The Dieffenbachia ( Dieffenbachia ) are a genus of plants from the Arum family (Araceae). The approximately 51 Neotropical Dieffenbachia species are distributed from Costa Rica to Colombia . Some varieties are popular houseplants , on the one hand because of their striking leaves and on the other because they also thrive in shady locations. In tropical countries they are also planted as ornamental plants in parks and gardens. Contact with the sap of the plant can lead to rashes due to the calcium oxalate crystals it contains .
description
Dieffenbachia species are evergreen , perennial herbaceous plants that are sometimes shrub-like in size. The upright to prostrate, often thick stem is often only leafed in the upper area in older specimens. The alternate and usually spirally arranged leaves are usually clearly divided into leaf sheath, petiole and leaf blade. The mostly large leaf blades are simple, ovate to obscure-lanceolate and often patterned; some varieties are variegated.
Dieffenbachia species are single sexed ( monoecious ). Your typical Arum inflorescences not fall once their individual bracts in Araceae spathe called attention to. The durable spathe is tubular and somewhat constricted in the middle. The spathe tube is usually greatly elongated and remains until the fruit is ripe. In the case of the cylindrical piston (spadix), the female section hangs close to the spathe and the female flowers are arranged relatively loosely. The unisexual flowers do not have an inflorescence . The female flowers have a circle on four to five staminodes .
In the fruit cluster, the spathe tube splits open when ripe to reveal the fruit. The berries, which are scarlet or orange when ripe, stand close together on the cob.
The parts of the plant contain calcium oxalate crystals and are poisonous for people and animals (such as domestic cats who like to chew on indoor plants).
Its adaptability is very high, which is why it is well suited as a houseplant. Usually it absorbs much more water than it needs or can evaporate through its leaves. The excess liquid is transported to pores on the tips of the leaves, where the water is released. This process is called guttation .
Systematics and distribution
The genus Dieffenbachia was established by Heinrich Wilhelm Schott in 1829 with the type species Dieffenbachia seguine (Jacq.) Schott in the Wiener Zeitschrift für Kunst, Litteratur, Theater und Mode 1829, 3, p. 803. Heinrich Wilhelm Schott, director of the Botanical Garden in Vienna from 1845 to 1865, honored his long-time head gardener Joseph Dieffenbach (1796–1863) with the generic name Dieffenbachia . A synonym for Dieffenbachia Schott is Maguirea A.D.Hawkes .
The genus Dieffenbachia belongs to the tribe Dieffenbachieae in the subfamily Aroideae within the family of Araceae .
