The subfamily Orchidoideae and the previously recognized subfamily Spiranthoideae are considered the closest allies in the natural group of the monandrous orchids because of several generally shared characters: a shared terrestrial habit; sectile (capable of being severed) or granular pollinia; erect anthers.
Orchid seeds are very small (0.35mm to 1.50mm long), spindle-shaped, and have an opening at the pointed end. [5] Each seed has an embryo that is undifferentiated and lacks root and shoot meristems. [3] An orchid seed does not have enough nutritional support to grow on its own, and lacks endosperm. [2]
Orchis is a genus in the orchid family (Orchidaceae), occurring mainly in Europe and Northwest Africa, and ranging as far as Tibet, Mongolia, and Xinjiang. [1] The name is from the Ancient Greek ὄρχις orchis , meaning "testicle", from the appearance of the paired subterranean tuberoids .
Coryanthes, commonly known as bucket orchids, is a genus of neotropical epiphytic orchids (family Orchidaceae). This genus is abbreviated as Crths in horticultural trade. They are native to South America , Central America , Mexico and Trinidad .
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.
Tulip orchids are rather large terrestrial and sometimes epiphytic plants with fleshy pseudobulbs longer than 20 cm. The long, lanceolate and plicate leaves of a full-grown Anguloa can be more than 1 m long. Two to four leaves grow from the base of each pseudobulb. The leaves are deciduous, and are shed at the start of each new growth ...
Orchis mascula is a perennial herbaceous plant with stems up to 50–60 centimetres (20–24 in) high, green at the base and purple on the apex. The root system consists of two tubers, rounded or ellipsoid. The leaves, grouped at the base of the stem, are oblong-lanceolate, pale green, sometimes with brownish-purple speckles.
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.
