Bulbophyllum fenestratum is a species of orchid in the section Cirrhopetalum that is native to Southeast Asia. The specific epithet fenestratum derives from the Latin fenestra, meaning "window".[3]
Description
Bulbophyllum fenestratum is a small epiphyte with a creeping rhizome giving rise to ovoid to ellipsoid, distinctly four-angled pseudobulbs spaced 2–16 cm apart.[4] Each pseudobulb bears a single apical, erect, obovate to egg-shaped leaf with an obtuse to acute tip and a petiolate base.[4]
The inflorescence is erect to spreading, arising from the base of the pseudobulb on a peduncle 8–12 cm long with a porrect to curved rachis, reaching 9–13 cm in total length.[4] The inflorescence is subumbellate, bearing 7 to 15 flowers arranged in an umbrella-like cluster characteristic of the Cirrhopetalum section.[4][5] Individual flowers are approximately 1 cm long, white densely punctuated with pink, and borne on pedicels of similar length.[3][6] The flowers are fragrant and possess a mobile lip, a characteristic feature of the genus Bulbophyllum.[7]
Taxonomy
Bulbophyllum fenestratum was first formally described in 1907 by Johannes Jacobus Smith in the Bulletin du Département de l'Agriculture aux Indes Néerlandaises from specimens collected in Java.[2][3] The species is placed in Bulbophyllum section Cirrhopetalum, a group characterized by umbellate inflorescences and lateral sepals that are longer than the dorsal sepal.[5]
Several names are now considered synonyms of this species, including Bulbophyllum dentiferum described by Henry Nicholas Ridley in 1915 and Bulbophyllum cyclosepalon described by Cedric Errol Carr in 1932.[2]
Distribution and habitat
Bulbophyllum fenestratum is found in Thailand, Peninsular Malaysia, Sumatra, Java, and Borneo.[2][4] It grows as an epiphyte in rather open, dry primary forests at elevations between 100 and 1,100 metres.[4]
Cultivation
In cultivation, Bulbophyllum fenestratum is described as an easy-growing species tolerant of a range of temperatures from hot to cool conditions.[4][7] Like most members of the genus Bulbophyllum, it requires high humidity combined with good air movement and grows best at moderate light levels.[8] The species is considered cold-tolerant relative to other members of its section.[7]
