I think Asteraceae (Compositae) is the largest plant family in the world.

Asteraceae

Haees Al- Jowary

Asteraceae, also known as the Compositae, is the largest family of flowering plants. The family has a worldwide distribution and is found from sea level to the highest mountains.

Family of Asteraceae or Asteraceae (Asteraceae or Compositae). It is represented by more than 20,000 species, grouped in 1150-1300 (according to various specialists in plant taxonomy) genera. Among the plants of this family are sunflower (a genus that includes more than 100 species; technical and decorative culture; this genus includes Jerusalem artichoke), Chinese asters, Alpine and others, marigolds, marigolds, dahlias, zinnia , Daisy (ornamental plants), chamomile, milk Thistle, cornflower, burdock, chicory, dandelion (medicinal plant and weed).. . And how many more unnamed...

The largest, and both in size and weight (but not in height — here the primacy for the evergreen Sequoia named Hyperion), today consider Pando. No, we are not talking about a rare black and white bear, but about a giant colony of poplar aspen (Populus tremuloides), growing in the us state of Utah. Pando (from the Latin " spreading») it consists of more than 40,000 trees, United by a root system and a common origin, which was confirmed by genetic analysis. The root system of Pando covers an area of more than 43.6 hectares, the grove weighs more than 6000 tons, and its age is estimated at several tens of thousands of years. So it is not only the largest and heaviest plant, but also one of the oldest living organisms. Note that each individual Populus tremuloides tree rarely survives the 100-130 year mark, but modeling the age of the Pando root system shows that it could have appeared at least 14,000 years ago (other estimates are up to 80,000 years). It is noteworthy that all the trunks of Pando are clones, that is, they are genetically identical, and at the same time they are all male, and the spread of the colony occurs with the help of root offspring. It is also interesting that the grove was identified as a single organism only in 1976; research on this unique organism (usually clonal poplar colonies do not exceed 0.1 ha in area) continues today.

Asteraceae

Asteraceae in terms of species composition

Orchidaceae has most species currently recognized, c. 26-28,000.

Asteraceae (Compositae) has around 30,000 species in the World.

Asteraceae leads the list, closely followed by Orchidaceae.

compositeae (asteraceae) is one of the richest and widespread family of flowering plants

yes, Asteraceae is the largest plant family around the world

very Good - Thank you very much

Asteraceae about 32,913 species are gathered, divided into about 1911 genera.
