Documents dating back to the 16th Century provide a unique insight into one of Darwin’s landmark studies, according to research. In 1862, Darwin presented the case that some plant species have two floral forms. But Darwin was not the first to observe ‘heterostyly.’ It had in fact been documented in 16th, 17th and 18th Century botanical records. But the true significance of the two floral forms was not realized at the time.
