Read about Catasetum in the Standard Cyclopedia of Horticulture 

Catasetum (Greek for downward or backward, and bristle). Orchidaceae. Epiphytic or terrestrial orchids, requiring hothouse conditions.

Stems short fusiform: lvs. plaited, membranaceous: scapes basal; fls. in racemes, globose or expanded; labellum fleshy; column erect, provided with sensitive appendages which, when touched, cause the pollen- masses to fly out; pollinia 2. The genus includes Monachanthus and Myanthus.—There are about 50 or 60 species in the American tropics.

The flowers are in racemes or spikes, firm in texture, and white or in shades of green, yellow, brown or purple. Catasetums are not much cultivated, since most of the species are not showy, but they are interesting to the botanist and amateur because of the striking ejection of the pollen-masses. Gardeners often have trouble with catasetums, but they are not difficult to grow if given good care. They need a high temperature, long period of rest, and free supply of water during the growing season. They are grown in both pots and baskets. Readily propagated by dividing the plants at the base; also from very ripe pseudobulbs cut in pieces and put in sand. For culture, see Orchids.

Species
See text.

Catasetum Rich. ex Kunth 1822, is a genus of the Orchid family (Orchidaceae), 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.
