Bulbophyllum carunculatum also called as The Caruncule Bulbophyllum, Bulbophyllum amplebrateatum subsp carunculatum, is a species of the genus Bulbophyllum. This species was described by Garay, Hamer & Siegerist in 1995.
IDENTIFY BULBOPHYLLUM CARUNCULATUM
Bulbophyllum carunculatum is native to Sulawesi. They are found in primary and remnant forests at elevations of 800 to 900 meters.
It is a medium sized, warm growing epiphyte, which reaching up to 45 cm in height, with ovoid, up to 6 cm long pseudobulbs carrying a single, apical, distinctly petiolate, elliptic to obtuse, up to 36 cm long and 7 cm wide leaf.
The Caruncule Bulbophyllum blooms in the summer on an erect, 45 cm long, successively 12 flowering inflorescence with several tubular bracts and carrying fragrant flowers. The flowers are golden-yellow with a dark purple lip, which sometimes seems almost black. The dorsal petal is obovate-shaped, it is sharp-edged, up to 4 cm long and 1.5 cm wide. The lateral outer petals have a sickle shape, up to 5 cm long and 1.5 cm wide. The inner whorl flakes are ovate, pointed, and about 2.5 cm long and 1.2 cm wide. The lip is fleshy and has a papillary texture. It is about 2.5 cm long, is 3-bay, and the side plots are short and serrated. The straight rod is about 0.7 cm long and a pair of forward arms.
BULBOPHYLLUM CARUNCULATUM CARE AND CULTURE
Cultural information should only be used as a guide, and should be to be adapted to suit you. Your physical location; where you grow your plants, how much time you have to devote to their care, and many other factors, will need to be taken into account. Only then can you decide on the cultural methods that best suit you and your plants.
Light:
Bulbophyllum carunculatum needs a light level of 18000-30000 lux. Dappled shade or partial shade is recommended.
Temperature:
It is a thermophilic plant. It require warm temperatures from 21-27°C but will be comfortable in a temperature range of 7 to 35°C. They will not tolerate frosts. They need a temperature drop of about 6-8°C at night for flowering.
Humidity:
The Caruncule Bulbophyllum needs the humidity of around 80% throughout the year.
Substrate, growing media and repotting:
Bulbophyllum carunculatum are usually planted into very flat pots or baskets and apply a very loose, quickly drying ground. Different amounts of humectant additives, such as perlite or pieces of peat moss, can be mixed with a basic material consisting of small to medium sized pieces of pine bark or tree fern. The woody fern fibers are especially recommended because they do not decompose as quickly as pieces of pine bark, which means that it is not necessary to repot too often.
They do not like the violation of the roots and sometimes they get sick for up to one year or more to separate pseudobulbs or repotting. If the substrate has not decomposed but the plant has grown out of the container, you can transfer the plant with the entire root ball to a larger container without disturbing the roots. If repotting is necessary, make sure that new roots are already beginning to grow. This allows the plant to rooting as quickly as possible. Plants should, however, be repotted immediately after finding out that the substrate has decomposed.
Watering:
Bulbophyllum carunculatum should be abundantly watered during active growth, with slight drying between waterings. However, do not allow the substrate to become stale or soaked.
Fertilizer:
During the active growth, the plants should be fertilized every week 1/4-1/2 of the recommended dose of fertilizer for orchids. From spring to mid-summer, you can use fertilizer enriched with nitrogen, then switching to phosphorus-enriched fertilizer in late summer and autumn.
Rest period:
In winter, water should be slightly reduced, especially when the Bulbophyllum carunculatum is grown in the conditions of a short, dark day at moderate latitudes. This species, however, can not stay without water for too long. Fertilization should be eliminated until spring and until new growths appear.
