Unlike Rafflesia, Rhizanthes is has not much been studied 51 much (Google Scholar search [June 7th, 2020]: “Rafflesia” 5090 results, “Rhizanthes” 254 results, 52 even “Sapria” is 855 results). Not much information covers the progress in propagation study Comment [Jaime5]: This could be a separate section if there is work on in vitro conservation, 53 (REF) and very limited studies covers the prospect of the plant, while the other studies have been seed propagation, cryoconservation, etc. Comment [AW6]: I’ve put in on later section 54 performed on Rafflesia and Sapria i.e. artificial pollination study which resulted in production of part 55 fruit (REFBänziger 2004).

Existing information on Rhizanthes mainly 68 focusses on morphology and taxonomy, and rarely on ecological aspects, eventhough the ecological 69 information are of importance for future conservation of the species. Ecological Studies on Rhizanthes 70 were limited to R. zippelii (Bazinger, 1995) and R. lowii (Susatya 2003). Study on ecology on Rhizanthes 71 was initially carried out by Bazinger (1995) who observed bud‟s growth and also estimated the life cycle 72 of R.zippelii. He estimated that the life history of R. zippelii reached up to 200 and 255 days after 73 emerging from its host plant. This figure were shorter than the life cycle of Rafflesia patma (Hidayati et 74 al. 2000) and R. arnoldii (Susatya 2020). Banzinger (1995) unfortanely did not provide the population 75 dynamics of the bud of R. zippelii which was important in term of conservation. Susatya (2003) futher 76 observed the mortality, growth, and the life history of R. lowii. He found that the population size of R. 77 lowii was 32 flower buds, which was higher than those of species of Rafflesia (Susatya 2020). Within 4 78 months observations, R. lowii suffered 25 % loss of its flower buds. All mortality occurred at very small 79 size diameter (0.50-0.94 cm). After running transition matrix analysis, he found that the intrinctive rate 80 of increase (alpha) of the species was 0.762. This indicated that the local population of R. loweii would 81 likely go extinct within 30 months (Susatya 2003). 82 83 In some region of Indonesia, Rhizanthes has been known for its ethnomedicinal properties, 84 especially by locals in Borneo island (Syaifuddin et al. 2018; Uluk et al. 2001).

    11TH FLORA MALESINA SYMPOSIUM, BRUNEI DARUSSALM, 30 JUNE 5 JULY 2019 1 Welcome message The Universiti Brunei Darussalam is honoured to host the 11th International Flora Malesiana Symposium. On behalf of the organizing committee it is my pleasure to welcome you to Brunei Darussalam. The Flora Malesiana Symposium is a fantastic opportunity to engage in discussion and sharing information and experience in the field of taxonomy, ecology and conservation. This is the first time that a Flora Malesiana Symposium is organized in Brunei Darissalam and in the entire island of Borneo. At the center of the Malesian archipelago the island of Borneo magnifies the megadiversity of this region with its richness in plant and animal species. Moreover, the symposium will be an opportunity to inspire and engage the young generation of taxonomists, ecologists and conservationists who are attending it. They will be able to interact with senior researchers and get inspired with new ideas and develop further collaboration. In a phase of Biodiversity crisis, it is pivotal the understanding of plant diversity their ecology in order to have a tangible and successful result in the conservation action. I would like to thank the Vice Chancellor of UBD for supporting the symposium. In the last 6 months the organizing committee has worked very hard for making the symposium possible, to them goes my special thanks. I would like to extend my thanks to all the delegates and the keynote speakers who will make this event a memorable symposium.

Sebagian besar publikasi terkini adalah pemberian nama species baru pada Rafflesia. Sejak tahun 2002, sepuluh spesies telah ditemukan di Filipina dibandingkan dengan tiga spesies di Indonesia. Karya terbaru filogenetik juga telah dieksplorasi (misalnya sejarah evolusi genus Rafflesia dan gigantisme, transfer horizontal gen dan hilangnya genom kloroplas) dan anatomi (misalnya endofit, pengembangan bunga); studi terbaru lainnya berfokus pada biokimia. Sayangnya, masih banyak informasi yang belum diketahui misalnya tentang siklus hidup, biologi dan hubungan ekologi pada Rafflesia. Kebanyakan informasi yang tersedia berasal dari hasil pengamatan. Misalnya penurunan populasi telah diketahui secara umum yang kadang kadang dikaitkan dengan kerusakan habitat atau gangguan alam tapi penyebab-penyebab yang lain tidak diketahui dengan pasti. Pertanyaan yang belum terjawab antara lain pada biologi reproduksi, struktur genetik populasi dan keragaman. Dengan adanya perubahan iklim secara global, kita amat membutuhkan studi populasi jangka panjang dalam kaitannya dengan parameter lingkungan untuk membantu konservasi Rafflesia. Keywords: Rafflesia, Indonesia, Biologi, konservation, review Abstract A literature review was conducted to summarize information, particularly recently published, on the biology of Rafflesia.

Flower development was divided into five distinct phases: (1) emergence, (2) post-emergence, (3) bract, (4) perigone, and (5) anthesis. Fruit development was monitored from flower senescence until fruiting and maturation. A total of 512 individual buds were monitored – discovered at different stages of bud development. Only nine buds were monitored from post-emergence until the perigone phase. A bloom rate of 19.73% and an overall mortality rate of 77.34% were recorded. Mortality was highest during the early phases (post-emergence and bract) and lowest at the perigone phase. R. consueloae exhibited nocturnal flowering; wherein anthesis usually begins at dusk, signaled by the detachment of the first lobe, and from there on, full bloom took 15 ± 5.85 h to complete. Flowering was at its highest during the coldest and driest months of the year – between December and April.

In this study, phylogenetic (parsimony and Bayesian inference) and Dispersal biogeographic (BioGeoBEARS) analyses of DNA sequence data (atp6 and matR genes, and nad1 B-C intron from Parasitic plants the mitochondrial genome, and the nuclear ribosomal internal transcribed spacer) were used to reconstruct the Divergence time phylogenetic relationships among 12 of the 13 known Philippine Rafflesia species and to determine the timing Malesia and pathways of their diversification. The results of these analyses confirm those of previous Rafflesia studies (which were largely focused on non-Philippine species) in finding pronounced biogeographic patterns. They suggest that dispersal between islands has been relatively uncommon, and indicate that the high island en- demism of Rafflesia is a result of poor inter-island dispersal abilities. The results further suggest that its ancestral range might have been in Borneo, and that its lineages and species evolved earlier and more gradually than previously assumed.

BOTANIC GARDEN PROFILE: BOGOR BOTANIC GARDENS Siti Roosita Ariati1 & Didik Widyatmoko2 ABSTRACT Bogor Botanic Gardens (BBG) was established in 1817 and is the oldest botanic garden in South East Asia. The garden has long been a centre for scientific research and has been the founding institution of a number of other research centres in Indonesia, particularly in the life sciences. The garden initially covered 47 ha but has expanded over the years and is now 87 ha. It has evolved over its 200-year history from a collection of economically valuable plants to the multi-faceted institute it is today, undertaking activities in plant conservation, research, education, ecotourism and environmental services. In recent years, it has strengthened its role in plant conservation through the establishment of 32 new botanic gardens across Indonesia. These new gardens are managed by local government and universities and supervised by BBG. In its bicentenary year, 2017, BBG organised a number of activities, programmes and celebrations and these are highlighted in this article. HISTORY After the East Indies were handed over to the Dutch Kingdom in 1815, King Willem I ordered C.T. Elout, A.A. Buskens and G.A.G.P. Baron van der Capellen to travel from Holland to Batavia (Jakarta) to take over the government from the British administration. Dr C.G.C. Reinwardt, a German botany and chemistry expert, was part of the official delegation (Went & Went, 1945; Rijnberg, 1992; Soegiarto, 1992).

    Dispersal of Rafflesia Patma Blume Endophyte in Grafted Host Plant (Tetrastigma Leucostaphylum (Dennst.) Alston)

    ADHITYO WICAKSONO & al. J. Plant Develop. 24(2017): 145-150 DISPERSAL OF RAFFLESIA PATMA BLUME ENDOPHYTE IN GRAFTED HOST PLANT (TETRASTIGMA LEUCOSTAPHYLUM (DENNST.) ALSTON) Adhityo WICAKSONO1, Jaime A. TEIXEIRA DA SILVA2, Sofi MURSIDAWATI3 Abstract: This study provides a hypothetical discussion about the growth of Rafflesia patma Blume (syn. R. horsfieldii R. Br. (1821); Rafflesiaceae), an endophytic parasite, within a grafted host, a woody vine (Tetrastigma leucostaphylum (Dennst.) Alston). Based on the observation of a 10-year old (2007 to 2017) R. patma – T. leucostaphylum graft, we hypothesize that R. patma moves away from its host rather than remaining in an anchored position from which it flowers, although flower knobs that emerge later may vary in range from the grafting point, i.e., flower knobs may develop close to or far away from the grafting point. Our provisional macroscopic observations point towards a gradual creeping motion of the endophyte towards new host tissues, flowering opportunistically when sufficient nutrients have been found. Much has yet to be discovered about the growth and flowering behavior of R. patma and about the dynamics of the R. patma – T. leucostaphylum interaction. Keywords: endophyte, parasitic plant, Rafflesiaceae, Tetrastigma, vine. Introduction Rafflesiaceae, which are the most minimalistic plants on the planet, having no leaves or roots, grow as an endophytic parasite inside a host, of the genus Tetrastigma.

Ir. Juanda 13, Bogor - 16003 E-mail: [email protected] Abstrak Rafflesia spp. (Rafflesiaceae) mempunyai nilai strategis jika ditinjau dari segi ilmiah maupun konservasi. Sampai sekarang tidak banyak usaha yang telah berhasil untuk mengkonservasi jenis-jenisnya secara ex situ dan usaha konservasinya terutama dilakukan secara in situ. Penelitian yang lebih rinci diperlukan untuk mengetahui hubungan antara Rafflesia dengan tumbuhan inangnya untuk meningkatkan pengelolaan dan konservasinya. Studi anatomi, kultur in vitro dan perkecambahan biji untuk mengkonservasinya telah dilakukan di Kebun Raya Bogor. Usaha mengkonservasi Rafflesia patma di lokasi konservsi ex situ telah membuahkan hasil. Namun demikian masih dijumpai tantangan untuk dapat menjaga kehadiran R. patma di lokasi konservasi ex situ karena diperlukan individu dalam jumlah banyak untuk memperoleh populasi yang lestari. Kata kunci: anatomi, konservasi ex situ, kultur in vitro, Rafflesia patma, studi lapangan Abstract Rafflesia spp. (Rafflesiaceae) have a strategic value from both scientific and conservation viewpoints. To date only very few attempts have succeeded in growing the species ex situ and the main protection measures have been by in situ conservation. More detailed studies are required to understand the relationships between Rafflesia spp. and their host plants in order to improve their management and conservation. Studies on the anatomy, in vitro culture and seed germination in connection with conservation have been conducted in the Bogor Botanic Gardens.

Wicaksono A, Mursidawati S. 2020. Short Communication: Lugol’s iodine test on Rafflesia patma-Tetrastigma leucostaphylum intersection tissue for preliminary starch visualization. Nusantara Bioscience 12: 91-96. As holoparasitic plant, Rafflesia has no recognizable plastid genome, but it has plastid-like organelle. Despite the fact that it obtains nutrients from host plant, it is unknown if Rafflesia stores primary metabolites, such as carbohydrates, from its host. A study was performed to visualize the starch in Rafflesia patma Blume proximal tissue which was intersected to its host root, Tetrastigma leucostaphylum (Dennst.) Alston, using modified Sachs’ test with Lugol’s iodine. The result revealed the absence of blackening in the R. patma tissue caused by starch reaction with the iodine, but occurred in the root cortical tissue of T. leucostaphylum. The absence of starch in R. patma tissue indicated that possibly the plastid-like organ has no similar function to amyloplast, and starch is not used for storage in the flower.
