The relationship between Litsea and related genera is currently unclear. Previous molecular studies on these taxa using cpDNA and nrITS were unable to produce well-resolved phylogenetic trees. In this study, we explored the potential of the rpb2 gene as a source of molecular information to better resolve the phylogenetic analysis. Although rpb2 was believed to be a single-copy gene, our cloning results showed that most species examined possessed several copies of these sequences. However, the genetic distance among copies from any one species was low, and these copies always formed monophyletic groups in our molecular trees. Our phylogenetic analyses of rpb2 data resulted in better resolved tree topologies compared to those based on cpDNA or nrITS data. Our results show that monophyly of the genus Litsea is supported only for section Litsea. As a genus, Litsea was shown to be polyphyletic. The genera Actinodaphne and Neolitsea were resolved as monophyletic groups in all analyses. They were also shown to be sisters and closer to the genus Lindera than to the genus Litsea. Our results also revealed that the genus Lindera is not a monophyletic group.

Pada HUT ke-198, Kebun Raya Bogor telah meresmikan Taman Koleksi Tumbuhan Obat yang dilengkapi lima jalur wisata edukasi, yang kemudian dikenal sebagai "Jalur Tumbuhan Obat". Sepanjang jalur wisata kita dapat mengetahui manfaat dari beragam tumbuhan obat, diantaranya adalah air rebusan rebung muda bambu kuning ternyata bermanfaat untuk mengobati penyakit hepatitis. Air seduhan bunga kenanga dapat mengobati nyeri otot dan sendi. Selain itu, segelas air perasaan jeruk purut hangat dapat melegakan pernapasan saat flu. Begitu banyak informasi tentang manfaat tumbuhan obat yang dapat kita gunakan. Oleh karena itu, kulik (kupas dan telisik) lebih cermat semua informasi terkait jenis tumbuhan obat dan manfaatnya. Selain itu, kita juga dapat memilih jalur wisata yang akan kita lalui karena setiap jalur memiliki waktu tempuh rata-rata satu jam, namun memiliki perbedaan pada kondisi topografi dan jumlah kalori tubuh yang akan terbakar saat menelusuri jalur wisata. Mari memulai petualang dengan membaca buku ini terlebih dahulu, kemudian langkahkan kaki untuk menikmati koleksi tumbuhan obat di Kebun Raya Bogor. Berangkat!

Abstract. Asra R, Silalahi M, Fijridiyanto IA. 2020. The practice and plants used in Besale ritual healing by the Anak Dalam Tribe in Nyogan Village, Jambi, Indonesia. Biodiversitas 21: 4529-4536. The Anak Dalam Tribe (ADT) is an indigenous ethnic which inhabits the center of Sumatra, especially in Jambi and South Sumatra Provinces, Indonesia. The ADT communities still maintain their traditional rituals; one of them is the Besale ritual healing (BRH). This study aims to analyze the diversity of plants used in BRH by the ADT in Nyogan Village, Jambi Province, Indonesia. The study was conducted with an ethnobotany approach through surveys using interviews and participatory observations. The total number of informants was six persons, namely the leaders and performers of the BRH. The data were analyzed qualitatively using descriptive statistics. The BRH is carried out by a dukunorsidi (shaman), bujang pembayun (dancers), biduan (singers), and inang (assistant). They combine ritual and treatment simultaneously to cure people who have severe illnesses. There are 21 species belong to 20 genera and 12 families of plants used in the BRH. The plants are used to build a hall (place for the BRH), "bird" ornament, and offerings. The most widely used part of the plant is the flowers (34,61%). The plants used in the BRH are fresh materials, which are burned, smoked, hung, and eaten during the ritual.

A revision of Dehaasia (Lauraceae) in Sumatra is presented. Eight species are recognized, including two newly described species (D. bandaharense and D. pilosa). A key to the eight species, descriptions and distribution maps of each species and illustrations of newly described species are provided. A neotype for D. incrassata is designated.
