Introduction. The study of the validation of scientific name validation at the species and family level is not widely known. This study aimed to provide information about the process of scientific name validation at the species and family level. Data Collection Method. Data were collected from online portal databases regarding the scientific name of plant species and family. Data was analyzed in a descriptive-narrative manner. Results and Discussions. Validation of the scientific name of species and family of plants can be conducted by searching the latest publications and using the online database portals i.e. IPNI, POWO, Tropicos, The Plant List, and GBIF. IPNI and The Plant List provide more information about species names compared to others. POWO and GBIF provide the status of the plant names and complemented with photographs of the plants, specimens, and distribution maps. Tropicos provides names of families according to the latest APG IV classification. Conclusions. Validation through the online portal database is the fastest way, however, validation through the publication of the latest plant taxonomy revision publications is the most recommended. Validation can be initiated by using the online database portals and then confirmed by tracking the latest revised plant taxonomy publications.
The distribution of Dinochloa scandens is unclear. World bamboo checklists suggest it is relatively widespread in Malesia. Here we clarify issues with herbarium specimen identification. Besides, a synonym name of D. scandens, namely D. macrocarpa collected from the Philippines, needs to be reviewed. The study aims to provide information on distribution and to review the synonym of D. scandens. The habitat preferences of D. scandens are also presented. We carried out targeted fieldwork at Gunung Halimun-Salak National Park in West Java in 2019 and extensive examination of herbarium specimens from Herbarium Bogoriense and online portals to accurately circumscribe this species. All data were analyzed descriptively. Distribution, altitude, and rainfall maps for D. scandens were produced with ArcGIS Pro. Our examination on the specimens suggests that D. scandens is indeed endemic to West Java and Banten Provinces in Indonesia. This bamboo species can be found in lowland to mountain forests with an altitude of 20-1400 m, in areas with annual rainfall between 3000-4000 mm. We support D. macrocarpa as an accepted name for a bamboo species from the Philippines and remove it from synonymy with D. scandens due to clear differences in the fruit compared to specimens of D. scandens across its range.
<p>Pulau Payung terbentang di hilir Sungai Musi dan Telang, Kecamatan Sungsang, Kabupaten Banyuasin II, Provinsi Sumatra Selatan. Pulau Payung terbentuk di wilayah estuari dan memiliki ekosistem air payau. Walaupun berukuran kecil, Pulau Payung dilaporkan memiliki keanekaragaman jenis-jenis tumbuhan mangrove sejati yang cukup tinggi. Sayangnya, laporan tentang keanekaragaman jenis flora secara menyeluruh di Pulau Payung belum tersedia. Penelitian ini bertujuan menyediakan informasi keanekaragaman jenis flora dan status konservasi mangrove di Pulau Payung. Pengumpulan data keanekaragaman flora di Pulau Payung dilakukan dengan menggunakan metode pengumpulan data taksonomi melalui koleksi sampel material tumbuhan. Sampel tumbuhan yang dikoleksi selanjutnya diawetkan menjadi herbarium dan disimpan di Herbarium Bogoriense (BO). Spesimen herbarium diidentifikasi menggunakan spesimen acuan yang tersimpan di BO dan referensi terkait. Hasil identifikasi divalidasi melalui referensi yang relevan dan portal basis data daring. Terdapat 36 jenis dari 28 marga dan 22 suku tumbuhan yang terekam di Pulau Payung, yakni 16 jenis tumbuhan mangrove sejati dan 20 jenis tumbuhan mangrove asosiasi. Acanthaceae, Fabaceae, dan Rhizoporaceae merupakan tiga suku dengan jumlah jenis terbanyak. Kendatipun seluruh jenis tumbuhan di Pulau Payung memiliki status keterancaman dengan tingkat risiko rendah (least concern/LC), tetapi potensi hilangnya keanekaragaman tumbuhan di Pulau Payung mungkin dapat terjadi di masa mendatang.</p>
The revision of Ampelocissus was performed by observing the anatomical character of Ampelocissus leaves. The leaves were collected from 33 collection numbers of Herbarium Bogoriense (BO) and four collection numbers from Sumatra exploration. The purpose of this study is to update the information of diversity and to support species concept delimitation of Ampelocissus based on the anatomical study, especially on the sterile plant. Anatomical characters were observed on nine species and one variety of Sumatran Ampelocissus. Ampelocissus species is varied by the anatomical characters, i.e.: shape of the anticlinal wall of abaxial and adaxial epidermal cell, number of palisade layers, upper epidermal cell thickness, leaf thickness, presence of papillae on stomata neighboring cell, type, and shape of calcium oxalate crystals, also stomata position. The cluster analysis of Ampelocissus in Sumatra based on 16 anatomical characters showed the coefficient similarity in the range of 0.48 - 0.81. The research showed that the leaf anatomical characters can be used as additional characters to distinguish the species of Ampelocissus. Keywords: calcium oxalate crystals, diversity, papillae, similarity coefficient, species concept ABSTRAK Ciri Anatomi Ampelocissus (Vitaceae) di Sumatera Revisi Ampelocissus dilakukan dengan mengamati ciri anatomi daun dari marga Ampelocissus. Sebanyak 33 nomor koleksi Herbarium Bogoriense (BO) dan empat nomor koleksi hasil eksplorasi di Sumatera digunakan. Penelitian ini bertujuan untuk memperbarui informasi mengenai keanekaragaman dan mendukung konsep jenis Ampelocissus berdasarkan ciri anatomi, terutama pada tumbuhan steril. Studi anatomi dilakukan pada sembilan jenis dan satu varietas Ampelocissus di Sumatera. Jenis-jenis Ampelocissus di Sumatera bervariasi pada ciri anatomi yaitu bentuk dinding antilkinal sel epidermis pada bagian abaksial dan adaksial, jumlah lapisan jaringan tiang, ketebalan sel epidermis atas, ketebalan daun, kehadiran papila, jenis dan bentuk kristal kalsium oksalat, serta posisi stomata terhadap sel epidermis pada bagian abaksial daun. Analisis pengelompokan Ampelocissus di Sumatera menggunakan 16 ciri antomi dan menghasilkan fenogram dengan koefisien kemiripan 0,48 - 0,81. Ciri anatomi daun dapat digunakan sebagai ciri tambahan yang memiliki nilai taksonomi dalam membedakan jenis-jenis Ampelocissus di Sumatera.
