All of the petals in a flower are collectively referred to as the
corolla. A spring beauty (Claytonia spp), for example, has a corolla of
five petals.  Similarly, the sepals are collectively known as the
calyx.  So refer to the corolla if you mean to refer to all of the
petals together.  The corolla and calyx together comprise the perianth.

Corolla refers to all the petals as a group.
>When is it proper to refer to calyx rather than sepal?
Calyx is the group name for the sepals.

Some authors reserve these terms for when the group is fused into a
cylinder, as in daffodils.

What names do these authors use for the groups of unfused petals and
sepals?
