Resumen:
Anarthrophyllum rigidum is a shrub species of wide distribution in the Patagonian steppe finding from the South of Mendoza until Santa Cruz. This species is forming patches of different sizes and under changing environmental conditions. So is that it is between the 1990 and 170 m above sea level in areas where the predominant soil is rocky until sectors with sandy soils. Anarthrophyllum rigidum presents also a high variability in its architecture to the amount of stems, height and diameter of the crown, etc. With the end of complement ecological studies is that base sequences of the chloroplast not coding region trnQ/rps16, were analyzed 31 individuals collected of the distribution of Anarthrophyllum rigidum. The sequenced fragment had 413 pb with three informative sites resulting in six different haplotypes. Greater diversity found North studied distribution, with a common haplotype in the range. One of the Andean population analyzed North distribution presented a unique and divergent haplotype from the rest of the found haplotypes. These results allow provide data to understand the biogeographical history of the species .
