Vegetative characteristics

The miracle flowers usually grow as perennial , rarely annual , herbaceous plants or often as subshrubs . They have a taproot that thin can be bulbous to rope-shaped or until thickened.

The aboveground parts of the plant are bare or hairy, often sticky. The shoot axes are upright to prostrate and unreinforced. The internodes have no sticky bands.

The leaves are stalked or sessile, each pair is approximately the same. The simple leaf blade is thin to thick-fleshy and the blade base is more or less symmetrical. There are no stipules .

Generative characteristics

The terminal or lateral, mostly zymous inflorescences contain 1 to 16 flowers. Each flower stands over a stalked involucrum . The long-lasting involucrum consists of five herbaceous to membranous bracts that are fused together .

The hermaphrodite flowers are fivefold. The five sepals are fused and petal-like. There are no petals. The flowers are chasmogamous and / or kleistogamous . In the case of cleistogamous flowers, the flower envelope is a small dome. In the case of chasmogams, the inflorescence is radially symmetrical to slightly zygomorphic , bell-shaped to funnel-shaped, with the corolla tube expanding gradually or abruptly. The three to six stamens rise above the bracts. The styles extend beyond the stamens, their stigmas are head-shaped.

Usually an “ anthocarp ” is formed. The anthocarp is radial symmetry and usually has five round to angular ribs. The shape of the anthocarp is obovate, ellipsoidal to almost spherical. The surface can be smooth, leathery, bald or hairy.

The basic chromosome numbers are usually x = 9.

Systematics and distribution

The genus Mirabilis was established in Species Plantarum , 1, page 177 in 1753 . The type species is Mirabilis jalapa L. The genus name Mirabilis comes from the Latin word mirabilis for wonderful.

The genus Mirabilis belongs to the tribe Nyctagineae within the family of the Nyctaginaceae .

Anton Heimerl divided the genus Mirabilis into six sections in 1934 :

  • Section Mirabilis : It contains about ten species from the southwestern United States through Mexico to northern Central America .
  • Section Mirabilopsis Heimerl : There is only one species from the southwestern United States to northern Mexico.
  • Section Oxybaphoides A.Gray : It contains about 17 species from the southwestern United States to northern Mexico, South America, and South Asia .
  • Section Oxybaphus (L'Heritier ex Willdenow) Heimerl : It contains about 25 species from the southwestern United States through Mexico and Central America to South America.
  • Section Paramirabilis Heimerl
  • Quamoclidion (Choisy) A.Gray Section : Contains about six species from the southwestern United States to northern Mexico.

The taxonomy of species is often difficult because forms that differ greatly from one another morphologically and ecologically have no distinguishable reproductive characteristics. This problem is particularly evident in the Oxybaphus section due to autogamy , xenogamy and high chromosome numbers .

The genus Mirabilis thrives in temperate to tropical areas, especially in North and South America. At least one species is also native to South Asia. The miracle flower ( Mirabilis jalapa ) was spread worldwide by humans.
