“…Floral biology ranges from the flowers’ emergence, form, and function to advertisements and rewards concerning pollination (Gottsberger 1989 ; Willmer 2011 ). Pollination has been studied in some endoparasites, and due to their peculiar morphologies, the study of the form and function of the flowers has become important to understand aspects of the reproductive biology of the species (Bänziger 1991 ; Beaman et al 1988 ; De Vega et al 2009 ; García-Franco and Rico-Gray 1997 ; Hobbhahn and Johnson 2015 ; Johnson et al 2011 ; Sipes et al 2014 ; Suetsugu 2019 ).…”

Bdallophytum americanum (Cytinaceae) is an endoparasitic plant species, meaning only the flowers emerge from the host during the reproductive season. Reports on the pollination biology of this species state that its primary pollinators are carrion flies attracted by the smell of the flowers and nectar as a reward. However, the functional role of one of the most outstanding attributes of B. americanum has been neglected. These are the staminal appendages formed by the apical overgrowth of connective tissue during anther development. To determine whether these staminal appendages play a role in pollination, we monitored a nectarless population of B. americanum. We described the inflorescence emergence, floral movements, and pollination and performed field experiments to test whether the absence of the staminal connective appendages affected the visitation frequency. Male inflorescences emerge early, and both male and female flowers open during the day and do not close. Hoverflies are the most frequent visitors to both floral sexes and carry the most pollen. Moreover, the movement of staminal appendages matching the pollen viability changes is reported for the first time. The staminal appendages are the structures where pollinators land before foraging. The field experiments showed that the visitation frequency decreased sharply without staminal appendages. As a landing platform, the staminal connective appendages in B. americanum are crucial for pollinator positioning and collecting viable pollen.

“…The floral characteristics, such as small size, pinkish white papilionaceous corolla with explosive pollen release mechanism, and zygomorphic symmetry, indicate that the plant has specialized pollination mechanism adapted for tripping by external agents. Such an explosive pollination mechanism has also been reported in the allied species, Pongamia pinnata (Solomon Raju and Rao, 2006), other Fabaceae members (Meeuse, 1961), and also in other plant families such as Lamiaceae (Solomon Raju, 1990), Loranthaceae (Feehan, 1985), Onagraceae (Plitmann et al, 1973), Rhizophoraceae (Davey, 1975;Tomlinson, et al, 1979), Marantaceae (Davis, 1987), Urticaceae (Taylor, 1942), Ericaceae (Marie-Victorin, 1942), Fumariaceae, Musaceae, Acanthaceae (Proctor and Yeo, 1972), Cornaceae (Mosquin, 1985), and Orchidaceae (Proctor and Yeo, 1972;Gottsberger, 1989).…”

Floral biology, sexual system, breeding system, pollinators, fruiting and seed dispersal aspects of five mangrove associate species, namely, Clerodendrum inerme, Derris trifoliata, Suaeda maritima, S. monoica, and S. nudiflora were studied. All these species are hermaphroditic, self-compatible, and exhibit mixed breeding systems adapted for pollination by external agents. C. inerme and D. trifoliata are principally entomophilous, while Suaeda species are ambophilous. The study suggests that these plant species are important constituents of mangrove forests. C. inerme and D. trifoliata are useful in stabilizing the banks of back water creeks, while Suaeda species are useful to carpet the saline areas and desalinate the soils which are subsequently useful for agricultural activities. Articolul prezintă studiul asupra biologiei florale, sistemului sexual, sistemului de creștere, polenizatorilor, rodirii și răspândirii semințelor la cinci specii de mangrove asociate, Clerodendrum inerme, Derris trifoliata, Suaeda maritima, S. monoica și S. nudiflora. Toate aceste specii sunt hermafrodite, auto compatibile și prezintă sisteme de creștere mixte adaptate pentru polenizare de către agenții externi. C. inerme și D. trifoliata sunt în principal entomofile în timp ce speciile Suaeda sunt ambophilous. Studiul sugerează că aceste specii de plante sunt constituenți importanți ai pădurilor de mangrove. C. inerme și D. trifoliata sunt utile în stabilizarea malurilor cursurilor de apă, în timp ce speciile Suaeda sunt utile pentru covorul zonelor saline și desalinizarea solurilor care sunt ulterior utile pentru activități agricole. ZUSAMMENFASSUNG: J. S. R. Aluri et al. -Reproductive biology of mangrove plants (31 ~ 68) 32 INTRODUCTIONMangrove conservation has received an increased importance in the recent past as research has increased the understanding of the values, functions, and attributes of mangrove ecosystems and the role they play in providing important ecological services and livelihoods for the mangrove associated communities. Mangrove forests are among one of the world's most productive tropical ecosystems. They are now one of the most threatened ecosystems in the world due to natural and demographic pressures (Roy and Krishnan, 2005). The mangrove vegetation is comprised of unique plant communities consisting of evergreen trees and shrubs belonging to several unrelated families growing in tropical and subtropical intertidal regions where there is constant intertidal exchange of sea water and freshwater (Spalding et al., 1997).The focus of research on the reproductive biology of mangrove plants has almost exclusively been on the fruit and seed or seedling dispersal stage. Surprisingly, less is known about floral biology, pollination, and breeding systems, although knowledge of the effectiveness of floral mechanics and genetic isolating mechanisms is an important prerequisite to the study of successful dispersal and establishment (Primack et al., 1981;Tomlinson, 1986;Juncosa and Tomlinson, 1987;Clarke and Meye...
