'The plants, sometimes three or four feet high, grow in thickets. Many of the great fleshy pear-shape joints are solidly decorated along the edge with showy flowers, in the illustration reduced to about one-third the natural size. The fruit is conspicuous. When ripe the dark-red berries, two to four inches long, have crisp flesh of delicious flavor. The juice is used as a coloring fluid. The prickly pear below (Opuntia tenuispina) forms dense mats of spiny, interlacing branches which in early summer, after a shower, become flower beds of varied and delicate hue.
