Different colored cultivars of Gymnocalycium mihanovichii

Gymnocalycium mihanovichii is a species of plant in the genus Gymnocalycium from the cactus family(Cactaceae). The epithet of the species honors the Croatian- born Argentine shipowner and patron Nicolás Mihanovich (1881? –1940), who supported the trips of the Czech cactus specialist Alberto Vojtěch Frič to Paraguay .

description

The individually growing Gymnocalycium mihanovichii has a broad, spherical, gray-green, often reddish overflowing plant body that is 3 to 5 centimeters in height and diameter. The usually 8 ribs are narrow-edged and slightly notched. The 5 to 6 weak, flexible and slightly curved thorns are greyish-yellow, between 0.8 and 1 centimeter long and partly fall off.

The 4 to 5 centimeters long, bell-shaped to funnel-shaped flowers are yellowish-olive to light olive green. The light green stamens stand in two rows. The stylus is also light green, the scar yellowish. The fruits are spindle-shaped.

Distribution, systematics and endangerment

Gymnocalycium mihanovichii is widespread in Paraguay and northeast Argentina and grows at low altitudes up to 500 meters. The species was discovered there in 1903 by Alberto Vojtěch Frič.

The first description as Echinocactus mihanovichii was published in 1905 by Robert Louis August Maximilian Gürke . Nathaniel Lord Britton and Joseph Nelson Rose put them in the genus Gymnocalycium in 1922 .

Gymnocalycium mihanovichii is very variable, therefore numerous varieties have been described. In culture there are often also color forms - created by mutations in cultivated individuals - which are only viable in grafted form, since they can hardly or no longer assimilate due to the lack of chlorophyll in the plant cells.

In the Red List of Threatened Species of the IUCN , the species is listed as " Least Concern (LC) ". H. listed as not endangered.
