Bracts can appear leaf-like or petal-like: such as a reduced leaf, or modified leaf, that subtends a flower or inflorescence, or sometimes occurs along a stem. Or, on occasion, bracts are highly colored and surrounding tiny flowers, such as with poinsetta, bougainvillea, and dogwood. In conifers - within a cone, the structures arising from the cone axis that support the ovules are often called bracts (strictly, they are sporophylls).
