Bees outpace orchids in evolution

(PhysOrg.com) -- Orchid bees aren’t so dependent on orchids after all, according to a new study that challenges the prevailing view of how plants and their insect pollinators evolve together.

The evolution of orchids

(PhysOrg.com) -- Charles Darwin and many other scientists have long been puzzled by the evolution of orchids, the largest and most diverse family of flowering plants on Earth. Now genetic sequencing is giving scientists insights ...

Tiny orchid flowers pollinated by tiny flies

Researchers Yuta Sunakawa, Ko Mochizuki, and Atsushi Kawakita of the University of Tokyo have discovered the first orchid species pollinated by gall midges, a tiny fly species. This is the first documented case of an orchid ...

Fungi-eating plants and flies team up for reproduction

Fungi-eating orchids were found for the first time to offer their flowers to fungi-eating fruit flies in exchange for pollination, which is the first evidence for nursery pollination in orchids. This unique new plant-animal ...

Orchidaceae

The Orchidaceae, commonly referred to as the orchid family, is a morphologically diverse and widespread family of monocots in the order Asparagales. Along with the Asteraceae, it is one of the two largest families of flowering plants, with between 21,950 and 26,049 currently accepted species, found in 880 genera. Selecting which of the two families is larger remains elusive because of the difficulties associated with putting hard species numbers on such enormous groups. Regardless, the number of orchid species equals more than twice the number of bird species, and about four times the number of mammal species. It also encompasses about 6–11% of all seed plants. The largest genera are Bulbophyllum (2,000 species), Epidendrum (1,500 species), Dendrobium (1,400 species) and Pleurothallis (1,000 species).

The family also includes Vanilla (the genus of the vanilla plant), Orchis (type genus), and many commonly cultivated plants such as Phalaenopsis and Cattleya. Moreover, since the introduction of tropical species in the 19th century, horticulturists have produced more than 100,000 hybrids and cultivars.
