Catasetum, abbreviated as Ctsm in horticultural trade, is a genus of the Orchid family, subfamily Epidendroideae, tribe Cymbidieae, subtribe Catasetinae, with 166 species. Species of the genus Catasetum occur from Mexico to tropical America, with the majority in Brazil. They have thick, cigar-shaped pseudobulbs which are clustered. The leaves are pleated in the upper part and deciduous. The pseudobulbs become spiny after the leaves have dropped. The inflorescence is borne on the basis.

  • Catasetum, abbreviated as Ctsm in horticultural trade, is a genus of the Orchid family, subfamily Epidendroideae, tribe Cymbidieae, subtribe Catasetinae, with 166 species. Species of the genus Catasetum occur from Mexico to tropical America, with the majority in Brazil. They have thick, cigar-shaped pseudobulbs which are clustered. The leaves are pleated in the upper part and deciduous. The pseudobulbs become spiny after the leaves have dropped. The inflorescence is borne on the basis. It consists of very fleshy flowers that are unisexual, which is exceptional for orchids. The colorful male and yellowish-green female flowers are typically situated on different plants. Which type of flower a plant produces is determined by the conditions under which it grows. There are rare cases in which a single plant in intermediate conditions will produce both male and female flowers. These flowers are markedly different in size and color. At first, taxonomists even thought they were dealing with different species. The male flowers have a remarkable technique for the ejection of the pollinia. Sack-Shaped Catasetum (Catasetum saccatum), a tropical South American species, discussed briefly by Darwin, actually launches its viscid pollen sacs with explosive force, when an insect touches a seta. He was ridiculed for reporting this by the naturalist Thomas Huxley {Desmond, Adrian; Moore, James (1991), Darwin, London: Michael Joseph, Penguin Group, ISBN 0-7181-3430-3 page 510}.
  • Die Gattung Catasetum aus der Familie der Orchideen (Orchidaceae) umfasst etwa 150 Pflanzenarten, die alle in Mittel- und Südamerika vorkommen. Die Pflanzen wachsen meist epiphytisch. Es ist eine der wenigen Orchideen-Gattungen, deren Arten zweihäusig sind. Aufgrund ihrer interessanten Blüten werden sie gelegentlich kultiviert.
  • Catasetum es un género de unas 166 especies de orquídeas epífitas y flores masculinas y femeninas, de la tribu Cymbidieae de la familia Orchidaceae. Se distribuyen desde México por toda la América tropical hasta el Norte de Argentina, la mayoría se encuentran en Brasil.
  • Catasetum is een geslacht uit de orchideeënfamilie dat bestaat uit circa 150 soorten en natuurlijke hybriden.
  • Catasetum um género botânico pertencente à família das orquídeas (Orchidaceae). Foi proposto em 1822 por C.S. Kunth, essa descrição foi baseada em informações de L.C. Richard. publicado em Synopsis Plantarum 1: 330-331, sendo o Catasetum macrocarpum Rich. ex Kunth a espécie tipo.
