Distribution, systematics and hazard
Parodia schumanniana is south of Brazil, in the south of Paraguay and northeastern Argentina spread on rocky scree slopes.
The first description as Echinocactus schumannianus by Ernst August Nicolai was published in 1893. Fred H. Brandt presented the way in 1982 to the genus Parodia. Nomenclatural synonyms are Malacocarpus schumannianus ( Nicolai ) Britton & Rose (1922, incorrect name ICBN article 11.4), Notocactus schumannianus ( Nicolai ) Fric (1928 ), Eriocactus schumannianus ( Nicolai ) Backeb. (1942, incorrect name ICBN article 11.4) and eriocephala schumanniana ( Nicolai ) Backeb. ( 1951). Was included among other Echinocactus grossei K.Schum. (1899 ) and Echinocactus buchheimianus Quehl (1899 ).
It can perform the following sub- types can be distinguished:
- Parodia schumanniana subsp. schumanniana
- Parodia schumanniana subsp. claviceps ( F.Ritter ) Hofacker & P.J.Braun
Parodia schumanniana subsp. schumanniana The shoots of Parodia schumanniana subsp. schumanniana reach stature heights of up to 1.8 meters. Often more than 30 ribs are present. The areoles are located on them 7 to 15 millimeters apart. It is formed a central spine, which, however, may be absent. The subspecies is widespread in Paraguay in the departments Paraguarí and Guairá and Misiones Province, Argentina.
Parodia schumanniana subsp. claviceps The shoots of Parodia schumanniana subsp. claviceps reach stature heights of less than 50 centimeters (possibly they are rarely up to 1 meter high). There are 23 to 30 ribs present on which the areoles are (rarely up to 8 mm ) from each other only 3 to 4 millimeters. There are a trained up three central spines. The subspecies is common in the Brazilian state of Rio Grande do Sul. The first description as Eriocactus claviceps by Friedrich Ritter was published in 1966. The name, however, was not correct according to ICBN article 11.4. Nomenclatural synonyms are Notocactus claviceps ( F.Ritter ) Krainz (1967 ), Parodia claviceps ( F.Ritter ) FHBrandt (1982 ), Notocactus schumannianus subsp. claviceps ( F.Ritter ) Doweld (1999) and Eriocactus schumannianus subsp. claviceps ( F.Ritter ) Doweld (2000, incorrect name ICBN article 11.4).
In the Red List of Threatened Species IUCN, the type is known as " Vulnerable (VU) ," ie, performed as endangered.
