Tacinga is a genus of plants from the cactus family(Cactaceae). The botanical name of the genus is an anagram of the word "Catinga", the distribution area of the genus in the Brazilian Caatinga .
description
The species of the genus Tacinga grow shrubby, are sometimes weakly climbing or creeping. The green shoots are round and stick-like in cross section, sometimes slightly pressed or round, elongated or elliptical and somewhat flattened. They can be articulated and become woody with age. The strongly receded leaves are small, slender and cylindrical. From the black, with glochids occupied Areoles spring 2 to 3 short spines , which also may be missing and fall soon.
The pale yellow, green to purple to brown mottled flowers arise along the segment edges or near the tip of the shoot. They open during the day or are open day and night. The spherical to elongated, shoot-like pericarpel is covered with tiny scales and glochid-bearing areoles.
The spherical to elongated, fleshy fruits are green, white, brownish or reddish. The remnant of the flower falls off quickly. They contain whitish, almost spherical to pear-shaped seeds that are slightly compressed on the sides and 3 to 4 millimeters long.
