 About Bulbphyllum
      Bulbophyllum is the largest genus in the orchid family Orchidaceae. With more than 2,000 species, it is also one of the largest genera of flowering plants, exceeded only by Astragalus. This genus is abbreviated in the trade journals as Bulb. It is round throughout most of the warmer parts of the world: Africa, southern Asia, Latin America, the West Indies, and various islands in the Indian and Pacific Oceans.

Growth of Orchids
      Epiphytes ; Growing on clinging to branches of trees. Roots orchids have thick roots covered with silver or white velamen.

Type of Growing for Bulbophyllum Orchids
      Bulbophyllum Orchid is Sympodial; Orchids are growing that grow sideways across the top of the pot. These orchids have a rhizome at the base usually put in horizontal, The bud at the base will begin growing anther rhizome. and then ,The rizome develops into a small plant or pseudobulb, and flower. When pseudobulbs have completely healthy, It will lose its leaves celled this pseudobulbs that "backbulb". It served store feed more years before it die.

Roots Bulbophyllum Orchid
      Semi-aerial roots : Usually found on the rocks or the trees. Roots can be absorbed many water. it smaller aerial roots. Most roots inside the pot. But may have some roots emerge outside the pot. This orchid roots not like a tight pots or wet for too long time, Which getting air not enough. This roots orchids such as Cattleya, Cymbidium, Dendrobium and Oncidium.

Culture
      Generally, Put it in warm temperatures, about 17-26'C. and use saran screen 50-60 percent. Keep moist in summer seasons [don't allow it dry]. Pot orchids in fine bark mounted or sphagnum moss.

Flowers.
  • Flower size about * cm.
  • Dorsal Sepal : *
  • Lateral Petal : *
  • Lateral Sepal : *
  • Lip : *

Leaves.
      Generally, Leaves of bulbophyllum orchid will emerge from the pseudobulb, 1-2 ea. Green color.

Watering Orchid
      Bulbophyllum like moisture place ,the plant should have a moisture content at all times. In summer should not leave orchid dry, Unless orchid could die. In rainy season, If orchids are wet, should not water the orchids, because maybe rot root.

Orchid Fertilizers.
      Before use the chemical fertilizer, should be water the orchids first, then use chemical fertilizer, because all genus of orchids can absorbed nutrients by roots and leaves. While it early is wet, Have a better absorbed chemical fertilizer than dry. Should be always use the chemical fertilizer may be a month at a time, or 2 times only.

Temperature and Light.
  • Temperature 17 to 26 'C.
  • Light should be about 50 to 60 percent.

Distribution
     Generally,

Pollination
      Many Bulbophyllum species have the typical odor of rotting carcasses, and the flies they attract assist in their reproduction through pollination.[3] Nevertheless, there are many species with mild and pleasant floral fragrance attract fruit flies (particularly Bactrocera spp.) via methyl eugenol, raspberry ketone or zingerone that also acts as floral reward during pollination.

      The erect to pendent inflorescence arises laterally from the base of the pseudobulb. The flower form has a basic structural blueprint that serves to identify this genus. But this form can be very diverse : compound or single, with few to many flowers, with the resupinate flowers arranged spirally or in two vertical ranks. The sepals and the petals can also be very varied : straight or turned down, without footstalk or with a long claw at the base. They are often hairy or callous. There are two to four hard and waxy pollinia with stipes present or absent. The fruits are beakless capsules.

Cultivation
      The fabulous and bizarre species that comprise this large genus have been the focus of orchid collectors for over a century. The plants require high humidity combined with good air movement and most of them are ever-blooming - flowering continuously throughout the year. They grow best at moderate light levels, but do not in deep shade. They are considered moderate to difficult in cultivation, and require a controlled growing environment to achieve some degree of success. They are not typically suitable as houseplants, and most will not thrive in a wardian case unless they receive adequate air movement.

      The plants' growth habit produces widely spaced pseudobulbs along cord-like rhizome sections, and most of these plants are best accommodated on plaques. Some species in this genus can get very large, but most are small to medium-sized epiphytes from warm, moist, humid tropical forests. They can grow continuously year round with no apparent dormancy period if they are kept warm, are moderate feeders in cultivation, and must be kept moist all the time. They can tolerate dryness for short periods, but they have fine root systems which require moist conditions all the time.[9]

      Some of the smaller species do well in pots with small-diameter bark substrate. The plants produce very fine roots generally, and the roots are easily damaged. The plants react poorly to disturbance of their roots. They are easy to maintain once a good environment is established with high humidity and a fresh, buoyant, lightly circulating atmosphere being critical. Most of these species cannot tolerate cold temperatures or freezing.[9]

      The flowers produce various odors resembling sap, urine, blood, dung, carrion, and, in some species, fragrant fruity aromas. Most are fly-pollinated, and attract hordes of flies. Bulbophyllum beccarii in bloom has been likened to smelling like a herd of dead elephants and both this species and Bulbophyllum fletcherianum are variously described as making it difficult to walk into a greenhouse in which they are being cultivated if the plants are in bloom because of their overpowering floral odors.[9]
