“ The sour-sop is the fruit of A. muricata, native of the West Indies. The plant, which is a small tree, has become naturalized in some parts of India where it is extensively cultivated, as elsewhere in the tropics. It is covered with soft prickles, is of a light-greenish hue, and has a peculiar but agreeable sour taste, and a scent resembling that of black currants. The sweet-sop is produced by A. squamosa, also a native of the West Indies and widely cultivated in the tropics. ”
