Nothaphoebe Blume is a genus of the Lauraceae or Medang-medangan family, and is included in the Persea subgroup together with the genera Alseodaphne, Dehaasia, Persea, and Phoebe. Information on the ...diversity of Nothaphoebe in Sumatra, especially in Lampung province, has never been reported. Therefore, the aim of this study was to understand the morphological characters and species of Nothaphoebe occured in Lampung. The morphological characters observed included twigs, leaf shape, flowers, and fruits. The results of morphological characterisation show that there are five species of Nothaphoebe, i.e., Nothaphoebe falcata, Nothaphoebe foetida, Nothaphoebe macrocarpa, Nothaphoebe magnifica, and Nothaphoebe umbelliflora. Identification key for species, descriptions of each species and distribution maps are presented in this article. Keywords: Herbarium Bogoriense, Lauraceae, Morphology, Nothaphoebe, Lampung Province
We present a 517-gene phylogenetic framework for the breadfruit genus Artocarpus (ca. 70 spp., Moraceae), making use of silica-dried leaves from recent fieldwork and herbarium specimens (some up to ...106 years old) to achieve 96% taxon sampling. We explore issues relating to assembly, paralogous loci, partitions, and analysis method to reconstruct a phylogeny that is robust to variation in data and available tools. While codon partitioning did not result in any substantial topological differences, the inclusion of flanking non-coding sequence in analyses significantly increased the resolution of gene trees. We also found that increasing the size of datasets increased convergence between analysis methods but did not reduce gene tree conflict. We optimized the HybPiper targeted-enrichment sequence assembly pipeline for short sequences derived from degraded DNA extracted from museum specimens. While the subgenera of Artocarpus were monophyletic, revision is required at finer scales, particularly with respect to widespread species. We expect our results to provide a basis for further studies in Artocarpus and provide guidelines for future analyses of datasets based on target enrichment data, particularly those using sequences from both fresh and museum material, counseling careful attention to the potential of off-target sequences to improve resolution.

We present a densely sampled phylogenomic study of the mulberry tribe (Moreae, Moraceae), an economically important clade with a global distribution, revealing multiple losses of inflexed stamens, a ...character traditionally used to circumscribe Moreae. Inflexed stamens facilitate ballistic pollen release and are associated with wind pollination, and the results presented here suggest that losses of this character state may have evolved repeatedly in Moraceae. Neither Moreae nor several of its major genera (Morus, Streblus, Trophis) were found to be monophyletic. A revised system for a monophyletic Moreae is presented, including the reinstatement of the genera Ampalis, Maillardia, Taxotrophis, and Paratrophis, and the recognition of the new genus Afromorus. Pseudostreblus is reinstated and transferred to the Parartocarpeae, and Sloetiopsis is reinstated and transferred to the Dorstenieae. The tribe Olmedieae is reinstated, replacing the Castilleae, owing to the reinstatement of the type Olmedia and its exclusion from Moreae. Streblus s.str. is excluded from Moreae and transferred to the Olmedieae, which is characterized primarily by involucrate inflorescences without regard to stamen position. Nine new combinations are made.

Yasper Michael Mambrasar, Taufik Mahendra, Megawati & Deby Arifiani. 2021. Catatan pada Rumput Kebar (Oxalidaceae). Floribunda 6(6): 220–224. — Rumput Kebar merupakan tumbuhan yang banyak ...dimanfaatkan sebagai obat dan penyubur kandungan. Sampai saat ini masih dijumpai penggunaan nama ilmiah untuk rumput kebar dengan menggunakan nama yang tidak valid. Di samping itu penggunaan nama lokal rumput Kebar juga mengarahkan pada dugaan bahwa jenis yang dimaksud masih berkerabat dengan rumput-rumputan (Poaceae). Hasil pengamatan spesimen herbarium dan studi literatur mendapatkan bahwa nama ilmiah rumput kebar adalah Biophytum umbraculum Welw dan B. petersianum Klotzsh merupakan sinonim. Daerah penyebaran rumput Kebar juga dibahas dalam artikel ini.
Actinodaphne quercina Blume (Lauraceae) is a narrow endemic tree, known only from the sterile type specimens collected in 1841 from Banten Province, Indonesia. Since its first collection, there have ...been no additional records of the species, and it is not present in any ex situ conservation. According to the IUCN Red List, the conservation status of A. quercina is Critically Endangered. Therefore, this study aimed to report on the rediscovery of A. quercina 180 years after its last collection. The current status of the species distribution, habitat preferences, and population size and structure was presented. The species description based on the morphology was created and taxonomic position was also defined based on a DNA barcoding analysis. Furthermore, the conservation status of the species according to the IUCN Red List Category and Criteria was updated. Plant materials were collected to serve as ex-situ living collections for the first time at the Bogor Botanic Gardens to enhance the conservation of the species.

Tropical forests occupy small coral atolls to the vast Amazon basin. They occur across bioregions with different geological and climatic history. Differences in area and bioregional history shape ...species immigration, extinction and diversification. How this effects local diversity is unclear. The Indonesian archipelago hosts thousands of tree species whose coexistence should depend upon these factors. Using a novel dataset of 215 Indonesian forest plots, across fifteen islands ranging in area from 120 to 785 000 km2, we apply Gaussian mixed effects models to examine the simultaneous effects of environment, earthquake proximity, island area and bioregion upon tree diversity for trees ≥ 10 cm diameter at breast height. We find that tree diversity declines with precipitation seasonality and increases with island area. Accounting for the effects of environment and island area we show that the westernmost bioregion Sunda has greater local diversity than Wallacea, which in turn has greater local diversity than easternmost Sahul. However, when the model includes geological activity (here proximity to major earthquakes), bioregion differences are reduced. Overall, results indicate that multi‐scale, current and historic effects dictate tree diversity. These multi‐scale drivers should not be ignored when studying biodiversity gradients and their impacts upon ecosystem function.

During the environmental impact study for a proposed nickel mine near Weda Bay on Halmahera in North Moluccas (Maluku Utara Province), Indonesia, two unknown Euphorbiaceae were discovered. ...Morphological comparisons and molecular phylogenetic analyses using four markers (plastid trnL‐F and rbcL, and nuclear ribosomal internal transcribed spacer and external transcribed spacer) indicated that they should be recognized as constituting a new, distinct genus of two species, which are described and illustrated here as Weda fragarioides and Weda lutea. The new taxa are members of the Australasian tribe Ricinocarpeae in subfamily Crotonoideae, and they are most closely related to Alphandia. In contrast with the otherwise mostly sclerophyllous Ricinocarpeae, Weda possesses stellate to dendritic hairs, large, long‐petiolate, glandular leaves, and inflorescences with a pair of large, leafy, subopposite bracts. The two narrowly distributed species are distinguished from each other by vegetative and floral features, molecular data, and elevational preferences. Leaf elemental analysis of Weda indicated manganese, but not nickel, accumulation. Newly resolved generic relationships and potential morphological synapomorphies within Crotonoideae are discussed, and the circumscription of Ricinocarpeae is expanded from 7 to 11 genera.
