Notes on delimitation
- This is one of the 'natural' families, and as such there is no problem in delimiting the family, since all members can be properly attributed to it with careful examination.
- The number of subfamilies in the Compositae has risen to over a dozen (and likely to rise still further), with the somewhat impractical expansion of the number of tribes to 30. From a purely practical point of view, in terms of teaching and fieldwork, there is little wrong in recognizing the tribes as proposed by Bentham (1873), but recognizing a separate Barnadesieae and Liabeae, and combining the Helenieae within a broader circumscription of the Heliantheae.
- Within the Neotropics I currently recognize 13 tribes as possessing native or naturalized species; only the tribe Arctotideae is absent although some species may well be cultivated.
- A key to the tribes found in the Neotropics is provided below, together with diagnostic/conspectus-like descriptions of each of the tribes above.
Distribution in the Neotropics
- Found throughout the Neotropics, although species numbers are restricted in rainforest and extensive aquatic habitats. The family is particularly common in montane habitats, disturbed areas and in semi-arid regions, and is common (as weeds) in most cultivated regions.
Distinguishing characters (always present)
- The combined presence of diminutive flowers (termed florets) massed into a capitulum surrounded by protective involucral bracts (termed phyllaries) in one or more series.
- Gamopetalous corolla.
- A style with two apical style arms (usually, but not always, divided).
- 5 anthers united into a cylinder around the style and dehiscing antrorsely.
- Pappus of capillary setae or of scales (although sometimes absent).
- Fruit an achene (or more correctly a cypsela).
Key differences from similar families
Close examination will place all members of the Compositae within the family without any great difficulty. However, superficial examination may well place some taxa, albeit very rarely, into other families. Both vegetative and fertile material of Ichthyothere is sometimes misplaced in the Commelinaceae. Material from other families is often placed in the Compositae, most notably members of the Acanthaceae, Amaranthaceae, Labiatae and sometimes Rubiaceae. All of these families are instantly thrown out because they have:
- Free stamens.
- Capitate stigmas.
- Typically distinct calyces.
- No pappus -like structure.
- Very distinctive fruiting structures.
Allied families, such as the Calyceraceae and Goodeniaceae, and other families historically placed close to the Compositae, such as the Dipsacaceae and Valerianaceae, are similarly easy to distinguish upon close examination.
Number of genera
- c. 1600 total for family globally; total as yet unknown in the Neotropics.
Useful tips for generic identification
- It is especially important to make sure that fertile material is collected that shows all floret types open and ideally with mature achenes - although achene maturation will usually take place whilst material is being dried in the press.
- In many genera pappus length varies considerably between flowering and fruiting material, as does achene shape and size (especially in those taxa developing beaked achenes), and often receptacular paleae grow (and can change colour) considerably in fruiting capitula.

Notable genera and distinguishing features
- Within the Neotropics there are very many notable genera, and certainly too many to separate out. In each ecostystem, within each of the countries in the area, there may well be dominant, or abundant, or otherwise noteworthy Compositae.
- With the exception of the rainforest, and extensive aquatic habitats, the family is present in most of the ecosystems found in the area.
- In each of the main countries in the Flora area there are very high percentages of native taxa, and significant percentages of endemics. Many weedy taxa, from both New World and Old World, exist within the Flora area and there are many Neotropical taxa naturalized within others.

The literature on the Compositae is vast, although within the Flora area there are relatively few full (or state-based) floristic treatments for the family (Argentina - in progress, Guianas, Venezuela, Mexico - in progress, Santa Catarina, Brazil - in progress). Checklists exist for several countries (e.g. Argentina, Bolivia, Peru, Ecuador), but some floras are historical and considerably out of date (e.g. Brazil).
There are very few Flora Neotropica monographs available for any part of the family.
The Kubitzki volume of the Families and Genera of Vascular Plants on the Asterales, vol. VIII, covers the family, at tribal and generic level, comprehensively for the first time with keys to most taxa down to genera. Significant literature is listed at length in this volume.
