Mr E A Goldman Contr U S Nat Herb 16 352 353 1916 speaks of it as follows

We first saw this remarkable cactus on the coastal plain near Santo Domingo, about 30 miles north of Matancita and here made a collection. From this point southward it was noted at intervals on the plains as far as the Llano de Yrais and on the lower and more sandy parts of Magdalena Island. The stems grow 1 to 3 meters in length and are nearly prostrate, and from this habit and their long whitish recurved spines have aptly been likened to huge caterpillars. The growing ends of the branches...
