Traditional Anti Malaria Plants Species of Balikpapan Botanic Garden, East Kalimantan-Indonesia

Numerous Kalimantan plants species were traditionaly utilized for its medicinal properties. Ex situ conservation of these species in Balikpapan Botanic Garden (BBG), one of the mostly recent launched botanic garden in Indonesia however, should be appreciated and encouraged to preserved the unique traditional plant-based medicine knowledge of Kalimatan people. An etnobotany literature study was conducted to documented traditional medicine plant species collected in BBG used by indigenous people of Kalimantan to treat malaria. This study found nine plant species collected in BBG namely Aleurites mollucanus (L.) Willd., Alstonia angustiloba Miq., Alstonia scholaris L. R. Br., Areca catechu L., Eurycoma longifolia Jack, Lansium parasiticum (Osbeck) K. C. Sahni & Bennet, Morinda citrifolia L., Peronema canescens Jack and Vitex pinnata L. were traditionally used to treat malaria. Further literature study showed that some of these species exhibits biological activity toward Plasmodium berghei and P. falciparum. Three species of this list were classified as rare medical plants in Indonesia. However, further study will still be needed to fully confirm anti malaria activity of these plant species and its potential to become new anti-malaria medicine.<div> </div>Keywords: Balikpapan Botanic Garden; ex situ conservation; Malaria; traditional medicine

One of the most exciting plant species is the Titan Arum, Amorphophallus titanum, which can truly be regarded as a flagship species for botanic gardens. Wild populations suffer from an increasing pressure on their natural habitat, but botanic gardens can play an important role in the ex-situ conservation of the species. The cultivation of A. titanum is not easy but it offers an irresistible challenge for any keen horticulturist. The University of Bonn Botanic Gardens (Germany) has more than seventy years of experience in the cultivation of this giant and the purpose of this paper is to help the botanic garden community to achieve success in the cultivation of this fascinating plant.

Citropsis articulata is a medicinal plant that is increasingly threatened by unsustainable methods of harvesting and habitat degradation. Owing to the fact that this plant species is highly utilized for herbal medicine and is currently restricted to a few forest reserves in Uganda, this has significant implications for ex situ conservation. Therefore, the aim of this study was to assess how physiographical factors influence the occurrence and distribution of C. articulata in the three forest reserves in Uganda, namely, Budongo, Mabira, and Kibale National Park. The study was carried out in 15 compartmental sites in each of the three forests. In each compartmental site, 4 plots of 60 m × 60 m were systematically established, and within each plot, 4 subplots each of size 20 m × 20 m were randomly setup. A total of 240 subplots were assessed for occurrence of Citropsis articulata in each forest. The results indicated a significant ( p < 0.05 ) variation in the density of C. articulata with the highest recorded in Kibale National Park. Citropsis articulata generally occurred at moderate altitudinal landscapes (overall elevation = 1200.0 ± 20.73 m) with soils that are moderately acidic (overall pH = 5.7 ± 0.10), low in salinity (overall salinity = 84.0 ± 3.84 mg/l), and moderate levels of macro- and micronutrients. Citropsis articulata was generally associated with plant communities dominated by canopy tree species of genera such as Chryosphyllum, Celtis, Markhamia, Cynometra, Lasiodiscus, Trilepisium, Funtumia, and Diospyros, thus suggesting that C. articulata is a shade-tolerant species. Establishing the ecological requirements of this plant species among other things informs the potential for ex situ production of this plant. This will not only provide alternative sources of plant harvest but also go a long way in relieving the current harvest pressures exerted on the conserved wild populations of this plant species.

In this study, we observed the flowering phenology, breeding system, pollination and seed germination of four species of Calligonum (C. calliphysa, C. rubicundum, C. densum and C. ebinuricum) in the Turpan Eremophytes Botanic Garden, China. Our results showed that the species had overlapping flowering phenologies and were pollinated by similar pollination agents. Their breeding systems were self-compatible, and with signs of outbreeding, but not of hybridization with each other; the main isolation mechanism was post-zygotic isolation and they also had high seed germination rates. Therefore, they are suited to ex situ conservation in the Turpan Eremophytes Botanic Garden, and can supply sufficient seeds for renewal populations and the conservation of germplasm resources. Furthermore, these results provide theoretical support for the construction of a national germplasm resource garden of Calligonum, and for the introduction to the garden of other eremophyteplants and their conservation.

Nepenthes Khasiana

Ex-situ conservation is an important key in the management of rare, endangered and threatened (RET) plant species and its effectiveness depends on several factors. Maintenance of viable germplasm and its subsequent propagation plays an important role in long term conservation of many RET species. Nepenthes khasiana is a rare and gravely threatened species in the wild due to over-collection and other threats. The species needs urgent in-situ and ex-situ conservation. Development of easy to propagate techniques would pave faster multiplication for its use of educational, medicinal and horticultural purpose. In the present paper, successful propagation technique of Nepenthes khasiana through seeds is demonstrated along with detailed information on precautions to be taken during the adoption of the techniques.

Background and Aims: There are approximately 3000 botanic gardens in the world. These institutions cultivate approximately six million plant species, representing around 100,000 taxa in cultivation. Botanic gardens make an important contribution to ex situ conservation with a high number of threatened plant species represented in their collections. To show how the Francisco Javier Clavijero Botanic Garden (JBC) contributes to the conservation of Mexican flora, we asked the following questions: 1) How is vascular plant diversity currently conserved in the JBC?, 2) How well is this garden performing with respect to the Global Strategy for Plant Conservation (GSPC) and the Mexican Strategy for Plant Conservation (MSPC)?, and 3) How has the garden’s scientific collection contributed to the creation of new knowledge (description of new plant species)?Methods: We used data from the JBC scientific living collection stored in BG-BASE. We gathered information on species names, endemism, and endangered status, according to national and international policies, and field data associated with each species. Key results: We found that 12% of the species in the JBC collection is under some risk category by international and Mexican laws. Plant families with the highest numbers of threatened species were Zamiaceae, Orchidaceae, Arecaceae, and Asparagaceae. We also found that Ostrya mexicana, Tapirira mexicana, Oreopanax capitatus, O. echinops, and O. xalapensis are highly threatened species representative of cloud forest currently in the collection. Conclusions: The conservation and scientific utility of the JBC collection is reflected in the exceptional accession data and the description of 24 new plant species. Having a significant number of threatened plant species in its ex situ collection, the JBC contributes to the implementation of the GSPC, particularly Target 8, as well as the implementation of the MSPC.

Botanical expeditions in Laos through a collaboration between Thailand (Queen Sirikit Botanic Garden) and Laos (Pha Tad Ke Botanic Garden) to document plant diversity and collect plants for ex situ conservation, led to the discovery of two species of Gesneriaceae previously believed to be endemic to Thailand: Damrongia trisepala (Barnett) D.J.Middleton & A.Weber and Didymocarpus formosus Nangngam & D.J.Middleton. Information on these species is provided.
