A Taxonomic Revision and Phylogenetic Analysis Of Hornstedtia Retz. (Zingiberaceae) in Sumatra
No full textThe genus Hornstedtia Retz. of Zingiberaceae consists of approximately 89 species, all of which are herbs. The genus is distributed from India to the Solomon Islands and northern Queensland. The main diversity is within Malesia, particularly in Indonesia and Malaysia. The diversity of the genus in Sumatra is less well studied compared to neighbouring areas like the Malay Peninsula and Borneo.
The aim of the current study is to study the species in Sumatra and adjacent small islands covering the morphology, including pollen, taxonomy and phylogeny based on molecular data with the ITS marker in order to obtain a better
understanding of the relationship ofthe species and approximate genera.
The present study recognises nineteen taxa in Smnatra, consisting of 16 species and three varieties. One species is proposed as new to science, namely H. panyabungemsis Nurainas, one is proposed as a new variety, namely H. tomentosa var. viridis Nurainas, two are proposed as new status (H. fusiformis vaj.fusiformis (Holttum) Nirainas and H. fusiformis var. grandis (Ridl.) Nurainas), two are proposed as new combinations (H. padangense (K Schum.) Nurainas and H. vestita (K. Schum.) Nurainas & A.D. Poulsen).
The study of the pollen morphology shows that species of Hornstedtia from Sumatra has monad or monolete pollen. The polarity of pollen is either isopolar or heteropolar. Hornstedtia has big pollen of 69.02-86.71 um a long the polar axis and 57.12-72.51 um along the equatorial axis. The pollen are prolat, sferoidal or ovoid with no apertures and ruminate ornamentation. Morphology of the pollen has significant implication for differentiation between genera, but it is not necessary to distinguish between species
Analysis of Natural Hybrid Between Nepenthes gymnamphora Reinw. ex Nees with Nepenthes inermis Danser Based On Geometric Morphometrics
Get PDFAbstract - Recently, based on preliminary observations in the field of Nepenthes populations found in Mount Kunyit, Kerinci Regency, Sumatra, several Nepenthes species were found to live sympatrically, namely N. gymnamphora with N. inermis. On the other hand, a population of Nepenthes that is assumed to be a natural hybrid of the two species was also found. This unidentified taxon is very different from other Nepenthes in the habitat because it has intermediate pitcher characters with its parents. However, it is not yet known which taxon is the parent. In this study, the approach used was geometric morphometric analysis. The images were photographed from two different views, i.e., top view (lid) and front view (body with peristome). A total of 17 images (5 images from N. gymnamphora, 6 images from N. inermis and 6 images from its natural hybrid. All analyses used Momocs Package in R Statistical Software. The results of this study are variations in the shape of the pitcher of putative natural hybrids between N. gymnamphora and N. inermis species in the shape of the pitcher in front view and the size of the pitcher lid in lid view. Nepenthes individuals that have intermediate shape characters with both parents (N. gymnamphora and N. inermis) are natural hybrid individuals.

Systematic Literature Review: Study Ethnobotany of Family Zingiberaceae in Several Ethnic Groups in Sumatra
Get PDFEthnobotany reveals that the relationship between human life and plants is one that cannot be separated, One of the plant families that is most widely used in everyday life is Zingiberaceae, also known as the ginger tribe. Many local ethnic groups in Indonesia use the family Zingiberaceae as ingredients for medicines (ethnomedicin), ethno-economics, ethno-ecology, traditional or ritual processions, and ethnopharmacology. Local people from various ethnicities in the world take advantage of this family because of the large amount available in nature and its distinctive aroma and taste that are different from other families. Several ethnic groups have used the family Zingiberaceae as raw materials for traditional medicine, food ingredients, and cultural traditions for generations, namely the Lingga Malay ethnic group in the Riau Islands, the local Rupat Island community in Riau, the Toba Batak ethnic community in North Sumatra, and the Minangkabau ethnic group in West Sumatra.
Studi Morfometrik Hornstedtia leonurus (J.Koenig) Retz. (Zingiberaceae) dan Kerabat Dekatnya dalam Tribe Alpiniae di Sumatera Barat
Get PDFHornstedtia leonurus is one species of the Hornstedtia’s genera in Alpiniae Tribe (Zingiberaceae). It has unambiguous expressed some aberrations of morphological characters in what Hornstedtia should have. On the contrary, it has with it self some characters from other genera within the tribe of Alpiniae, such as Etlingera and Amomum. The research aimed to find some distorsion on morphological characters of the H. leonurus with its close selected sisters in Alpiniae Tribe (Etlingera megalocheilos and Amomum cardamomum) and determined their were characters relationship by a morphometric study. The materials collected from West Sumatra province (50 Kota, Padang and Sijunjung regency) on September until December 2015. Morphometric analysis used PAST version 2.17c and SPSS computer programs. Morphologically, H. leonurus closely related with E. megalocheilos rather than its sister in Hornstedtia genera (H. schypifera) and A. cardamomum.Keywords: Alpiniae, H. leonurus, morphometric, relationship, Zingiberaceae

INVENTORY OF CELASTRACEAE (PARUPUK-PARUPUKAN) SPECIES BASED ON HERBARIUM SPECIMENS OF ANDALAS UNIVERSITY (ANDA)
No full textCelastraceae has various benefits. However, research on the identification and distribution of Celastraceae species, particularly in Sumatra, is still limited. Therefore, further studies are needed on the identification and distribution of Celastraceae in Sumatra. The Herbarium of Universitas Andalas (ANDA) has a collection of Celastraceae specimens, most of which have not been identified to the species level. Given the high diversity of flora in Indonesia, especially in Sumatra, identifying Celastraceae species is an important step to better understand the potential of these plants. This study aims to determine Celastraceae species and their distribution based on specimens from Herbarium ANDA, which is expected to enrich scientific knowledge about biodiversity in Indonesia and open up opportunities for further utilization of the Celastraceae family. The method used is herbarium-based, involving the management of specimens from Herbarium ANDA. This study identified fifteen species from six genera: Celastrus, Euonymus, Glyptopetalum, Lophopetalum, Microtropis, and Salacia. The distribution of Celastraceae plants in Herbarium ANDA covers West Sumatra, North Sumatra, Riau, and one species from Kagoshima Prefecture, Japan. Most specimens are from West Sumatra, with the distribution detailed as follows: seven species from Padang; two species each from Solok, Lima Puluh Kota, Pasaman, and Mentawai; and one species from Agam and Pasaman Barat. In Riau Province, two species were found in Kampar, and in North Sumatra Province, one species was found in South Tapanuli.Keywords:Â Celastraceae, Distribution, Inventory, Species

Vegetation Analysis and Population Structure of Plants at Forest Area, Solok Regency, West Sumatra, Indonesia
Get PDFSolok Regency is a highland area in West Sumatra with a topography that varies between plains, valleys and mountains. The aim of this study was to determine the vegetation structure that affects the population of Bilongkiang (Zingiber sp.). This study used the quadratic method and determined the research location by purposive sampling with plot size determined based on the vegetation strata, namely: understorey and seedling (2x2 m2, poles (5x5 m2, and trees (10x10 m2). Data analysis was carried out qualitatively and quantitatively. Quantitative data analysis by calculating: Density (Kr), Frequency (Fr), Dominance (Dr), Importance Value Index (INP) and Diversity Index (H'). The results of the study found as many as 33 families consisting of 53 species with a total number of 79 individuals spread over two research locations which were divided into understorey plants/seedlings, poles and trees. The highest Important Value Index (INP) in Nagari Surian was found in the pole strata, which was 180.30% and in Nagari Talang Babungo, the INP was also found in the pole strata, which was 91.85%. This value is included in the high category. The diversity index (H') of plants in the study area is H' = 2.12, which means that the diversity of species in the study area is moderate
