corresponding to a nucellus, surrounded by an enveloping wall (cf. figs. 212 notes18,19,20,21). This wall may be regarded as representing the inner integument of the ovule, whilst the outer one is replaced by a leaflet. The monstrous ovules in the ovary of the Common Sallow (Salix Caprea, fig. 212 note29) show similar relations, except that the green, leafy structure upon which the nucellus of the ovule is inserted is folded along its midrib and has a fimbriated margin (fig. 212 note30). Of especial interest are the monstrous flowers of Rumex scutatus (cf. fig. 212 notes24,25,26,27,28), a plant common on the débris slopes of limestone mountains. In the normal flower of this plant the ovary is egg-shaped, and consists of three carpels united edge to edge (figs. 212 note22 and 212 note23). But in these monstrous cases it is enlarged from six to tenfold, and modified into a funnel-shaped tube open above (212 notes24,25,26,27). From this the ovule, also modified into a tube, sometimes
