The Santiago Island Amaranth is known only from the herbar specimens, which were collected once in the year 1891 and for the second - and last time between 1905 and 1906.

This species with its small, hirsute leaves, was very well adapted to dry habitats, but not to the appetite of introduced donkeys, pigs and above all goats (Of which the estimated number in the year 1980 on the Isla San Salvador alone was 80000 to 100000!).
