 Daisy
florets
The Asteraceae have two basic kinds of individual flowers. One of the key steps in identifying daisies is to be able to recognise these. |
 |

 |
 |
| Tube flowers have radially symmetrical corollas. The lobes are often short (as above). However in thistles they are very long | Ligulate (or ray) flowers have one side of the corolla extended on on side into a
ligule. The ligule is often a long strap, but can be quite short
(e.g. the flower on the right)
|
Many daisies have tube flowers in the centre surrounded by long ligulate
flowers resembling petals
Other species have only tube flowers, and others only ligulate flowers.
|
Sometimes the bracts around the head (phyllaries) resemble ligulate
flowers, but if you check the base of these bracts you will see that they
are not flowers
