the detail characteristic of the flower

Perilaku Tumbuh Kantong Semar (Nepenthes mirabilis Druce) di Habitat Alaminya, Taman Nasional Kutai, Kalimantan Timur
Get PDFNepenthes mirabilis has been widely known as an insectivorous plant species. A study on the growing behaviour of N. mirabilis in Teluk Kaba, Kutai National Park has been carried out. As many as approximately 840 individuals consisting of 307 rosettes and 533 mature plants were found. Variation in tendril’s position was observed in nine rosettes plants and in 22 mature plants. On the other hand, variations in leaf colour appeared in eight individuals. Variations in colour of pitcher and tendril were found in 17 individuals. The natural habitat of N. mirabilis was very specific, and it was also noted that 13 species were assosiated with this plant species. Further result will be discussed in this paper
MORFOLOGI DAN VIABILITAS POLEN PADA DUA SPESIES BELIMBING HUTAN (Averrhoa dolichocarpa dan A. leucopetala)
Get PDFWild starfruit Averrhoa dolichocarpa and A. leucopetala belong to Oxidaceae family. Both of these species are known as wild startfruit. Usage these species as a fruit or medicine are not discover yet. A number of flowers aborted during pre and at anthesis. As a result the flower failed to produce a fruit. The aims of the research were to study the pollen morphology and viability at a day before anthesis (H-1) and at anthesis (H0) stadia by the method of germination in the Brewbaker and Kwack (BK) and 10% sucrose media. The pollen shape of the wild starfruit (A. dolichocarpa and A. leucopetala) is globose with three aperture or tricolpate. Polen with smooth surfaces is A. leucopetala and polen with rogh surfaces is A. dolicocarpha, also included into the group of medium-type pollen. Preliminary study showed that the optimum incubation time of pollen germination test was 16 hours. BK medium showed a better result for germination test instead of 10% sucrose with viability 68.4% and 54.6%, respectively. Pollen viability of wild starfruit at H0 stadia (65.29%) was higher than pollen viability at H-1 stadia (57.68%) except on A. dolichocarpa that grow in the slopes on long filaments in both of BK and 10% sucrose media. Pollen viability of wild starfruit on long filaments were higher than on the short filaments i.e. 62.5% and 60.5%, respectively
KEBUN RAYA SRIWIJAYA: BENTENG KONSERVASI FLORA LAHAN GAMBUT SUMATERA
Get PDFEstablishment of The Sriwijaya Botanical Garden (Kebun Raya Sriwijaya or KRS) is one of an answer to address the declining rate of plant diversity in Sumatra. Occupied an area of 100 ha in Ogan Ilir Regency, conservation of Sumatran peatland flora was designated as the garden’s theme. The Sriwijaya Botanical Garden was launched on July 27, 2018 and to date has conserved 76 tribes, 191 genera, and 366 species. Supported with public facilities and infrastructures, it is expected that the Botanical Gardens will be ready to played its role as one of the leading plant conservation institution in Indonesia
