Catasetum kleberianum

 

Common Name Kleber's Catasetum [Kleber de Lacerda Jr., Brazilian discoverer of species current]

 

Flower Size 1 5/8" [4 cm]

 

This is a medium sized, warm growing Brazilian epiphytic species from Amazonas state and grows on trees in flooded forests along the Rio Preto do Igapo-Acu with fusiform pseudobulbs carrying oblanceolate, plicate leaves that blooms in the fall on a basal, suberect, racemose, 10" [26 cm] long, several [11 to 14] flowered inflorescence arising on a newly matured pseudobulb carrying longer lasting flowers than normal for this genus.

Give a very short rest period with humid conditions year round with light to moderate shade.

DESCRIPTION: This is a medium sized, warm growing Brazilian epiphytic species from Amazonas state and grows on trees in flooded forests along the Rio Preto do Igapo-Acu with fusiform pseudobulbs carrying oblanceolate, plicate leaves that blooms in the fall on a basal, suberect, racemose, 10 [26 cm] long, several [11 to 14] flowered inflorescence arising on a newly matured pseudobulb carrying longer lasting flowers than normal for this genus.   (Souce:  https://www.orchids.org/grexes/catasetum-kleberianum )

 

 

Culture:

 

Catasetum kleberianum is found in Brazil, Amazonas State, municipality of Borba. It grows on trees in flooded forest along the Rio Preto do Igapó-Açú.  Catasetum kleberianum also called as Kleber's Catasetum, is a species of the genus Catasetum. This species was described by Pedro Ivo Soares Braga in 1994.

It is a medium sized, warm growing epiphytic species with fusiform, to 10 cm long and 2.5 cm wide pseudobulbs carrying oblanceolate, plicate, 25 cm long and 6 cm wide leaves.

Kleber's Catasetum blooms in the fall on a basal, suberect, racemose, 26 cm long, 11 to 14 flowered inflorescence arising on a newly matured pseudobulb carrying longer lasting flowers than normal for this genus. The flowers are about 40 mm in diameter with coloration of peduncle and pedicels light green, irregularly tinged with red-brown; sepals and petals cream-colored, marbled with yellow-brown; lip canary yellow; column greenish spotted with red-brown; antennae and anther yellow-green. The female flowers are not seen.

The key to identify this species is its lip canary-yellow with denticulate margins (rather than crenulate as in Catasetum tenebrosum), and in the form of a rounded triangle, with a less-pronounced callosity (compared with Catasetum spitzii, to which it is vaguely similar). The lateral sepals tend to be pendent.

 

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 kleberianum 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:
 
Kleber's 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 kleberianum 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 kleberianum have a relatively short dormant period between leaf fall and new growth. When the plants are leafless and no new growths are visible, the grower must respect their state of dormancy. Watering frequency should be reduced during dormancy. Fertilization should stop completely during this period. In the springtime, at the beginning of the growth cycle, water should not be made regularly available for the newly developing roots until the new growth is at least 5 cm tall.
