What is the scientific name for the plant commonly known as the daffodil?

The scientific name for the plant commonly known as the daffodil encompasses a classification that reflects both specific and broader group designs. The option citing Narcissus spp. is a broader classification that refers to multiple species within the Narcissus genus, including various types of daffodils.

While Narcissus pseudonarcissus and Narcissus tazetta represent specific species of daffodils, the abbreviation "spp." stands for "species plural" and is generally used to refer to any or all species within a given genus. Thus, it accurately captures the common knowledge that there are multiple daffodil species under the Narcissus genus.

The choice indicating "sp." refers to a single unspecified species, making the plural form more suitable when discussing the well-known diversity within daffodils. This understanding of biological classification is essential for identifying plants in horticulture and botany, as it allows for recognition of both specific and generalized groups, ensuring a comprehensive grasp of the plant's lineage.
