What an orchid is
Orchids are plants of the family Orchidaceae, a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchid flowers have three sepals and three petals, and one petal is usually highly modified into a lip, or labellum. The labellum functions to attract insects and, in resupinate flowers, also acts as a landing stage, or sometimes a trap.
Cultivated orchids
Orchid species hybridize readily in cultivation, leading to a large number of hybrids with complex naming. Several thousand new cultivated orchid hybrids are registered each year. Phalaenopsis, also known as moth orchids, is a genus of about seventy species in the family Orchidaceae. Phalaenopsis orchids are among the most popular orchids sold as potted plants.
Floral markings
Nectar guides are markings or patterns seen in flowers of some angiosperm species that guide pollinators to their rewards. These markings may appear as lines, spots or blotches.
Orchid scent and pollination
Some orchids produce the aroma of nectar without providing the actual food reward. Others produce the aroma of female insects, attracting male insects to attempt to copulate. Methyl benzoate is one of many compounds that attract males of various species of orchid bees.
