Abstract
Lichen of the genus Usnea are used as a traditional herbal remedies. This genus has the thallus which is very similar among species, so it is very difficult to distinguish. Based on morphological character, identification of species in Indonesia is still limited. Morphological characters is can be used to identify in family and genus only. The molecular character based on DNA Barcode of Internal Transcribed Spacer (ITS) rDNA sequences which has conserved region (5.8S) and varied region (ITS1 and ITS2) is needed to strengthen and support the identification and phylogenetic analysis. The objective of this research was to identify and make phylogenetic analysis of Usnea species from the forest of Gunung Lawu, Center Java and Turgo, Yogyakarta. Phylogenetic tree was constructed with Maximum Likelihood (ML), the model of evolution Kimura-2 parameter with the bootstrap 1000. The result of phylogenetic tree reconstruction show within main two clades, section Usnea and Eumitria in the genus Usnea. The ITS rDNA sequence was able to identify most of the Usnea, but do not support the separation of the lichens Usnea pectinata and Usnea baileyi as distinct species.

Abstract
A character that is inherited from parents to offspring is influenced by gene action. Genes that control plant character can be influenced by additive, epistatic or dominant gene action. The purpose of this study was to determine the inheritance of the morphological characters of leaves, pods and soybean seeds through analysis of gene action and the number of genes in F2 populations of UM 3.2 x Argomulyo and UM 6.1 x Burangrang cross. The experiment was carried out at Indonesian Legume and Tuber Crops Research Institute (Iletri) Kendalpayak, Malang, Indonesia. Estimating the gene action and the number of genes was done by measuring the value of skewness and kurtosis. The suitability of inheritance patterns was analyzed by using the chi-square test. The results showed that the character of leaf length, leaf width, pod thickness and seed hilum length in the UM 3.2 x Argomulyo cross were influenced by the additive genes action with complementary epistatic influences while the character of the petiol length, pod length, pod width, seed length, seed width, and seed thickness was affected by additive gene action with duplicate epistatic effects. In UM 6.1 x Burangrang cross, the characters of leaf width, pod thickness, seed width, seed thickness and length of seed hilum were influenced by the additive genes action with complementary influences while the characters of leaf length, petiole length, pod length, pod width, and seed length were influenced by additives gene action with duplicate epistatic influence. The characters of petiol length, pod length, pod width, pod thickness, seed length, seed width, and seed hilum length were controlled by many genes.

Abstract
The majority of East Java people only use ferns as ornamental plants, even though ferns have potential in the medical field. The fern contains secondary metabolites so they are often called medicinal plants. Anatomical observations supported by histochemical tests can provide the type of secretory structure containing secondary metabolites and the content of secondary metabolites accumulated in these structures. This study began with exploration in the Tahura Soeryo area in June-July 2019. The results of the exploration were Pteris biaurita L., P. maricella V., P. quadriaurita Retz., P. linearis Poir, P. mertensiodes Wild , P. tripartita Sw., P. aspericaulis Wall. ex J. Agardh. , P. longipes D. Don, and P. linearis Poir. The rhizomes and fronds samples were cut across then tested with various types of reagents. Secondary metabolites were found in secretory tissues, vacuoles, and cytosol rhizomes and fronds of parenchymal cells in Pteris.
