Primocane fruiting plants bear on first year canes (i.e. primocanes). Typically the cane will come up in the spring, and once it reaches a certain (genetically predetermined) number of nodes of growth it initiates flower buds from the tip of the cane downward. These then bloom and fruit, with the fruit typically ripening in late summer and fall.
A floricane is a second year cane i.e. one that has overwintered once. Plants that are floricane fruiting send up new canes in the spring, and don't initiate flower buds until cued by shorter daylength and cooler temperatures in late summer and fall. These flower buds remain dormant along with the rest of the cane until spring, when they flower with the fruit ripening in the summer. Traditionally floricane fruiting cultivars have been termed summer-fruiting while primocane fruiting cultivars (which incidentally also fruit on the lower half of their floricanes) have been termed everbearing or fall-fruiting.
Hope this helps any confusion.
