“…guineense data suggests self-compatibility, spatial separation of the stigma and stamens in this species could indicate a preference for cross-pollination, as has been suggested for other self-compatible Syzygium species [e.g. 38 ] since outcrossing may still be desirable and may produce superior offspring [e.g. 36 ].…”

“…The fruits are also sometimes utilised by people, and the bark and roots have medicinal properties [ 47 ]. Many studies have investigated reproductive aspects of other species within the more globally widespread and speciose Syzygium genus (~1200 species), finding predominantly at least partial self-compatibility but a range of reproductive strategies are employed within the genus including self-compatibility [ 32 – 34 , 38 ], partial self-compatibility [ 31 , 33 , 35 , 49 ], and self-incompatibility [ 50 , 51 ]. A variety of floral visitors and pollinators have been documented for species within the Syzygium genus, including birds, bats, and a variety of insects such as bees, flies, moths, butterflies, wasps, ants, and others (see S2 Table in S1 Appendix ).…”

Forest products derived from woody trees, such as fruits, seeds, honey, wood and others, are important resources for supporting rural livelihoods. However, little is known about the breeding systems or floral visitors of trees that provide these resources, often due to the difficulty of accessing tree canopies. This study addresses key knowledge gaps from a data poor region, providing information on the breeding systems and contribution of biotic pollination to two trees abundant in south-central Africa, that provide forest product supports for rural livelihoods: Julbernardia paniculata (Benth.) Troupin and Syzygium guineense (Willd.) subsp. barotsense F. White (Fabaceae and Myrtaceae respectively). The breeding systems of these species were assessed by conducting controlled pollination experiments, and then measuring the effects on reproductive success to determine the degree of self-compatibility and pollen limitation. Floral visitors and their behaviour were observed to provide preliminary information on possible pollinator groups. S. guineense appeared to be self-compatible, while J. paniculata showed signs of both self-incompatibility and pollen limitation. Floral visitors of both species were dominated by bees, with native honeybees (Apis mellifera) providing the highest visitation rates. These insights provide the first steps for understanding the reproductive ecology of these key tree species and can help to inform sustained management and conservation aimed at protecting forests and supporting rural livelihoods, as well as broaden the understanding of the floral visitors, and contribution of biotic pollination to forest tree reproductive success.

“…Syzygium guineense is one of the important species from the genus Syzygium . It is an evergreen flowering forest plant widely distributed in the tropical regions of Australia, Asia, and Africa [ 2 ]. This evergreen tree, belonging to the family Myrtaceae , is also distributed throughout sub-Saharan Africa and grows to a height of 12–15 m. This species is naturally found in Senegal, stretching to Somalia in the east and extending southward to South Africa.…”

“…The plant is known by different local names in Ethiopia such as “Dokma” in Amharic, “Badeessaa” in Oromifa, and “Duwancho” in Sidama [ 3 ]. The plant is known by different English names such as water-berry, water-boom, or water-pear [ 2 ]. The fruits are edible in various parts of sub-Saharan African countries including Ethiopia, particularly in rural areas and during droughts.…”

Abstract. Mudiana D, Ariyanti EE. 2021. Syzygium myrtifolium Walp. flowering stages and its visitor insects. Biodiversitas 22: 3489-3496. “Pucuk merah” or Red lip (Syzygium myrtifolium Walp.) is widely known as an ornamental plant used as garden components. This species belongs to the Myrtaceae family with the scientific name Syzygium myrtifolium Walp. This paper specifically aimed to observe the stages of flowering and visiting insects of S. myrtifolium, while the determination of insects as pollinators was not carried out in this study, and was intended merely to make a species list of visiting insects, without counting the number of individuals and the times of their visits. These are done by examining two individual trees of S. myrtifolium (which have flowered and fruited several times) during its flowering season, recording all visible flower developments and the visitor insects. The visitor insects were observed during flower bloom. The results showed ten stages of flowering process in S. myrtifolium starting from emerging flower buds until fruits riped, which took 105-124 days. Twelve species of insects were recorded visiting flowers of S. myrtifolium during full blooming period, namely Euploea core, Hypolimnas bolina, Telicota colon, Eurema hecabe, Rapala pheretima, Apis cerana, Apis mellifera, Trigona sp., Dysphania sagana, Amata trigonophora, Chrysomya megacephala, Lucilia caesar. They belong to three orders, i.e. Diptera, Hymenoptera and Lepidoptera; and eight families, namely Calliphoridae, Apidae, Hesperiidae, Nymphalidae, Lycaenidae, Geometridae, Erebidae, and Pieridae.
