A second large group is that of which the Melon and Hedgehog Cactuses are good representatives, which have sphere-shaped stems, covered with stout spines. We have hitherto spoken of the Cactuses as being without leaves, but this is only true of them when in an old or fully-developed state.
The stem is almost sphere-shaped, from 4 in. to 6 in. high, the tuberculated ridges about ¼ in. deep, and upon each tubercle is a tuft of about a dozen brown, radiating spines, with a long central one hooked at the point.
It seemed impossible, in that intervening space, to find a resting-place. Either the climber must keep going up, or he must slide down; he could not stop. But just here rose the danger. The Dome was sphere-shaped, and if he should begin to slide, his course would be, not to the point from which he had started and where the Saddle would catch him, but off to the south toward Little Yosemite.
The broad tongue-like spine is purple in colour, and as strong as iron; the three erect horn-like spines yellow, and as firm as the horns of an antelope, to which they bear a resemblance. The stem is sphere-shaped, grey-green in colour, and is divided into from fourteen to twenty-one stout wavy ribs, upon which the spine tufts occur at intervals of about 2 in.
