In Chinese wistaria, Wistaria sinensis, there are, says Goodale, about 7,000 pollen-grains to each ovule. The color of pollen is usually yellow ; but we often find it orange, reddish, nearly white, and in several Gilias in California it is bright blue. Pollen-grains are really single cells, and have two coats ; the outer is the extine, which may be smooth, variously sculptured, or even thickly set with spines (Fig. 81). These spines, as also the color, often enable us to tell the species of plant f
