Diospyros spp. is one of the genera of the Ebenaceae that has the highest distribution in tropical Asia and Africa. The high rate of deforestation in the tropics, so we need for preservation of species in conservation ex-situ at the Botanical Gardens. Research on the basic information and potential of Diospyros spp., the collection of the Bogor Botanical Gardens has been carried out through direct observation of all the Gardens’ Diospyros collections, both in the field and in the nursery. The results obtained as many as 32 species of Diospyros spp. which have been collected with the most specimens of the species Diospyros celebica, D. buxifolia, and D. maritima. Meanwhile, the source collection Diospyros spp. mostly from Sulawesi. The general potential of Diospyros spp. used as a valuable timber (ebony) and edible fruit.
Abstract. Irsyam ASD, Hariri MR, Peniwidiyanti, Irwanto RR. 2021. Short Communication: Note on the genus Dorstenia Plum. ex L. (Moraceae) in Java (Indonesia) and noteworthy information on the identity of D. bahiensis through ITS sequence. Biodiversitas 22: 3358-3363. Dorstenia Plum. ex L. grouped within tribe Dorstenieae in the Moraceae. The genus comprises 105 species that are distributed in the African, Asian, and Neotropical regions. Previous studies showed that Java Island has only one species of Dorstenia, namely D. contrajerva L. This exotic species was introduced a long time ago and naturalized in Java. The field survey was carried out in Banten, Jakarta, West Java, and East Java. Herbarium study was also carried out in Herbarium Bogoriense and Herbarium Bandungense. There are two additional species from Java, D. bahiensis Klotzsch ex Fisch. and C.A. Mey. and D. foetida (Forssk.) Schweinf. Dorstenia bahiensis originated from Eastern Brazil and was found naturalized in Mekarwangi Village, Lembang, Bandung Barat regency, Indonesia. Dorstenia foetida is native to Africa and is only found as a popular cultivated plant. A molecular approach was carried out to provide the right identity of D. bahiensis because it has been mistakenly labeled as D. elata by a Javanese horticulturist. The internal transcribed spacer (ITS) sequence separated and distinguished both D. bahiensis and D. elata into different clades, which makes the popular name for D. elata actually D. bahiensis. Based on this study, there are three species of exotic Dorstenia in Java. The descriptions, photographs, and further discussions are provided.
AbstrakInformasi mengenai suku Euphorbiaceae di Pulau Jawa telah direkam dalam buku Flora of Java Volume 1 oleh C.A. Backer and R.C. Bakhuizen van den Brink Jr. Meskipun demikian, informasi terkini mengenai Euphorbiaceae di Jawa belum tersedia sejak buku tersebut terbit. Beberapa jenis tambahan telah ditemukan dari Jawa dan penelitian ini bertujuan untuk melaporkan informasi tambahan mengenai Euphorbiaceae yang ada di Jawa. penelitian telah dilakukan di Banten, Jawa Barat, Jawa Tengah, Jawa Timur, dan Yogyakarta pada bulan Maret hingga September 2019. Hasil penelitian menunjukkan adanya suatu marga tambahan di Jawa, yaitu Cnidoscolus Pohl. Marga tersebut hanya terdiri dari satu jenis saja di Jawa, yaitu C. aconitifolius (Mill.) I.M. Johnst. Secara taksonomi, jenis ini dibagi menjadi 2 anak jenis, yakni C. aconitifolius subsp. aconitifolius and C. aconitifolius subsp. polyanthus (Pax & K.Hoffm.) Breckon. Berdasarkan bentuk bunga betinanya, spesimen dari Jawa telah diidentifikasi sebagai C. aconitifolius subsp. aconitifolius. Tumbuhan ini berasal dari Meksiko dan Mesoamerika dan telah umum dibudidayakan sebagai tanaman sayur di Jawa. Di kawasan Malesia, C. aconitifolius telah dibudidayakan sebelumnya di Brunei, Singapura, dan Filipina. Oleh karena itu, keberadaannya di Jawa ditetapkan sebagai sebuah rekaman distribusi baru untuk kawasan Malesia.Abstract The information on Euphorbiaceae in Java island has been recorded in the Flora of Java Volume 1 by C.A. Backer and R.C. Bakhuizen van den Brink Jr. However, the latest information on Euphorbiaceae of Java has not been provided since the book was published. Several additional species have been found from Java and this study aims to report additional information on Euphorbiaceae of Java. The study was carried out in Banten, West Java, Central Java, East Java, and Yogyakarta from March to September 2019. The result of this study shows that there is one additional genus in Java, namely Cnidoscolus Pohl. The genus only consists of 1 species in Java, namely C. aconitifolius (Mill.) I.M. Johnst. Taxonomically, the species was divided into 2 subspecies, i.e. C. aconitifolius subsp. aconitifolius and C. aconitifolius subsp. polyanthus (Pax & K.Hoffm.) Breckon. Based on the pistillate flowers shape, the specimens from Java was identified as C. aconitifolius subsp. aconitifolius. The plant is native to Mexico and Mesoamerica and it was commonly cultivated in Java as vegetable crops. In Malesia, C. aconitifolius was previously cultivated in Brunei, Singapore, and The Philippines. Thus, its presence in Java was considered as a newly distributional record for Malesia region.
