Abstract

Kirinyuh (Chromolaena odorata L.) is a shrub that belongs to the Asteraceae family and is classified as a dicotyledonous plant. Each plant has characteristics that are generally different, such as stomata and trichomes owned by kirinyuh leaves. This study aims to analyze the characteristics of stomata and trichomes of kirinyuh leaves, examine the structure of kirinyuh leaf layers based on transverse sections, and calculate the density of stomata and trichomes in paradermal sections of kirinyuh leaves. This study used a laboratory experimental method by making simple microscopic section preparations. This study was conducted at the Laboratory of the Faculty of Educational Sciences, Syarif Hidayatullah State Islamic University, Jakarta. Samples were obtained from Ciomas Permai Housing, Ciapus Village, Ciomas District, Bogor Regency. The results of this study show that paradermal sections on the adaxial cross-section, kirinyuh leaves have irregular epidermis with anomocytic oval type stomata with kidney-like guard cells and non-glandular type trichomes with multicellular uniseriate type. The stomata found were 115 with a density of 8.38 stomata/mm2 and an index of 0.056 mm2, while the trichomes found were 3 with a density of 0.21 trichomes/mm2. In the transverse section, the layers of kirinyuh leaves are composed of upper epidermis tissue, palisade tissue, blood vessel bundles, sponges, lower epidermis, and trichomes.

Abstract

The Bogor Botanical Gardens' Mexican Park presents various dry-climate plants useful for recreation and learning. The presence of weeds in the collection site would have a negative impact because they can inhibit the growth of the collection plants. This study examined the diversity of weeds in the Mexican Park, Bogor Botanical Gardens. This descriptive study took place in the Bogor Botanical Gardens, specifically in the Mexican Park, and weed identification was carried out at the National Research and Innovation Agency. The weed data obtained was then analyzed descriptively through a literature study. The results showed that there were 52 weed species from 28 families. Most species came from the Asteraceae and Araceae families. The block that had the most weeds was Block II.O.IV, with a total of 15 weed species. The species that were often found in each area of the Mexican Garden Collection include Euphorbia graminea Jacq., Euphorbia heterophylla L., Calliandra calothyrsusMeisn, Coleus monostachyus (P. Beauv.) AJ Paton, Cecropia peltate L., and Cissus verticillata subsp. verticillata. Keywords: Inventory, Weeds, Mexican Park, Bogor Botanical Garden
