Cleome flowers (lat. Cleome), or cleome, belong to the genus of annual or biennial plants of the Cleomaceae family, growing throughout the globe in areas with a warm and temperate climate and numbering about 70 species. For the peculiar shape of the inflorescences, the Germans call the cleoma flower "spinenpflanze", which means "spider plant". Unusual brushes look like an explosion, a splash of champagne - you may not like this plant, but it is impossible not to pay attention to it.

The family of Cereals predominantly includes herbaceous annuals or perennials, although there are shrubs and even trees. All cultures are united by a common structure:

  • stem
  • leaves
  • flowers
  • inflorescences
  • fruit
  • seed

The stalks of cereal crops are hollow inside and consist of knees connected by swollen and therefore clearly visible internodes. Each of them has a baffle and the stem looks like a baffled hollow tube. Stems with such a structure are commonly called straws in botany.

In rare exceptions, the inside of the knee is filled with loose tissue, like sugarcane, sorghum, corn. In cereals, secondary roots are well developed, and the main root either stops growing early or stops growing after germination. The leaves of cereals are vaginal, the edges of the vagina are rarely closed.

The leaf plates are most often ribbon-like, narrow, sometimes folded in half or rolled up in a tube. Inflorescences can be different, but collected from miniature spikelets. Most often, the spikelets are folded:

  • in panicles
  • to the sultans
  • in a simple ear
  • in a spike-shaped panicle
  • into a complex ear

The taxonomy of the family has repeatedly changed over the past century, then it was divided into 2, then into 12 subfamilies. For example, at one time the Prosovs belonged to the Tsentotekovs. Modern taxonomists have divided cereals into seven subfamilies:

  • Feather grass
  • Bamboo
  • Millet
  • Bluegrass
  • Chloride
  • Centotech
  • Reed

Below are lists of cereals belonging to the various subfamilies.
