Superficially similar to a willow, this tree’s trunk comprise numerous intertwined stalks and tubes, which give the appearance of living veins. Most of the stalks terminate in clusters of ordinary leaves from which the tree sustains itself through photosynthesis. About one in five, however, ends in a downward facing tube, from which a cluster of fine fibers trail from, resembling an elongated paint brush, hence the name. The tree is able to secrete a variety of liquids, ranging from sweet smelling nectar to insect pheromones in order to lure small creatures. Once in contact with the fibers, a reflex action retracts the fibers along with any entangled creatures into the trunk for digestion. While the largest specimens are capable of trapping human-sized creatures, casualties are rare, as any seasoned adventurer will recognize the tree from a safe distance and give it a wide berth. The one regrettable exception is the rare case where a dryad has bonded with said tree, charming travelers and luring them to the tree. Attempts to domesticate the tree into dwarf varieties suitable for household pest control have thus far been unsuccessful, as the tree’s sticky sap has proven a messy nuisance.
