What is the Latin term for "flower"?

The correct term for "flower" in Latin is "flos." This word directly translates to "flower" in English and is commonly used in botanical terminology to refer to the reproductive structure found in flowering plants. Understanding this term is essential in the study of botany, as many scientific names and classifications are derived from Latin.

The other options, while related to plants and may contain parts of the word "flos," do not accurately define "flower." "Florum," for example, is a genitive plural form that means “of flowers,” thus indicating possession, rather than defining the flower itself. "Florens" means "blooming" or "flowering," and "floreo" translates to "I bloom" or "I flower," which are action-based forms rather than the noun form for "flower." Thus, "flos" is indeed the most appropriate choice.
