“…There are other means by which the floral chamber is secluded in Araceae where, in Cryptocoryneae an extension of the spathe margin occludes the floral chamber, while in Areae a twist of the spathe causes closure of the constriction between the floral chamber and the blade (Bröderbauer et al . ). However, in A. nicolsonii , access to the lower chamber remained and the fruits are developed in an open splash‐cup (Wong ).…”

Floral diversity and pollination strategies of three rheophytic Schismatoglottideae (Araceae)

et al. 2015

Homoplastic evolution of 'unique' morphological characteristics in the Schismatoglottideae -many previously used to define genera -prompted this study to compare morphology and function in connection with pollination biology for Aridarum nicolsonii, Phymatarum borneense and Schottarum sarikeense. Aridarum nicolsonii and P. borneense extrude pollen through a pair of horned thecae while S. sarikeense sheds pollen through a pair of pores on the thecae. Floral traits of spathe constriction, presence and movement of sterile structures on the spadix, the comparable role of horned thecae and thecae pores, the presence of stamen-associated calcium oxalate packages, and the timing of odour emission are discussed in the context of their roles in pollinator management. Pollinators for all investigated species were determined to be species of Colocasiomyia (Diptera: Drosophilidae).

“…a congenitally united calyx to form the trapping chamber. In contrast, Ceropegia achieves the same structure by congenital fusion and basal inflation of the corolla (Ollerton et al, 2009), while the genus Arum and related plants forgo floral tissues altogether and enclose their male and female florets within a highly modified bract (Bröderbauer et al, 2012;Meeuse and Raskin, 1988). As recognized by Vogel (1990), whose treatise on osmophores featured many examples from these lineages, floral scent can be highly chemically diverse among Ceropegia, Arum, Amorphophallus and other aroid lineages, including chemically mediated mimicry of carrion, herbivore and carnivore feces and rotting fruit/yeast (Kite et al, 1998;Stökl et al, 2010;Urru et al, 2011).…”

Adaptations for insect‐trapping in brood‐site pollinated Colocasia (Araceae)

2013

The Araceae include both taxa with rewarding and deceptive trap pollination systems. Here we report on a genus in which rewarding and imprisonment of the pollinators co-occur. We studied the pollination of four species of Colocasia in Southwest China and investigated the morpho-anatomical adaptations of the spathe related to the attraction and capture of pollinators. All four species were pollinated by drosophilid flies of the genus Colocasiomyia. The flies are temporally arrested within the inflorescence and departure is only possible after pollen release. Trapping of the flies is accomplished by the closure of the spathe during anthesis. Moreover, in two species the spathe is covered with papillate epidermal cells known to form slippery surfaces in deceptive traps of Araceae. However, in Colocasia the papillae proved not slippery for the flies. The morpho-anatomical properties of the spathe epidermis indicate that it is an elaborate osmophore and serves for the emission of odours only. Despite its similarity to deceptive traps of other aroids, Colocasia and Colocasiomyia have a close symbiotic relationship, as the attracted flies use the inflorescence as a site for mating and breeding. The trap mechanism has presumably evolved independently in Colocasia and is supposed to facilitate more efficient pollen export.
