Tobacco (Nicotiana tabacum L.) is a plant used as a mixture of cigarettes, and recreational media especially for men. This study aimed to identify variations, and determine the relationship between tobacco cultivars in Central Java and Yogyakarta based on macromorphological and micromorphological characters. Sampling locations are determined by surveying locations in both regions. Tobacco samples found include 5 cultivars in Central Java namely 'Mantili', 'Uler Magetan', 'Garut', ‘Gober Boyolali’, 'Manila', and 3 cultivars in Yogyakarta namely 'Siluk', 'Java', and 'Virginia'. Characterization with 23 qualitative macromorphological characters including leaves, and stems, with 9 qualitative and quantitative micromorphological characters including trichome and stomata. Descriptive data analysis is done to obtain the typical character of each cultivar, followed by numerical analysis including scoring characters processed with MVSP (Multi Variate Statistical Package), clustering with UPGMA (Unweighted Pair Group Method with Averages), and calculation of similarity coefficients with Simple matching formula. The results showed variations in the macromorphological characters including the shape of the leaf lamina, the base of the leaf, the absence of leaf stalks, and type of leaf venation. Tobacco has anisositic stomata, and varies in terms of length, width, and density of stomata. Tobacco trichomes are glandular. The result dendrograms form two clusters (A and B) with the similarity index of each cluster above 0.80. Cultivars with close relationships such as 'Siluk'-'Java', and far relationship like 'Java'-'Manila'.

Botanical gardens have several aims, among which is to increase awareness of plant diversity, to study it, and to conserve it. The Francisco Javier Clavijero Botanical Garden at the Instituto de Ecología, in Xalapa, Mexico, curates the Mexican national living national bamboo collection. In 2010 a new Otatea species was collected, described and cultivated in the living bamboo collection. Two years after being planted, this bamboo began to flower in the summer of 2012. I decided to visit the type locality and I found the entire population flowering. Based on collected specimens, the synflorescences and spikelets of Otatea ramirezii are described and these structures are compared with those of the known Otatea species described with flowers. The living national bamboo collection of Mexico is important for the preservation of native species and, given that the flowering cycles of most bamboo species are not known, for the documentation of their life cycles.

Orchid is one of the most popular ornamental plants in the world. One of the orchid genera that is collected in a large number and known to have high morphological variations in the Liwa Botanical Garden is Dendrobium. However, to date, many Dendrobium collections have not been identified. Given the urgency of identification and the limitations of specimens in the field, especially flower organs, this study is important. This study aims to determine variations in morphological characters, phenetic relationships, and to identify Dendrobium collections based on leaf morphological characters in the Liwa Botanical Garden. Five accessions of Dendrobium were collected, namely CAT140, CAT 144, CAT 271, CAT 274, and IR015. Observation of 11 morphological characters leaves showed that leaf had high variations. The phenetic relationship based on the Gower similarity value and the UPGMA method shows that the Dendrobium in the Liwa Botanical Garden can be classified into 2 main groups formed with a similarity index value of 0.813. Based on Principle Component analysis values, it is known that the characters that have a large influence on grouping are the ratio of leaf length and width, leaf cross section, and leaf arrangement. The phenetic dendrogram topology is supported by the morphological character classification. The results of this study are expected to be basic information in the identification of natural orchids and conservation efforts in the Liwa Botanical Garden.

Tree plants in the landscape have a very important function for the life of other living things. As an important element in the landscape, the selection of tree species in the landscape needs to be considered. With respect to aesthetic function in the landscape, the selection of tree species may vary based on their physical appearance. The general aim of this research is to study the potential of local tree collection at the Bogor and Cibodas Botanical Garden to fulfill the aesthetic function in the landscape. As for the specific purposes are as follows: (1) assess the ecological distribution of local tree collections of Bogor and Cibodas Botanical Gardens, (2) review the aesthetical performance of local tree collections of Bogor and Cibodas Botanical Gardens, and (3) provide recommendations on the utilization of Java native tree species for aesthetic functions in the landscape.This research was conducted at Cibodas Botanical Gardens and Bogor Botanical Garden. The research procedure is divided into 3 stages: (1) collection and grouping of tree data, (2) processing and analysis of tree data, and (3) assessment of tree aesthetic quality. The results of the processing and assessment of the tree data were used as a reference for the recommended tree species that are potential to be developed. Data of collected tree species were further processed and analyzed based on habitat distribution and morphological characteristics. Furthermore, the Key Performance Index (KPI) assessment technique is used to give value to each criterion. Stages of tree aesthetic quality assessment was done simulated using Scenic Beauty Estimation (SBE) method. Based on the research that has been done, the biodiversity of local tree species found in both botanical gardens is quite high as 223 species can be found in Cibodas Botanical Garden and 469 species can be found in the Bogor Botanical Garden. From this result, there are 52 species that can be found both at Cibodas Botanical Gardens and Bogor Botanical Garden. Then it can be concluded that the distribution of the habitat of local species of Java trees collection of KRB and KRC spread in each region. The highest number is a species of tree scattered throughout Java Island (327 species), from western Java (172 species), from west and central Java (80 species), central Java (21 species), central and eastern Java (13 species), western and eastern Java (11 species), and eastern Java (10 species). In addition, local tree species also have a range of habitat heights ranging from coastal zones (0 masl) to mountain zones (3100 masl). In the tree species studied in KRC and KRB, based on the criteria of aesthetic assessment there were 72 species of trees including into good category, 287 species in medium category, and 23 species in the bad category.
