In the lily and passion-flower they are linear and loosely attached by their centre, and are easily moved about? being called versatile. They are often globose or oblong, and attached to the side of the filament.

They are often globose or oblong, and attached to the side of the filament. Each consists of two cells, which open either by a slit, or pores at their apex, as in rhododendron; or by valve-like lids, as the sweet bay. The cells contain a matter like powdery dust, generally of a yellowish colour, called pollen^ which, on Fig. being examined with the microscope, will be seen to con- sist of definite bodies, varying in size and shape in dif- ferent plants (fig. 7, a), being globose, oblong, like grains of wheat, or tri-lobed. Their surface is either dotted, striated, smooth, rough, or prickly. On the application of moisture, they after a time burst and protrude a thread-like body called the pollen tube (fig. 7, d), which is the essence of fertilization. {See Fertilization.) The Pistil.—The pistil or pistils, there being often more than one in a flower, is seated on the ovary, and, when perfect, consists of two parts, the lower part being.
