Abstract

Shrubs are commonly used as ornamental plants in the surrounding environment, yet studies on their anatomical characteristics particularly those of local species remain limited. This research examines the stem and leaf anatomy of three shrub species from different plant families: Nusa Indah (Rubiaceae), Hanjuang Merah (Asparagaceae), and Kembang Brokoli Kuning (Rutaceae). Using a qualitative descriptive method through histological observation, free‐hand sections were prepared for stem cross-sections and leaf paradermal slices. Observation parameters included stem tissue composition, epidermal cell form, stomatal type and distribution, and trichome characteristics. The results revealed distinct anatomical differences among the three families, which constitute the novelty of this study. Rubiaceae and Rutaceae showed open collateral vascular bundles, whereas Asparagaceae exhibited a concentric amphivasal type, a structural marker typical of monocots. Leaf epidermal cells also varied, with Rubiaceae showing wavy anticlinal walls, Asparagaceae presenting straight anticlinal walls, and Rutaceae having contrasting straight (adaxial) and wavy (abaxial) patterns. Stomatal distribution differed across species, with hypostomatic leaves in Rubiaceae and amphistomatic leaves in Asparagaceae and Rutaceae. Trichomes were found only in Rubiaceae, indicating a potential adaptive trait absent in the other families. These findings contribute to expanding anatomical references for local shrubs and provide comparative diagnostic characteristics useful for botanical identification and future anatomical studies of ornamental shrub species.

Abstract

Yellow Pumpkin (Cucurbita moschata) is a fruit and vegetable from the Cucurbitaceae family that has striking structural variations both microscopic and macroscopic. The study of the anatomical structure of the Yellow Pumpkin as a whole is still limited, so this study aims to study the anatomical structure of vegetative and generative organs in the species Cucurbita moschata. The research method is free-hand section for cross-sectional incisions of roots, stems, leaves, and paradermal leaves. Acetolysis method to obtain the morphological structure of flower pollen. This research is descriptive research. The parameters observed were in the form of organ constituent tissues, trichomes and stomata types, tracheal and fiber types, and pollen types. The results of the study showed that the root tissue was made up from the outside in, namely the epidermis, cortex, periticle, and vascular bundles (xylem and phloem). The trunk consists of trichoma-like epidermal tissue, cortex, xylem and phloem, as well as the trachea (spiral, annular and scalariform type) and libriform-type fibers. The leaf structure is composed of the epidermis above the polygonal shape and the lower form of the anticlinal sinuous, the anomocytic stomata type, the amphistomatic stomata distribution, and the leaf trichomes exist that are glandular and non-glandular. Pollen is spherical in shape, echinate-type exine, and is classified as pantoporate-type aperture. The results of this study can be used as basic data in the study of the anatomical structure of plants, especially cucurbitaceae.
