Plants in the genus Rafflesia (Rafflesiaceae) bear the largest flowers in the world. Almost all members of this holoparasitic plant family have limited ranges and are rare or threatened. This genus is therefore important from a scientific and conservation perspective. An ex situ conservation collection of a population of Rafflesia patma Blume has been monitored at Bogor Botanic Garden (BBG) since 2004, the first time that this has ever been done. Studies have been made, including propagation trials on both seed and vegetative material at BBG. Of all the propagation methods tested, grafting on to the host plant Tetrastigma scariosum (Blume) Planch proved to be the most successful for growing R. patma, resulting in blooming having occurred seven times since 2010. Grafting is the quickest way to propagate Rafflesia in cultivation. This cultivation process provides a new hope for the conservation of this endangered and charismatic genus. This paper describes the methods trialled including both unsuccessful techniques as well as those which resulted in blooming events.

The Acharya Jagadish Chandra Bose Indian Botanic Garden (AJCBIBG) previously known as Indian Botanic Garden, Howrah, is a historic old garden. This botanic garden has a special position among all the botanic gardens that the world having. In earlier time this garden witnessed as the centre of plant introduction. Till then AJCBIBG served as a centre for ex-situ conservation of many RET species collected from different parts of the globe. The rich and diverse floristic wealth of this garden makes it unique and very special. AJCBIBG is a living repository of 1377 species of plants (excluding herbs). The garden abode a rich herbaceous flora due to its congenial climate. However, records on the herbaceous plants dwelling in AJCBIBG are very scanty. Taking this into account the present study aimed at enlisting the herbaceous flora of the garden. A checklist of plants belonging to various families has been provided in this communication.

Cibodas Botanic Garden, as ex situ conservation areas, preserves living materials ofthe wet mountains flora. Recently, bioprospecting study for dye in this areas has not yetbeen done. Therefor, the aim of this study was to inventory of natural dye in Cibodas BotanicGarden. Sampel were collected by exploration methods. Parts of plants, kinds of color andits chemical compound were recorded based on observation, interview with nurseries andliterature study. A total of 122 species that belongs to 57 families were potentially source asnatural dye, 23 of them has been traditionally used as natural dye in the various places inIndonesia. The plant family of Fabaceae, Rosaceae, Symplocaceae, and Myrtaceae are themost families that used as a source of dye. The color can be produce are ranging from red,purple, yellow, black, brown, green, blue, and orange. The plant organs used as a source ofdye are roots, stems, leaves, flowers, and fruit. Begonia semperflorens,Berberis nepaulensis,B.fortunei, Symplocosspp., Liquidambar formosana, andDiospyros kaki were potentially fornatural dye, as reported from other countries.

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.

One challenge of ex situ conservation is developing propagation methods that promote a high rate of survival and genetic diversity. Developing successful propagation methods is especially important for rare species to prevent their extinction. Clasping warea, Warea amplexifolia (Nutt.) Nutt. (Brassicaceae), and scrub lupine, Lupinus aridorum McFarlin ex Beckner (Fabaceae), are two rare species endemic to imperiled Florida sandhill and scrub habitats, respectively. We tested whether the collection site of seeds, seed stratification temperature, and several propagation methods influenced germination and initial survival of W. amplexifolia and L. aridorum. The collection site of seeds and type of pot influenced percent germination of W. amplexifolia, whereas soaking seeds in water and stratification temperature did not. The site where seeds were collected did not influence germination of L. aridorum and treating seedlings with salicylic acid, nitrogen, or salicylic acid and nitrogen sometimes reduced, but did not increase, initial survival of seedlings. Overall, our results will inform additional experiments on ex situ conservation and may be applicable to other herbs endemic to Florida.

Sambas Botanical Garden is an ex-situ conservation area, in its management there is the term Vak, which is a small management area with care and supervision that is more focused on the inside plants, Bellucia pentamera in the management of Vak is very limited and cut down, but actually Bellucia pentamera is forest plant which has the criteria of providing fruit almost all year long and is widely used by most wildlife. The study aims to record species of aves and diurnal mammals that use Bellucia pentamera as a source of feed for wild animals in the Sambas Botanical Gardens. The research was carried out in the management area and secondary forest, each represented by three growing places, namely hills, foothills and riparians. The study was conducted in July-August with a survey method by observing direct observation at the point of tangkalak guava stands with repetitions three times. The results showed that seven types of aves were found, namely Chloropsis sonnerati, Dicaeum trigonostigma, Dicaeum trochileum, Pycnonotus goiavie, Chloropsis cochinchinensis, Zosterops palpebrosus, and Arachnothera crassirostris, There are four types of mammals found, namely Macaca fascicularis, Sundasciurus lowii, Callosciurus prevostii, and Callosciurus orestes.Keywords: Aves, Bellucia pentamera, Feed, Mammals

Amborella trichopoda Baill., the most ancestral angiosperm, has been successfully cultivated in the Botanic Gardens of the University of Bonn in Germany (BG Bonn) for more than a decade. The distribution of this plant – limited to the South Pacific island of New Caledonia – and its cultivation has so far only been achieved in a few botanic gardens. This paper provides details about the cultivation and propagation of Amborella, and information on its cultivation in botanic gardens around the world. The authors propose that the collections of this plant in botanic gardens could be used to establish ex situ conservation collections.

Nearly one in every five species of reptiles in the world is threatened with extinction and thus is conservation dependent. In order to develop effective and targeted species conservation strategies, detailed information on their distribution, systematics and ecology are necessary. Information such as the natural history and in-situ reproductive behaviors would be crucial for highly threatened species that require ex-situ conservation measures. Agamid lizards are a major component of the global reptile diversity and a significant number are threatened due to habitat loss and other threats such as smuggling.

The Coronavirus disease 2019 (COVID-19) outbreak, forcing us to face unprecedented moments in the world. The huge devastating impact of the world due to the covid-19 attack causes the brink of no return. However, there is no proven and specific treatment for Covid -19. Very few medications have received Emergency Use of Authorization. A recent in vitro study was the first time to find out and to assess the antiviral effect of Ivermectin on COVID-19. The study showed that Ivermectin was active against COVID- 19-infected cells, was able to kill effectively almost all viral particles within 48 h. In these moments of crisis, FDA-approved ivermectin is a ray of hope. Bangladesh Journal of Infectious Diseases 2020;7(2):95-98
