![]() ![]() chani carrion flies to the flowers.Ĭalliphoridae Carrion flower Carrion-mimicry Chrysomya chani Oligosulfides Rafflesia cantleyi Rafflesiaceae Sapromyiophilous syndrome.Ĭopyright © 2018 Elsevier Ltd. cantleyi biochemically mimics carrion and that relative ratio of oligosulfides in the floral scent play a key role in sex-biased pollinator specialization, attracting only female C. chani flies to individual DMDS, DMTS, and a blend of DMDS and DMTS was evident. In flight-tunnel bioassays, a female-specific positive response of C. These were accompanied by other minor compounds such as benzenoids (4), monoterpenoids (4), trace amounts of aliphatic compounds (1), and sesquiterpenes (1). The floral volatiles emitted by male flowers in full bloom were dominated by two sulphur-containing compounds, dimethyl disulfide (DMDS) and dimethyl trisulfide (DMTS). cantleyi pollen after visiting male flowers. Smilax herbacea, a native American woodland vine, has malodorous flowers and is also called carrion flower. However, only flower visitors of one blow fly species, Chrysomya chani Kurahashi, were observed to carry R. Five species of calliphorid flies (subfamilies of Chrysomyinae and Calliphorinae), all females, were found on the flowers, whereas nine species were found in the traps that were baited with tainted meat in the surrounding habitat. In addition, flower-visiting calliphorid flies and the local carrion fly community were sampled and identified. The olfactory preferences of pollinators to the identified chemical compounds, were tested singly and in blends, in flight tunnel bioassays and compared with responses to headspace floral extracts. To achieve these aims, the floral scent was collected in situ in the field using a dynamic headspace method followed by chemical analysis via GC-MS. cantleyi Solms-Laubach and their role in pollinator attraction. In the present paper, we studied the floral volatiles of R. However, information on the pollination biology of this plant group remains limited and mostly anecdotal. If using as a container plant near the house, nip off the flowers when they become pungent.The plants of the enigmatic genus Rafflesia are well known for their gigantic flowers and their floral features such as pungent floral scent and vivid dark color, which mimics the food/brood sites of carrion. Uses Landscaping:Įxcellent and hardy addition to a rocky outcrop garden or rockery, or even used as a container plant for textural effect. The pungent smelling flowers attract fly pollinators. As with all Carrion Flowers, they smell foul in order to. Plant in sun or semi-shade in rich, porous, well-drained soil and water sparingly. Clusters of large, bell-shaped, reddish to dark-purple flowers are borne from November to January. Carrion flower is a leafless, perennial herb with fleshy stems. The flowers attract flies as pollinators. ![]() Its other common name Carrion Flower comes from the fact that the flower has the odor of rotting meat. Shallow containers are most suitable for planting these succulents in. Description Starfish Plant is a succulent plant with very large star-fish looking flowers in the dog bane family. The seedpods that follow resemble paired horns.Īn excellent succulent for a sunny rockery, but also makes an unusual container plant. As with all Carrion Flowers, they smell foul in order to attract their pollinators. Clusters of large, bell-shaped, reddish to dark-purple flowers are borne from November to January. The upright, fleshy, prominently-angled, dark-green stems have sharply-pointed teeth on the margins. Stapelia leendertziae is a very hardy, evergreen, drought-resistant, sprawling succulent. ![]()
