Opuntia pinkavae ( German )

provided by wikipedia DE

Opuntia pinkavae ist eine Pflanzenart in der Gattung der Opuntien (Opuntia) aus der Familie der Kakteengewächse (Cactaceae). Das Artepitheton pinkavae ehrt den US-amerikanischen Botaniker Donald John Pinkava (* 1933).

Beschreibung

Opuntia pinkavae wächst strauchig mit ausgestreckten bis aufsteigenden Zweigen und erreicht Wuchshöhen von 10 bis 25 Zentimetern. Die schmalen bis breit eiförmigen, flachen und fest miteinander verbunden Triebabschnitte sind kahl oder leicht flaumig. Sie sind 6,5 bis 15 Zentimeter lang und 3 bis 11 Zentimeter breit. Die 1,5 bis 2 Zentimeter auseinanderstehenden Areolen tragen am oberen Teil auffällige, dichte Glochiden von 2 bis 4 Millimetern Länge. Die 1 bis 4 gelblich grauen bis weißlich grauen Dornen entspringen den oberen Areolen. Sie sind abwärts gerichtet bis aufrecht stehend und 3,5 bis 7 Zentimeter lang. Manchmal sind noch kleinere Dornen vorhanden.

Die magentaroten bis rosafarbenen Blüten sind 4,5 bis 7,5 Zentimeter lang. Die trockenen Früchte erreichen Durchmesser von 2 bis 2,5 Zentimeter.

Verbreitung, Systematik und Gefährdung

Opuntia pinkavae ist in den Vereinigten Staaten im Norden von Arizona und im Süden von Utah in Höhenlagen von 1370 bis 1560 Metern verbreitet.

Die Erstbeschreibung wurde 1997 von Bruce Dale Parfitt veröffentlicht.[1]

In der Roten Liste gefährdeter Arten der IUCN wird die Art als „Least Concern (LC)“, d. h. als nicht gefährdet geführt. Die Entwicklung der Populationen wird als stabil angesehen.[2]

Opuntia pinkavae

provided by wikipedia EN

Opuntia pinkavae, common names Bulrush Canyon prickly-pear or Pinkava's pricklypear,[2] is a species of cactus known only from northern Arizona and southern Utah. It grows in sunny locations in grasslands, on the edges of pinyon-juniper woodlands, on sandy or limestone soils.[3]

It was named for Dr. Donald Pinkava, professor emeritus at Arizona State University in Tempe. He studied Opuntia for many years. The species is one of the smaller members of the group, rarely more than 25 cm (10 inches) tall. Stems are green, flattened, up to 15 cm (6 inches) long. Flowers are magenta with yellow to magenta anthers and white styles. Fruits are tan, up to 3 cm (1.2 inches) long, dry when ripe.[4][5]

There is a bit of confusion concerning the correct scientific name. Specimens of O. pinkavae were distributed for years labeled as "Opuntia kaibabensis", a name that was never validly published.[6] Parfitt's original description coining the name Opuntia pinkavae and the treatment attributed to Pinkava in Flora of North America[3] suggest that the name was offered as a replacement for another allegedly unpublished name, Opuntia basilaris var. woodburyi. However, the varietal name was indeed validly published, but chromosomal comparisons between it and O. pinkavae show that they are not the same taxon. Bottom line in this is that Opuntia pinkavae remains an accepted name with no synonyms.[7]
