The water goblets ( Cryptocoryne ), rarely also called water trumpets, are a genus within the family of the arum family (Araceae). Some of the 62 or so species are used as aquarium plants .

description

Vegetative characteristics

Water goblet species are perennial herbaceous plants . They thrive as aquatic and marsh plants and can live submerged (under water) and emersed (above water). They reproduce mainly by creeping, less often by upright rhizomes . The species are very variable in their appearance because they react to their respective environment. The parallel-veined, simple leaves are usually stalked and are in basal rosettes.

Generative characteristics

They only develop flowers during an emersed phase. Cryptocoryne species are single sexed ( monoecious ). The inflorescence consists of a stalked spathe (bract), which is expanded at the base to a cauldron. In the cauldron, the female and male flowers are arranged around the piston ( spadix ). At the bottom there are usually six fertile female flowers with a stamp consisting of the three carpels fused ovary , style and stigma. This is followed by a narrow, bald, sterile portion of the piston. There are 40 male flowers above it. The top part of the piston is again bare. The unisexual flowers are threefold.

There are berries formed.

Locations

In Cryptocoryne TYPES comes to water and marsh plants . They inhabit flowing water, its banks and residual water from floodplains.

Systematics and distribution

The name Cryptocoryne already used by Friedrich Ernst Ludwig von Fischer was published in 1830 as a valid genus by Heinrich Wydler in Linnaea. Volume 5, p. 428 prepared. Type species is Cryptocoryne spiralis (Retz.) Fisch. ex Wydler , which was first published in 1779 as Arum spirale by Anders Jahan Retzius . The botanical genus name Cryptocoryne derives from the Greek words kryptos for "hidden" and koryne for piston and refers to the flower organs hidden in the stalked inflorescence (spathe) which is enlarged to form a cauldron. Cryptocoryne fish. ex Wydler is Myrioblastus Wall. ex handle.

The genus Cryptocoryne belongs to the tribe Cryptocoryneae in the subfamily Aroideae within the family Araceae .

The genus Cryptocoryne is common in tropical India , South and Southeast Asia and New Guinea .

Importance for the aquarium hobby

100 to 150 species of different plant families are regularly offered in specialist shops for planting aquariums . These include about 10 to 15 types of water goblet. The other species are also cultivated, but keeping them makes special demands. This is especially true for most of the specimens of the Cryptocoryne cordata group ( Cryptocoryne blassii , Cryptocoryne purpurea , Cryptocoryne siamensis and others). Cryptocoryne hudoroi and Cryptocoryne spiralis , for example, are easier to look after . Many species also need an emersed culture for a successful culture and are therefore best kept in paludariums .

Water goblet species generally belong to the more susceptible aquarium plants . They are often sensitive to changes in water values. The so-called cryptocoryne rot , in which the leaves decompose , then often occurs .

There are also hybrids created in culture :

  • Cryptocoryne walkeri × Cryptocoryne nevillii (bastard water goblet): An artificial hybrid.
