The Floral Morphology and Anatomy of Kenanga (Cananga odorata (Lam.) Hook.f. & Thomson)

Abstract

Cananga odorata (Lam.) Hook.f. & Thomson is one of the essential oils producing plants that have many benefits for humans. However, there is little information about the floral morphology and anatomy of C. odorata. The aim of this study is examining the floral morphology and anatomy of C. odorata. The flower morphology (color, shape, and size of the flower) were observed at fresh mature flowers. While, the flower anatomy (pistil, stamen, and ovary) were observed at flower histological samples. The flower was fixed, dehydrated, alcoholized, embedding in paraffin, and stained with safranin-fast green. The results of this study showed that flowers of C. odorata are complete flowers that had 3 green sepals (0.5 – 0.9 cm), 6 – 12 yellowish-green petals (2.5 – 7.2 cm), 8 – 15 dark green pistils (5 – 8 mm), and numerous stamens. The shape of pistils is oval and contains one ovary which has 8 – 12 ovules. The shape of the stamens is elongated oval and contains pollens. The information about the floral morphology and anatomy of C. odorata might enhance the understanding of future studies regarding natural reproduction and cultivation programs.

Study of Cananga odorata (Lam.) Hook. f. & Thoms. Flower Development: Morphological Variations in an Urban Environment

“…Numerous pointed stamens surround a group of separate pistils in the middle of the flower apex. This observation is consistent with the Cananga odorata flower morphology described by Parrotta and Nurhayani et al [1] [7].…”

“…Meanwhile, flowers in the mature stages of development contain compounds that contribute to the flowers' aromatic scents, such as hydrocarbon, esters, and alcohol compounds [3]. Previous studies have observed the anatomy and morphology of a few different stages in the Cananga odorata flower development [7]. Another study has also observed the volatile organic compound emissions of different Cananga odorata flower development stages [3].…”

Comparison of morphological characters, flowering phenology and essential oils of two accessions of Cananga (Cananga odorata var. fruticosa)

“…Cananga is a complete or perfect flower with petals, sepals, pistils, and stamens (Nurhayani et al 2019). The morphology of the two Cananga accessions observed showed differences in the leaf and stem characteristics, including leaf length, leaf width, petiole color, leaf's central vein color, and branch color.…”
