When the calyx is inserted on the thalamus directly, so that it is the lowest whorl of a flower, it is said to be INFERIOR with respect to the pistil, which is the highest whorl, and is therefore said to be superior. In some cases, to be explained later on, the calyx seems to grow from the top of the pistil, when it is said to be superior in respect of the pistil, which in that case is inferior.

. A manual of Indian botany. Botany. THE FLOWER 85 of hairs or bristles, as in kukur-songa or kukshima, and such a hairy calyx is known as pappus (fig. 81). When the calyx is inserted on the thalamus directly, so that it is the lowest whorl of a flower, it is said to be INFERIOR with respect to the pistil, which is the highest whorl, and is therefore said to be superior. In some cases, to be explained later on, the calyx seems to grow from the top of the pistil, when it is said to be superior in respect of the pistil, which in that case is inferior. In some flowers, as in jaba and Cotton (see fig. 167), there is a whorl of green leaves below the calyx. This whorl of green leaves is usually known as epicalyx or whorl of bracteoles. Usu- ally a flower originates in the axil of a bract or bracteole. The side of a flower which is turned towards the bract or bracteole is said to be anterior, and the side turned away from it is said to be pos- terior. Corolla.—Corolla is the inner whorl of the peri- anth. The leaves, called petals, of which it is com- posed differ from the foliage leaves more than the sepals in colour, form, and structure. As a rule the petals are more or less brightly coloured, and serve to attract insects and birds to visit flowers. Hence the corolla is often called the attractive whorl. Occasionally the petals are green, like sepals, then they are called sepaloid or sepal-like. The petals are usually narrower near their base, or even have a. Fig. 8i.~Achene with Pappus.
