Bulbophyllum longiflorum, commonly known as the pale umbrella orchid, [2] is a species of epiphytic or lithophytic orchid. It has a creeping rhizome , widely spaced, dark green pseudobulbs with a single large, fleshy leaf, and flowers spreading in a semicircular umbel , resembling one-half of an umbrella.
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.
The Orchidoideae, or the orchidoid orchids, are a subfamily of the orchid family (Orchidaceae) that contains around 3630 species. [1] Species typically have a single ( monandrous ), fertile anther which is erect and basitonic .
The orchid family is one of the largest flowering plant families in the world. Orchids can be found on every continent except Antarctica, from the steamy jungles of Asia to the dry deserts of ...
Bulbophyllum exiguum is a small, epiphytic or lithophytic orchid with small, roughly spherical pseudobulbs, usually 5 to 10 mm in length which taper towards the leaf. Each pseudobulb carries one leaf, about 25 to 30 mm long but greatly variable. The flowers are small and creamy white to yellow, and have sepals roughly twice as long as the petals.
The world's richest diversity of orchid genera and species is found in the tropics. Orchidaceae is one of the two largest families of flowering plants, along with the Asteraceae. It contains about 28,000 currently accepted species distributed across 763 genera. [3] [4] The Orchidaceae family encompasses about 6–11% of all species of seed ...
In the 1990s, orchid taxonomy began to be influenced by molecular phylogenetics based on DNA sequences. The first molecular phylogenetic study to include a substantial sample of orchids was published in 1999. [12] The first classification that was based on cladistic analysis of DNA data was published by Chase et alii in 2003. [13]
The labellum is an elongated heart shape, 4–5 mm (0.16–0.20 in) long, 2–3 mm (0.08–0.1 in) wide, bluish-purple with a white tip and with a furrow near its base. At the base of the labellum there are two large, club-shaped calli joined at their bases, each with a fleshy black top. Flowering occurs from July to October, more prolifically ...
