Abstract: During the spring season (February-April) 2015, the natural occurrence of secondary capitula phenotype was found in Calendula officinalis L. in DAV University Campus, Jalandhar, Punjab, India. Out of all C. officinalis plants grown,5.3% were found to bear secondary capitula emerging from primary capitula. One plant was found to bear a tertiary capitulum. A comparative analysis of this dataset of naturally occurring secondary capitula was made with the previous reports of secondary capitula phenotype in C. officinalis induced by Gibberlic acid (GA) treatment. The observations were found to be in congruence with a previous report. Further, a possible phytopathogen i.e. phytoplasma, was also addressed as a potential cause of the phenomenon.
