Bulbophyllum medusae, commonly known as the Medusa orchid, is a species of epiphytic orchid with a creeping rhizome and a single leaf about 100 mm (3.9 in) long emerging from the top of each pseudobulb. The flowers are creamy yellow and arranged in clusters of about fifteen arranged in a circle at the tip of the flowering stem.
Bulbophyllum is a genus of mostly epiphytic and lithophytic orchids in the family Orchidaceae. It is the largest genus in the orchid family and one of the largest genera of flowering plants with more than 2,000 species, exceeded in number only by Astragalus.
Diuris carinata is a tuberous, perennial herb with between four and six erect leaves 100–200 mm (4–8 in) long and 3–6 mm (0.1–0.2 in) wide. Between two and seven bright yellow flowers with reddish brown markings, about 30 mm (1 in) long and 20–30 mm (0.8–1 in) wide are borne on a flowering stem 500–800 mm (20–30 in) tall.
Arethusa bulbosa, commonly called dragon's mouth orchid, [4] is the only species in the orchid genus Arethusa. [3] The genus is named after a naiad of Greek mythology . [ 5 ] This monotypic genus is abbreviated Aret in trade journals.
Orchids in the genus Diuris are terrestrial, perennial, deciduous, sympodial herbs, usually with a few inconspicuous, fine roots and one or two tubers lacking a protective sheath. The stem is short, erect and unbranched with a leaf-like cataphyll at each node. There are between one and ten grass-like leaves at the base of the plant. [3] [4] [5] [6]
Bucket orchids are an excellent example of coevolution and mutualism, as the orchids have evolved along with orchid bees (the tribe Euglossini of the family Apidae) and both depend on each other for reproduction. [2] One to three flowers are borne on a pendant stem that comes from the base of the pseudobulbs.
Researchers from Poland and Colombia recently discovered a new orchid species with a rather attention-getting feature. At its heart is a formation that bears a striking resemblance to a devil.
In botany, a pseudobulb is a storage organ found in many epiphytic and terrestrial sympodial orchids. It is derived from a thickening of the part of a stem between leaf nodes and may be composed of just one internode or several, termed heteroblastic and homoblastic respectively. All leaves and inflorescences usually arise from this structure.
