• Text: "Likewise I argue that Trianthema (three-flowered plant) and Dendranthema (tree-flowered plant) ought to be treated as first declension feminine singulars, as done by the original authors (or by Linnaeus's son, in the case of Trianthema L.), not as a second declension neuter plurals (three-flowers, tree-flowers)."

• Text: "Generic names apparently ending in -anthema, such as Trianthema (Aizoaceae) and Dendranthema (Asteraceae), are neuter plural in Latin and are to be corrected to neuter singular -anthemum, thus Trianthemum and Dendranthemum."
