Propagation
Divide when new roots appear or when the plant looks weary. Cut off two healthy pseudo bulbs and place them in the centre of the pot with enough room for two years growth. 

Sterilise fresh seeds and sow during spring in a sterile nutrient rich mix. 

The seeds must be supported with a fungus until they germinate (this may be available on top of existing pots of orchids) 

Note:
These plants require, 70% humidity and a temperature range of 19º to 27º C (66º to 81º F) and during winter watering should be reduced.

Botanic information
Leaf: The bifoliate types have only 2-lanceolate leaves from each pseudobulb. They are fleshy and green to yellowish.
The unifoliate types have 1-large leathery broad lanceolate leaf per psudobulb.

Flower: The labiate flowers of both groups have 3-sepals, 2-petals and the large lip (labellum) that is tube-like at the base and flares out with wavy margins. There is a wide range of colours available and they normally last for 1 to 2 weeks. The flowering period varies depending on species but generally appear during summer.  

Fruit: They have a single chambered capsular fruit that contains many small seed with no endosperm. The small seeds are viable but the plant is commonly reproduced vegetatively, to maintain true to type. 

Culture
Temperature: 
This plant requires 24º - 29º C. during day light and 21º -24º C. during night. 
Temperature variation that is high will cause burning and too low will cause blotches and disfigured growth.
Humidity should be 50 -60%. (Mist during hot weather).

Ventilation: 
Best results with fresh circulating air (reduces disease).

Light requirements: 
Tolerates 30 - 70% of full sun, either with natural shading or the use of shade cloth.

Growing media: 
Epiphytic orchids can be grown on pieces of tree fern trunk or firm bark that must be kept moist. 
If grown in pots the mix should contain, pine bark, charcoal, sphagnum moss, course washed sand.
 
Pests and Diseases:
Orchids suffer from, aphids, mealy bugs, snails and slugs, loopers and rot.
2-spotted mite, causes silvering and death of the leaves.
Scale both soft and hard.
Rot of pseudo bulbs, (cut away damaged parts and apply fungicide).
Fungal leaf spots, cause brown and sunken patches on the leaves.
Virus, ring spot or cymbidium virus (destroy plants and apply insect control).
