Harrisia taetra is a species of cactus found in Cuba.
Description
Harrisia taetra grows like a shrub and reaches heights of 1 to 2.5 meters. The somewhat articulated, cylindrical shoots have a diameter of 6.5 to 8 centimeters and are 0.3 to 1 meter long. There are eight to ten ribs. The stiff, needle-like, straight thorns, initially almost black, later turn whitish yellow. The two to three central spines are 4 to 9 centimeters long. The six to nine marginal spines are 0.7 to 4.4 centimeters long.
The flowers reach a length of 16.5 to 20 centimeters and a diameter of 12 to 15 centimeters. The light to golden yellow, broadly ovoid to somewhat spherical fruits are smooth and covered with a few tiny scales. They have a diameter of 3.8 to 7.2 centimeters and reach a length of 3.5 to 7.3 centimeters.[1]
Distribution
Harrisia taetra is widespread in Cuba in the Pinar del Río province on the Guanahacabibes Peninsula.
Taxonomy
The first description was made in 1981 by L. Alberto E. Areces-Mallea. The specific epithet taetra means 'hideous, hideous, ugly, repulsive'.
