In some Rosaceous plants an epicalyx is present, due to the formation of stipulary structures by the sepals. |
Epicalyx 3-lobed, lobes united at the base. |
With tree lavatera, the bracts of the epicalyx have grown together from the base, whereas the bracts of the mallows are completely separated. |
On top of this, the bracts of hollyhock mallow's epicalyx are broader and ovate, whereas musk mallow's are narrowly elliptic. |
An epicalyx, the outer series of what appears to be a double calyx, is common and is formed from the bracts or floral leaves of a reduced inflorescence. |
