Use "calyx" in a sentence
"When the blossoms fall the apples stand upright on the tree, and the little pointed leaves that are on the blossom end of the apples, that we call the calyx, are all open, and at that time you can spray so as to get the arsenate of lead on the inside."
"It appears the tiny, crimson point of the bud which protrudes from the calyx is very sensitive, and more easily blighted by frost than any other bud."
"Blossoms single – calyx is urn-shaped, narrowing at the top – to its lining are fastened pistils and stamens – corolla consists of five (generally) broad petals, varying in colour from white to deep rose pink – buds are deep pink – fruit crimson in the autumn."
