Thereis as a fact, in the position of the two stipular primordia here, a new formationwhich presents the appearance of one single leaflet. Comparative morphologywould here speak of a congenital concrescence, which is only a clumsy wayof stating the fact that where other species of Galium have two stipules here thereis only one present from thebeginning. Massart says thatin Sherardia arvensis all the.
