The Diversity and Conservation of Piper (Piperaceae) in Bukit Barisan Selatan National Park, Lampung Province

Piper (Piperaceae) is an aromatic plant genus, some species of which can also be used as ornamental plants. We have carried out plant exploration in Bukit Barisan Selatan National Park (TNBBS) of Lampung Province, which is known as one of the centres of diversity for Piper species. This field exploration aimed to contribute to the inventory of Piper species in Sumatera. A purposive sampling method was employed. The work was carried out from 2011 to 2014 in four resorts of TNBBS, viz. Kubu Perahu Resort, Sukaraja Atas Resort, Pugung Tampak Resort and Sekincau Resort. The results revealed that there are 21 Piper species present in TNBBS; of which one species is a tree, six species are shrubs, and the other 14 species are climbers. All these species have been cultivated as collections in Bogor Botanic Gardens (West Jawa Province) and also in Liwa Botanic Garden (West Lampung Province), for ex-situ conservation purposes. Results of analysis of morphological characters are discussed along with information about the USAge of the species. A key to the species and maps showing their distribution are presented in the paper

KARAKTERISTIK KOLEKSI SPESIMEN TIPE BAMBU DI HERBARIUM BOGORIENSE, PUSAT PENELITIAN BIOLOGI – LIPI

The aim of this study is to explore information about the characteristics of collections of the type specimens of bamboo in Herbarium Bogoriense (BO) to obtain the infografic status of the collections. The study was conducted in April-May 2018 at BO, Research Center for Biology ‒ LIPI with direct observation method. The population, as well as the sample of the research, is the whole collections of type specimens of bamboo in BO. Data obtained by examining and recording the entire collection of type specimens of bamboo in BO. Characteristics that observed are species names, collectors, number and year of collection, discovery location, number of sheets, specimen conditions, the journal of publication and year, kind of type and duplicate location. Each of species name is validated before it is analyzed. The data were analyzed and presented qualitatively as the tables and charts. There are 107 species from 117 collection numbers of type specimens of bamboo in BO. Two numbers collection from two species is not found. The most type specimen is from Gigantochloa (20,5%). Approximately 63,5% of type specimens were published and/or proposed the combinations of names by LIPI researchers. Elizabeth A.Widjaja is the collector of the most type specimens (43,6%). The highest period (34,2%) of collection activities was in 1991-2000. About 62,6% of type specimens are collected from various islands in Indonesia. There are 577 sheets of type specimens in BO, 92% are in good condition and 8% is good enough. There are 51,3% of holotype specimens in BO, followed by isotype (30,8%), paratype (11,1%), lectotype (2,6%), neotype (2,6%), epitype (0,8%), and isosyntype (0,8%). As many as 50% holotypes has duplicates in more than two different of herbarium locations, the other 37% are without duplicates. About 56% of type specimens are published in the journal of Reinwardtia and 16,8% in Kew Bulletin
