Such axillary stipules may also appear combined withinterpetiolar stipules, and then there is a very peculiar construction, becausethe interpetiolar stipules unite with one another to form a sheath-like body,which then serves as a protection to the bud. We find this in a species ofGaertnera w^hich I collected in Ceylon (Fig. 247). The origin of the con-struction is shown in Fig. 247, I, where between the leaves of the youngestleaf-pair, the interpetiolar stipules are visible. If now we suppose that theupper side of the base of each leaf shares in the stipular formation, the. Fig. 247. Gaertnera sp. (Ceylon). Bud in transverse section. I, liiglierup ; II, lower down. The stipules areshaded. interpetiolar stipules would in a certain degree be united across the surfaceof their leaves, and thus would arise the peculiar condition which we havein this plant. The stipular sheaths are provided with numerous glands, andthese it may be assumed aid in the protection of the bud. Gunnera. Some species of Gunnera possess remarkable axillary genus contains forms of very different dimensions, and the axillarystipules are only found in those which possess a thick tuberous stem, andwhose terminal bud is therefore very massive. For its protection, organs aredeveloped which are absent in the species with more slender stem, like and the small New Zealand species. We have in this one ofthe most striking relationships between size and formation of organs withinone genus. The ax
