Henslow draws attention to the importance of the class of observations illustrated in this paper, explaining that by referring all the floral organs back to their vascular cords or 'axial traces', their real origins can be discovered, whenever their developmental history is incapable of showing them. He shows how the cords, taken as 'floral units', can give rise to axes as well as all kinds of floral appendages.
