Catasetum albovirens is found in Brazil, coastal region of Pará State. It is reported specifically from the island of Marajó at the mouth of the Amazon River. It grows in a region that the rainy season lasts and the evenly warm climate rarely has a dry period.
Catasetum albovirens also called as The White and Green Catasetum, is a species of the genus Catasetum. This species was described by João Barbosa Rodrigues in 1877.
IDENTIFY CATASETUM ALBOVIRENS ORCHID PLANT
Catasetum albovirens is found in Brazil, coastal region of Pará State. It is reported specifically from the island of Marajó at the mouth of the Amazon River. It grows in a region that the rainy season lasts and the evenly warm climate rarely has a dry period.
It is a medium sized, hot growing epiphyte with stout, fleshy, white roots. It has curved, sulcate and rugose with age, 29 x 4 cm pseudobulbs enveloped by shaggy old sheaths and carrying 6, elliptic-lanceolate, very thick and leathery, plicate, 3 nerved, acute, to 24 x 6 cm leaves.
The White and Green Catasetum blooms in the fall on a basal to just above the base, erect then arching, to 40 cm long, to 12 flowered male inflorescence arising on a newly maturing pseudobulb and carrying small non-resupinate flowers. The flowers are about 37 x 50 mm and are white-green. Female flowers have not seen.
CATASETUM ALBOVIRENS ORCHID PLANT 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:
Catasetum albovirens are sun-loving plant and needs a light level of 30000-60000 lux. Unless the strong air movement found in the natural habitat can be duplicated, however, the grower should provide some shade (40-60 % shade). This species can be grown under lights if sufficient light intensity can be provided, and the plant certainly can be summered outdoors if their moisture requirements can be met.
Temperature:
In their natural habitat, the climate is evenly hot, moist, and tropical. This climate is almost the same year-round, with high humidity at night, even in the dry season, which is relatively short. The nighttime temperatures rarely fall below 18°C, with daytime highs generally from 29 to 35°C. The important thing is to maintain evenly warm conditions, and for this orchid the closer the night minimum is to 21°C, the better the plants will respond.
Humidity:
The White and Green Catasetum tolerate an environment with 40 - 60 % relative humidity during their growing season, but for optimal development of new growth and flowering, 70 % is recommended.
Substrate, growing media and repotting:
Catasetum albovirens can be grown in pot, container or wooden basket with fir bark, osmunda, tree fern fiber, charcoal, and sphagnum, in various proportions or combined with still other ingredients such as sponge rock, perlite, leaf mold, peat, and bark screenings as substrate. This plant can also mounted on wood. This option presupposes that the plant is sufficiently strong, that it is not so large as to be unwieldy when hanging from its mount, that the grower can provide adequate humidity for it during the growing season, that the conversion to mounting is done at the very beginning of the growth cycle, and that the species is known to adapt readily to this cultural practice.
It is recommended to repot every year and never wait more than two years. The optimal time for potting or repotting is when new growth on a plant emerging from dormancy is about 5 cm tall and the nubs have developed into new roots that are reaching for support.
Watering:
In its natural habitat it receives rainfall frequently even while dormant. Mounted, basket-grown, and unconventionally potted plant may be watered every sunny day during the growing season, provided conditions are such that they dry off relatively quickly. In the case of conventionally potted adult plants, it should not be necessary to water more than once or, at most, twice a week. This species like to dry out at least slightly between waterings.
Fertilizer:
Fertilize with an appropriate formulation at least every week during the growing season, or fertilize with a weak formula every time the plants are watered. It is important to begin regular applications of high-nitrogen fertilizer (such as 10-5-5) with a full range of trace elements. As the leaves begin to unfurl, and well before flowering, add a high-phosphorus formula to develop big, strong pseudobulbs capable of producing robust inflorescences. Any of the soluble products with a large second-digit number (for example, 3-12-6) constitute a good source of phosphorus.
Rest period:
Catasetum albovirens have a relatively short dormant period between leaf fall and new growth, and sometimes no dormancy at all, so the likelihood that at least some of their basic root system will survive from one growing season to the next increases. For this reason it is desirable to maintain a watering schedule, albeit reduced, during dormancy.
