Abstract

Dioscorea tuber has many benefits, for example as food or as traditional medicine. The high carbohydrate and protein contents make this plant suitable as a food. However, the presence of crystal oxalate, that causes irritation is an disadvantage aspect on the development of this species. Both of wild and cultivated species will assure the gene flow which is important in efforts to improve the tuber quality should be examine further.  This research aimed to observe the biodiversity of Dioscorea in Bali and Lombok, to recognize the utilization and to reveal their nutrients (carbohydrate, protein and fat) and also the contents of calcium oxalate. The results showed that there are five Dioscorea spesies, namely  Dioscorea alata L. (ubi) (11 cultivars), Dioscorea esculenta (Lour.) Burkill (ubi aung), Dioscorea hispida Dennst. (gadung), Dioscorea bulbifera L. and Dioscorea pentaphylla L.   The highest carbohydrate content (87,42% ) is found in D. alata (ubi ungu cultivar) from Lombok,  while the highest protein content (5,05%.) is found in D. alata (ubi dadap cultivar) from Singaraja, Bali.  Furthermore, the highest percentage of fat content (0,85%) is found in D. bulbifera from Karangasem, Bali, whereas the high quantity of glaucomannan (44,52%.) id found in D. pentaphylla from Tabanan, Bali, while D. esculenta from Jembarana, Bali has the  highest calcium oxalate (0,57%), and D. alata (ubi injin cultivar) from Karangasem, Bali has the least calcium oxalate (0,18%).

Abstract

The Lesser Sunda Islands of Indonesia are composed of small islands scattered from Bali to Timor Island. We analyzed a molecular phylogeny of Adiantum collected from Lesser Sunda Islands to reveal its phylogenetic relationships. A total of 12 species of Adiantum from this region and seven species from Java Island were collected and used in this study. Two cpDNA regions (rbcL and trnL-F) were chosen as markers and phylogenetic analyses were conducted using Neighbour-Joining (NJ) and Maximum Parsimony (MP) methods. The tree topologies reconstructed by NJ and MP from specimens used in this study and other species downloaded from GenBank are congruent in which trees are divided into five major clades. Adiantum species of Lesser Sunda Islands are not monophyletic and comprises three clades, i. e. Clade I composed of A. hispidulum group, Clade III composed of A. peruvianum group and Clade IV or A. caudatum group, each together with extra-Lesser Sunda samples. No sample from Lesser Sunda Islands examined is located in Clade II (A. tenerum group) and V (A. capillus-veneris group).

Abstract

Dicksonia is one of tree ferns species that can be found in Indonesian highlands. Due to their wide distribution this species was suggested to have genetic variation among their population. Samples from Bali, West Java (Cibodas) and East Nusa Tenggara were compared using the PCR-SSCP methods to detect genetic variation of trnL-trnF intergenic spacer from the cpDNA plastid genome. Sample from Bali and West Java (Cibodas) did not morphologically and genetically variated, but they were variated to samples from East Nusa Tenggara.

Wita Wardani & Bayu Adjie. 2017. Daftar Jenis-jenis Pteridofita dari Pulau Enggano. Floribunda 5(6): 209–219. — Daftar 61 jenis paku-pakuan dan kerabat paku dilaporkan untuk pertama kalinya. Seluruh jenis yang terdaftar merupakan jenis-jenis yang tersebar luas. Luas dan jarak Pulau Enggano dari Sumatra tidak memungkinkan timbulnya keunikan pada keanekaragaman paku-pakuan dan kerabatnya. Satu jenis dinilai sebagai jenis yang belum lama ternaturalisasi, yakni Adiantum latifolium. Epifit (litofit) menyusun 44% dari daftar ini. Hutan Lindung Koha Buwa-buwa merupakan area penting yang menjadi tempat hidup hampir 50% keanekaragaman paku-pakuan di pulau ini.Kata kunci: Enggano, Keanekaragaman, Koha Buwa-buwa, Paku-pakuan.Wita Wardani & Bayu Adjie. 2017. Checklist of Pteridophyte Flora of Enggano Island. Floribunda 5(6): 209–219. — List of 61 pteridophyte species from the Island of Enggano is presented for the first time. None of these are endemic, all are wide spread species. The size and distance of Enggano from its mainland is insufficient to develop distinctiveness in diversity of pteridophyte. One in the list is believed to be newly naturalized, i.e. Adiantum latifolium. Epiphyte (lithophyte) constitutes 44 % of the list. The protected forest Koha Buwa-buwa is the important area that shelter nearly 50% of total pteridphyte diversity in the island.Keywords: Enggano, Diversity, Koha Buwa-buwa, Pteridophyte.

Abstract

The genus Calochlaena was separated from Culcita in 1988, and consisting of about five species. Based on cpDNA sequences of rbcL gene, the phylogenetic tree was made and C. javanica is nested within the genus and the rest of dicksonioid ferns. The description, distribution and spore morphology are presented.

Abstract

Adiantum or maidenhair fern is one of the largest genera in Pteridaceae. We survey their species diversity in Lesser Sunda Islands, Indonesia through the living collection and herbarium examination. Seventeen species of Adiantum were recorded. including five species that considered as introduced and naturalized species. One species that grows naturally, Adiantum silvaticum, were previously known as endemic to Australia. However, this study revealed the new distribution of this species on Sumba and Flores.
