Validasi, Distribusi Dan Pemanfaatan Acanthaceae Di Jawa [Validation, Distribution and Potential Uses of Acanthaceae in Java]

Acanthaceae published in Flora of Java has had significant change especially for nomenclature, distribution and potential uses; thus it affected species names of collections of Acanthaceae in Herbarium Bogoriense of The Indonesian Institute of Sciences. It is therefore necessary to update information of Acanthaceae by conducting herbarium and field surveys as well as reviewing related publications. Validation of the species name, synonymous and distribution were carried out by using some online websites such as IPNI, Tropicos and The plantlist. Meanwhile, the potential uses were obtained from several publications. Examinations on herbarium specimens was conducted in the Herbarium Bogoriense, while field survey was carried out in several locations in Java. This study recorded a total of 164 species of Achantaceeae to which 53 were native in Java (Indonesia), 24 species become synonymous, and five other species have not been published. Some of them have potential chemical substances and uses

Begonia Hirtella Link DI JAWA [Begonia Hirtella Link in Java]

Begonia hirtella Link. is one of the introduced species that naturalized and grows wild in Java. This species has very good growing ability and potentially to be invasive at new habitat. Recently, there is no information about the status, existence and distribution of this species in Java. Consequently, it need to be informed about it status, presence and distribution more clearly. Collecting data from herbarium collections, internet connection, various references and some field trips were conducted. This information can improve knowledge and awareness of people as well as assisting monitoring and controlling for introduced plant species such as Begonia hirtella in Java, Indonesia

Batam Botanic Garden, Indonesia: Recommendation for Its Living Collections from Riau Archipelago Exploration

Batam Botanic Garden is a relatively new botanic garden in Indonesia that is assisted by and under collaboration with Bogor Botanic Garden. Recently, a team of Bogor Botanic Garden and Research Center for Biology?LIPI conducted flora exploration in Riau Archipelago, particularly on Karimun Island, Sugi Island and the surrounding areas. The aim of this exploration is to inventory the flora diversity in Riau Archipelago and to enrich living collection of the Batam Botanic Garden. Based on the data gathered from this inventory, we recommend 20 selected plant species with significant conservation value to be targeted for and included in the living collections of Batam Botanic Garden. Five of them (Aquilaria malaccensis, Ceriops decandra, Hopea ferruginea, Pterocarpus indicus and Vatica hullettii) need more attention to be conserved due to their IUCN red list status
