“…However, in a dry environment in both the adaxial and abaxial parts, the density of stomata required by plants is not much. This is because the higher the stomata density, the higher the water loss (Bertolino et al, 2019;Rindyastuti & Hapsari, 2017). Then the stomata of dicot plants are generally scattered, in contrast to monocot plants such as orchids, which have a parallel pattern to the epidermis arrangement and are located in a row (Haryanti, 2010;Rudall et al, 2017).…”

“…Then the stomata of dicot plants are generally scattered, in contrast to monocot plants such as orchids, which have a parallel pattern to the epidermis arrangement and are located in a row (Haryanti, 2010;Rudall et al, 2017). According to research by Rindyastuti & Hapsari (2017), the density of stomata that is owned is directly proportional to the transpiration that occurs. The higher the stomata density, the more stomata found in one study area.…”

Stomata play an essential role in transpiration and metabolism. Orchids are Crassulacean Acid Metabolism (CAM) plants which are generally succulent leaf type. Orchids have several types of stomata, depending on habitat and environmental parameters that affect them. This study aimed to compare the stomata, including the anatomical structure, activity, and density of the orchids Dendrobium aphyllum and Arachnis flos-aeris. The method used was printing the surface of the leaves using glue and observed with a microscope. Data obtained were analyzed with the help of Image raster 3.0 and MS. Excel. In the present study, the stomata of D. aphyllum and A. flos-aeris are characterized by anomocytic type. The highest stomata density was obtained on the abaxial part of D. aphyllum 09.00 am 1177.78 um2. The adaxial leaves of both species are classified as low, or no stomata are found at all. The distance between the stomata on the abaxial leaves of D. aphyllum and A. flos-aeris is denser than the leaves' adaxial side. Stomata activity in orchids is related to orchids' adaptation process to the environmental parameters of their habitat. Stomata activity affects the transpiration process and CO2 fixation in orchid CAM metabolism.

“…Beberapa Glochidion juga memiliki tipe anomositik seperti pada G. hohenckeri (Thakur & Patil, 2014) dan pada penelitian ini tipe anomositik ditemukan pada G. philippicum. Tipe stomata parasitik juga ditemukan pada semua spesies Antidesma, hal ini memungkinkan bahwa karakter stomata untuk sebagian besar anggota genus Antidesma adalah parasitik (Gambar 1) dengan didukung hasil yang sama pada A. acidum (Patil & Jadhav, 2014) dan A. bunius (Rindyastuti & Hapsari, 2017). Sedangkan pada Breynia tipe stomata yang ditemukan yaitu anomositik dan parasitik (Gambar 1), hal ini sesuai dengan hasil penelitian Thakur dan Patil (2011a) pada B. nivosa.…”

“…Karakteristik pada genus Antidesma pada pengamatan yaitu jumlah jaringan tiang lebih dari satu lapis dengan bentuk dominan silinder pendek dan persegi serta sel penyusun epidermis atas yang tidak seragam (berbeda ukuran). Epidermis atas dengan bentuk yang tidak seragam juga ditemukan pada A. bunius (Rindyastuti & Hapsari, 2017). Breynia, Glochidion, dan Phyllanthus pada pengamatan ini umumnya memiliki jaringan tiang berbentuk memanjang kecuali B. macrantha yang memiliki bentuk jaringan tiang silinder pendek.…”

Abstrak Pengenalan ciri makhluk hidup dalam praktik identifikasi sebagian besar menggunakan ciri morfologi. Ciri anatomi memperkuat ciri morfologi atau menyelesaikan permasalahan kerancuan identifikasi secara morfologi. Penelitian ini bertujuan untuk mengetahui karakter anatomi daun pada 11 spesies famili Phyllanthaceae yang ditemukan di wilayah eksplorasi Kabupaten Banggai Kepulauan. Metode yang digunakan adalah pembuatan preparat paradermal dan transversal helai dan tangkai daun. Karakter yang diamati pada setiap preparat adalah karakter paradermal yaitu epidermis dan derivatnya, karakter transversal meliputi bentuk dan jumlah lapisan epidermis, mesofil, keberadaan kristal dan karakter khusus spesies serta bentuk berkas pengangkut pada tulang daun dan tangkai daun. Berdasarkan preparat paradermal daun diperoleh tipe daun hipostomatik dengan tipe stomata umumnya parasitik dan anomositik, dan ditemukan variasi tipe stomata anisositik pada Baccaurea nanihua dan Antidesma excavatum. Pada preparat transversal diperoleh tipe daun dorsiventral, bentuk epidermis dan jaringan tiang yang beragam. Pada organ tangkai daun, ditemukan empat tipe berkas pengangkut, yaitu bentuk lonjong dengan dua tambahan berkas pengangkut, bentuk dasar menyerupai ginjal, bentuk semi-lunar, dan bentuk lonjong dengan satu berkas pengangkut. Abstract Morphological characters are commonly used as a tool for plant identification. Anatomical characters can also be used as additional characters to provide strong descriptions of morphological characters and to resolve unclear identification of morphological characters. This study aims to identify leaf anatomical characters of 11 species of Phyllanthaceae family collected from the Banggai Kepulauan Regency. The characters are observed in each slide were paradermal characters, namely epidermis and its derivatives; transverse characters including the shape and number of epidermal layers, mesophyll, presence of crystals and species-specific characters as well as the shape of the vascular bundle on the midrib and petiole. The observation on paradermal section of lamina showed that all species have hypostomatic leaf, parasitic and anomocytic stomata types with variation of the anisocytic types were found in Baccaurea nanihua and Antidesma excavatum.Observation of the transverse section showed dorsiventral leaf types, size variation of upper epidermal cells as well as variations of palisade cells. The observation on transverse section of the petiole showed four types of vascular bundles in the petiole: oval shape along with two small separated vascular, the kidney – like shape, the semi-lunar shape and oval single vascular bundle.

Banana cropping patterns applied by farmers in West Java using polyculture systems. This system can build a diversity of plant species that are mutually beneficial. This study aims to determine the level of biodiversity of the banana ecosystem in West Java using vegetation analysis. The study was conducted in six districts in the area of West Java (Garut, Purwakarta, Bandung, Cianjur, Bogor and Banjar) from February to April 2019. The materials used were all types of plants found in each observation location, while the tools used in the study this is the Global Positioning System (GPS), long meter, short meter, handcounter, digital camera, stationery. Observations using survey and exploration methods and location determination are done by purposive sampling. Vegetation analysis results show that West Java has a high level of biodiversity in annual crops and annual plants with diversity index values of 2.66 and 2.83, respectively. Cassava (Manihot esculenta L.) became the most dominant annual crop in all plains with an important value index (INP) in the lowlands 86.62%, medium plains 58.32%, and in the highlands 57.22%. In the annual plants the dominant plants were coconut (Cocos nucifera) in the lowlands (INP = 42.31%), teak (Tectona grandis) in the medium data (INP = 35.79%) and mindi (Melia azedarach) in the highlands (INP = 54.28%).
