Abstract

Abstract

Taxonomic study of beard moss (Usnea spp) at Priangan, was carried out by using morphological, anatomical and chemical's characters. Sample have taken from five area, they are Jayagiri conifer forest (Bandung), Rancakalong conifer forest (Sumedang), Kamojang conifer forest ( Garut), Munjul conifer forest (Ciamis) and Cigorowong conifer forest ( Tasikmalaya). Morphological observation was done on thallus and anatomical observation in medulla, axis and ratio of cortex : medulla : axis. While chemical analysis was conducting by colour test and crystal test. The identification result founded the eleven species, i.e. Usnea baileyi, U.ceratina, U.cornuta, U.filipendula, U. flexilis, U. flexuosa, U.florida, U.glabrata, U.hirta, U. longissima and U. trichodea. Morphological characters that can be used for distinguished of eleven species of Usnea are medulla shape, axisshape, radius of cortex, radius of medulla and diameter of axis. Chemical characters distinguished are reagent K,C, KC and IKI. Based on that characters the key identification have made for Usnea species founded at Priangan and de3scription were arranged for genus and species level. Phenetic analysis done by using NTSY Spc versi 2.0, resulted a Dendrogram which the eleven species of Beard moss can be divided into three branches. The first branch consist of U.baileyi and U.ceratina, the second are U.cornuta, U.flexilis, U.florida, U. flexuosa and U.glabrata and the third branch branch consist of U.filipendula, U.hirta, U.trichodea and U.longissima.
