This taxon is characterized by having its branches tomentose-hirtellous. The material seen from Colombia has leaves of generally small dimension, glabrous on both sides (in this respect differentiating them from the pubescent-leaved var dasyphylla), generally 12-32 (to rarely 45) mm long by 4-15 (to rarely 23) mm wide, obovate to broadly elliptic, rounded to subacute at apex, subsessile or with a petiolate portion 3-6 mm long, and with usually 4-5 pairs of lateral nerves faintly developed. The spines are generally axillary paired, but may also be terminal, and are mostly stout and 9-15 mm long. The branches of a season’s growth may be covered their entire length by short hirtellous, reddish-brown pubescence of incurved hairs, or this pubescence may be confined to the younger portion, as contrasted with other variations of R. aculeata, in which the short pubescence, if present, is confined to the apex of the uppermost nodes or else completely glabrous. Even upon exfoliation of the branches, the pubescence may be discerned in the var dasyclada.
