The Veined Oncidium is native to Brazil, Bolivia and Paraguay (in the states of Goias, Bahia, Minas Gerais, Sao Paulo, and Parana). They usually grow in sunny positions in semi-tropical forests at heights of 600-800 m, but their range extends to the coastal and marshy forests of the central Goias Plateau.
Oncidium varicosum orchid, also called as The Veined Oncidium, Ampliglossum varicosum, Coppensia varicosa, Gomesa varicose, Oncidium euxanthinum, Oncidium geranense, Oncidium lunaeanum, Oncidium rodgersii, Oncidium varicosum var. charlesworthii, Oncidium varicosum var. concolor, Oncidium varicosum var. lindenii, Oncidium varicosum var. rogersii, Oncidium varicosum var. southorangense, Oncidium varicosum var. vexillarium, Oncidium vexillarium, is a species of the genus Oncidium. This species was first described by Lindley and Paxton in 1837.
IDENTIFY ONCIDIUM VARICOSUM ORCHID
The Veined Oncidium is native to Brazil, Bolivia and Paraguay (in the states of Goias, Bahia, Minas Gerais, Sao Paulo, and Parana). They usually grow in sunny positions in semi-tropical forests at heights of 600-800 m, but their range extends to the coastal and marshy forests of the central Goias Plateau.
This species is an epiphytic, medium sized, cool to warm growing orchid, which can reach a height of 19-38 cm, with ovoid, elongate, slightly compressed and rugose, 4-8 cm long and 2.0-2.5 cm wide pseudobulbs that have 2 to 3 apical, lanceolate, coriaceous yet flexible, curved usually 15-23 cm long, but sometimes they grow up to 30 cm leaves.
Blooming in the fall and winter on a basal stiff panicle, usually pendant, branched, lax and 91-150 cm long and carrying many non-fragrant, variable sized flowers. The flowers are arranged quite close to each other. Although their size is variable, the diameter of a typical flower rarely exceeds 3.8 cm. The flakes of both whorls are small and inconspicuous, dull yellow with bright red and brown stripes. The large lip is bright yellow and sometimes has red-brown spots on the front of the comb.
GROW AND CARE ONCIDIUM VARICOSUM ORCHID
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:
Oncidium varicosum orchid need a light source of 20000-30000 lux. The light should be filtered or dispersed, and the plants should not be exposed directly to the sun in the afternoon hours. Strong air movement should be ensured all the time. In the case of such suspended plants during particularly dry and hot periods, it may be necessary to fog several times during the day.
Temperature:
In summer, the average day temperature is 28-29 ° C, night 18-19 ° C, which gives a daily difference of 10-11 ° C. In winter the average day temperature is 24-26 ° C, night 12-13 ° C, with a daily amplitude of 13 ° C. Because these plants meet at lower altitudes, they should adapt to slightly higher growing temperatures.
Humidity:
The humidity should is a probable value of 75-80% for most of the year, which drops to around 65-70% in the dry season in winter. In the case of plants mounted on rootstocks, it is necessary to maintain high humidity of the air, and in the summer daily watering.
Substrate and growing medium:
Oncidium varicosum grows very well when it is tightly attached to a cork or tree fern rootstock, or in small pots or baskets with excellent drainage. The substrate should be coarse and permeable to allow the roots to dry quickly after watering, pieces of tree fern or bark is recommended.
Watering:
Cultivated plants should often be watered during active growth, more often from spring to early autumn, and less, relatively dry, for the rest of the year, and in the beginning of winter, 1-2 very dry months follow, but the roots must always dry quickly between watering. When new growths reach maturity in the autumn, the amount of water should be reduced.
Fertilizer:
During the active growth of the plants should be fertilized every week 1/4-1/2 of the recommended dose of fertilizer for orchids. Fertilization should be reduced or eliminated until new growths appear and a more abundant spring watering begins.
Rest period and repotting:
In winter, watering of cultivated plants should be limited, but must not be allowed to stay dry for a long time. As these plants do not tolerate separate soil around the roots, they should be repotted before it begins to decompose. Plants are best repotted when new roots begin to grow.
