Yucca reverchonii Trel.

Comments

Yucca reverchonii is endemic to the Edwards Plateau. J. M. Webber (1953) reported apparent hybrids of this species with Y. rupicola and Y. thompsoniana. S. D. McKelvey (1938–1947) indicated that Y. reverchonii occupies an area of the Plateau between those of Y. rupicola and Y. thompsoniana. K. H. Clary (1997) presented DNA evidence that confirms a close relationship among these three species as distinct entities.

Yucca reverchonii ( German )

Yucca Serie Rupicolae: Verbreitungsgebiet in Mexiko

Yucca reverchonii (englischer Trivialname: San Angelo-Yucca) ist eine Pflanzenart der Gattung der Palmlilien (Yucca) in der Familie der Spargelgewächse (Asparagaceae).

Beschreibung

Yucca reverchonii wächst solitär und stammlos. Im Alter bildet sie kleine dichte Gruppen mit 0,4 bis 1 Meter im Durchmesser. Die 25 bis 50 cm langen, 1 bis 2 cm breiten, steifen, grünen Laubblätter sind an den Blatträndern fein gezahnt.

Der über den Blättern beginnende, stark verzweigte Blütenstand wird 1 bis 2 Meter hoch. Die hängenden, glockenförmigen, weißen bis cremefarbenen Blüten weisen eine Länge von 3,5 bis 6 cm und einen Durchmesser von 1,5 bis 2 cm auf. Die Blütezeit reicht von Mai bis Juli. Die Pflanzen blühen schon im frühen Jugendstadium von vier bis fünf Jahren.

Vorkommen und Systematik

Yucca reverchonii steht nahe zu einem weiteren Vertreter der Sektion Chaenocarpa Serie Rupicolae Yucca rupicola. Jedoch hat diese die typischen gedrehten Blätter und ist leicht zu unterscheiden.

Yucca reverchonii ist in Mitteleuropa bei entsprechendem Schutz in den Wintermonaten frosthart bis −18 °C. Sie ist in den Sammlungen jedoch selten vertreten.

Yucca reverchonii ist in der Coahuila-Wüste im Grenzgebiet zwischen den USA und Mexiko in den Staaten Texas und Coahuila auf Kalksteinfelsen und im offenen Grasland in Höhenlagen zwischen 400 und 1000 Metern verbreitet. Diese Art wächst oft vergesellschaftet mit Yucca thompsoniana, Yucca rupicola und verschiedenen Kakteen-Arten.

Der botanische Name ehrt Julien Reverchon. Die Erstbeschreibung durch William Trelease unter dem Namen Yucca reverchonii ist 1911 veröffentlicht worden.[1]

Yucca reverchonii

provided by wikipedia EN

Yucca reverchonii [2] is a plant in the family Asparagaceae. It is native to the Edwards Plateau region of Texas, as well as to the Mexican states of Tamaulipas, Nuevo León, Coahuila, Chihuahua, Durango, Zacatecas, Aguascalientes, and San Luís Potosí. It is known as the San Angelo yucca and is closely related to Y. rupicola Scheele and Y. thompsoniana Trel.[3]

Characters that distinguish this species include:

  • Low, trunkless growth form, forming scattered colonies on limestone.
  • Leaves lack curling "hairs" on edges, and are very finely toothed.
  • Leaves nearly flat, straight (little or no twist), and usually less than 15 mm wide.
