. Supiandi MI, Mahanal S, Zubaidah S, Julung H, Ege B. 2019. Ethnobotany of traditional medicinal plants used by Dayak Desa Community in Sintang, West Kalimantan, Indonesia. Biodiversitas 20: 1264-1270. Dayak Desa community has a long history of using medicinal plants as one of the methods to overcome health problems. Along with the advancement of science, the influx of foreign cultures and environmental degradation, traditional knowledge about medicinal plants and their utilization are only owned by the old generation. This study, therefore, aimed to identify medicinal plants used by Dayak Desa community who lives in Pakak Village. To collect information from the community, a survey was conducted in June 2017. Snowball sampling method was utilized to select 6 informants from whom information related to the plants’ local names, the used parts of the plants, and the ways of managing and using the plants for curing illnesses was obtained through structured interviews. Data analysis was qualitative and quantitative. The results show that 25 species of medicinal plants from 9 families. The most widely used part of the plants is the leaves. The people in the community boil the leaves and drink the extract. Based on the results of the ICS analysis, the plant's value ranged from 1 to 24. The highest value was observed in keladi (Colocasia esculenta L.) and the lowest value was found in kayu kenanga (Canangium odoratum Baill).

A phylogenetic analysis of the genus Homalomena (Araceae: Homalomeneae) based on the nITS region is presented. Eighty-nine taxa are included; representing all Asian supergroups, several Neotropical species currently assigned to Homalomena, and selected species of Philodendron. Asian Homalomena is well supported as monophyletic and excludes Neotropical Homalomena. The Cyrtocladon supergroup is monophyletic after transferring the Insignis complex and Havilandii complex into the Punctulata supergroup. The Homalomena and Chamaecladon supergroups are well supported. A reduced phylogeny of 20 accessions representing 15 taxa was used for subsequent morphological and chemical marker optimization. A constricted spathe and four stamens per staminate flower are plesiomorphic for Homalomena. Staminodes among the pistillate zone are lost three times independently in Homalomena supergroup, Punctulata supergroup, and H. vivens. Chemical markers identified from liquid chromatography-mass spectroscopy profiling provided an independent set of markers that further support the separation of Neotropical species of Homalomena from the Asian taxon. Three chemical markers at Rt 2.55 min, 2.69 min, and 2.90 min are shared among the majority of taxa sampled for Asian Homalomena, and Neotropical species currently assigned to Homalomena show two unique peaks at Rt 3.25 min and 3.54 min. Five chemical markers support the Cyrtocladon supergroup with the exception of Homalomena vivens. A chemical marker at Rt 3.60 min is plesiomorphic for the Chamaecladon, Homalomena and Punctulata supergroups. A chemical marker at Rt 2.80 min is apomorphic for the Chamaecladon supergroup, with a separate gain in H. punctulata. This study supports removal of the Neotropical species from Homalomena, redefines the morphological boundaries of Homalomena sensu stricto (i.e. the Asian species), and supports and refines the grouping of Asian species into supergroups.

A summary of the aroids of the Flora Malesiana region at the rank of genus is provided. Identification notes for each genus and, where appropriate, their major subdivisions are given. The last monograph and all subsequent key literature is cited for each genus, and also compiled as a general entry. All 42 of currently recognized indigenous Malesian aroid genera (excluding three genera of former Lemnaceae) are detailed, and illustrated.

Biodiversitas 12: 7-11. Amorphophallus belongs to Araceae family that consists ofÂ more than 170 species worldwide and distributed predominantly in tropical countries, especially in Asia and Africa. The study ofÂ Amorphophallus in Bali and Lombok Islands had been conducted to reveal its diversity. Genetic study was also conducted amongÂ Amorphophallus paeoniifolius species to recognize the variation within the species. The fieldworks showed three speciesÂ Amorphophallus distributed in Bali, notably A. muelleri Blume, A. paeoniifolius (Dennst.) Nicolson, A. variabilis Blume and twoÂ species in Lombok, notably A. muelleri and A. paeoniifolius. Var. hortensis and var. sylvestris were two varieties of A. paeoniifolius thatÂ commonly found either in Bali or in Lombok. Genetic study on A. paeoniifolius indicated that there was no genetic variation in cpDNAÂ region of trnL-F IGS within the species.

Homalomena agens is described and illustrated as a new species of the Chamaecladon Supergroup from Kalimantan Timur, Indonesian Borneo. A brief overview of the recent publication history of Homalomena in the humid Asian tropics, together with a review of the taxonomy of the Chamaecladon Supergroup in Borneo, and a key to described species in Borneo, is

The research of tree species distribution along the environmental gradients in Lowland Tropical Rainforest Pananjung Pangandaran Nature Reserve had been conducted. The study aimed to elucidate the relationship between tree species distribution with â‰¥10 cm dbh and some measured environmental gradients, namely soil pH and moisture, soil depth, litter thickness, light intensity, altitude, slope, and the distance of plot from coastal line. A number of 125 of 10x10 m2 quadrats were established randomly in four transects. The results indicated that Rhodamnia cinerea was the species having the highest presence. Ordination technique using Canonical Correspondence Analysis (CCA) suggested that tree species were less evenly distributed along the measured environmental factors with Eigenvalue 0,387. Altitude was themost important environmental factor affected tree species distribution, soil moisture as well as light intensity.Key words: canonical correspondence analysis, distribution, lowland tropical rainforest, Pananjung Pangandaran

The study aimed to gain information about tree species domination and association was conducted in lowland tropical forest of Tangkoko Nature Reserve. The tree with â‰¥10 cm dbh censused with quarter method. The result showed that Palaquium sp. having the highest domination species with Index Importance Value 21.05, as well as Cananga odorata Hook.f. & Thoms. and Dracontomelon dao (Blanco) Merril & Rolfe. There was one couple species that had positive association among seven main species composition in area study, that was C. odorata with kayu kapur. Generally, the other couples species had negative association, so there was no tolerance to exist in the same area and no mutualism interrelationship especially in habitat grouping.Â© 2008 Jurusan Biologi FMIPA UNS SurakartaKey words: Palaquium sp., domination, species association, Tangkoko Nature Reserve
