Hatiora

Hatiora gaertneri

Hatiora is a genus of flowering plants of the cactus family ( Cactaceae ). The botanical name honors the English mathematician, astronomer and explorer Thomas Hariot (1560-1621) and is an anagram of his name.

Description

The species of the genus Hatiora growing epiphytic or lithophytic. You are branched shrubby and rich. Your first upright and later spread or overhanging or suspended driving sections are limited in their growth in length. The cylindrical, winged, angular or flattened drive sections are up to 5 inches long. They arise singly or in groups areoles at the top of older engines sections. Blühfähige areoles are terminally to the drive sections and flowing together there. Thorns absent or are formed as soft bristles.

The radial symmetry, bell-shaped, yellow, pink or red flowers appear at the shoot tips and open day. Your bald Perikarpell is angular, winged or drehrund. The corolla tube is short.

The small spherical fruits are bald. They contain brown or black seeds of 1 millimeter in length.

Dissemination

The genus is widespread in southeastern Brazil.

System

The first description of the genus was published in 1834 as Hariota by Augustin- de Candolle Pyrame. Under the rules of Internationalern code of botanical nomenclature, however, this name is not valid because Michel Adanson in 1763 had given a genus name. Nathaniel Lord Britton and Joseph Nelson Rose formed in 1915 from the original name of the genus, the anagram Hatiora. The type species of the genus is rhipsalis salicornoides.

The genus is divided into two subgenera. The subgenus Hatiora is characterized by rotating round or cylindrical, ribbed never drive sections and a round in cross-section Perikarpell. The Rhipsalidopsis has flattened engine sections and an angular or winged Perikarpell. Belong to the genus of the following types:

  • Subgenus Hatiora Hatiora herminiae (Porto & Castell. ) Barthlott
  • Hatiora salicornioides ( Haw. ) Britton & Rose
  • Subgenus Rhipsalidopsis ( Britton & Rose) Barthlott Hatiora epiphylloides (Porto & Werderm. ) Buxbaum Hatiora epiphylloides subsp. epiphylloides
  • Hatiora epiphylloides subsp. bradei (Porto & A.Cast. ) Barthlott & N.P.Taylor

And Hatiora × graeseri Barthlott ex DRHunt - the so-called " Easter Cactus " - a hybrid of Hatiora gaertneri and Hatiora rosea.

Synonyms of the genus are Hariota DC. (1834, nom. Illeg. ICBN article 53.1 ), Rhipsalidopsis Britton & Rose ( 1923), Epiphyllopsis A.Berger (1929) and Pseudozygocactus Backeb. (1938).
