Raceme
Definition:
(n.) A flower cluster with an elongated axis and many one-flowered lateral pedicels, as in the currant and chokecherry.
Example Sentences:

(2) In contrast to the enantiomeric discrimination observed with racemic amine, the individual isomers were metabolized at approximately the same rate.
(3) Routine enantiomeric analyses were successfully carried out on samples taken from animals dosed orally with the racemic drugs, providing important data on the possible levels of exposure to individual enantiomers during toxicity testing.
