“…14 species out of them were carrying one or more pollinaria of G. diphylla and were seen visiting several flowers. They were classified as pollinator (Schatz et al, 2005;Henneresse & Tyteca, 2016). During daylight we never observed any insects visiting or pollinating Gennaria diphylla.…”

“…The Madeiran site was located near Faial,32°47'26.4768''N and 16°51'42.804 Insects carrying, removing and/or depositing pollinaria, visiting several flowers and actively probing the spurs of the orchids were classified as pollinators. Insects sitting on the inflorescence and showing interest in the flower but not probing the flower and carrying no pollinaria were classified as visitors, as proposed by Schatz et al (2005) and Henneresse & Tyteca (2016).…”

Pollination strategy of Gennaria diphylla (Orchidaceae) on the Canary Islands and on Madeira

et al. 2022

Gennaria diphylla (Link) Parl. is a terrestrial, inconspicuous green orchid. Its distribution includes the central and western Mediterranean region as well as the Canary Islands and Madeira. Investigations on its pollination biology are scarce. In literature there are mentions of autogamy and of allogamy. Pollination and pollen import and export were studied on Tenerife and Madeira. The investigations showed autogamy plays a less important role than thought, although a caging experiment showed that the species is well capable of self-pollination. The orchid is pollinated by a variety of small moths, especially of the families Geometridae, Pyralidae and Crambidae. It is flowering in a period when few other plants flower, so there is little competition for pollinators. Complemented by autogamy this seems to be a successful strategy, as the species shows a relatively high average fruit set of 73 %.

“…Myophily (pollination by flies that feed on nectar and pollen as adults), Sapromyophily (pollination by flies that normally visit dead animals or dung for breeding), Cantharophily (pollination by beetles), Malacophily (pollination by slugs and snails), Ornithophily (pollination by birds), Chiropterophily (pollination by bats). In order to reproduce, most orchid species depend on biotic pollen vectors (Henneresse and Tyteca, 2016). Orchids attract their pollinators either by rewarding them or by deceiving (non-rewarding) them.…”

Aesthetically, economically and ecologically significant flowering plant group orchids use several types of pollination strategy for reproductive success. Specially cross-pollinated orchids lure huge number of diverse pollinators by utilizing unique and spectacular deceptive pollination mechanism alongside rewarding mechanism. 1350 reported Indian species distributed across the whole continent and found mainly in the Eastern Himalayas and North Eastern, North West Himalayas, Peninsular India, and Andaman and Nicobar Islands. There are plethora of India based researches on geographical distribution, conservation and diversity, morphology and taxonomy, cultivation and artificial propagation and also economical uses of orchids. But there is significantly lesser amount of reports present especially in Indian perspective about orchid pollination studies. Here we discuss about orchids and their pollinators along with different pollination mechanisms by assembling several available scientific data, photographs, analyses, comparisons, facts etc. reported till to date. Discussions in this review represent a quality overview on current state of orchid pollination specially mentioning about Indian orchid species, their distribution and their pollinators. This study may be useful and beneficial for the future researchers who are willing to work on orchid pollination biology with a special emphasis on India.

“…The four studied orchid species are pollinated by generalist pollinators such as bees and bumblebees that are attracted to the flowers by their color or form, but quickly learn to avoid them as they do not provide any reward [27]. For example, the flowers of O. militaris have been shown to be visited by at least 49 different insect species, including hoverflies, bumblebees and bee flies [60]. However, most of these insects probably did not function as an effective pollinator, and pollinia were only observed in two species (Apis mellifera and Bombus lapidarius).…”

Impact of Climate Change on the Distribution of Four Closely Related Orchis (Orchidaceae) Species

2020

Long-term monitoring programs and population demographic models have shown that the population dynamics of orchids are to a large extent dependent on prevailing weather conditions, suggesting that the changes in climatic conditions can have far reaching effects on the population dynamics and hence the distribution of orchids. Although a better understanding of the effects of climate change on the distribution of plants has become increasingly important during the final years, only a few studies have investigated the effects of changing temperature and precipitation on the distribution of orchids. In this study, we investigated the impact of climate change on the distribution of four terrestrial orchid species (Orchis anthropophora, Orchis militaris, Orchis purpurea and Orchis simia). Using bioclimatic data for current and future climate scenarios, habitat suitability, range shifts and the impact of different abiotic factors on the range of each species were modelled using Maxent. The results revealed an increase in suitable habitat area for O. anthropophora, O. purpurea and O. simia under each RCP (Representative Concentration Pathway) scenario, while a decrease was observed for O. militaris. Furthermore, all four of the orchids showed a shift to higher latitudes under the three RCPs leading to a significant range extension under mild climate change. Under severe climate change, a significant decline in the distribution area at the warm edge of their distributions was observed. Overall, these results show that mild climate change may be beneficial for the studied orchid species and lead to range expansion. However, continued warming may yet prove detrimental, as all species also showed pronounced declines at lower latitudes when temperature increases were larger than 4 °C.
