Unlike many modern botanists, Lewis clearly understood the difference between a peduncle (the stalk that holds the inflorescence and arises from the bulb) and a pedicel (the stalk that holds an individual flower). In describing the inflorescence, Lewis states that the "10 to forty flowers" are on a "footstalk." The term "footstalk" is equal to "pedicel" so that the individual flowers are pedicellate, or "on a pedicel."
Glossarypedicel—"The stalk of a single flower in an inflorescence."
peduncle—"The stalk of an inflorescence or of a solitary flower." The word comes from pedunculus, a diminutive of the Latin pes, ped-, meaning foot.
inflorescence—"A flower cluster of a plant, or, more correctly, the arrangement of the flowers on the axis."
