Pachycereus Pecten-Aboriginum Cacti. Hairbrush Cactus.

The Pachycereus Pecten-Aboriginum Cactus is one of the largest columnar variety of cacti in the world. This giant branching evergreen succulent can reach heights of 15m. Many erect branches, deep green in colour have 10-12 acute ribs with areoles up to 1cm in diameter. There are few spines, but what are present are sharp and rigid, white to grey in colour. 1-2 central spines between 1-9cm long are erect or slightly curved in mature plants with 8-12 short spreading ones. In more mature specimens the areoles only bear a tuft of dense bristly spines, the larger of which is 1-3cm long.
White flowers between 5-7.5cm are nocturnal and are closed by midday the following day. The fruit is densely covered with long goldes spines and splits apart when ripe to show a layer of edible red flesh and shiney black seeds.
