The sitimtion will be evident from the consideration of a typical case, that of the Rattlesnake plantain, Peraininm puhesceus (fig. 25). Its rosettes of leaves do not appear until late in the season, but persist through the winter and well into the following season. With its pros- trate stem fixed on the ground, antl its slow growth, it has no means of surmounting a covering of leaves, so that if deeply covered it is inevitably smothered. Not only is it deprived of light during the winter; it seirds up no erect shoots to pierce the leafy blanket in the spring. The plant grows in vai'ied habitats, such as ]-ocks, hemlock. Fig. 25.
