They are imbricated upon the calyxes of most of the compound flowers. You have seen in buds, how important the scales are to protect the embryo plant during the winter.

Tendrils, or claspers, are threadlike, or filiform appendages, by which weak stems attach themselves to other bodies for sup- port ; they usually rise from the branches, in some cases from the leaf, and rarely from the leaf- stalk or flower-stalk. You have here the representation, Fig. 40, of a tendril. Tendrils are very important and characteris- tic appendages to many plants. In the Trumpet flower and Ivy, the tendrils serve for roots, planting themselves into the bark of trees, or in the walls of buildings. In the Cucumber and some other plants, tendrils serve both for sustenance and shade. Many t of the papilionaceous, or Pea blossom plants, 'have twining tendrils, which wind to the right and back again. Some plants creep by their tendrils to a very great height, even tc the tops of the loftiest trees ; and seem to cease ascending only because they can find nothing higher to climb upon. One of our most beautiful climbing plants is the Clema- tis virginica, or Virgin's bower, which has flowers of a brilliant whiteness ; in autumn, its pericarps, with the long pistils remaining upon them, Took like festoons of rich, yellowish fringe. 249. Pubescence includes all down, hairs, woolliness, or silkiness of plants. The pubescence of plants varies in differ ent soils, and with different modes of cultivation. The species in some genera
